Energy balance

Increasing daily servings of potato chips, potatoes, sugar-sweetened beverages, unprocessed red meats, and processed meats is independently associated with greater long-term weight gain, whereas increasing servings of vegetables, whole grains, fruits, nuts, and yogurt is associated with less weight gain.

To prevent long-term weight gain, focus on specific food swaps rather than just counting calories. Reduce daily servings of potato chips, french fries, sugar-sweetened beverages, and processed meats. Instead, increase your intake of yogurt, nuts, fruits, whole grains, and vegetables. These changes are independently associated with less weight gain, likely because they are more satiating and displace less healthy options.

On the basis of increased daily servings of individual dietary components, 4-year weight change was most strongly associated with the intake of potato chips (1.69 lb), potatoes (1.28 lb), sugar-sweetened beverages (1.00 lb), unprocessed red meats (0.95 lb), and processed meats (0.93 lb) and was inversely associated with the intake of vegetables (−0.22 lb), whole grains (−0.37 lb), fruits (−0.49 lb), nuts (−0.57 lb), and yogurt (−0.82 lb)
