Adherence

Long-term weight loss maintenance is associated with consuming a diet with limited variety across all food groups, particularly high-fat-dense groups, which helps sustain lower energy intake.

To maintain weight loss, consider limiting the variety of foods you eat, especially high-fat items. Successful maintainers often eat a narrower range of foods, which simplifies their diet and helps control energy intake. Focus on variety within low-fat groups (like vegetables) but restrict variety in high-fat groups (like sweets and fried foods).

ModerateSupportsMEDIUM confidence
These results suggest that successful weight loss maintainers consume a diet with limited variety in all food groups. Restricting variety within all food groups may help with consuming a low-energy diet and maintaining long-term weight loss.
