It depends on what you mean by "high protein." Some consider high protein diets as being 25-35 percent of their total calories. However, that is actually a pretty good balance for protein. Protein is an extremely important part of your diet as it helps you maintain muscle, reduce catabolism, and is thermogenic. In fact, for every 100 calories of protein, about 25-30 percent is burned just from digestion. This is more than twice the amount of carbohydrates and fats. However, protein needs to be eaten in balance with carbohydrates (i.e., vegetables, fruits, and starches) as well as dietary essential fats. If your goal is to lose body fat, I would suggest a macronutrient ratio of 30-40 percent protein, 20-30 percent carbohydrates, and 30-40 percent dietary fats. Make sure your carbohydrates come from most vegetable sources. Limit fruits to 1-2 servings per day. Have starchy carbs for after workouts only. Include essential fats (i.e., Omega 3 sources). You will see body fat melt off your body quickly. Oh! Also, eat only until about 80 percent full. Just don't do without any of the macros as they are all important to your body; each has their own important function.
