Abstract

Weight Lifters often manipulate dietary protein to build muscles, and one dietary approach is a High-Protein Ketogenic Diet (HPKD). However, very little research has been conducted on the effects of a high-protein ketogenic diet on strength training performance and muscle building outcome goals. Therefore, the purpose of the present study is to investigate whether a high-protein ketogenic diet (HPKD) is an effective strategy to decrease fat mass (FM), and maintain lean body mass (LBM) without compromising strength training performance in recreational, weight lifters. In a parallel-arm, longitudinal, diet- and exercise-controlled design, 43 participants (mean ± SD age = 24.58 ± 9.26 years) exercised for 6 weeks while consuming either a high-protein ketogenic diet (HPKD) or a Normal Diet (ND). The HPKD intervention group (males, n = 13; females, n = 11) was instructed to consume a diet with 60% fat, 35% protein and 5% carbohydrates. Those in ND group (males, n = 10; females, n = 9) maintained a normal diet with 25% fat, 15% protein and 60% carbohydrates. The HPKD group significantly decreased body weight (mean ± SD, Weight: -1.55 ± 2.38 kg, p < 0.05), body fat percent (mean ± SD, %BF: -3.58 ± 0.85 kg, p < 0.05), and fat mass (mean ± SD, FM: -2.80 ± 0.87 kg, p < 0.05) compared to pre intervention measurements while significantly increased lean mass (mean± SD, LM: 1.25 ± 2.02 kg, p < 0.05), basal metabolic rate (mean ± SD, BMR: 76.76 ± 2.02 kcal/d, BMR: +4.44%, p < 0.000001), and strength (1RM) for all three lifts (bench press: 8.13 ± 4.85 kg, p < 0.05; back squat: 5.0 ± 2.95 kg, p < 0.05; deadlift: 8.13±7.04 kg, p < 0.05) between pre and post intervention in 6 weeks. However, there were no significant differences were observed (p > 0.05) in any variables of the HPKD group compared to ND group (Weight: p = 0.52, Body Fat Percentage: p = 0.62, Fat Mass: p = 0.58, Lean Mass: p = 0.63, BMR: p = 0.47, Back Squat: p = 0.29; Deadlift: p = 0.15; Bench Press: p = 0.18). Our data show that adhering to a HPKD combined with Strength Training for 6 weeks can lead to significant decreases in %BF, FM, and body weight, while significantly improving LM, BMR and overall strength performance in all three main lifts. This indicates a high-protein ketogenic diet can be an effective strategy to reduce body weight and fat mass without negatively affecting lean body mass, strength, or power performance.
