Dietary Intake, Anthropometric Measurements, and Blood Lipid Values in Weight Training Athletes (Body Builders)

Abstract

Dietary intake, plasma lipid levels, and anthropometric measurements were studied in 76 weight trained athletes (body builders) who had been following a consistent eating and training program for at least 2 years prior to the study. Dietary data were collected using the 7-day diet record. Nutrient analysis indicated that these athletes followed an atherogenic diet, characterized by a high-fat, high-cholesterol intake. The high-cholesterol intake was due to a high egg intake, which varied from 0 to 81 eggs per week. Although those athletes with a high egg intake consumed significantly more fat and cholesterol than those with a low egg intake, plasma total cholesterol levels (mean = 182.9 ± 25.7) did not differ over the range of egg intakes. Plasma HDL-cholesterol levels were higher and plasma triacylglycerol levels were lower at a high egg intake compared with that at a low egg intake. Plasma uric acid was not affected by the high animal protein intake. Despite the unfavorable intake of macronutrients, food alone supplied adequate amounts of micronutrients as compared with the RDA. Using different measurements of obesity, it was difficult to classify this group of athletes as overweight or obese, due to increased muscle development.
