The objective of this study was to evaluate the effect of beverages high in plant-protein and soluble fiber on satiety, appetite, hunger and subsequent food intake in healthy young men. This was a randomized crossover study with 30 normal weight male participants, BMI 23.6 ± 1.6 and age 22 ± 1.4. Volunteers consumed one high carbohydrates control (B) and 3 treatments on different days with 3-day washout period. Beverages had similar viscosity and energy content (238 ± 3.8 Kcal). The blank contained (B)-0 g protein/2g fiber), High protein (HP)-30 g protein/2g fiber, High Fiber (HF)-0 g protein/11g fiber and High protein high fiber beverage (HPHF)-30g protein/11g fiber. Visual Analogue Scales VAS were used for subjective satiety, hunger and appetite. Subsequent energy and macronutrient intake was measured by difference after consuming lunch ad libitum. Beverages HP, HF and HPHF showed higher satiety effect than B after 2 and 3 hours post consumption (P = 0.02). HP showed the most prolonged effect on satiety (4 h) compared to the control (P = 0.02). Appetite control was not different between treatments but significant differences were observed against the control after 2 h of consumption (P = 0.01). No differences on hunger perception, subsequent energy or macronutrient intake were observed among all beverages (P > 0.05). The current study demonstrates that HPHF, HP and HF beverages led to improved satiety over high carbohydrate beverages. In conclusion, beverages formulated with plant-based proteins, soluble corn fiber or both may be an effective strategy to promote satiety as part of an overall weight management plan.展开更多
