STUDIES: 4- AND 6-HOUR TIME-RESTRICTED EATING (TRE) DIETS, NO FOOD LIMITS RESULT IN WEIGHT LOSS

“The findings of this study are promising and reinforce what we’ve seen in other studies — fasting diets are a viable option for people who want to lose weight, especially for people who do not want to count calories or find other diets to be fatiguing,” Varady said. 

…participants in both daily fasting groups reduced calorie intake by about 550 calories each day simply by adhering to the schedule and lost about 3% of their body weight. The researchers also found that insulin resistance and oxidative stress levels were reduced among participants in the study groups when compared with the control group.

4- And 6-Hour Time Restricted Eating TRE Diets

Two daily fasting diets, also known as time-restricted feeding diets, are effective for weight loss, according to a new study published by researchers from the University of Illinois at Chicago.

The study reported results from a clinical trial that compared a 4-hour time-restricted feeding diet and a 6-hour time-restricted feeding diet to a control group.

“This is the first human clinical trial to compare the effects of two popular forms of time-restricted feeding on body weight and cardiometabolic risk factors,” said Krista Varady, professor of nutrition at the UIC College of Applied Health Sciences and corresponding author of the story.

COMMENTARY

Time-restricted eating brought my weight down from 142 pounds to 136, which is close to what was found on the study; not much, but every pound counts. The improved insulin resistance was reassuring but I am surprised they didn’t find any effects on the HDL, LDL and triglycerides.

The most detailed study on time restricted eating and fasting in general was in the New England Journal of Medicine in December 26, 2019. That excellent article went into all kinds of metabolic pathways that are benefited by fasting.

Good sleep,  diet and exercise can be very helpful.
