"Good, clean sources of protein are key to weight loss," says Mary Gocke, RDN, CDN, director of nutrition at the Blum Center for Health in Rye Brook, NY. And while red meat gets a bad rap, there is a way for it to be a healthy choice. Ott recommends choosing high-quality, leaner cuts, such as top sirloin, and eating small portions in moderation—say, two to three ounces two to three times per week. (While there's no agreed-upon guideline for red meat consumption, the American Cancer Society suggests eating fewer than 18 ounces, or about six small servings, a week.) "Protein is by far the most filling nutrient,” says Ott. “Eating a high-protein diet can help you burn more calories, because it takes more calories to break down protein than any other nutrient."
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
