Do fasting schedules matter for losing weight?

Scientists looked at many studies to see if skipping meals (intermittent fasting) works better than eating fewer calories every day (continuous restriction). They found that as long as you eat the same amount of calories, both ways lose about the same weight.
Surprising Findings
Intermittent fasting doesn’t outperform daily calorie counting when calories are equal.
Fasting is often marketed as superior due to hormonal or metabolic advantages, but this large analysis shows no added benefit beyond the calorie deficit.
Practical Takeaways
Focus on creating a consistent calorie deficit rather than adopting complex fasting schedules.

If you eat the same number of calories and protein, fasting every now and then works just as well for losing weight as eating less every day.
Cutting calories a lot all the time helps people with extra weight lose the most pounds quickly — about 11.5 kilos on average in the short term.
Eating a bit less consistently can lead to noticeable weight loss over a short period for people who are overweight or obese.
It looks like the weight‑loss you get from intermittent fasting starts to slip back after about three months, but steady calorie‑cutting keeps the loss steady, so fasting might not work as well over the long run.
If you're an adult with extra weight or metabolic issues, how much you eat matters way more than when you eat — cutting calories works the same whether you do intermittent fasting or just eat less every day, as long as the total calorie drop is the same.
