Doctors Explain Intermittent Fasting Weight-Loss Expectations for Indians
Intermittent fasting means eating during certain hours and fasting during the rest.
Doctors say weight loss is different for every person.
A reasonable goal for many adults is about 0.5–1 kilogram each week.
At first, some of the lost weight may be water rather than body fat.
Later, people may lose about 0.25–0.5 kilograms of fat each week.
Some studies found that people lost around 2–5 kilograms over 8–12 weeks.
These numbers are only estimates, so people may lose more or less.
The doctors say fasting works best when people avoid overeating and make healthy food choices during eating hours.
A gradual loss of 0.5–1 kilogram per week is considered reasonable for many adults.
Early weight loss may be mostly water, while later losses are more likely to reflect fat.
Studies suggest time-restricted eating may lead to roughly 2–5 kilograms of loss over 8–12 weeks.
Results vary, with some people losing less or more than those study estimates.
Doctors warn that overeating or choosing unhealthy foods during eating periods can undermine fasting efforts.
