Metabolism Boosting Foods, Metabolism Boosting Supplements, and Activities!

Let’s talk about metabolism boosting foods.

And while we’re at it, metabolism boosting supplements which WORK! In this article, you’ll get a real comprehensive list you can use. I’ll go through everything you can do to boost your metabolism from metabolism boosting foods to supplements and much more!

l carnitine for bodybuilding beats this junk anyday! Many members ask me how to “burn more fat”; they even ask me for “diet pills” (OH HECK NO!) and wonder what is “wrong” with them. Most of them just need better metabolisms which is my inspiration to write about metabolism boosting foods and supplements here.

Well, first of all, we live in a society where portion control is a lost concept, and there is an abundance of fat and sugar everywhere.

So, the education starts with learning to eat more in a healthy way!  (Attribution: the great Dr.Weil.)

That means you need to check this blog and review all of the “how to eat” articles (including all the metabolism boosting foods and supplements).

Weight training is the fitness activity for metabolic boosting:

making more lean body massFirst of all, as you age, you lose muscle mass, so weight training is a MUST. As you get older, you are better off doing one set to “near failure” (you can’t do more reps) per muscle group; 2-3x per week.

You will get the results of about 80% of the 3-set routines but spend much less time in the gym. So, you’ll have a greater chance of sticking to your routine, and you’ll maintain your fat-burning muscle mass. Note there is no other way to gain rather than lose lean body mass.

To give you an idea of why this is so important, ponder this: at rest, a pound of fat burns 2 calories a day, while a pound of muscle burns around 50 calories a day. Furthermore, the increase in body temperature and thus “thermogenesis” or calorie burning is thought to last 4-5 hours after a strength workout whereas it’s only about an hour after a cardio workout. This is in addition to eating my healthy diet found on this website FREE (see end section) and adding metabolism boosting foods to the “mix.”

Now, you need to do near daily cardio for health and weight control. All good weight loss programs, led by mine, include this important component. This, combined with metabolism boosting foods provide a significant boost to your metabolic rate.

Check your thyroid function first:

Be sure your thyroid is functioning normally. Up to 1/3 of people with low thyroid are under or misdiagnosed. A sluggish thyroid will give you a sluggish metabolism. You want your doctor to check a Free T3, Free T4, RT3, and TSH. You want Free T3 and Free T4 to be upper 1/3 and RT3 at lower 1/3 of “normal values” you see on the lab slip. There are some who achieve these numbers and are still clinically hypothyroid so be sure your doctor is “informed.” Un-diagnosed hypothyroidism is a cause of unexplained weight gain and energy loss.

HGH and DHEA Hormones:

If you are over 30, your levels of Human Growth Hormone are waning. One way to boost them naturally is by taking one of our special amino acids in the evening. This will help keep up the muscle mass for both men and women for a while. Don’t forget that evening meal needs to contain-say it with me-metabolism boosting foods!

Another hormone which starts to go down around 30-35 is DHEA. Replacement with the keto form is “thermogenic,” and you will burn more calories. Both of these products are available in our store.


This wanes in men and women start losing it at about age 40. It is perfectly acceptable to replace to physiologic levels with bio-identical testosterone for both sexes. What is NOT acceptable is to “over-replace” to get that shredded professional bodybuilder look or “baseball pro look.”

This was slightly controversial for a while, but at this writing, it is not. In fact, a study just emerged showing the ill effects of anti-testosterone therapy for prostate cancer patients.

Metabolism boosting foods are healthy foods!

The pressure of losing weight can cause us to do crazy fad diets and even crazier diet pills. In return, this leaves your metabolism barely holding on leading to weight gain-an endless rollercoaster.

However, boosting your metabolism can be easy, if you know what foods you should eat and what supplements you should take.

Extra pounds can cause your metabolism to decrease due to the swap in the fat to muscle ratio. For women who want to lose weight during menopause, some of it has to do with amping up your metabolism to help with your weight loss.

Be careful, though, about amping up your metabolism during menopause. Why?

Too much of a good thing might throw off critical hormones, allowing for deposition of menopause belly fat and excess body fat due to increased cortisol from adrenal overstimulation. Read what you need prior to attempting this or just ask me! I know you are aware you want to increase muscle mass and decrease body fat, correct? That’s the goal here.

When you add to weight gain no physical activity, a true reversal of the fat to muscle ratio happens. As a result, it lowers your metabolism and makes weight loss harder. The solution for effective weight loss is to focus on healthy foods for weight loss, doing the “right” muscle building exercise and eating foods that speed up your metabolism. This includes giving a nutritional ketosis diet a try; it speeds up metabolism and suppresses hunger. (Link below).

These are metabolism boosting foods, and once you boost your metabolism, you can have a nice, steady pace of weight loss. Either way, choose healthy whole foods to lead the way. You know I keep talking about an anti-inflammatory diet plan so follow it! You can alternate this with my nutritional ketosis for weight loss plan for a bigger metabolic boost.

Foods you choose or say no to are the key

Metabolism has an impact on your body and how it processes and distributes nutrients within food to your organs. We use these nutrients as energy to help you keep your body moving and functioning, burn more calories, or for fat storage.

If your body is converting energy molecules efficiently, you start to burn calories rather than holding onto them. Conversely, if you do hold onto them, they are stored as fat. If you follow my website, along with my blogs, articles, and books, you will gain greater knowledge of how food can seriously influence your weight.

Today’s food market is full of “food-like” substances that sabotage your metabolism.

However, that is not all! Articles and popular weight loss franchises are providing misleading information on what they consider healthy.

Unfortunately, unless you are that lucky person born with a high metabolism, you must search for the healthiest foods. These include metabolism boosting foods and supplements to boost your metabolism too. It also wouldn’t hurt to add a natural appetite suppressant here and there.

All sorts of foods labeled as metabolism boosting have different mechanisms that are indirect or direct. In this article, I provide a thorough review of the best metabolism boosting foods along with supplements and tips. Within this content, I will provide the truth about the foods that are long known as metabolic boosters, but also note the ones that really are and the ones that have “indirect” effects.

Metabolism Boosting Foods: direct vs. indirect

Metabolism Boosting Foods with a Measurable Metabolic Kick

All types of hot peppers from around the world are first and foremost metabolism boosting foods. You can tell too-just eat and see how much your eyes water!

Other foods include salsa, wasabi, horseradish, ginger, garlic, mustard, vinegar, and cinnamon. These are all yummy metabolism boosting foods.

Over the years, more studies are showing that the chemical capsaicin found in several spicy metabolism boosting foods double an individual’s energy expenditure for several hours after eating. As a result, it eliminates up to 100 calories per day (according to a study by UCLA). Also, this magic substance is great for arthritis and will boost your immune system too! Mild peppers work just as well.

This likely applies to all the foods mentioned above. By just adding these ingredients to your meals you can boost your metabolism! Equally important, you can increase your endorphins! Note all the metabolism boosting foods above will kick up your metabolism and I’m calling them foods rather than spices. Why? Some people eat some of this stuff as if it is food. Ever see someone “go” through a plate of hot peppers? Impressive, isn’t it?


Water is an addition to your daily routine that is highly important, as not only can it provide a variety of benefits but it can help boost your metabolism. Not only does water act as a natural appetite suppressant that flushes out all of the toxins within your body, but it keeps you from mistaking thirst for hunger. The detoxification and aid in digestion help raise your metabolism when consuming water daily. Stay hydrated! Hydration is crucial as dehydration slows metabolism. Forget the 8 glass rule-it is usually double that or more; just watch the color of your urine which should be clear. (You all look-I know you do!)

Green Tea

Green tea is a popular metabolism booster, but for many good reasons. There is proof green tea boosts metabolism and even aids in weight loss, disease prevention, and helps improve mood naturally.

Green tea can also give a better (because you can have more of it) metabolic boost in decaf form with its antioxidant called EGC.

However, not just any green tea will do by the way.

You need to find a supplement or tea which contains the top 3% of the green tea leaves because that’s where the bioactivity for health and thermogenesis resides. You can take up to 1200 mg safely and be sure to find quality decaffeinated brands if you look elsewhere.


In coffee, dark chocolate, and black tea the caffeine creates a metabolism boosting effect. However, it is important to limit yourself with each of these items as a large dose can cause negative side effects.

Here I’m specifically referring to coffee and strong tea which, in large doses causes the adrenal glands to secrete toxic levels of cortisol and adrenaline.

Metabolism boosting foods which work Indirectly

It is important to review this part of the article as you may see all over the internet foods that are supposedly metabolism boosting. However, they do not directly impact your metabolism rate. Instead the process of eating (chewing), while not an appetite suppressant has an indirect effect on your metabolism. Although these types of foods have an indirect effect on your metabolism, they can help you lose weight. Below is a list of the foods that will accomplish this task. You can think of them as metabolism boosting foods, but remember they are not actually the real deal.

Fiber Rich Foods (whole grains, legumes, oats, fruits, and vegetables)

The first super vegetable to understand and benefit from is broccoli, as it is full of nutrients and vitamins like calcium, fiber, and vitamin C.

This superfood is calorie dense and can boost your immunity.

Along with broccoli, many other fruits and vegetables are high in fiber that can aid in suppressing cravings and improving satiety.

High fiber foods work indirectly by causing you to feel full faster and longer, therefore helping you lose weight in a natural way. Although it is not one of the direct metabolism boosting foods, it works.

Steel cut or rolled oats are always a favorite when it comes to a satisfying and healthy meal. It keeps you fuller longer and provides sustained energy. Oats also provide a healthy amount of fiber, minerals, and vitamins. Both of these are not metabolism boosting foods, even though other sources say they are.

Protein (Turkey, fish, etc…)


Metabolism boosting foods include those with high protein, as a safely increased amount of protein you consume, will increase your muscle mass.

Muscle burns about 50-73 more calories per day than fat during rest. Here’s a nod to high  bcaa foods and supplements as people who consume more branched chain aminos as in eggs, turkey, chicken, and supplements such as what we have here are leaner than those who do NOT.

Once your fat to muscle ratio improves, your metabolism will then increase as well. An easy way to add more protein to your diet is to ensure each meal has a clean source of protein such as free-range, organic, antibiotic free eggs, turkey or chicken. If you are Vegan, you can easily get creative with legumes. Another option, which is extremely popular and high in bcaa’s, is to introduce whey protein smoothies into your daily diet.

Energy Exhausting Foods (Apples, Celery, anything requiring a lot of chewing)

As you may be aware, some claim celery and apples to be metabolism boosting foods. They are not. They too have an indirect effect as individuals lose weight when they start to consume them rather than unhealthier snack choices.

The energy used to chew celery and apples burn more calories than absorbed. Although these do provide a boost in weight loss, this activity isn’t enough exercise (LOL) to boost your metabolism.

I suppose if you chewed celery all day the old wives tale of burning more than eat you would indeed be true. If you did this, your masseter muscles would be bigger too. Now, big enough for a metabolic boost? If so, barely measurable, yet we see claims “all over the place” that celery is one of the best foods that speed up metabolism.

 Products out on the market claiming to boost your metabolism:

Below I will review natural metabolism boosters that have proper studies and reports revealing they work. I will include my assessment of efficacy and safety of each.

There are too many claims regarding natural metabolism boosters that are not true!

Have you been a victim of false marketing? Perhaps, the claims about diet pills that require no effort to lose a great amount of weight appeal to you. Step right up and buy the scam! Extra weight will just melt away! DO NOT FALL FOR THIS! Weight loss is the #1 supplement scam!

These messages cause consumers to believe their advertisements are real; they will easily lose those unwanted pounds. But in the end, they are false and can impact your body in a very harmful way. Federal regulators have found dozens of these products containing hidden harmful ingredients that haven’t been studied in humans, therefore leaving you as a test dummy.

FDA gets off the market what are cytokines products which are NOTFood & Drug Administration Warnings

The FDA warns consumers of these dietary products, as they can be powerful drugs that claim to be “all-natural” or “herbal” supplements, but instead carry significant risks to unsuspecting users.

The FDA has even found some weight loss products containing the prescription drug ingredient called sibutramine.

Sibutramine was in an FDA-approved drug called Meridia, which was removed from the market in October 2010 because it caused heart problems and strokes.

However, that’s not all! The FDA has also found (and is still finding) other ingredients from prescription drugs that haven’t been approved or have been taken off the market. Several other weight loss products have also been contaminated with dangerous mixed ingredients. These include, but are not limited to, seizure medications, blood pressure medications, and other drugs not approved in the U.S. Many of these tainted products are imported and sold through the Internet, but sadly some of these can be found on store shelves. The FDA says it has made it a priority to seek out these dangerous products, stop them from being imported, and “will take legal action” against firms that manufacture and distribute them. I guess we’ll see.

Choosing Metabolism Boosting Supplements Wisely

Be careful about what you purchase and know that anything from AgeWell Solutions is safe.

It is now more important than ever to be cautious of any supplement before purchasing it.

Just because a store sells it does NOT mean it is either safe or effective. Although there are reports showing benefits for some dietary supplements, the claims of others may be unproven.

If something sounds too good to be true, it usually is.

Famous television doctors have been known to stretch the truth, even if it means an ingredient is ineffective. That is where I come in. I can provide real evidence and research to you-from a doctor. Note that every single product or ingredient I mention below is contraindicated (not recommended meaning don’t take it) if you are pregnant or nursing. I won’t keep repeating that.

Ingredients which claim to BURN FAT-by boosting metabolism-as stimulants:


how to tighten skin is with a coffee mask!

Description/Primary Functions

Caffeine is a natural stimulant that can boost your metabolism. It is usually found in coffee, caffeinated teas, and dark chocolate.

It aids in fat loss by boosting your basal metabolic rate, or BMR.

Several studies show a dose of caffeine increases subjects’ energy expenditures by 5 percent or more, helping their bodies burn calories and fat.

Caffeine stimulates metabolism. It can also enhance the effects of other fat-burning compounds like green tea and citrus Aurantium. Note caffeine in coffee, tea, colas, energy drinks are largely ineffective. It takes a higher of a dose of encapsulated caffeine to have a “good” effect-equivalent of 2-3 cups of coffee.

Caffeine is contraindicated in those hypersensitive to any component of a caffeine-containing product. Be cautious.

VERDICT for safety and efficacy as a way to speed up metabolism which will help you lose weight:

For caffeine to increase your metabolism, you will need more than one cup of coffee. However, if you give up all other sources of coffee and it doesn’t give you palpitations, then it’s OK. In my opinion, I am not a fan of it to aid in weight loss as a single ingredient because it usually causes the jitters and not a lot of metabolic boost unless combined with other ingredients. However, I’ll give it an OK-just don’t expect miracles. In reasonable and safe amounts, it won’t increase your blood pressure.


contains magselectDescription/Primary Functions:

Guarana is a climbing plant in the maple family native to the Amazon basin and especially common in Brazil.

Guarana is best known for its fruit, which is about the size of a coffee bean.

As a dietary supplement, guarana is an effective stimulant. Its seeds contain about twice the concentration of caffeine found in coffee beans. There’s some evidence that guarana–in combination with other supplements–may promote weight loss. It’s uncertain if guarana specifically was the main cause as caffeine is a stimulant that has been shown to improve mood and aid weight loss. Guarana may very well also have these effects.

Guarana is contraindicated in those hypersensitive to any component of a guarana-containing product. Guarana is not recommended for those with a seizure disorder, cardiovascular disease, liver failure, or with kidney failure. If you take Guarana, avoid products with excessive levels of caffeine, which can cause side effects, such as increased heart rate and blood pressure.

VERDICT for safety and efficacy as a way to speed up metabolism which will help you lose weight:

This will definitely work, but avoid any other source of caffeine as it WILL ratchet up your blood pressure. Another one I’m not crazy about, but again, in reasonable doses, it’s OK. You can combine it with decaf green tea-DECAF, please!

Citrus Aurantium/Synephrine/Bitter Orange

Description/Primary Functions:

Also known as bitter orange, this substance contains several alkaloids that stimulate the body’s beta-3 receptors to boost metabolism and increase fat burning. It also promotes the release of epinephrine and nor-epinephrine, which enhances mental energy and focus. After ephedra was taken off the market in 2004, bitter orange, a herb similar to ephedra, has been marketed as a weight loss aid. Proponents claim that bitter orange can stimulate the fat-burning process. The wrong brand of Bitter orange may raise blood pressure, increase heart rate or cause abnormal heart rhythms. (This just means you need to get a pure product with the correct dose-then unless you have a heart condition, you needn’t worry.) 


Bitter orange is contraindicated in those hypersensitive to any component of a bitter-orange-containing product. It should not be taken by those with a cardiovascular condition (such as heart disease or high blood pressure or diabetes). Bitter orange should not be combined with caffeine or any natural substances containing caffeine (such as caffeinated green tea, coffee, and high doses of yerba mate). It should also be avoided by anyone taking medications (such as MAO inhibitors) or herbs/supplements that increase heart rate. It is likely the most potent of all the supplements which are natural metabolism boosters, and it will provide a burst of energy. Be careful you don’t “overuse”. Our version metabogen, is very potent and has other ingredients to buffer the effects of the stimulants.

VERDICT for safety and efficacy as a way to speed up your metabolism:

It increases two substances-epinephrine and nor-epinephrine and even increases mental focus. Well, as with ephedra, which is not on the list because other than black market, it isn’t sold-this will also increase (bad for you!) cortisol levels if you do not use “the right product.” This gets the highest efficacy rating as a pharmaceutical grade product which is, of course, what we have here for you. I cannot vouch for other products you buy regarding safety and effectiveness. Take safety measures into account if you are not purchasing from my store.

Green Coffee Bean Extract 

if you need help falling asleep this is greatDescription/Primary Functions:
Coffee trees have beans that contain high levels of chlorogenic acid. Chlorogenic acid works in two ways.

First, it reduces the absorption of blood sugar (glucose) by the intestine. Then it inhibits an enzyme in the liver so that less glucose is released into the bloodstream.

With less glucose available, the body burns more fat stored in adipose tissues as a source of energy rather than glucose.

There is caffeine in all Green Coffee Extracts in varying amounts, unless decaffeinated.

Green coffee bean extract is contraindicated in those hypersensitive to any component of a green-coffee-bean-extract-containing product.

VERDICT for safety and efficacy as one of the ways to speed up metabolism to help you lose weight:

Research shows that if there is enough chlorogenic acid this does cause some degree of fat burning. If you take this, avoid other caffeine-containing products or use a decaf version.

Other  natural metabolism boosters which are not stimulants:


Description/Primary Functions:

Acetyl-L-Carnitine is in almost every cell of the body. It is derived from an amino acid and can improve the utilization of fat as an energy source. Therefore, l-carnitine can be beneficial in the treatment of a variety of conditions associated with impaired fat utilization and energy production. It’s been shown to help maintain and help to gain energy, increase muscle mass when combined with a good “glutamine enhancing ” program. Acetyl-L-carnitine is preferred by anti-aging doctors and researching in research studies because it is better absorbed from the small intestine than L-carnitine. (Also note that L-carnitine MIGHT be related to colon cancer whereas acetyl-l-carnitine is not.)


L-Carnitine is contraindicated in those hypersensitive to any component of a carnitine-containing product. Rare side effects include muscle weakness in uremic (renal failure) patients, and seizures may increase in those with seizure disorders.

VERDICT for safety and efficacy as one of the ways to speed up metabolism so you can more easily lose weight:

This supplement is healthy and great to use for decreasing glucose and triglycerides, as well as increasing brain health and protection. However, it doesn’t directly increase metabolism. Instead, it helps increase muscle mass and therefore increasing your metabolic rate- helping you lose weight. So, as much as I LOVE this supplement for the short term memory loss recovery effect, energy amping, and more it would be misleading if I told you this was a natural metabolism booster. No thumbs up or down here. With that in mind, DO know it is an indirect booster and has a ton of health benefits so on that count it’s really a thumbs up.

Garcinia Cambogia/HCA

works like pharmagabaDescription/Primary Functions:
HCA is the salt within dried fruit from Southeast Asia called brindal berry and Garcinia Cambogia. Research backs the effectiveness of HCA at reducing fat absorption, increasing fat metabolism, decreasing appetite, and lowering LDL cholesterol.

It has also been suggested that HCA inhibits the citrate lyase enzyme which is known to be an important catalyst in the metabolic process of converting excess carbohydrates into fat.

Once HCA inhibits this process, the body’s natural reaction is to increase carbohydrate oxidation which can result in sizeable weight loss.

HCA is contraindicated in those hypersensitive to any component of a HCA-containing product. Garcinia/HCA is possibly safe for most people when used for 12 weeks or less. Long-term safety is, however, unknown. It can cause nausea, digestive tract discomfort, and headache. 

VERDICT for safety and efficacy as one of the ways to speed up metabolism for weight loss:

This is a disputable result as it truly depends on the concentration of HCA and even then it’s still questionable. It is my feeling that the GI side effects are from products which are not pharmaceutical grade and contain contaminants. It doesn’t amp you up but remember long term safety is “unknown.” I’ll give this an OK, though. If you do consume this supplement, remember to test it for a short period and take breaks; sort through the list of other supplements during that time. We have a safe product, Metaboprime, that does everything you need to get your insulin, leptin, and ghrelin in balance “while you’re at it.” I’ll show you it at the end.


great example of healthy living at homeFucoxanthin is a type of antioxidant carotenoid (vitamin A relative) naturally occurring in edible brown seaweed such as wakame and hijiki, popular in Asian cuisine. Wakame is the seaweed in miso soup (a great healthy soup to implement into your diet).

Preliminary research has shown that when tested on animals it may target abdominal fat.

Fucoxanthin also doesn’t appear to be a stimulant like ephedra, bitter orange or caffeine.

Japanese researchers reveal fucoxanthin (isolated from wakame) promotes the loss of abdominal fat in obese mice and rats. Although we don’t fully understand how fucoxanthin works, it appears to target a protein, UCP1, that increases the rate at which abdominal fat burns.

Fucoxanthin is contraindicated in those hypersensitive to any component of a fucoxanthin-containing product. Seaweed is rich in iodine, and excessive consumption may result in iodine poisoning. High levels of iodine can interfere with the function of the thyroid gland. Always be cautious.

VERDICT for safety and efficacy as one of the ways to speed up metabolism  for weight loss:

As a single ingredient, there isn’t evidence that it works. However, it does indeed appear to enhance the “burn” of a well done bitter orange product.


one of the foods that reduce inflammationDescription/Primary Functions:
Capsaicin is a natural compound from chili peppers. Remember we talked about chili peppers as great metabolism boosting foods?

Well, capsaicin can be extracted from these chili peppers so you can guess the results. Capsaicin increases weight loss.

Proponents claim the compound can boost metabolism, and cause a shift in substrate oxidation from carbohydrate to fat oxidation.

A recent study suggests the ingestion of capsaicinoids can increase energy expenditure and fat oxidation through the activation of brown adipose tissue. Capsaicin can also decrease food intake and overall appetite, showing in a pivotal study to decrease ghrelin which promotes hunger.

Capsaicin is contraindicated in those hypersensitive to any component of a capsaicin-containing product. Although capsaicin is generally safe, it may cause some side-effects (such as stomach irritation and aggravation of ulcers and heartburn, as well as a possible interaction with certain medications (including aspirin and blood-thinning drugs).

VERDICT for safety and efficacy as one of the ways to speed up metabolism which will help you lose weight:

Although it may increase metabolic rate, it is important to be careful about many supplements and opt for getting this one naturally; it is an ingredient in natural metabolism boosting foods. Remember, all spicy foods, even the wasabi you get eating sushi is one of the great metabolism boosting foods. Capsaicin gets an O.K. from me if you are careful about the source.

Green Tea Extract

Description/Primary Functions:

Green tea offers many benefits, but the most popular one is how it aids in weight loss by speeding up metabolism and becoming an appetite suppressant. Green tea extract contains a catechin known as EGCG, which may slow carb absorption and increase fat burning by improving the function of insulin. Combine this with caffeine to increase metabolism much more than with caffeine alone.


Green tea is contraindicated in those hypersensitive to any component of a green-tea-containing product. While green tea is likely safe for most adults, drinking more than five cups a day may lead to caffeine-related side effects (such as headache, nervousness, sleep problems, and irregular heartbeat). The caffeine in green tea may also aggravate some health conditions, including anxiety, high blood pressure, and diabetes. Take precautions as always. You are 100% safe if you “go decaf” which ours’ is.

VERDICT for safety and efficacy as one of the ways to speed up metabolism for you:

It works. I would use decaf supplements and make sure they are pharmaceutical grade or else you don’t get enough active EGCG. You can combine this with any of the supplements I mention above as natural metabolism boosters.

Yerba Mate

an ingredient in moor spa productsDescription/Primary Functions:
Similar to green tea, Yerba Mate contains polyphenols and catechins. It can increase energy expenditure and aid in the loss of body fat by stimulating the body to use fat for energy. Yerba mate is a popular adaptogenic herb in South America and Europe.

Yerba mate is contraindicated in those hypersensitive to any component of a yerba-mate-containing product.

Some studies indicate people who drink large amounts of yerba mate over long periods may have a higher risk of some types of cancer, such as cancer of the mouth, esophagus, and lungs.

Smoking in combination with yerba mate seems to increase cancer risk significantly.

VERDICT for safety and efficacy as one of the ways you can speed up metabolism:

Since this is close to the green tea extract, it does work. You should not use this if you are a smoker-stop now- and no matter what don’t use this long term. Since it is about the same as green tea extract and green tea extract is good for your health, with no side effects, I would opt for that one instead.

7-Keto DHEA

Description/Primary Functions
7-keto-DHEA is a by-product of dehydroepiandrosterone (DHEA), a chemical that forms in the body. DHEA is a hormone produced by glands near the kidneys. But unlike DHEA, 7-keto-DHEA does not convert into steroid hormones such as androgen and estrogen. Taking 7-keto-DHEA by mouth or applying it to the skin does not increase the level of steroid hormones in the blood. 7-keto-DHEA increases metabolic rate and heat production to aid in weight loss. This is accomplished through the activation of three thermogenic enzymes. In keeping with the biological definition of thermogenesis, the three enzymes activation drive energy-producing substrates in a direction of less efficient ATP production relative to heat production. The enzymes also promote stored fat to be used for energy and heat production, enhancing thermogenesis.

7-Keto DHEA is contraindicated in those hypersensitive to any component of a 7-Keto-containing product.

VERDICT for safety and efficacy as a natural metabolism booster:

This supplement works. You can combine it with decaf green tea as well as with any of the products above. When taken alone, no health issues have been reported. If you have questions just ask me (free!) and I’ll give the best combo for YOU. Not only have no health problems been reported, but it also does many things that are good for your health including your immune system and brain.

SO, there you have it!

This is your guide to what truly works to increase your metabolic rate with naturally metabolism boosting foods, supplements, and more. With a proper exercise routine, nutrition, and supplements you can boost your metabolism naturally and effectively.

  1. Great information on metabolism. I recently went to my family doctor to have my thyroid checked. However, I was reviewing my labs and I don’t believe I was tested for everything you mentioned. I noticed that you offer consultations on labs. Would you be able to do this with the labs I just recently did?

FREE email consultation with Dr. Kim included with every purchase & FREE shipping on all orders over $150
