How to avoid the yo-yo effect?

Research shows that up to 35% of people regain their original body weight within a year of finishing a weight-loss program, and 50% regain it within five years. The yo-yo effect often affects those who treated weight loss as a temporary phase or chose restrictive, low-calorie diets. Such an approach does not teach new eating habits, so when people return to their old ways of eating, the lost pounds return as well. However, there are ways to avoid the unwanted yo-yo effect.

Consistency is key

Whenever we start a diet, we want to see immediate results. Unfortunately, the magic of a "miracle diet" is often fleeting and leads to the unwanted yo-yo effect. For successful weight loss, we should focus on consistency. Weight reduction is a process that takes time; the recommended rate of weight loss is between 0.5 kg and a maximum of 1 kg per week (for those starting with overweight or obesity). Therefore, the foundation of effective and safe weight loss is a rational approach that leads to gradual weight reduction and lasting changes in eating habits.

Good calories

A key issue in the fight against excess weight, which can help avoid the yo-yo effect, is the appropriate caloric intake of your diet. The desire for quick results often leads us to follow a diet that is too low in energy—a mistake that can lead to a rapid return of weight once the diet ends. Typically, short-term diets provide unsustainable results in the form of water loss, glycogen depletion, and reduced gut content rather than the desired loss of body fat. Conversely, long-term diets that are too low in calories can also contribute to muscle mass loss. Additionally, excessive restrictions increase the urge to snack, making it much harder to stick to the diet.

Don't avoid protein

Restrictive, low-energy diets are usually low in protein, the body's main building block. After a weight-loss program ends, muscle mass decreases, and with that loss, the body's energy requirements drop. When you return to old habits, the lost pounds return with interest. To protect yourself against muscle loss during a diet, in addition to a properly selected caloric intake, it is important to meet your protein requirements. The amount should be about 1.2–1.5 g/kg of body weight or moreif the person on the diet is doing strength training. While resistance/strength training burns fewer calories than aerobic exercise, it protects muscle mass and helps maintain it at your baseline level during a diet.

Learning healthy eating habits

Weight loss is not a race; the battle for a slim figure is won not by the person who finishes first, but by the one who reaches their goal and is able to maintain their new body weight. When you want to shed extra pounds, it is worth introducing changes gradually and thinking about how to modify your current diet to make it healthier. It is best to start with the basics, which may sound trivial at first glance but yield the best results. Remember to drink enough water throughout the day, add vegetables or fruit to every meal, choose whole-grain products, and limit sweets in your daily diet.

Summary

Avoiding low-calorie, restrictive diets and opting for a balanced plan with appropriate caloric intake are the main points that will minimize the risk of the yo-yo effect after weight loss. But that is not all. Principles of proper nutrition and physical activity should remain a permanent part of your daily routine rather than ending once you reach your goal. A healthy diet allows for better satiety control, among other things, and this can prove to be the key to success and maintaining your target weight for years to come.
