We will tell in the article how to fight yoyo effect and how to once and for all lose weight.

Yoyo effect doesn’t avoid men or women, younger or older. Unfortunately, yoyo effect doesn’t concern only the fat on the belly but also endangers health. It doesn’t matter which diet you are on, numbers say the same. Diets don’t work. Therefore not from the longer time aspect. Of course, you can be on a diet and lose weight but in a year or two, your weight is back and you are breaking your head why this yo-yo effect has chosen you.

What is yo-yo effect?

Yoyo effect or yo-yo diet is very frequently happening situation when after impulsive weight loss, you are gaining the weight back. If this process is repeated multiple times, vicious circle happens out of it and this leads to complicated weight reduction and causes negative impact on your metabolism, health and body. [2]

What is yo-yo effect?

Why does yo-yo effect is harmful to you?

We will explain it on the individual health problems which yo-yo effect can cause. It is a very big shock for the body if you lose weight during a short time, these kilograms are back in a year and more often with the addition. Read about 6 possible negative impacts of yo-yo effect.

1. Causes increased appetite

Fat cells produce hormone leptin which communicates with brain and sends the signals about body having the sufficient amount and brain consequently translates it with the feeling of a full stomach. If you are losing weight, you are losing fat and less fat means less leptin. This is the reason why we feel hunger during diets.

In addition, our body slows down all the processes to maintain energy, and that is why in time of quitting diet, you have increased appetite but burn only minimum of calories. This is partially the reason why after several cycles of diet you can expect weight higher than before diet. [1] Let’s have a look at the numbers. People who had lost weight in short time, has gained 30-65% of original weight in one year. [3] In addition, one of three people on diet, gains more kilograms than before diet. [4]

2. Causes higher proportion of fat and less muscles

In time of yo-yo effect when you are gaining weight back, fat is sticking on you more quickly than the muscles. This causes that percentage of fat is growing two times higher. One analysis of research has confirmed that 11 out of 19 studies has proven predisposition of increased amount of fat, mostly on the belly, as the consequence of yo-yo diet. [5] [6]

The second problem is that while you are losing the excess kilograms, you are losing not only fat but also muscles. [7] If you gain the weight back after diet, fat is gained more easily and this leads to higher loss of muscles eventually. It is hand in hand with weakening of your physical condition and power. [8] If this circle diet-gaining weight is repeated all the time, you’ll gain three times more kilograms composed of fat and minimum of muscles. [1]

Because of this, it is very important to exercise during weight loss. The suitable strength training for the strengthening of muscle is ideal choice in combination with cardio training. Exercising signalises the body to support muscle growth although fat is gradually disappearing out of body. [9] Don’t forget that during weight loss, the need for protein increases in the body. That is why you should reach for quality sources of proteins which can help you to reduce muscle loss. [10] [11]

3. Increases risk of cardiovascular diseases

Only a few kilograms can cause big changes in your body. You will be predisposed to inflammation which normally help to fight against diseases and infections and this can lead to damage of the heart and resistance of insulin. [1]

Continual changes of the weight are linked with the narrowing of the arteries. [12] Gaining of weight, more than obesity themselve, increases risk of cardiovascular diseases. [14] With regard to study with 9 509 adults, increasing the risk of cardiovascular diseases is directly dependent upon weight jumping in your weight. More kilograms you lose and gain during yo-yo effect, more risk you are exposed to. [15] Analysis of few studies have shown that big differences in weight over time doubled probability of death for heart failure. [16]

4. Can lead to type 2 diabetes

Each phase of losing weight and gaining weight influences also hormones, concretely stress hormone cortisol. Increased level of cortisol supports fat storage around the belly and this increases the risk of diabetes and heart failures. [1]

Belly fat is linked with diabetes more often than fat in the area of legs, hips or arms. Although the direct coherence of yo-yo effect and diabetes haven’t been proven in researches equally. Intersection of studies has pointed out on the fact that predisposition of type 2 diabetes had confirmed 4 out of 17 studies. [17] [18]

5. Is the cause of high blood pressure

Gaining of weight, including increasing of weight as the consequence of yo yo effect leads to high blood pressure. What’s worse, yoyo effect can block the healthy benefit of weight loss on the blood pressure in the future.

Study on 66 adults has found out that those who were in a yo-yo diet, had less success at the blood pressure stabilization during weight reduction. [22] However, long time study has claimed that this effect can be lost in 15 years which means that absurd dieting in young age won’t have an effect on health in the middle ages. [23]

6. Causes frustration

It can be very stressful to see that all the hard work and abnegation are gone after diet and the only one that hasn’t left you is yo-yo effect. The fact is that people who experienced yo-yo effect on their own are according to researchers unsatisfied with their life and health. [12]

According to another research, yo-yo effect is not linked with depression, self-harming or negative personal phenomena. [13] Because of this, if you had problems with yo-yo effect in the past, don’t let to feel frustrated because of it. Maybe you had experienced few diets which didn’t work in the past but do not consider it as a failure. It means that it’s time to stand up the yo-yo effect and fight.
