Why Diet May Lead to Weight Gain?
Why Diet May Lead to Weight Gain?
- A good way to lose weight is by taking it slow and steady. Choose healthy foods based on nutrition rules, do some exercise that fits you, lower stress, and make sure to get enough sleep.
- Keeping insulin and leptin in check is key for weight loss. If these are out of balance, you might end up eating too much, leading to uncontrollable weight gain or a yo-yo effect.
- Having the right cortisol level is important for your body. If it is consistently too high or too low, it not only affects your weight but also can cause various health problems.
The saying "The more you restrict, the more you gain" or "The more you cut back, the more you pack" is a common struggle for many who are trying to lose weight. But before diving into weight loss, understanding the root cause of the problem is crucial because it plays a significant role in whether the weight loss journey will be successful or not.
For those working hard to shed pounds, it can be disheartening when the weight doesn't budge or, worse, increases. This phenomenon is actually related to the hormonal mechanisms involved in eating and body weight, specifically the "hunger hormone" Ghrelin, the "satiety hormone" Leptin, and the "stress hormone" Cortisol, all working together.
Ghrelin is a hormone that stimulates hunger. It is produced in the stomach and signals the brain, inducing feelings of hunger when the stomach is empty. Ghrelin levels peak before meals, causing hunger, and typically decrease about 3 hours after eating.
The functions of Ghrelin, aside from signaling to the brain that the body is feeling hungry, include:
- Increasing food intake and aiding the body in storing fat.
- Stimulating the release of growth hormone, also known as the growth hormone.
- Assisting in the control of sugar and insulin, hormones responsible for processing sugar.
- Protecting and strengthening muscles, promoting bone formation, and aiding in metabolism.
Effectively managing hunger involves controlling Ghrelin levels to prevent them from becoming too high or rising too quickly. This can be achieved by increasing the intake of good proteins, such as egg whites, fish, and beans, as these foods effectively suppress Ghrelin secretion. Avoiding high-fat foods is crucial, as they inhibit Ghrelin production more than low-fat options. Adequate sleep is essential, as insufficient sleep stimulates Ghrelin production. Consuming smaller, more frequent meals can also help control Ghrelin secretion. Including good carbohydrates, like unprocessed grains, can reduce Ghrelin levels. Lastly, minimizing stress is vital, as stress triggers increased Ghrelin production, making one more prone to feeling hungry.
Leptin was discovered in 1994, and it's a hormone that helps reduce appetite and control hunger. It is produced by fat cells (White adipocytes). When Leptin levels are high, it signals a feeling of fullness, reducing the desire to eat.

The primary role of Leptin is to regulate long-term weight balance by curbing hunger and controlling energy levels. It helps prevent the body from triggering hunger responses when energy is not needed.
Additionally, Leptin levels are low, it triggers hunger and increases food intake. The levels rise when fat cells increase or when the body feels full. In this case, if Leptin is in low quantity, it leads to continuous feelings of hunger.
Therefore, Leptin has a significant impact on weight loss individuals because when body fat decreases, Leptin levels also decrease. This signals the body that it is hungry, triggering intense hunger and cravings, leading to increased food intake.
Currently, Leptin levels can be measured through blood tests, as they directly correlate with the body's fat levels. Obesity can result in elevated Leptin levels, possibly causing Leptin resistance. This condition hinders the normal responsiveness of the brain to Leptin, making individuals feel constantly hungry and inclined to consume more food, even when the body doesn't require it.
Apart from this, the levels of hunger hormones differ between males and females, with women generally having higher levels of Ghrelin and Leptin than men. Studies also indicate that women tend to be more responsive to Leptin, influenced by factors such as genetics and increased body fat.
Moreover, Diet and exercise alone are not definitive solutions for hormonal issues; hence, their effects may be short-term. Controlling Ghrelin and Leptin levels is crucial in weight management. An imbalance in hunger hormones can lead to excessive food intake, contributing to uncontrollable weight gain and potential adverse effects on health.
Cortisol, often referred to as the "stress hormone," is produced by the adrenal glands in response to stress. It influences appetite, promotes fat storage, and serves key functions like regulating the body's stress response. This hormone aids in releasing quick energy from the liver during stressful situations. Additionally, it plays vital roles in metabolism, inflammation control, blood pressure regulation, blood sugar management, and sleep regulation.

Most importantly, maintaining appropriate cortisol levels is crucial for the body. These levels decrease during sleep and peak in the early morning before waking up. In this case, if cortisol levels are consistently high or low, it not only affects body weight but also has adverse effects on overall health.
Maintaining optimal cortisol levels involves these strategies:
- Quality Sleep: Address sleep problems like sleep apnea or insomnia for a good night's rest, crucial for keeping cortisol levels balanced.
- Regular Exercise: Incorporate consistent physical activity into your routine, promoting better sleep and stress reduction, ultimately contributing to cortisol level control.
- Stress Reduction: Practice stress-relief techniques like deep breathing or calming activities to minimize overall stress and support a balanced cortisol level.
Why Does Dieting Make You Gain Weight?
When you cut calories to lose weight, your fat cells shrink. In response, your body releases more Ghrelin (the hunger hormone) and less Leptin (the fullness hormone). This makes you feel hungrier and increases the urge to eat. Moreover, higher levels of Cortisol, the stress hormone, get released, boosting appetite and encouraging fat storage. This creates a cycle where restricting leads to gaining.
For effective weight loss, take a gradual and balanced approach. In this case, select nutrient-rich foods, maintain regular and suitable exercise, manage stress, prioritize quality sleep, and embrace a holistic lifestyle for a successful and lasting weight loss journey.
In summary, when you restrict food for weight loss
- Increased hunger results from higher Ghrelin levels in the stomach.
- Eating without a sense of fullness due to reduced Leptin from fat cells (in those of normal weight).
- Continuous eating all day because Leptin levels rise without a proper response (in overweight individuals).
- The body accumulates fats due to increased Cortisol hormone from the adrenal glands in response to stress.
The better approach is to #choosing-rather-than-restricting, and it's essential to understand how hormones work to enhance weight loss effectiveness.
If you have been experiencing the "the more you cut, the more you gain" phenomenon, consult a doctor to identify the true causes and find appropriate treatment strategies.
