Even though artificially sweetened drinks are calorie-free, drinking too many can actually hinder your fat-loss progress. It seems that beverages like diet soda mess with your brain’s ability to regulate calorie intake, causing you to feel hungrier than normal so you eat more total calories. Other research suggests that the sweet taste of these drinks can increase the release of insulin, which can blunt fat-burning and enhance fat storage.
There’s a reason everyone harps on about protein: Not only does it help keep you full, but it’s also responsible for repairing the tiny tears caused by strength training in your muscles. This helps them grow bigger and stronger, nudging out body fat in the process. As a general rule of thumb, aim to get at least 70 grams of protein throughout the day, says Dr. Cheskin.
