4. Avocado and Other Healthy Fats
Just because a food has plenty of fat and calories in it doesn’t mean it ‘s “fattening.” See, certain foods cause you to gain weight because they provoke hormonal changes that trigger cravings, or “rebound hunger.” One hunger-control hormone, leptin, becomes blunted by starchy, sweet, fatty, and refined-carbohydrate foods. That’s why a bagel is fattening: It’s a high-caloric load of refined carbohydrates that double-crosses your natural satisfaction response.
Avocados on the other hand aren’t fattening, because they ‘re loaded with healthy fat and fiber and don’t cause wild swings in insulin levels. So enjoy the fat in avocados, olive oil, and nuts. Research shows that diets containing upward of 50 percent fat are just as effective for weight loss as those that are low in fat.
