supplements, and meal replacement plans claiming to ensure rapid weight loss, most lack any scientific evidence. There are, however, some strategies backed by science that do have an impact on weight management.
Several studies have indicated that short-term intermittent fasting, which is up to 24 weeks in duration, leads to weight loss in overweight individuals.
The most common intermittent fasting methods include the following:
Alternate day fasting (ADF): Fast every other day and eat normally on non-fasting days. The modified version involves eating just 25–30 percent of the body's energy needs on fasting days.
The 5:2 Diet: Fast on 2 out of every 7 days. On fasting days eat 500–600 calories.
If someone wants to lose weight, they should be aware of everything that they eat and drink each day. The most effective way to do this is to log every item that they consume, in either a journal or an online food tracker.
