Where Is Hormonal Weight Gain

 Everything You Need to Know About Hormones and Weight

Hormones are signaling molecules involved in a wide range of body functions. Glands like the pituitary, thyroid, parathyroid, and adrenal glands release hormones into the bloodstream. They then go to tissues and organs. Hormones play a role in almost all aspects of health, including sexual function, growth and development, mood, appetite, and metabolism. As a result, hormonal dysregulation, which occurs when your body produces too little or too much of a hormone, can have a big influence on your health, including your weight.
The impact of hormones on weight is explained in this article. Hormones play a role in hunger and fullness.
Hormones assist your body maintain energy levels by regulating your hunger. Hunger is triggered by certain hormones. Others indicate that you've eaten enough to eat and prevent you from eating more. Weight gain or loss can be caused by an imbalance in appetite-controlling hormones.

Hormones that cause hunger

When your body needs food, the endocrine and nervous systems set in motion a chain of events that encourage you to eat. The migrating motor complex is activated by gastrointestinal hormones such motilin, which activate a cycle of contractions related in the development of hunger. Some of the most essential hormones and other substances involved in hunger stimulation are listed below:

  • Ghrelin. Ghrelin is also known as the "hunger hormone." It stimulates the hypothalamus, a brain region that regulates appetite. In addition to affecting food intake, ghrelin is involved in the sleep-wake cycle, glucose metabolism, and other activities.
  • Motilin. In the small intestine, the hormone motilin is produced. Motilin stimulates your intestines to contract when you're fasting, notifying your brain that you need to eat.
  • Y-peptide (neuropeptide) (NPY).  To increase food intake, the brain releases NPY, a peptide made up of a short chain of amino acids. Ghrelin and leptin are hormones that regulate NPY production and release.
  • A protein that has a link to agouti (AgRp). AgRp is another peptide produced by the brain. Ghrelin increases food intake by stimulating its production.

Hormones of satiety (fullness)

Some of the primary hormones that cause satiety and restrict food intake are as follows:

Cholecystokinin is a hormone that is produced by the body (CCK). CCK is a hormone produced by small intestine cells in response to luminal nutrients, particularly fat and protein. It suppresses appetite through triggering satiety centers in the brain, as well as gallbladder contraction and pancreatic secretions, all of which are important for digestion.

Glucagon-like peptide-1 is a peptide that is similar to glucagon (GLP-1). GLP-1 is a hormone generated by gut cells in response to nutrition intake. GLP-1 reduces food intake and increases fullness by slowing stomach emptying and interacting with the brain.

YY, a pancreatic peptide (Peptide YY). Another hormone produced in the small intestine is peptide YY. It's secreted in reaction to food consumption and binds to brain receptors, reducing hunger. It also causes food to travel more slowly through the digestive tract.

Leptin. Leptin is a hormone that fat cells and other body organs secrete. It's best recognized for being a fullness hormone. Leptin suppresses the hunger-inducing peptides NPY and AgRp while increasing fullness-inducing peptides, resulting in a decrease in appetite.

Insulin. Insulin is a hormone produced by the pancreas. It regulates blood sugar levels and maintains energy balance. Following a meal, insulin levels rise. Insulin works with the brain to help you eat less.
Obestatin. Obestatin is a hormone that suppresses the appetite. It counteracts the hunger-inducing effects of ghrelin. Scientists are still investigating obestatin's effects on hunger and fullness, and more research is needed.

This is not an exhaustive list. Other molecules, such as the peptide nesfatin-1 and the hormone oxyntomodulin, are implicated in appetite control.

Hormones have an impact on body weight.

Certain hormones in the body are in charge of fat storage and breakdown. Hormones also have an impact on energy expenditure, or how many calories your body burns each day.

As a result, changes in hormone levels can cause weight gain or reduction, as well as the buildup of body fat in specific locations.

The thyroid, for example, secretes hormones that are involved in metabolic regulation.

When the thyroid gland is overactive, it generates too much thyroid hormone. The body becomes hypermetabolic, meaning it burns more calories as a result of this. The medical word for this illness is hyperthyroidism.

On the other side, an underactive thyroid, which is characterized by low thyroid hormone levels, causes a reduction in energy expenditure.

This explains why people with hyperthyroidism may lose weight while those with hypothyroidism may gain.

Insulin is another hormone that has the ability to influence body weight.

Insulin is required for cells to utilise glucose for energy and store it as glycogen for later use. Insulin is also necessary for the storage of energy as fat and the prevention of fat breakdown in order to maintain body weight.

It's crucial to keep insulin levels within a certain range. Insulin resistance occurs when cells stop responding to insulin properly as a result of high insulin levels over time.

According to human and animal studies, this can lead to issues with hunger and fullness hormones, as well as increased fat deposition in organs such as the liver and a reduced metabolism. Cortisol promotes appetite and causes fat to be transferred to the abdomen, especially for energy-dense, highly appealing diets high in fat and sugar.

Chronically stressed adults and people with Cushing's syndrome, a disorder that causes cortisol levels to rise, have cortisol dysregulation. Other hormones that affect body weight and fat distribution include glucose-dependent insulinotropic peptide, leptin, asprosin, and estrogen.

Medical issues, age, and weight increase can all affect hormone levels.
Many things can influence hormone levels, including:

medical diagnosis age body weight
Many hormones are affected by high body fat levels, as found in people who are overweight or obese, including:
  • estrogen \stestosterone \sghrelin \sleptin \sobestatin
  • Obese men, for example, are more likely than men of normal weight to have low testosterone levels.
  • The loss of a protein called sex hormone-binding globulin (SHBG), which transports testosterone to the body's tissues, is mostly to blame. Insulin resistance causes the decrease of SHBG in obese people.

In men, low testosterone levels are linked to an increase in body fat, particularly in the abdomen, and a loss of muscular mass. Obesity is significantly linked to anomalies in the fullness hormone leptin, such as hyperleptinemia (leptin overproduction) and leptin resistance (the body's failure to respond to leptin effectively).

Reduced sensitivity to leptin, which regulates satiety, may lead to excessive calorie consumption and weight gain. High levels of insulin and asprosin, a hormone that promotes appetite, are also linked to obesity. Menopausal women are more likely to accumulate body fat, particularly in the middle.
Medical diseases such as polycystic ovarian syndrome, hypothyroidism, Cushing's disease, and diabetes can also cause hormonal dysregulation and have an impact on body weight. People who are undergoing gender-affirming hormone therapy often acquire weight. Remember that hormone levels can be altered by a variety of different variables, such as pregnancy, drug use, and so on.

Hormones are influenced by lifestyle and diet.

Your lifestyle might have a big impact on the hormones that control your weight. Hormonal variations have been linked to diet, activity levels, and chronic stress.


The foods and beverages you consume on a regular basis can have a big impact on your overall health, especially your hormonal health. Hormonal dysregulation has been linked to diets high in ultra-processed foods, added sugar, and refined carbs, according to research. Diets high in added sugar, especially sugar-sweetened beverages, have been associated to insulin resistance and increased leptin levels, for example.

Furthermore, evidence suggests that high-protein, moderate- to low-carbohydrate diets have a better influence on fullness and hunger hormones than higher-carb, lower-protein diets.
Diets high in ultra-processed foods and added sugar may enhance hunger hormones such as NPY while blunting the action of fullness hormones such as CCK. Binge eating and weight gain may occur as a result of these side effects.

Furthermore, a high-processed-food diet exposes you to hormone-disrupting chemicals like phthalates.. These chemicals have been shown to change hormones that control appetite, satiety, and food preferences, as well as promote insulin resistance, all of which can lead to weight gain.
Diet can influence the hormones that influence weight gain in a variety of ways.

In general, for overall health, including hormonal health, a balanced diet rich in whole, minimally processed foods and low in ultra-processed foods and added sugar is preferable. Hormones are influenced by a variety of other things.
Hormones that regulate body weight can be affected by sleep, activity, and stress. It is critical to get adequate sleep in order to maintain good health. Hormonal imbalance is linked to not getting enough sleep.

  • Sleep deprivation has been related to insulin and leptin resistance, as well as a disruption in hunger hormones, which can lead to an increase in appetite, a decrease in fullness, overeating, and weight gain.
  • Exercising might also affect hormone levels.
  • According to research, increasing physical activity can:
  • enhance insulin sensitivity in the body boost testosterone levels in men
  • lower leptin levels in overweight and obese persons
Stress management is also necessary for a balanced hormonal response. Chronic stress can affect the hormones that control hunger, leading to an increase in calorie consumption and weight gain. As a result, stress management is a crucial aspect of achieving optimal hormonal health and maintaining a healthy body weight.

Last Word

Hormones regulate body weight through controlling hunger, fullness, metabolism, and fat distribution. In research, it has been demonstrated that diet, lack of sleep, activity levels, body fat percentage, stress exposure, and medical disorders all have an impact on hormonal health.

Following a good and balanced diet, getting adequate sleep, detecting underlying medical disorders, controlling stress, and engaging in physical activity are just a few of the scientifically accepted methods for promoting healthy body weight and hormone equilibrium.
