Adherence

A short-term (7-week) supervised intervention of Time-Restricted Eating (TRE) and/or High-Intensity Interval Training (HIIT) can promote long-term self-reported maintenance of these lifestyle behaviors in women with overweight/obesity, with approximately 45-46% continuing the respective interventions two years later without ongoing supervision.

If you are overweight or obese, a short, supervised period of Time-Restricted Eating (limiting eating to 10 hours a day) or High-Intensity Interval Training (3 sessions a week) can help you build the habit to continue these behaviors on your own for years. You don't need to be perfect; maintaining the habit 5 days a week is sufficient for long-term success. The key is using the initial supervised time to learn how to fit these flexible strategies into your real life, rather than relying on constant external motivation.
