In one study, overweight and
obese adults who consumed 25 % of calories as fructose - sweetened beverages on a weight - maintenance diet
experienced reduced insulin sensitivity, increased belly fat and worsening of heart health markers (33).
The results of this study indicate that overweight or
obese adults who
experience a 5 % reduction in body weight over a four - year period obtain no psychological benefit and may be at risk of increased depression, despite benefiting from the expected reductions in cardio - metabolic risk.
