Energy balance
Higher habitual fruit intake is inversely associated with weight change (decrease) and waist circumference, whereas vegetable intake alone shows no significant association with weight change.
To support weight management, prioritize increasing your daily fruit intake. For every 100 grams of fruit you add to your diet, you can expect a small reduction in annual weight gain (approx. 14g). While vegetables alone did not show a significant weight effect in this analysis, high fruit intake is linked to reduced waist circumference and a lower risk of developing obesity.
Higher intake of fruits was inversely associated with weight change (decrease) (beta-coefficient per 100-g increment, -13.68 g/year; 95% CI, -22.97 to -4.40). No significant changes could be observed for combined fruit and vegetable consumption or vegetable consumption. Increased intake of fruits was inversely associated with changes (decrease) in waist circumference (beta: -0.04 cm/year; 95% CI, -0.05 to -0.02).
Why this rating
Meta-analysis of prospective cohort studies (observational), not RCTs, with high heterogeneity (I2 > 90% for some metrics).
