The study by Thayer found that the reason why people tend to snack in the afternoon is because this is the lowest point of energy and mood of the day. When people are tired and stressed, they are more likely to reach for unhealthy snacks for a quick boost of energy and satisfaction.

Exercise can help to regulate mood and energy levels. A five-minute walk can help to improve circulation, reduce stress, and boost endorphins, which have mood-boosting effects.

The study found that people who went for a five-minute walk in the afternoon reported feeling less tired and stressed, and they were also less likely to snack.

Of course, exercise is not a magic bullet for weight loss. It is important to combine exercise with a healthy diet and regular sleep to achieve your weight loss goals.
