When the scale feels stuck despite your best efforts, the answer might be hiding in plain sight. Sure, diet and exercise matter, but hormones — the body’s chemical messengers — play a critical role in weight management. They influence how we feel, when we eat, how we store energy, and even how our metabolism functions. A hormonal imbalance can lead to stubborn weight gain, sluggishness, and difficulty staying consistent with health goals.
Understanding what hormone controls metabolism or how others affect hunger, fat distribution, and energy storage can help you unlock the key to long-term weight management. By addressing them holistically, you empower your body to function at its absolute best. Below, we’ll cover nine hormones that impact your weight, along with tips to nurture balance and reclaim your health.
1. Insulin
The Role
Ever wondered why it’s so hard to say no to sugary snacks? Insulin might be the reason. This hormone’s job is to regulate blood sugar levels, either by directing glucose into cells for energy or storing it as fat for later use. Consistently high insulin levels, triggered by diets full of refined carbs and processed foods, can lead to fat storage and insulin resistance. Over time, this makes weight loss an uphill battle.
How to Improve It
Stabilizing insulin starts with mindful eating. Opt for complex carbohydrates, healthy fats, and lean proteins to maintain steady blood sugar levels. Incorporating fiber-rich foods, like vegetables and whole grains, can also help reduce spikes. Finally, exercise plays a significant role—just 20-30 minutes of activity daily can improve insulin sensitivity and bring balance to this vital hormone.
2. Leptin
The Role
Leptin is known as the “satiety hormone” because it helps regulate hunger by signaling to your brain when you’ve had enough to eat. However, in cases of leptin resistance—often linked to obesity—the brain stops responding to these signals, leaving you feeling hungry even after meals.
How to Improve It
Quality sleep is one of the simplest ways to improve leptin levels. Poor sleep disrupts hormone signals, leaving you hungrier and less satisfied. Prioritize whole, unprocessed foods and monitor portion sizes to support leptin sensitivity. Remember, this isn’t about restriction—it’s about giving your body the nourishment it needs while avoiding inflammation caused by processed foods.
3. Ghrelin
The Role
One of the major hormones responsible for weight gain in women is ghrelin, which is responsible for hunger and appetite regulation. Ghrelin is produced in the stomach, and its levels rise before meals to stimulate appetite, then decrease after eating. However, studies have shown that women tend to have higher levels of ghrelin compared to men, making them more prone to overeating and weight gain.
How to Improve It
Eating balanced meals with protein and fiber can help keep ghrelin levels stable throughout the day. Avoid skipping meals or going long periods without eating, which can trigger spikes in ghrelin production. Also, prioritize stress management techniques like meditation or yoga, as increased stress hormones have been linked to higher ghrelin levels.
4. Cortisol
The Role
Known as the “stress hormone,” cortisol is released in response to physical or emotional stressors. While short-term spikes are beneficial for survival, chronically high cortisol levels (common in our fast-paced, modern society) can have negative effects on the body. These include increased blood pressure, weight gain, impaired immune function, and disrupted sleep patterns.
How to Improve It
Quality sleep can also help regulate ghrelin levels. In addition, incorporating healthy fats into meals can help suppress ghrelin production and keep you feeling full for longer periods. Staying hydrated with water and herbal teas throughout the day can also help reduce hunger pangs caused by ghrelin spikes.

5. Thyroid Hormones
The Role
If you’re wondering what hormone controls metabolism, look no further than the thyroid hormones—T3 (triiodothyronine) and T4 (thyroxine). These hormones regulate metabolic rate, energy expenditure, and fat burning. They are considered the main hormones that increase metabolism. An underactive thyroid (hypothyroidism) can slow your metabolism, making it far more difficult to lose weight, even with great habits in place.
How to Improve It
Certain nutrients are essential for thyroid health. Iodine, found in foods like seaweed and iodized salt, supports the production of thyroid hormones. Selenium and zinc, found in Brazil nuts and shellfish, also play an important role. If you’re experiencing symptoms like unexplained weight gain, fatigue, or hair loss, it’s worth consulting a healthcare provider to investigate your thyroid function further.
6. Estrogen
The Role
Estrogen, the primary female sex hormone, affects how and where your body stores fat. Imbalances in estrogen, whether due to hormonal shifts in menopause or lifestyle choices, can impact weight distribution. For instance, high levels of estrogen might cause fat to accumulate around the hips and thighs, while low estrogen levels are often linked to abdominal fat.
How to Improve It
Add fiber-rich foods to your plate, such as leafy greens and legumes, to help the body flush out excess estrogen. Exercising regularly, particularly with strength training, is another great tool to harmonize estrogen levels. For those dealing with severe hormonal shifts, hormone replacement therapies under professional guidance can be life-changing.
7. Testosterone
The Role
While testosterone is more commonly associated with men, this hormone is equally important for women. Testosterone builds muscle, burns fat, and supports energy levels. Low testosterone can make it difficult to build and maintain lean muscle mass, resulting in slower metabolism and increased fat storage.
How to Improve It
Strength training isn’t just for aesthetics—it’s one of the most effective ways to naturally boost testosterone. Nutritionally, increase your intake of healthy fats found in foods like avocados, nuts, and fish. Keep an eye on your sleep schedule, as inadequate rest can lower testosterone, leaving you feeling sluggish and unmotivated.
8. Adiponectin
The Role
Adiponectin is a hormone that enhances your muscles’ ability to use carbohydrates for energy while promoting fat-burning. The higher the levels of adiponectin, the more efficiently your body can burn calories. Low levels of this hormone are commonly associated with obesity and metabolic disorders, making it another key player when addressing which hormone functions to increase metabolism.
How to Improve It
Physical activity is a major driver of adiponectin production. Incorporate fun, sustainable forms of exercise like swimming, hiking, or cycling into your routine. Add omega-3 fatty acids to your meals by including salmon, chia seeds, and walnuts, which can naturally increase this hormone.
9. Peptide YY (PYY)
The Role
PYY is a gut hormone that helps curb your appetite. When you eat, PYY is released from the gut to signal to your brain that you’re full. Low levels of PYY can lead to overeating and difficulty recognizing when it’s time to stop eating.
How to Improve It
Eating high-fiber, high-protein foods is the best way to naturally boost PYY levels. Meals that include ingredients like lean chicken, eggs, beans, and vegetables can leave you feeling full and satisfied. Avoid processed foods—they’re known to suppress PYY and trigger increased food intake.
10. Glucagon Like Polypeptide Type 1 (GLP-1)
The Role
GLP-1 is a intestinal hormone that regulated blood sugar levels by increasing insulin from the pancrease, decreasing glucagon released by the liver due to insulin resistance. It also delays gastric emptying, signaling fullness feelings and decreasing appetite.
How to Improve It
Eating high-fiber, lean protein, and foods high in unsaturated fats is the best way to naturally boost GLP-1 levels. Meals that include ingredients like lean eggs, nuts, avocados, whole grains, vegetables, and olive oil can leave you feeling full and satisfied. Improving any issues with constipation and diarrhea (irritable bowel syndrome) can also lead to consistent secretion of this hormone. You may also choose to discuss a prescription for GLP-1s (such as Saxenda or semaglutide—also known as Ozempic or Wegovy) with your medical weight loss provider in Spokane or your primary care provider.
Wrapping It All Up
