Metabolism boosters figure in many diet supplements to enhance the natural ability
of the human body to burn the food calories that we ingest everyday. Metabolism is
basically the physiological process of breaking down the complex molecules like fats,
carbs and proteins that we ingest in our meals.
These get converted to the energy reserve we need to fuel everything we do. Children
have the fastest metablic rates and start to slow down as we age. As a result, people
tend to store more of what they eat, instead of getting them metabolized, so they
Metabolism boosters, as the name suggest, artificially improve or increase the metabolic
rates to convert carbs and fats we eat or store into heat or energy which make us
How Do Metabolism Boosters Work For Weight Loss?
Clinical studies in lab rats have shown that there are certain minerals, polyphenolic
(antioxidants) compounds and amino acids that can increase metabolic functions at
the cellular and tissue level to help your body’s metabolism more effectively.
Diet supplements claiming to be natural metabolism boosters contain green tea, dietary
fibers, animal thyroid and proteins. There have been some lab studies that point
to the efficacy of certain compounds to boost the mitochondrial function of cells
in lab rats to metabolize fat into energy at the cellular level such as Resveratrol.
The action involves the creation of Sirtuin enzymes that boost metabolic rates. Unfortunately
there are still no clinical trials on human subjects to independently confirm similar
results at the level of dosage that can be considered beneficial and safe.
Are Metabolism Boosters Good?
Most dieticians and bodybuilders share the opinion that physical activity as simple
as walking everyday have more positive effects on your metabolism than most over-the-counter
metabolism boosting food supplements.
If they do, the increase is generally marginal at best and only a lifestyle change
has been observed to create dramatic impact on a person’s metabolism.
Here’s a sample of what some dieticians say about these products:
From Jeremy, New York:
“I wish I could say they’re effective, but in all my years as a gym instructor with
a degree in pharmaceutics, I have to say nothing beats a good exercise program in
boosting your metabolism.”
From Cheryl, Washington:
“Many dieters who take these supplements undergo gym workouts and you can’t tell
for sure if their weight loss was due to those metabolism enhancers or the exercises
they do. Until you take them off from either. Then you realize the exercise is
doing it all. And getting out of the exercise routine gets you back to your overweight
condition even as you continue taking these supplements.”
Are Metabolism Boosters Safe?
Metabolism boosters using animal thyroid ingredients have been reported to elicit
some nasty side effects like excessive sweating, nervousness, diarrhea and palpitations
to mention some.
On the other hand, metabolism boosters formulated from botanical extracts have none
of these side effects but have considerably less efficacies. To be safe, consult
with your doctor before using any, especially if you have a history of allergies,
suffer from heart disease, hypertension or other medical condition, or are taking
prescription drugs that could cause complications.
