Engineering 2017, Volume 3, Issue 5,   Pages 716-725 doi: 10.1016/J.ENG.2017.03.010

Abstract: In addition, high-fiber diets have been associated with reduced nutrient utilization and pig performanceHowever, recent reports are often contradictory and the negative effects of high-fiber diets are influencedSeveral strategies have been employed to ameliorate the negative effects associated with the ingestion of high-fibermode of action of exogenous enzymes on the metabolic and physiological responses in pigs that are fed high-fiberinto the use of exogenous enzymes to improve the utilization of high-fiber diets by pigs.

Low-carbohydrate diets lead to greater weight loss and better glucose homeostasis than exercise: a randomized

Frontiers of Medicine 2021, Volume 15, Issue 3,   Pages 460-471 doi: 10.1007/s11684-021-0861-6

Abstract: Lifestyle interventions, including dietary adjustments and exercise, are important for obesity management. This study enrolled adults with overweight or obesity to explore whether either low-carbohydrate diet (LCD) or exercise is more effective in metabolism improvement. Forty-five eligible subjects were randomly divided into an LCD group (n=22) and an exercise group (EX, n=23). The subjects either adopted LCD (carbohydrate intake<50 g/day) or performed moderate-to-vigorous exercise (≥30 min/day) for 3 weeks. After the interventions, LCD led to a larger weight loss than EX (−3.56±0.37 kg vs. −1.24±0.39 kg, P<0.001), as well as a larger reduction in fat mass (−2.10±0.18 kg vs. −1.25±0.24 kg, P=0.007) and waist circumference (−5.25±0.52 cm vs. −3.45±0.38 cm, P=0.008). Both interventions reduced visceral and subcutaneous fat and improved liver steatosis and insulin resistance. Triglycerides decreased in both two groups, whereas low-density lipoprotein cholesterol increased in the LCD group but decreased in the EX group. Various glycemic parameters, including serum glycated albumin, mean sensor glucose, coefficient of variability (CV), and largest amplitude of glycemic excursions, substantially declined in the LCD group. Only CV slightly decreased after exercise. This pilot study suggested that the effects of LCD and exercise are similar in alleviating liver steatosis and insulin resistance. Compared with exercise, LCD might be more efficient for weight loss and glucose homeostasis in people with obesity.
