Adherence

Dietary counseling interventions produce a modest net weight loss of approximately 2 BMI units (6%) at 12 months compared to usual care, but this benefit diminishes significantly over time as participants regain weight during the maintenance phase.

Dietary counseling helps you lose about 6% of your body weight in the first year, but you will likely regain much of it if you stop the active support. To keep the weight off, you need ongoing maintenance strategies, as the initial benefits fade over time.
