Mediterranean-Style Diet Matches Calorie Restriction for 3.4-3.5% Weight Loss at 24 Months but Raises Diet Quality Scores
Two-year RCT shows Mediterranean-style and calorie-focused programs yield equivalent modest weight loss yet divergent diet-quality gains. Evidence indicates adherence and nutrient density jointly matter for sustained cardiometabolic benefit. Larger, longer trials with pre-specified quality endpoints are required.
Limitations include secondary analysis of diet quality, single-region sample, and 24-month horizon. Next-step trials should pre-specify diet-quality endpoints, extend follow-up to five years, and test scalable Med-South adaptations against other high-quality patterns such as DASH or Nordic diets.
Gardner: In a 5-year follow-up of similar trials, sustained adherence in Med-style arms will exceed calorie-focused arms by at least 15 percentage points.
