The Benefits of Intermittent Fasting For Women Over 40

Regardless of age, Intermittent Fasting has been studied to help improve insulin sensitivity, increase gut health mechanisms and boost fat burning.(1)


However, one benefit that's particularly useful for women over 40 is the improved insulin sensitivity perk. As we age, insulin resistance (the opposite of insulin sensitivity) tends to go up. This is usually due to muscle loss and other hormonal changes. Especially if you have had a pregnancy in the past, there could be possible lingering effects of increased insulin resistance from the pregnancy.


Insulin resistance can make it difficult to achieve a weight loss goal. So if your goal is to lose weight, then one major step is to help improve insulin sensitivity.

How Long Should A Woman Over 40 Fast?

How long you should fast will depend on a few factors, such as:

  • if you're exercising

  • how intense you're exercising

  • if you're new to fasting

  • your protein needs

  • if you're recovering from an injury

  • if you're insulin resistant

Generally speaking, I never recommend fasts longer than 20 hours. Any longer than this and it's easy to run the risk of not getting adequate protein for the body's needs. And interestingly, as we age our protein needs go up, not down. As protein intake is required for maintaining the metabolism and helping to prevent osteoporosis in the future, this should not be sacrificed.


That being said, I've found a good fasting length that balances the perks of fasting with the perks of eating to range (for most people) between 14-16 hours per day. Although, as I mentioned this can change depending on your specific circumstances. You can checkout my free quiz to help you determine your ideal fasting length HERE.
