      moderate-protein moderate-fat diet during weight loss in male weightlifters: a 
      pilot study.

AB  - PURPOSE: Athletes risk performance and muscle loss when dieting. Strategies to 
      prevent losses are unclear. This study examined the effects of two diets on 
      anthropometrics, strength, and stress in athletes. METHODS: This double-blind 
      crossover pilot study began with 14 resistance-trained males (20-43 yr) and 
      incurred one dropout. Participants followed carbohydrate-matched, high-protein 
      low-fat (HPLF) or moderate-protein moderate-fat (MPMF) diets of 60% habitual 
      calories for 2 weeks. Protein intakes were 2.8g/kg and 1.6g/kg and mean fat 
      intakes were 15.4% and 36.5% of calories, respectively. Isometric midthigh pull 
      (IMTP) and anthropometrics were measured at baseline and completion. The Daily 
      Analysis of Life Demands of Athletes (DALDA) and Profile of Mood States (POMS) 
      were completed daily. Outcomes were presented statistically as probability of 
      clinical benefit, triviality, or harm with effect sizes (ES) and qualitative 
      assessments. RESULTS: Differences of effect between diets on IMTP and 
      anthropometrics were likely or almost certainly trivial, respectively. Worse than 
      normal scores on DALDA part A, part B and the part A "diet" item were likely more 
      harmful (ES 0.32, 0.4 and 0.65, respectively) during MPMF than HPLF. The POMS 
      fatigue score was likely more harmful (ES 0.37) and the POMS total mood 
      disturbance score (TMDS) was possibly more harmful (ES 0.29) during MPMF than 
      HPLF. CONCLUSIONS: For the 2 weeks observed, strength and anthropometric 
      differences were minimal while stress, fatigue, and diet-dissatisfaction were 
      higher during MPMF. A HPLF diet during short-term weight loss may be more 
      effective at mitigating mood disturbance, fatigue, diet dissatisfaction, and 
      stress than a MPMF diet.
