Plant-based diet can boost after-meal burn, leading to weight loss and improving cardiometabolic risk factors in overweight people, reports a new study. The findings of the study are published in the journal JAMA Network Open.
The study randomly selected overweight participants with no history of diabetes to an intervention or control group in a 1:1 ratio. For 16 weeks, volunteers in the intervention group followed a low-fat, plant-based diet based on fruits, whole grains, vegetables, and legumes with no calorie limit. The control group made no diet modifications. Neither group modified exercise or medication routines unless directed by their doctors.
Researchers applied indirect calorimetry to estimate how many calories participants burned after a standardized meal at both the start and end of the study. The plant-based group raised after-meal calorie burn by 18.7percent, on average, after 16 weeks. The control group's after-meal burn did not vary significantly.
Within just 16 weeks, participants in the plant-based group reduced their body weight by 6.4 kg (about 14 pounds), on average, than an insignificant change in the control group.
"Not only did the plant-based group lose weight, but they encountered cardiometabolic improvements that will decrease their risk for heart disease, type 2 diabetes, and other health problems," states Dr. Kahleova.
