Many people are secretly hoping for a breakthrough discovery  of a pill they can take that will replace the need to exercise and eat a  healthy diet.
While that isn't likely to happen, some supplements can  provide some — but not all — of the benefits of exercise and the right type of  diet.
In the past, I’ve told you about how vitamin C can have some  of the same beneficial effects on your body as exercise. But what about diet?
Turns out, there’s another nutrient that may give your body  what it needs to shed a few pounds.
According to research published in the journal Cell  Metabolism, there may be a way to mimic some of the advantages of calorie  restriction without changing your eating habits at all.
Previous research has shown that resveratrol improves energy  metabolism and mitochondrial function in animals. So researchers decided to  test it in 11 obese men in a randomized, double-blind, 30-day crossover study.
The researchers found that the men who received 150 mg of  resveratrol a day experienced significant reductions in their sleeping and  resting metabolic rates and improved their mitochondrial respiration.
The resveratrol also had several positive effects on lipid  levels, circulating glucose, triglycerides, alanine-aminotransferase, and  inflammation. The participants’ systolic blood pressure went down, and so did  their adipose tissue lipolysis and plasma fatty acid and glycerol levels.
What's interesting is that these metabolic improvements  mimic those typically seen with calorie restriction. However, the participants  didn't make any changes to their diets. All they did was take resveratrol.
However, these results don't mean you can just take a  supplement and your health problems will disappear, particularly if you're  dealing with obesity. If you continue to overeat, you will continue to gain  weight, no matter how many supplements you take. It's important to make sure  you're eating an appropriate amount for optimal health.
Still, you can complement the effects of a good diet by  taking resveratrol, which you can find online and at any health food store.  It's a great way to supercharge your efforts to take control of your metabolic  health.
