Abstract

Background: Obesity is a worldwide health problem with increasing prevalence. Decrease in energy intake has been shown to lower the risk of coronary artery disease in obese subjects. The common form of dietary restriction is daily calorie restriction (CR). Another form is alternate-day fasting (ADF). This study examined the ability of modified ADF to facilitate weight loss and lower cardiovascular risk factors in overweight and obese women.

Methods: 15 adult subjects completed an 8 weeks trial (2 weeks observed and 6 weeks ADF). All women consumed very low calorie diet on the fast day and usually diet in every other day. Body weight (BW), fat mass and blood pressure (BP) were measured. Fasting blood samples were collected at the first and 57th day of trial for biochemical analysis.

Results: During the course of the trial, BW of the subjects decreased (p < 0/0001) from 84/3 ± 11/44 kg to 78/3 ± 10/18 kg. Waist Circumference decreased from 87/87 ± 9/74 to 82/86 ± 9/68(p < 0/001). Reduction in systolic BP was seen from 114.8 ± 9.16 to 105.13 ± 10.19 mmHg (p < 0/001) and diastolic BP changed from 82.86 ± 10.6 to 74.5 ± 10.8 (P < 0.05). Total cholesterol decreased from 227/73 ± 49/96 to 214/67 ± 43/27, TG from 160/5 ± 46/18 to 143/9 ± 22/77, LDL from 149/46 ± 49/81 to 131/3 ± 50/97, and FBS from 102 ± 14/7 to 96 ± 11/79 mg/dl but were not significant. HDL increased from 42/32 ± 18/01 to 50/58 ± 19/46 and was not significant.

Conclusion: These finding suggest that short time ADF is a viable dietary option to help obese individuals lose weight and decrease some CAD risk factors. More and longer-term studies in human subjects are needed to support this important result.
