Progesterone Weight Gain: Understanding Hormonal Imbalances

progesterone weight gain

Hormones are the chemical messengers of your body. They regulate everything from sleep cycles to menstrual periods, and they can also affect your weight. This article will explore how progesterone levels affect weight regulation for both men and women, as well as what you can do about it if you’re experiencing a hormonal imbalance.


What Is Progesterone?

Progesterone is one of the two main types of female hormones – estrogen being the other one – that regulates menstruation, pregnancy, ovulation, and fertility. It’s produced by both males and females in different quantities throughout their lifetime but is for females it’s primarily made by glands in the ovaries before her period starts each month (13). 

The average cycle duration for a woman is 28 days, or around 4 weeks (12). During the first two weeks of a woman’s cycle (before ovulation), estrogen levels are at their highest and she’ll experience heightened emotions and sex drive in addition to significant changes to her anatomy such as swelling breasts and preparing the uterus for pregnancy.

Around 14 days into a woman’s reproductive cycle, progesterone levels surge right before ovulation occurs when an egg is released from one of her ovaries. If this egg isn’t fertilized by sperm cells soon after ovulation, then progesterone levels subside after the second half of her menstrual cycle when her next period begins (12). If a pregnancy occurs, progesterone remains elevated and continues to rise.

This spike in progesterone is what causes positive pregnancy test results if a female becomes pregnant during a given month because it signals the body to stop menstruating and fulfill its role as a nurturing environment for a fertilized egg (15). 

When progesterone levels are balanced throughout both different parts of a woman’s cycle and throughout her entire life, they promote healthy weight regulation and the optimum function of other hormones (14). On the other hand, imbalances can lead to reproductive health problems as well as weight gain.

What Causes Progesterone Imbalances?

Progesterone can be thrown out of balance due to:

  • Stress
  • Illness
  • Changes in weight
  • Breastfeeding 
  • Menopause
  • Oral contraceptives (birth control pills)
  • Polycystic ovarian syndrome (PCOS) 
  • Obesity
  • Smoking cigarettes
  • Drinking too much alcohol
  • Eating sugar-laden foods excessively
  • A sedentary lifestyle

What Are The Signs Of Progesterone Imbalances?

Progesterone and estrogen complement and balance each other, so it is important that their levels in relation to one another are appropriate. Too little progesterone can cause estrogen dominance  (2). While estrogen plays a crucial role in PMS and menstruation, you don’t want your body to be flooded with it because that can lead to weight gain and other negative side effects such as:

  • Bloating 
  • Abdominal cramping 
  • Mood swings 
  • Headaches
  • Low libido
  • Fatigue
  • Insomnia 
  • Painful periods 
  • Irregular periods 
  • Heavy bleeding during your period 
  • Bleeding between cycles 
  • Tender breasts 
  • Fibroids 
  • Endometriosis

How Does Progesterone Affect Your Weight?

Hormonal imbalances resulting from abnormally low progesterone levels can lead to weight gain, though this is contingent on other factors that impact hormone receptors (10). Here are some of the ways in which low progesterone levels affect weight:

Low Progesterone May Increase Appetite

Hormones interact with each other in complex ways that can affect our appetite. For example, when you’re sleep-deprived (which tends to be another symptom of low progesterone), the hormone ghrelin increases along with cortisol and adrenaline; all three of these hormones stimulate your appetite (5).

High Levels Of Progesterone Cause Hyperinsulinemia

Both too much and too little progesterone can impair your body’s blood sugar regulation. When progesterone levels are high, it increases the amount of insulin present in the blood (9). Too much insulin causes your body to convert more sugar to fat. High insulin levels also cause you to feel hungry, which can lead to overeating (7).

Low Levels Of Progesterone Cause Carb Cravings

If you’re trying to lose weight, the last thing you need is for your body to be craving more carbs. Cravings usually happen when blood sugar levels drop, which is often due to excess cortisol. When progesterone levels are low, they cause an increase in the stress hormone cortisol. Cortisol then causes a decrease in blood sugar and an increase in food cravings (18).

Low Levels Of Progesterone May Cause Fatigue And Low Energy

Fatigue and lack of energy can lead to overeating, especially if we think we might feel better by eating some refined carbs or sugar. This vicious cycle makes it very difficult for people with low progesterone to lose weight. They’re also more likely to get discouraged and give up on their weight loss efforts because they’re too tired (and hungry) to keep going.

Low Progesterone Levels Prevent Normal Functioning Of Thyroid Hormones

Progesterone may have an effect on thyroid hormones (16). When progesterone levels are low, you might notice that you’re cold more often (despite having enough layers of clothing on) and your metabolism slows down; if thyroid hormone function decreases, so does our metabolic rate.

How To Balance Progesterone Levels Naturally

It is vital to understand that the body needs progesterone, but too much of it can lead to symptoms such as breast tenderness, abdominal discomfort, mood swings, and sleep issues. Not enough can lead to a lack of a menstrual period, infertility, and weight gain. So how does one balance progesterone levels naturally without disrupting the body’s delicate hormonal balance?

Here are some ways to go about it

Change Your Diet

Although no foods contain progesterone, the following foods can provide the environment needed to support your body to balance progesterone levels:

Increase Cruciferous Vegetables

Cruciferous vegetables are vegetables in the brassica family. They include broccoli, cauliflower, cabbage, kale, collards, and brussels sprouts. This is because they are high sources of nutrients that are beneficial to progesterone production.

Eat Magnesium-Rich Foods

Magnesium deficiency has been linked to low progesterone levels, so it is important to make sure you are getting enough magnesium in your daily diet. Magnesium rich foods include spinach, artichokes, whole grains, nuts and seeds.

Eat Anti-Inflammatory Foods

It may be helpful to eat anti-inflammatory foods that help reduce inflammation of the endometrium (uterus lining) which can lead to diminished progesterone production (4). Some ideal anti-inflammatory foods to eat include green leafy vegetables, omega 3 fatty acids from cold water fish, avocados, cherries, grapefruit juice, fresh basil leaves, and ginger.

Eat More Fiber

Increase your daily intake of dietary fiber. Good sources of dietary fiber include black beans, turnip greens, sweet potatoes, avocados, apples with the skin on, and whole grain products.

Take Vitamin Supplements

Progesterone can only be synthesized from the pregnenolone precursor molecule made by the body (3). Taking a vitamin supplement containing vitamins C and B6 along with magnesium might help the body to make more pregnenolone which then can be converted into progesterone. 

Other nutrients that may help promote normal  progesterone production include vitamin B6, zinc, magnesium, vitamin D3, omega 3 fatty acids from fish oil or algae, and L-arginine.

Get More Vitamin D

Vitamin D is produced naturally by the body when exposed to the sun’s ultraviolet light rays. A study found that vitamin D induces production of progesterone and estradiol (21). 

Maintain A Healthy Body Weight

Being overweight causes an increase in estrogen levels which lowers progesterone levels. It is important for women not to exceed their healthy weight range to maintain proper hormonal balance. Excess body fat also releases inflammatory chemicals that trigger the production of extra estrogen and cortisol, which further upsets the delicate hormonal balance (19).

Manage Stress

In extreme situations, stress can decrease progesterone levels to the point where ovulation does not take place (11). Stress management techniques such as yoga, meditation, deep breathing exercises or fun leisure activities are recommended. If stress is an ongoing issue for you, try seeing a therapist who can help you work through problems, thus reducing stress overall in your life.

Lower stress to reduce cortisol production which will also help your body produce progesterone more efficiently. 

Get Better Sleep

Studies have shown that women who sleep 5 hours or less per night have lower progesterone levels than those who get 7-8 hours of rest per night (17). This can lead to experiencing more hot flashes in menopause so be sure to get a good night’s rest.

Make sure you get enough sleep by going to bed before 11 PM so that melatonin is produced properly. 

Exercise More, But Not Too Much

Exercising for at least 20-30 minutes daily has been shown to boost progesterone levels but only in the absence of PMS. Exercising too much can lead to an increase in cortisol production and thus increase progesterone levels. Be sure not to overdo it when exercising or participating in sports activities as this can result in a hormonal imbalance that leads to fatigue and mood swings.
