Controversy exists in literatures concerning the effect of diet-alone or diet-with exercise in altering blood high-density lipoprotein-Cholesterol (HDL-C) concentration. This case study has assessed the influence of consuming high-CHO and high-fat diet in altering blood HDL-C alone or in combination with exercise. A healthy active subject, 29 years and 78 kg had a basal HDL-C level of 50.9 mg/dl with normal-balanced diet. 1. During diet-alone trial, the subject consumed a high-CHO diet (70% CHO, 18% fat, 12% protein) for 1-month and his HDL-C level was 36.3 mg/dl. After 7-days gap, he took high-fat diet (20% CHO, 68% fat, 12% protein) for 1-month and his HDL-C was raised to 71.4 mg/dl. 2. During diet with exercise trial, the subject took similar (i.e., high-CHO and high fat) diet and additionally performed an intensive (85% HRmax, 30 min), and moderate excise (50% HRmax, 90 min) tests with 7 days interval. Results indicated that high-CHO intake alone or with exercise, depressed blood HDL-C to the same degree (by about 28%), but to the contrary, intake of high-fat diet elevated HDL-C (by about 40%) compared to the basal diet. Exercise did not influence HDL-C concentration different from the dietary effect alone. This case report primarily indicates a greater sensitivity of HDL-C to diet than physical exercise in optimizing blood HDL-level. A cohort study that includes gender is necessary to reach to a reasonable conclusion.
