Are Leptin Resistance and Insulin Resistance Related?

Leptin Resistance vs. Insulin Resistance 

Leptin and insulin are two hormones that play a crucial role in regulating energy balance and metabolism in the human body.  Fat cells produce leptin and leptin helps to regulate appetite, while the pancreas produces insulin and helps to regulate blood sugar levels. However, in midlife women, these hormones can become dysregulated, leading to leptin resistance and insulin resistance. In this blog, we will explore how these two conditions are related and what can be done to manage them.

What is Leptin Resistance?

Leptin resistance occurs when the body becomes insensitive to the effects of leptin. Unfortunately, this leads to an increase in appetite and a decrease in energy expenditure. This can lead to overeating, weight gain, and obesity. Leptin resistance is particularly common in midlife women. They tend to have higher leptin levels due to increased body fat.

What is Insulin Resistance?

Insulin resistance occurs when the body becomes less responsive to the effects of insulin. This leads to elevated blood sugar levels. Insulin resistance is a precursor to type 2 diabetes associated with obesity, high blood pressure, and other health problems. Like leptin resistance, insulin resistance is also common in middle-aged women.

How are Leptin Resistance and Insulin Resistance Related?

Leptin and insulin resistance are closely linked, as they both involve dysregulation of the body’s energy balance. When the body becomes resistant to the effects of leptin, it can also become resistant to the effects of insulin. This is because both hormones signal the body to store or burn energy, and when one is dysregulated, the other can also be affected.

Studies show that women with leptin resistance are more likely to develop insulin resistance and vice versa. This suggests that these two conditions may share common underlying mechanisms, such as inflammation and oxidative stress.

Does Being Overweight Mean I’m Leptin Resistant?

Not all overweight women are leptin resistant, although leptin resistance is more common in women with extra pounds. Leptin resistance may develop in individuals with a high body mass index (BMI) due to chronic exposure to high leptin levels, which occurs in obesity. However, not all overweight individuals become leptin resistant, and some individuals develop leptin resistance due to factors such as genetics or inflammation.

It’s important to note that obesity is a complex condition that can have multiple causes, including genetic factors, lifestyle habits, and environmental factors. Therefore, the relationship between obesity and leptin resistance is not always straightforward. However, research suggests that individuals who are overweight are more likely to have leptin resistance, which can contribute to the development of other metabolic disorders, such as insulin resistance and type 2 diabetes.

What Can Be Done to Manage Leptin and Insulin Resistance in Midlife Women?

Managing leptin and insulin resistance requires a comprehensive approach that involves lifestyle changes, such as diet and exercise, as well as medical interventions.

Dietary Changes

Midlife women with leptin and insulin resistance should focus on a balanced diet low in processed foods and high in fiber, protein, and healthy fats. This helps to reduce inflammation and oxidative stress, which are common contributors to these conditions. Foods that are high in antioxidants, such as fruits, vegetables, and whole grains, can also help to improve insulin and leptin sensitivity.


A sedentary, stressful lifestyle is the perfect storm for leptin resistance, so get moving! Regular exercise can help improve insulin sensitivity and reduce inflammation, which can also help improve leptin sensitivity. This does not mean you have to go to a gym! Many forms of movement are free and fun. Midlife women should aim to get at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, cycling, or swimming. In addition, weight training helps muscles use glucose more effectively and helps maintain bone and muscle health.

Supplements that Increase Sensitivity to Leptin and/or Insulin

  1. Berberine (lowers blood sugar and is as effective as metformin)
  2. Omega-3 fatty acids and fiber (this product has both and lowers leptin and increases adiponectin))
  3. Myo-Inositol (lowers insulin and leptin levels)
  4. Chromium (controls blood sugar)
  5. Alpha lipoic acid (lowers blood sugar)

Medical interventions

Medications may sometimes be needed to manage leptin and insulin resistance. For example, metformin is commonly used to treat insulin resistance and may also improve leptin sensitivity. 


Leptin resistance and insulin resistance are two common conditions that affect midlife women. These conditions are closely linked, and managing one can help to improve the other. Lifestyle changes, such as diet and exercise, are important for managing these conditions, but medical interventions may also be needed in some cases.
