The Claim
A 12-week intermittent fasting program results in sustained weight loss maintenance for at least one year following program completion in humans.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who complete a 12-week intermittent fasting program maintain their weight loss for at least one year after stopping the program.
See the scientific wording
A 12-week intermittent fasting program enables people to maintain weight loss for at least one year after the program ends.
When a person eats less on certain days, their body uses stored fat for energy instead of sugar from food. This lowers a hormone called insulin, which tells the body to burn fat and stop feeling hungry. As a result, the person eats less over time and keeps the weight off.
What the research says
1 studyStudy: The Effect of 4:3 Intermittent Fasting on Weight Loss at 12 Months
People who followed a plan of eating very little on 3 days a week and eating normally on the other 4 days lost more weight and kept it off after a year than people who ate less every day. This suggests intermittent fasting can help people maintain weight loss long-term.
