Which Hormone is Keeping you Fat?   

It only takes one hormone to prevent weight loss! 


Why Men Gain Weight In Middle Age

It’s not uncommon for men, like women, to experience weight gain as they get older. In fact many men start to gain weight after the age of 40. This article will explain many of the reasons why.

Why Men Gain Weight In Middle Age

Men gain weight - Hormonal changes

While men experience fewer hormone changes than women, hormones are still a big factor when it comes to weight gain for men.

Testosterone levels drop which can make it difficult to hold onto muscle mass, lower energy levels and increase retention of body fat.

An estrogen imbalance may be causing your body to retain body fat. Estrogen dominance for men is when levels of the female reproductive hormone are higher in relation to testosterone levels. Higher estrogen levels can be caused by xenoestrogens (environmental estrogens), stress, alcohol and excess body fat. Or it could just be that testosterone levels have dropped while estrogen levels haven’t.

What causes male weigh gain after 40

Men weight gain - Less Activity

Men are less likely to be active as they get older. You may have become very busy with your family or with your career. Maybe you’ve moved to the suburbs which means that you are probably using your car more and walking or biking less. You are also probably spending less time at the park playing with your children on weekends. Pain and injuries may be preventing you from staying active. And weeknight sports are probably long forgotten.

If any of this sounds familiar it could explain how your activity levels have gradually dropped since you were younger.

Men weight gain - Other Lifestyle Factors

There are several other lifestyle factors that can contribute to weight gain in your forties.

Drinking excessive alcohol

While you may have cut back on alcohol consumption since your 20s, it may still be having a detrimental effect on your overall health and causing weight gain. Alcoholic beverages are calorie dense and can contribute to poor eating choices and raise estrogen levels.

High stress jobs

In your forties, you may be reaching new heights in your career, but the stress can adversely affect your weight and your overall health. You may be eating out more, especially convenience and take out foods, and have less time for any kind of exercise. And the stress of your job can lead to high cortisol levels. Stress can also zap your motivation to make changes.


Divorce can lead to emotional and stress eating, and more take out foods. Men who get divorced may drink more alcohol in the period after divorce or separation. And the stress of this life change can lead to higher cortisol levels and other health issues.

Men weight gain - Slowing metabolism

Your metabolism is the rate that your body burns calories. And this is often blamed for weight gain after 40. But for men most of the metabolic slow down can be attributed to other factors like less muscle, and less activity, stress, or hormonal imbalances.

Men weight gain - A feeling of inevitability

If you feel like you haven’t made any changes or you’re just too busy to make better choices you may feel that gaining weight in middle age is inevitable. But there are many choices you can make to make it less likely that you’ll gain weight.

Food choices that cause weight gain

Men weight gain - Food Choices

Men often gradually make poorer food choices as they get older. Some changes you might have made are:

  • Fewer family meals

  • More eating out or grabbing snacks from a vending machine

  • Highly restrictive fad diets in an attempt to lose the weight

  • Eating more processed foods

  • Fasting or going for a long time between meals

What you can do

Sometimes it seems like weight gain is inevitable when you get older, but it’s NOT and there are several things you can do:

  • Limit processed foods

  • Limit food and drinks that contain added sugar

  • Limit alcohol consumption

  • Eat enough protein to help maintain muscle

  • Start a strength training routine. Not only will this help to limit muscle loss, but it also helps to improve testosterone levels

  • Avoid strict dieting and fasting

  • Practice stress reduction activities

  • Get professional help
