Intermittent Fasting Male Vs Female

Intermittent fasting is an effective weight loss plan that can completely overhaul your health and wellbeing, but everyone’s results are different. One person may lose more weight, while others drop more inches. Sometimes your progress will plateau as your metabolism has adjusted to your new eating schedule. 

There are a number of different factors that can impact how intermittent fasting will affect you, and one of the most prominent is your gender. Results may vary by male or female intermittent fasters, so let’s explore some of the reasons why, including benefits, key differences, and how to choose.

Benefits of Intermittent Fasting for Women

Intermittent fasting in women can help you lose weight. Initial studies suggest that it may lower bad cholesterol more in premenopausal women than post-menopausal women, but more studies are needed to support this claim. Overall, there are no major differences in weight loss, glucose levels, HDL cholesterol, and triglycerides in women based on age, which is a great sign! No matter your age, you can reap all the benefits of intermittent fasting. 

Pre-menopausal women may face changes in their menstrual cycle after intermittent fasting because fasting can impact their hormones. It may also impact your fertility, so consider your lifestyle before starting intermittent fasting.

Benefits of Intermittent Fasting for Men

Intermittent fasting for men is an effective weight-loss tool. It’s also used to help lower your blood sugar, improve your heart health, and so much more. Intermittent fasting can also trigger an increase in Luteinizing Hormone, which is partially responsible for testosterone production. The higher your LH levels, the bigger boost you’ll get in your testosterone levels.

As you lose weight, you don’t have to worry about losing muscle. Intermittent fasting in men can help improve their insulin resistance and reduce the risk of developing diabetes and heart disease. Intermittent fasting in men can help you look and feel healthier.

What are the Differences?

Initial studies suggest that men and women lose a similar amount of weight when they are intermittent fasting. Still, there are differences that may make intermittent fasting a better choice.

  • Hunger

Studies show that women reported feeling hungrier during intermittent fasting than men. They were exposed to the same study conditions and stimuli, but women responded more to these elements. That’s not necessarily a bad thing. It just means that it may take a little getting used to and more self-control at first to get used to fasting. 

  • Triglyceride build-up

During intermittent fasting, triglycerides will build up in your body, though, where is dependent on your gender. Studies show that they tend to build up in men’s livers and women’s muscles. At this point, the effect is unknown.  More research is needed to see if there could be potential downsides to this triglyceride build-up.   

  • Insulin Response

Intermittent fasting can have a huge impact on your insulin levels, but the jury is out just which sex benefits the most. A 2005 study suggested that the glucose response to eating was slightly impaired in women after fasting; however, their insulin response was unchanged. In this study, the male subjects faced a significant reduction in insulin response. Unfortunately, these results were flip-flopped in a study just two years later. Glucose levels in women were significantly lower after fasting. 

It’s hard to tell who will get the better response, but both men and women will see insulin and glucose benefits during intermittent fasting.

How to Choose?

Intermittent fasting is safe and effective for both men and women, so if you’re considering starting a plan, first identify what plan will work best for your lifestyle. Consult with a doctor if you are on medication, particularly those that require you to eat while taking them, before starting intermittent fasting.
