Philosophy Kiss meat goodbye. Cutdown on fats and simple carbs like sugar and alcohol.
How It Works At nine calories per gram, fat is more than twice as dense as protein and carbs. Thus dieters can consume the same amount of food but still lose weight if they eat less fat. Focusing on complex carbs like whole grains helps stabilize blood sugar, and lots of fiber increases satiety.
Downside Strictness. Giving up meat is hard, but no fatty nuts or avocados? Sheesh.
