Abstract
PURPOSE
To evaluate the effect of a low-calorie dietary approach to stop hypertension (DASH) compared to a low-calorie diet on weight control, body composition and glycemic measures in post sleeve patients with weight regain.
MATERIALS AND METHODS
Participants were randomly allocated to either the low-calorie DASH diet group (intervention) or the low-calorie diet group (control) for a duration of 16 weeks. Both groups had a prescribed caloric intake of 1000-1200 calories. The DASH diet group made dietary adjustments in accordance with the DASH pattern.
RESULTS
At the end of the study, both interventions significantly reduced anthropometric and body composition parameters (P-value < 0.001), with a greater decrease observed in the low-calorie DASH diet group (P-value < 0.001). Insulin levels and homeostatic model assessment for insulin resistance (HOMA-IR) decreased significantly in both groups, but the magnitude of these changes was not statistically different between the two groups. After adjusting for confounders, a significant difference was observed in post-intervention values and changes in weight, body mass index, and fat mass and fat-free mass.
CONCLUSION
In summary, adhering to a calorie-restricted DASH diet for 16 weeks improved weight loss, body mass index, and fat mass reduction in post-bariatric patients who experienced weight regain 2 years after surgery, compared to a calorie-restricted control diet. However, there was no significant difference in the effect on blood glucose, insulin, and HOMA-IR between the two diets.
