Introduction

Weight gain can be annoying and frustrating, especially when it seems to happen for no particular reason. If you’re eating well and staying active but still gaining weight or you’re struggling to lose it, you could be experiencing the signs of hormonal weight gain. Basically, your hormones are the culprit.

Your hormones regulate everything from metabolism to appetite, fat storage, and even your energy levels. When they fall out of balance, what you get is stubborn fat accumulation, especially around the belly, hips, and thighs. In this article, we’ll explore the common hormonal causes of weight gain, the signs to watch out for, and the best natural ways to restore balance.

What Causes Hormonal Weight Gain?

Hormonal weight gain occurs when imbalances in hormones disrupt metabolism, appetite, and fat storage, leading to weight gain. Let’s look at the common hormonal imbalance that can cause a drastic weight gain.

Common Hormonal Imbalances Linked to Weight Gain

Some hormones directly affect weight regulation and if any of these hormones go a bit haywire, weight gain automatically follows. These hormones include:

  • Leptin (Hunger Hormone): Leptin resistance happens when your brain doesn’t get the message to stop eating and so, this leads to persistent cravings and overeating. If it’s not in order, then you’re going to gain some weight from overeating.
  • Estrogen & Progesterone: An imbalance between these hormones can cause weight gain around the hips, thighs, and lower belly.
  • Insulin (Blood Sugar Regulator): Insulin resistance makes it harder for the body to process sugar, leading to weight gain and an increased risk of diabetes.
  • Cortisol (Stress Hormone): Chronic stress leads to elevated cortisol, which promotes fat storage—especially around the abdomen.
  • Thyroid Hormones (T3 & T4): Hypothyroidism slows metabolism and increases water retention, causing sudden and unexplained weight gain.
  • Ghrelin( Another hunger hormone):  This hormone is the opposite of leptin because it stimulates your appetite. If you have high ghrelin levels then you might overeat and gain some weight.

 

The action of these hormones plays a direct role in your weight regulation, and if they are out of line even for a bit, you’re likely to gain weight.

7 Key Signs Your Weight Gain Is Hormonal

Let’s say you’ve gained some weight and you’re wondering if it’s just a sign of good living or if there’s a deeper issue at hand.

If you’re gaining weight it doesn’t necessarily mean that it’s a sign, because other factors can affect your weight. So, how do you confirm that those signs are actually signs of hormonal weight gain?

In this section, we discuss the signs of hormonal weight gain and what hormones cause those particular signs.

Stubborn Belly Fat (Cortisol & Insulin)

If you’re storing excess fat around your midsection despite healthy eating and exercise, cortisol and insulin imbalances may be to blame. Chronic stress triggers cortisol, which signals your body to store fat around the belly. High insulin levels due to insulin resistance prevent fat from being burned for energy.

Sudden Weight Gain (Thyroid Issues):

Unexplained, rapid weight gain, especially if it’s accompanied by fatigue, cold intolerance, and dry skin, could signal hypothyroidism. When your thyroid is underactive, your metabolism slows down, leading to weight gain.

Constant Cravings (Leptin Resistance)

Leptin is the hormone that tells your brain when you’re full. If you’re always hungry or craving sugary foods, you may have leptin resistance meaning your brain isn’t getting the “stop eating” signal.

Constant Cravings (Leptin Resistance

Are you always feeling exhausted even after a full night’s rest? This could be due to low thyroid function or adrenal fatigue, both of which contribute to weight gain.

Weight Gain Around Hips & Thighs (Estrogen Dominance):

If you notice weight gain primarily in your hips, thighs, and lower belly, estrogen dominance could be the issue. Excess estrogen leads to fat storage in these areas and can also cause bloating and mood

Difficulty Losing Weight (PCOS & Insulin Resistance):

If no amount of dieting or exercise seems to work, PCOS (Polycystic Ovary Syndrome) or insulin resistance might be interfering with your body’s ability to burn fat.

Mood Swings & Water Retention (Progesterone Imbalance

Low progesterone levels can lead to bloating, water retention, irritability, and emotional eating—factors that contribute to weight gain.

Experiencing these signs, wait, don’t panic yet. Confirm first if that’s what it is.

How to Confirm Hormonal Weight Gain

if you really want to confirm if your weight gain is hormonal or not? then, we advise you visit a doctor. Explain your concerns to tem and carry out the following lab tests.

Lab Tests to Ask Your Doctor For

The best way to confirm is to take a test. Talk to your doctor about your concerns and ask him for a lab test. Some of the tests you can take are:

  • A test to check your cortisol levels (saliva or blood test)
  • Fasting insulin & glucose test (for insulin resistance)
  • Thyroid function tests (TSH, Free T3, Free T4)
  • Estrogen, progesterone & testosterone levels
  • Leptin & ghrelin levels test

 

If you take these tests after consulting your doctor and it turns out that you do have hormonal issues, then the next section discusses the steps you should follow to get better.

What to Do Next: Balancing Hormones Naturally

If you’re done taking these tests and you’ve confirmed that you indeed are gaining weight and that it’s due to your hormone imbalance, there are steps that you can take to balance those hormones naturally. Some of these steps include:

  • Follow a hormone-friendly diet: Eat whole, unprocessed foods. Prioritize protein, healthy fats, and fibre. Avoid refined sugars and excessive carbs.
  • Exercise regularly: Strength training helps with insulin sensitivity. Moderate cardio supports adrenal and thyroid health.
  • Reduce stress: We know this one’s a bit hard but try to reduce your stress. You could try mindfulness, deep breathing, and quality sleep.
  • Support gut health: A healthy gut microbiome is crucial for hormone regulation. You’d be surprised by the connection between your gut health and hormones.
  • Consider targeted supplements: Magnesium, omega-3s, and adaptogens can support hormone balance.

Try out these tips if you’ve been wondering how to fix your hormonal weight gain and balance your hormones.
