Milk May Help In Weight Loss

Drinking milk may prevent obesity. Scientists found a natural ingredient in milk that have similar effects as resveratrol. Maybe it'll become the next metabolism-boosting supplement.

"The researchers identified this ingredient, known as nicotinamide riboside, as they were searching for alternative ways to boost the well-known gene SIRT1, which comes with benefits for both metabolism and longevity."

"Mice that took nicotinamide riboside in fairly high doses along with their high-fat meals burned more fat and were protected from obesity while keeping them fit and energetic. They also became better runners thanks to muscles that have greater endurance."

The question is that how much of nicotinamide riboside you need to see the effect?
