摘要

Background High-fibre and low-carbohydrate diets may enhance satiety and promote weight loss. We compared a diet rich in beans aiming to increase dietary fibre and promote weight loss with a low-carbohydrate diet in a randomised controlled trial to assess effect and tolerability of the high-fibre bean-rich diet. Methods and results One hundred and seventy-three women and men, with a mean body mass index of approximately 36?kg?m?2 (one-fifth with diabetes type 2) were randomised to a high-fibre bean-rich diet that achieved mean (SD) fibre intakes of 35.5 (18.6)?g?day?1 for women and 42.5 (30.3)?g?day?1 for men, or a low-carbohydrate diet. Both diets were induced gradually over 4?weeks and included a 3-day feeding phase. Among 123 (71.1%) completers at 16?weeks, mean (SD) weight loss was 4.1 (4.0)?kg in the high-fibre versus 5.2 (4.5) kg in the low-carbohydrate group [difference, 1.1?kg, 95% confidence interval (CI)?=??2.6 to ?0.5; P?=?0.2], with results similar to the intent-to-treat population. Low-density lipoprotein (LDL)-cholesterol levels decreased with the high-fibre diet (difference in LDL-cholesterol versus low-carbohydrate diet, 0.2?mmol?L?1, 95% CI?=?0.01–0.44?mmol?L?1; P?=?0.045), as did total cholesterol (P?=?0.038), whereas changes in other lipids and glucose did not differ. After 52?weeks, the low-carbohydrate (n?=?24) group tended to retain weight loss better than the high-fibre group (P?=?0.06), although total cholesterol remained lower with the bean-rich diet (P?=?0.049). Conclusions A high-fibre bean-rich diet was as effective as a low-carbohydrate diet for weight loss, although only the bean-rich diet lowered atherogenic lipids.
