Yo-yo dieting, also known as weight cycling, is the repeated loss and regain of weight over time. Many people resort to yo-yo dieting in an attempt to lose weight quickly or to fit into a specific social standard.
However, this type of dieting has been linked to several negative health consequences. In this article, we will discuss why yo-yo dieting is harmful to your health.
1. Slower Metabolism
A key issue with yo-yo dieting is that the body’s metabolism slows down with each cycle. When you lose weight, your body naturally lowers its metabolic rate in an attempt to conserve energy.
However, when you quickly gain the weight back, your metabolic rate does not immediately readjust. This can result in a slower metabolism, making it harder for you to lose weight in the future.
2. Increased Risk of Heart Disease
Yo-yo dieting has been linked to an increased risk of heart disease.
A study published in the New England Journal of Medicine found that men who yo-yo dieted had a higher risk of heart attack, stroke, and death from heart disease compared to those who maintained a stable weight. The study also found that the risk increased with each cycle of weight loss and gain.
3. Increased Risk of Type 2 Diabetes
Yo-yo dieting has also been linked to an increased risk of type 2 diabetes. A study published in Diabetes Care found that women who yo-yo dieted had a higher risk of developing type 2 diabetes compared to those who maintained a stable weight.
The study found that the risk increased with each cycle of weight loss and gain.
4. Nutrient Deficiencies
Yo-yo dieting can lead to nutrient deficiencies. When you lose weight rapidly, you often cut out certain foods or food groups that are necessary for a healthy diet.
This can result in a deficiency of vitamins, minerals, and other important nutrients that your body needs.
5. Poor Mental Health
Yo-yo dieting can also have negative effects on your mental health. The constant cycle of weight loss and gain can be emotionally draining and lead to feelings of disappointment, frustration, and low self-esteem.
This can make it more difficult to maintain a healthy lifestyle in the long run.

6. The Weight Loss is Only Temporary
The weight loss achieved through yo-yo dieting is often temporary. When you lose weight rapidly, much of the weight is lost from water and muscle rather than fat. This can result in a decrease in muscle mass and an increase in body fat percentage.
When you regain the weight, you often regain more body fat than you had originally, which can lead to a lower metabolic rate and make it harder to lose weight in the future.
7. Increased Risk of Gallstones
Yo-yo dieting has been linked to an increased risk of gallstones.
A study published in the American Journal of Gastroenterology found that women who yo-yo dieted had a higher risk of developing gallstones compared to those who maintained a stable weight. The study also found that the risk increased with each cycle of weight loss and gain.
8. Unhealthy Relationship with Food
Yo-yo dieting can also lead to an unhealthy relationship with food. When you constantly restrict food or go on drastic diets, it can lead to feelings of guilt and shame when you inevitably “cheat” or regain the weight.
This can result in disordered eating patterns and a negative relationship with food.
9. Increased Risk of Depression
A study published in the Journal of Psychosomatic Research found that yo-yo dieting was associated with an increased risk of depression.
The study found that the risk increased with each cycle of weight loss and gain and was higher in women compared to men.
10. Long-Term Weight Gain
Yo-yo dieting has also been linked to long-term weight gain. A study published in the International Journal of Obesity found that people who yo-yo dieted were more likely to gain weight in the long run compared to those who maintained a stable weight.
The study found that the weight gain was due to a slower metabolism and an increase in appetite and cravings.
Overall, yo-yo dieting can have many negative health consequences.
It can lead to a slower metabolism, an increased risk of heart disease and type 2 diabetes, nutrient deficiencies, poor mental health, temporary weight loss, an increased risk of gallstones, an unhealthy relationship with food, an increased risk of depression, and long-term weight gain. Instead of resorting to fad diets and extreme weight loss methods, focus on making sustainable lifestyle changes that promote overall health and well-being.
