Energy balance

Combining Time-Restricted Eating (TRE) with Energy Restriction (ER) provides no additional benefit for weight loss or fat mass reduction compared to TRE alone.

If you are already practicing Time-Restricted Eating, you do not need to add explicit calorie counting or energy restriction to achieve weight loss. TRE alone is sufficient for significant fat and weight reduction. Adding calorie restriction does not provide extra benefits for weight loss in this context.

GoodRefutesHIGH confidence
Our findings imply that practicing TRE alone or in combination with ER is beneficial for weight loss and fat mass reduction... no differences between the subgroups.
