This study presents the diet and exercise strategies of a world-class bodybuilder during an 8-week precompetition period. Weighed food records were kept daily, and body fat, resting metabolic rate (RMR), ${\text{VO}}_2\max$, blood lipids, and liver enzymes were measured. Two hrs of aerobic exercise and 3 hrs of weight training were done daily 6 daystweek. Mean energy intake was 4,952 kcallday (54 kcallkg) and included 1,278 kcallday from mediumchain triglycerides (MCT). Diet without MCT provided 76% of energy from carbohydrate, 19% from protein (1.9 g proteiag), and 5% from fat. Micronutrients were consumed at ≥ 100% of the RDA, except for zinc and calcium, without supplementation. Mean RMR was 2,098 kcallday and represented 43% of energy intake. ${\text{VO}}_2\max$ was 53 ml.kg⁻¹.min⁻¹. Underwater weighing showed that body fat decreased from 9% to 7%. Blood lipids were normal, but two liver enzymes were elevated (alanine and aspartate aminotransferase). This world-class bodybuilder achieved body fat goals by following a nutrient dense, high energy, high carbohydrate diet and an exercise program that emphasized both aerobic and anaerobic metabolism.
