Adherence
Psychosocial factors (confidence, social support, emotional eating) and metabolic status are stronger predictors of weight loss success in behavioral obesity treatment than diet type (low-fat vs. low-carb) or demographic variables alone.
If you are starting a weight loss program, your success is less about whether you choose low-fat or low-carb and more about your mindset and environment. Assess your confidence in sticking to the plan, manage emotional eating, and ensure your social circle is supportive. If you struggle with emotional eating, seek specific psychological support alongside dietary changes.
Diet type was not a key factor. Among racial/ethnic minority participants, the best predictors of weight loss were lower levels of emotional eating, less friend discouragement, and presence of metabolic syndrome. Among non-Hispanic White participants, the best predictors were high confidence in participating fully in the intervention, more family encouragement, and lower outcome expectations.
Why this rating
Derived from a large, well-conducted RCT (DIETFITS) with a robust secondary analysis using signal detection on 436 participants, though the analysis is exploratory/hypothesis-generating.
