Protein, Not Deprivation

A higher protein diet doesn't have to be carb free to help you lose weight.
Severely restricting carbohydrates is not the reason some people
experience weight loss with a high-protein diet. It's the protein that
sates their appetite and helps them lose weight. In a study, people
who ate just a bit more protein each day, while eating less fat and an
average amount of carbs, felt sated earlier, ate fewer calories, and
still lost weight.

Some high-protein diets ask people to eat three times as much protein
as they do carbohydrates and limit their carbs to as little as 50
grams per day or less. Severely limiting carbohydrate intake and
getting most of your calories from protein can be unhealthy for
several reasons. First, many healthful foods are high in carbohydrate,
including whole grains, legumes, fruits, and vegetables. A diet that
severely restricts carbs will lack these nutritious foods. Second, a
diet that is extremely high in protein can cause ketoacidosis, a
condition in which the body's blood is highly acidic and the body's
equilibrium can become extremely unstable. For optimum health and
weight loss, eat a healthy, well-balanced diet consisting of foods
from all major food groups. In a recent study, researchers compared
the effects of diets containing different amounts of calories from
protein, fat, and carbohydrates. When participants followed a
calorie-controlled diet consisting of 30 percent of calories from
protein, 20 percent from fat, and 50 percent from carbohydrates, they
felt much more satiated than when they consumed a diet with less
protein, more fat, and the same amount of carbohydrates. Later, when
they were allowed to consume as many calories as they wanted as long
as they stuck to the 30:20:50 ratio, participants consumed about 450
fewer calories per day and lost almost 11 pounds.
