Still, some people may be so focused on losing weight that they end up losing too much, including muscle mass. Unfortunately, this is inevitable, Dr. Grunvald said. "Any time you lose weight, you're going to lose approximately a quarter to a third in body mass, so you can't get around [losing muscle]," he explained. To minimize this, he recommends resistance training throughout the weight-loss process and eating adequate amounts of protein, about 15 percent of your daily calories.
Protein is a fundamental part of a healthy and balanced diet, but when you are in the daily grind, you may not get the proper amounts, especially if your goal is weight loss. Protein not only helps keep you satisfied for longer, it also contains amino acids like leucine, which has been shown in research to aid in maintaining muscle during weight loss. <<<
