Research suggests high Ca or dairy intake contributes to greater weight and fat loss; this remains controversial. We examined the role of dairy food in a moderate energy restricted diet to enhance central fat and weight (WT) loss in overweight and obese adults, whose dairy consumption was ≤1 serving/d & ≤ 600 mg of dietary Ca/d. Overweight and obese (BMI = 27.4–37.5 kg/m 2 ) men (n=20) and women (n=51) were randomly assigned to a high dairy (HD: 3–4 servings/d = 1369mg Ca/d) or low dairy (LD: ≤ 1 serving/d = 481mg Ca/d) 12 wk controlled diet. Energy balance was achieved in wks 1–3 followed by 12wk of 500 kcal/d reduction. All food was supplied by the metabolic kitchen. WT, body fat (BF) by DXA, and intra‐abdominal adipose tissue (IAAT) by CT‐scan were measured pre‐ and post‐intervention. GLM analysis adjusted for initial WT, BF and IAAT showed no significant difference in percent change of WT (p = 0.94), BF (p = 0.68) or IAAT (p = 0.41) by treatment.Treatment Δ Weight, kg Δ Body Fat, kg Δ Intra‐abdominal Adipose Tissue, ccHD −6.20 ± 2.9 −5.19 ± 2.7 −8.0 ± 6.9 LD −6.04 ± 3.2 −5.36 ± 3.0 −10.26 ± 9.73An energy restricted diet with 3–4 servings of dairy does not enhance central fat or weight loss over energy restriction alone.
