How to Keep the Weight Off
Losing weight and keeping it off are different skills. Here's what people who've kept it off actually do.
The short version
- Regain is very common, and it's driven largely by biology. It doesn't mean you failed.
- People who maintain weight loss tend to stay active, keep an eye on their weight and eat in a consistent pattern.
- Set a "return zone": a weight, usually 3 to 5 pounds above your goal, at which you take action.
- Obesity can be a long-term condition. Some people need ongoing support or treatment, just as with blood pressure.
Why regain happens
After weight loss, your body wants the weight back. You burn fewer calories and feel hungrier, and those changes can last for years. Add the fact that many diets end ("I'm done!") and old habits return, and it's easy to see why regain is common.
None of this means maintenance is hopeless. It means it needs a plan.
What successful maintainers do
The National Weight Control Registry tracks thousands of people who've lost at least 30 pounds and kept it off for at least a year. On average they've lost more than 60 pounds and kept it off for more than five years. It's a self-selected group, so it can't prove what causes success, but the patterns are consistent:
- Very active. About 90% exercise roughly an hour a day on average, and walking is the most common activity.
- Regular weigh-ins. About 75% weigh themselves at least once a week.
- Consistent eating. Many keep a similar pattern across weekdays and weekends. Most eat breakfast (78%), though trials show breakfast itself isn't magic.
- Limited screen time. About 62% watch fewer than 10 hours of TV a week.
There's no single diet in common. They lost the weight in all sorts of ways, and 98% say they changed their food intake in some way.
Build your maintenance plan
Find your new calorie level
Add back calories slowly, 100 to 200 at a time, while watching your weekly average. Your maintenance level will be lower than it was at your starting weight, and that's normal. Recalculate here.
Protect your activity
Exercise doesn't do much on its own for losing weight, but it's one of the best predictors of keeping it off. Many experts suggest around 200 to 300 minutes of moderate activity a week for maintenance, plus strength training to hold onto muscle.
Set a return zone
Pick a number, usually 3 to 5 pounds above your goal. When your weekly average crosses it, you go back to the simple things that worked: a week or two of tracking, cutting out extras, more walking. Catching 5 pounds is far easier than catching 25.
Keep some of your structure
Permanent perfection isn't the goal. Keep the two or three habits that gave you the most results, like a protein breakfast, no sugary drinks, or a daily walk, and loosen up on the rest.
Plan for disruptions
Holidays, travel, injuries, new jobs and breakups are when weight comes back. Decide ahead of time what the "minimum version" of your routine looks like. See getting back on track.
If you've used medication
Medication doesn't cure obesity. It treats it while you're taking it. In the extension of one large semaglutide trial, people regained about two-thirds of their lost weight within a year of stopping. If you plan to stop, make a plan with your prescriber first. Staying on long term is also a legitimate choice. See weight-loss medications.
