The results of the largest study on contributors to weight gain are in: Eating fewer calories is a less effective weight control strategy than eating more good foods and fewer bad foods. And everyone can use a little weight control. The average person is likely to gain 3.3 pounds every 4 years.
Bad foods (Foods whose increased consumption contributed to the greatest 4-year weight gain):
- French fries (3.4 pounds)
- Potato chips (1.7 pounds)
- Sugar-sweetened drinks (1 pound)
- Red meats and processed meats (0.95 and 0.93 pound, respectively)
- Other forms of potatoes (0.57 pound)
- Sweets and desserts (0.41 pound)
- Refined grains (0.39 pound)
- Other fried foods (0.32 pound)
- 100-percent fruit juice (0.31 pound)
- Butter (0.3 pound)
Sugars and fiberless starches (refined grains) slow down metabolism. Whole grains don't.
Good foods (Foods whose increased consumption resulted in weight loss or no gain per 4 years)
- Vegetables - Those who lost weight ate 3.1 more servings of veggies per day than those who gained the most weight
- Fruits
- Whole grains
- Dairy - Regardless of whether it's low or full fat milk or cheese, had a neutral effect on weight gain
- Nuts and peanut butter - Despite conventional advice to eat less fat, weight loss was greatest among people who ate more yogurt and nuts, including peanut butter, probably because they slow the return of hunger.
- Yogurt - The food most strongly linked to weight loss which is the study's most surprising dietary finding. Those who ate more yogurt lost an average of .82 pounds per 4 years. Yogurt contains bacteria that increase intestinal hormones that make you feel fuller and less hungry and may also raise your metabolism.
