Surprising Findings
The calorie‑cut group lost weight initially but regained it, while the TRE group never lost weight yet stayed stable.
Most people assume that any diet that produces a short‑term loss will keep going, and that TRE automatically leads to loss because of reduced eating time.
Practical Takeaways
If you struggle with constant calorie tracking, try an 8‑hour eating window to improve sleep and energy without risking weight regain.

People with obesity who tried time-restricted eating kept their weight steady after finishing the program, but those who cut calories lost about 1.6 kilos a month later—though they gained it back within three months.
People stuck with time-restricted eating and calorie cutting about the same amount after their supervised program ended — neither one was clearly better for long-term follow-through.
People who keep eating only within a set time window say they sleep better, feel more energetic during the day, and have happier digestion, but they also notice they get hungry in the morning and find it hard to fit the eating schedule into work or family life.
People staying on a low‑calorie diet say they’re more aware of what they eat and portion sizes, yet they also feel anxious about counting food, get stronger cravings, and sometimes binge eat.
Some people find it easier to stick to time-restricted eating — like only eating during an 8-hour window — than to cutting calories every day.
