Generally, it takes at least three months of consistent adherence to "no food after noon" to prevent weight regain. The specific analysis is as follows:

"No food after noon" typically refers to abstaining from food after midday. This practice can reduce fat accumulation and promote fat burning and utilization in the body, thus having a certain effect on weight loss. However, prolonged use of this method for weight loss may likely lead to malnutrition. To maintain a stable weight long-term and avoid rebounding, it's recommended to continue this regimen for at least three months after reaching the target weight to ensure the body stabilizes at the new weight.

It is advised to add an extra half hour of exercise two hours after dinner each day to help burn excess calories. You may choose to eat fresh fruits and vegetables, or replace staple foods with whole grains. These foods are low in fat and calories, minimizing excessive fat accumulation.
