In this article, I'm going to share the one lifestyle change that relieved my hot flashes and other symptoms during menopause: intermittent fasting. I was miserable with hot flashes day and night. It prevented me from sleeping. Then I started gaining weight rapidly. No amount of diet and exercise was helping. Then I noticed severe brain fog and mood swings. I made my family miserable. I was miserable. I couldn't keep living like this, but I didn't know what to do! Then I discovered intermittent fasting, and I couldn't believe how quickly it cured my hot flashes, insomnia, weight gain, and other menopause symptoms. Here is my story…







What is the best way to do intermittent fasting for menopause?

When I heard that intermittent fasting could help with my hot flashes, insomnia, and other menopause symptoms, I figured I had nothing to lose by trying it. There was nothing to buy and no rearranging my schedule to add another item to my to do list. This is how I organized my schedule:

  • I fasted for 20 hours each day and had an eating window of four hours. For example, I start fasting at 8:00 p.m. each evening. No eating or drinking other than water after 8:00 p.m.

  • I usually go to bed by 10:00 p.m. and wake up around 4:00 a.m.

  • I skip both breakfast and lunch.

  • At 4:00 p.m. I have a snack, usually plain yogurt topped with fruit and honey.

  • At 6:30pm I eat a high protein dinner. This is during my four hour eating window from 4:00 p.m. until 8:00 p.m.

  • After 8:00 p.m., I don't eat again until the next day at 4:00 p.m. This is my 20-hour fasting window.

    When I first started this 20:4 intermittent fasting routine, it relieved my hot flashes within three days. Within a week I was sleeping through the night. As the days passed, I noticed my other menopause symptoms began to disappear. Intermittent fasting was helping with my inflammation , which resolved my menopause symptoms. I couldn’t believe that it was this simple.





How can I get started on my intermittent fasting journey?

Starting the intermittent fasting journey is very simple, but changing up your routine isn't always easy. It takes some planning and a strong mindset to decide you won't eat or drink anything that contains calories for 20 hours and then stick to it. I'll be the first to admit that the first few days were hard. Not impossible, but hard. After two or three days, especially if you are beginning to feel relief from hot flashes or other menopause symptoms, you will be ALL IN on intermittent fasting. Then you can continue for as many days as works for you and your lifestyle. Intermittent fasting has become my lifestyle, making all things simpler:

  • No packing lunch or doing meal prep before work

  • No stopping at fast food restaurants

  • No spending money when I forget to pack lunch

  • No wondering what to make for breakfast

  • More time in the morning to read and drink coffee (plain, no cream or sugar)

  • No more paying premium prices for mediocre food on long trips

  • Save time on trips: no stopping for food, snacks, drinks, etc.

Once you see and feel the benefits intermittent fasting can bring to your life, it will be easy, enjoyable, and a healthy habit. After only three days my hot flashes stopped completely. So I continued to fast on most days, usually Monday through Friday when I'm at work. On the weekends or special occasions, I'm more relaxed. When you get invited to a special dinner or party, go and eat the cake, guilt free! 






More Benefits of Intermittent Fasting

Once I started intermittent fasting, my menopause symptoms went away within three days (incredible!), and I started noticing these benefits: 


  • Less puffiness

  • Clothes fitting better

  • Sleeping better

  • Weight loss (finally!)

  • No more hot flashes

  • No more night sweats

  • More energy

  • No more joint pain

  • Less irritable


I couldn't believe the results I was getting! Because this experiment was so successful, I still practice intermittent fasting for 20 hours daily with a four-hour eating window almost every day. My hot flashes and other menopause symptoms have never returned.
