Energy balance

High intake of dietary fiber, particularly from whole grains, is associated with lower central adiposity, reduced weight gain, and improved insulin sensitivity.

Increase your intake of dietary fiber, specifically from whole grains, vegetables, fruits, and legumes. Aim for high-fiber whole foods rather than supplements. This helps control weight gain, reduces central adiposity (waist circumference), and improves insulin sensitivity.

GoodSupportsHIGH confidence
Several components of the MedDiet have been inversely associated with BMI or waist circumference. This is the case for whole grain and fibre... high fibre intake is associated with a lower increase in body weight or central adiposity.
