they should eat a lot more “natural” foods, such as fruit and vegetables, whole grains, nuts and yogurt, while avoiding anything processed.
Bigger daily portions of certain foods were linked to the largest weight gains over each four-year term. Crisps lead to a 1.69lb gain every term and sugar-sweetened drinks an additional 1lb.
But other foods gave less weight gain even when their consumption was increased.
Vegetables saw a loss of 0.22lb per four years, whole grains a loss of 0.37lb, fruits 0.49lb, nuts 0.57lb and yogurt 0.82lb.
Exercise reduced weight, while alcohol added it at the rate of 0.41lb.
