Comparing the influence of early and late time-restricted eating with energy restriction and energy restriction alone on cardiometabolic markers, metabolic hormones and appetite in adults with overweight/obesity: per-protocol analysis of a 3-month randomized clinical trial

In simple terms

This study is like a fair race where people were randomly assigned to different diets, and we watched who lost more weight and felt less hungry. We can say one diet helped more with losing fat, but we can't say it's the only way to get healthy — other diets worked just as well for things like blood sugar and cholesterol.
