Can a magical little pill instantly and effortlessly melt away those extra pounds?

It seems like every time we turn on the TV or open a magazine, there is a new “all-natural” way to boost our metabolisms and shed the pounds without lifting a finger.

To understand how metabolism boosters work, it is important to know exactly what your metabolism does.


Everyone has a basal metabolic rate (BMR), which is the minimum amount of calories, or energy, that we need for our body to function each day. Since exercise requires the body to burn more calories, active people have a higher metabolic rate than those who are sedentary. Weight loss supplements, or “metabolism boosters,” supposedly promote an increase in the calories the body will burn and the breakdown and excretion of fat, thereby reducing fat accumulation in the body and improve the feeling of fullness after eating (which helps you ingest fewer calories).


Naturopathic doctor Natasha Klemm believes that metabolism boosters can be helpful in conjunction with a healthy diet and regular exercise. “High-quality and well-researched weight loss supplements can be a helpful addition to any weight loss program for individuals 18 years and older by enhancing caloric metabolism and blood sugar regulation. Weight loss supplements should not be solely relied on, as there can be adverse side-effects with increased consumption and use.”

Keep your expectations realistic when using metabolism-boosting supplements. We break down some of the more popular products you may have heard of:

1. Green tea extract

High in antioxidants, green tea extract has been marketed as a weight loss aid as of late. Klemm says that in recent studies, green tea combined with caffeine helped participants lose weight and see a reduction in hip and waist measurements. “Green tea extract and caffeine show promise as a weight loss supplement when combined with a healthy diet and exercise.”

2. Raspberry ketones

Made popular by Dr. Oz, raspberry ketone is the compound in the berry that gives raspberries their scent. It should be noted that there has yet to be any studies that show the effectiveness of this supplement for weight loss in humans. Klemm notes that in studies with mice, “the ketones appear to increase the breakdown of fat after a meal, preventing accumulation in the body.” More research is required to substantiate any claims made for weight loss in humans.

3. Apple cider vinegar

A common weight loss aid from the 70’s, apple cider vinegar is making a comeback, but there are no scientific claims that it helps with metabolism. If taken before a meal, apple cider vinegar promotes protein digestion. “This optimizes absorption of amino acids that are required for muscle building and hormone production, which can positively affect metabolism and weight,” says Klemm.

If you are considering adding supplements to your weight loss plan caution should be taken. Always consult a health care provider before starting any weight loss regimen.
