High Protein / Low Carb?

No. Not good. You might as well throw the protein in the garbage. For each gram of protein to be used by your body, it needs 4 grams of carbos. When your protein is high, it is only filling your stomach, but not being used by your body (so its not fueling muscles/muscle growth without the carbs present). It stresses your digestive system (but you may not feel it) and other organs. A balanced low-fat diet with real food and a variety of exercise (cardio and strength) is the way to go. "They" say 30% calories from fat, but from many health experts, that is too high. Use this site, set your weight loss goal (1 to 1.5 pounds lost per week is safe and managable without stressing out) and you will get there. It will take longer than your friends method, but you will be at your goal when she is still pounding the weights eating a rigid diet and you'll be used to a healthy diet, fun exercise, and enjoying your accomplishment. Think of this, the extra weight that you want to lose--how long did it take to put on? It may take that long to burn it off. Don't expect overnight success, but demand success in the end. GOOD LUCK!
