What exactly is Yo Yo Dieting?
Yo Yo dieting is a type of dieting in which a person gets into the pattern of repeated weight loss and weight gain. And they achieve it themselves (under no professional nutritionist guidance) with the help of short term diets.
During this, people don’t know or focus on long term health impact. People just chase quick wins which are visibly satisfying. People start following the crash diet and achieve some weight loss. Later, they get temped and returns to their older eating habits.
This leads to weight gain. This is called Yo Yo dieting. It is called Yo Yo because body weight moves up and down just like a Yo Yo toy. Yo Yo dieting is a problem not because you don’t have a willpower to follow a crash diet or a restrictive diet, but it’s because your body don’t allow you to do it.
And it’s not just your body, everyone faces the same problem. Just that, people knows it later in the journey and then they look for someone to assist to stop the yo yo dieting.
Example of Yo Yo Dieting from A Mumbaikar's Lifestyle perspective
A 32 year old job professional in Mumbai has a practice of following long working hours in traffic-packed Andheri or Powai area of Mumbai.
He’s having too much pressure of deadline and he needs to do long commute to Borivali or let’s say Virar. The professional is smart and he heard that too much carbs are not good. He also heard that, eating less or cutting more and more carbs is good for health. So, he skip breakfast. He don’t forget to take 3 coffees (actually, black coffee because he heard its healthy) during the day so that he remains energetic.
He knows that if he don’t eat too much carb, then it’s fine and it’s good for him. So he follow a strict low carb diet for six to eight weeks. He sees a weight loss. He is happy. One fine weekend, he do lunch or dinner with their social mates and there they do stress eating (enough of dieting, one day over eating won’t harm).
On weekdays also, he also started to have late night office dinners because of clients or team parties. And within a few months, the weight comes back. This is a cycle where he first lost the weight and then slowly lost the motivation of crash diet. And his body made him to do stress eating finally. This is Yo Yo.
Psychology behind Yo Yo Dieting
The psychology behind Yo Yo dieting is related to how the human mind responds to restrictions in the diet and the stress. Most people who starts Yo Yo dieting are less disciplined. They are caught in this cycle because of emotional triggers. They start Yo Yo dieting unknowingly because they see they are getting a weight gain because of uncontrolled eating in office and at home (Trigger 1).
So they think they need start their crash diet with urgency (Trigger 2). They follow extreme crash dieting rules like cutting entire food groups and stick to a specific calorie limit which they found on internet.
They read more about good or bad food and psychologically they put in lot of restrictions (No professional guidance from a nutritionist here).
Another point is many people start aggressive diet during the week and then they reward themselves with cheat days on weekend (Trigger 3). This creates a Yo Yo dieting pattern.
Stress is playing very important role here. People have corporate deadlines, lack of sleep and fall into the comparison trap. They finally lose their willpower at the end and they break their unsustainable crash diet habit.
Over the time, these repeated diet failures conveys their brain that they need to try out new diet approach (still alone, no professional guidance). This psychology loop makes people jump from one diet to another.
Benefits of Yo Yo Dieting (Short Term Only)
Below are few short term benefits of yo yo dieting. And these really attracts people into this dieting pattern.
Quick weight loss results
Strict calorie restriction or fad diets often lead to fast initial weight loss, mainly from water weight and glycogen depletion, which can be motivating in the short term.Short-term motivation boost
Seeing the number on the scale drop quickly can increase confidence and create a sense of achievement, encouraging people to “stick to the diet” initially.Temporary structure and discipline
Following rigid diet rules can give a feeling of control, especially for individuals who feel overwhelmed by food choices or lifestyle chaos.
Is Yo Yo Dieting Worth it?
No. A strict no. Yo Yo dieting is not worth it. Yo Yo dieting may give you quick weight loss, but the long-term problems will cost you more.
You will see the effects in metabolism, hormone, and mental health. If you undergo repeated cycle of losing and gaining the weight, it will confuse your brain. Your brain won’t notice when to slow down the metabolic rate, increase the fat storage, and it will make future weight loss harder.
Yo Yo dieting brings in long-term health issues such as insulin resistance, hormonal imbalance, and emotional eating.
Here is what leading nutritionist in Mumbai – Dt. Foram Modi has to say about Yo Yo dieting.
As a nutritionist practicing in Mumbai from last 12+ years, I see this every now and then. People do yo-yo dieting after reading from internet. They doesn’t fail because they lack willpower. But they fails because the human body is designed to protect itself. Every crash diet teaches your metabolism to slow down and store more fat the next time. You are messing up the metabolic cycle. You need to repay it’s consequence over long term.
– Dt. Foram Modi (Leading Nutritionist in Mumbai)
So instead of chasing rapid result, we suggest a sustainable and hormone-friendly nutrition program, which is focused on long-term consistency.
Negative Health Effects of Yo Yo Dieting

Weight regained after dieting is often more fat and less muscle, worsening body composition over time.Higher risk of insulin resistance and diabetes
Frequent weight cycling is associated with poor blood sugar control and increased risk of type 2 diabetes.Loss of muscle mass
Crash diets often break down muscle tissue, further reducing metabolic efficiency.Nutrient deficiencies
Restrictive eating can lead to low iron, B-vitamins, calcium, and essential fatty acids.Mental and emotional stress
Guilt, food anxiety, binge-restrict cycles, and low self-esteem commonly develop with repeated dieting.
Long Term Effects of Yo Yo Dieting
Over the long term, you will face a lasting change in metabolism, hormone, and even your breath cycles. Below are long-term effects of Yo Yo dieting.
Permanent metabolic slowdown
Repeated dieting lowers resting metabolic rate, meaning your body burns fewer calories even with normal food intake.Chronic hormonal disruption
Long-term imbalance in insulin, leptin, cortisol, thyroid, and sex hormones can cause fatigue, mood swings, acne, hair fall, and stubborn weight gain.Higher risk of type 2 diabetes
Yo-yo dieting and insulin resistance are closely linked, increasing long-term diabetes risk.Loss of lean muscle mass
Muscle loss accumulates with each dieting cycle, reducing strength, metabolism, and functional fitness.Weakened relationship with food
Long-term dieting often leads to emotional eating, binge-restrict cycles, food guilt, and loss of hunger-satiety cues.Increased cardiovascular risk
Studies associate weight cycling with higher inflammation, cholesterol imbalance, and heart disease risk. As per the research on Weight variability and cardiovascular outcomes: a systematic review and meta-analysis, body weight cycles are associated with higher risk of developing cardiovascular diseases & heart attacks.
Considering above side effects, yo yo dieting is not recommended by professional nutritionists in India.
Yo Yo Dieting & Diabetes - Is there a relation?
When you go repeated cycle of weight loss and weight gain, your body’s insulin system goes through a stress cycle. As per the research, Association between weight cycling and risk of developing diabetes in adults, it is found that people who go into weight cycles are at higher risk of developing Type 2 diabetes.
Each crash diet will temporarily improve your blood sugar levels, but when your weight gains, body will see higher spike in insulin.
