There are 2 mechanisms by which increased dietary protein intakes can promote a negative energy balance and loss of body fat. The first is the ability of dietary protein to increase energy expenditure. A more important mechanism by which dietary protein promotes weight loss appears to be its ability to produce greater satiety than do other macronutrients.
One study placed participants on a high-protein diet consisting of 20% fat, 50% carbohydrate, and 30% protein. With greater satiety by the high protein diet, the subjects ate about 450 fewer calories per day and lost about 1 lb per week (11 lbs in 12 weeks). Experts advise consuming about 0.5 grams of protein per pound of your body weight. That's 70 grams for a 140-pound woman. Try to keep the maximum amount of protein to 30 g per meal and 20 g per snack. The body can only absorb and utilize about 30-40 g at one time...any excess will be wasted.
Here are some protein smoothie options to start your day, that will keep the hunger down and under 400 calories.
