Quick Answer
Cheat days involve eating well above your usual calorie intake once per week. This strategy can help prevent your metabolism from slowing during a calorie deficit and may help preserve muscle while losing weight.

Introduction
When dieting, constant calorie restriction can cause your body to adapt by lowering your metabolic rate. This makes further weight loss harder and can increase the risk of losing muscle. Incorporating a cheat day—where you eat in excess of your standard intake—can help keep your metabolism higher and make your diet more sustainable. Used wisely, cheat days can support both fat loss and muscle maintenance.
Understanding Cheat Days and Their Benefits
What Are Cheat Days?
A cheat day is a planned occasion, usually once a week, where you intentionally eat more calories than your normal diet allows. The goal is to give your body a break from restriction and help maintain a healthy relationship with food.
- Cheat days involve eating in large excess of your typical calorie intake.
- They are usually scheduled once per week during a period of calorie deficit.
- Cheat days can make strict diets easier to follow by providing flexibility and enjoyment.
Metabolic Rate and Adaptation
When you consistently eat fewer calories, your body adapts by lowering your metabolic rate. This is a natural survival mechanism but can slow weight loss over time. A cheat day, with a significant calorie surplus, may help counteract this adaptation by temporarily boosting metabolism.
- Prolonged calorie restriction causes metabolic adaptation, making weight loss harder.
- Occasional overeating can stimulate metabolism and help maintain higher energy expenditure.
- Cheat days can also help restore levels of hormones like leptin, which regulate hunger and metabolism.
Cheat Days and Muscle Preservation
Losing weight can sometimes lead to muscle loss, especially if calories are kept low for long periods. By including a cheat day, you may help preserve muscle mass by providing extra energy and supporting recovery.
- Cheat days may help inhibit muscle loss during weight loss.
- Extra calories can support muscle repair and growth when paired with strength training.
- Strategic overeating can also improve workout performance and motivation.
Tips for Effective Cheat Days
Cheat days can be useful, but they should be planned and balanced to avoid undoing your progress. Focus on enjoying your favourite foods in moderation, and avoid turning a cheat day into a binge.
- Plan your cheat days in advance and keep them to once per week.
- Choose foods you enjoy, but try to keep portions reasonable to avoid excessive calorie intake.
- Use cheat days to refuel, recover, and reset your motivation for the week ahead.
In Summary
Meal cheat days can help keep your metabolism higher and make dieting more sustainable. By eating in excess once per week, you may prevent metabolic slowdown and help preserve muscle during weight loss. Planning and moderation are key to making cheat days work for you.
