I wonder how safe this is... Men's libido seems to increase when fasting, but women's disappears? Any fasting experts here? Here's a little poll I found on this subject: http://fastingforum.healthdivas.co.uk/viewtopic.php?f=8&t=17

Constructive and well informed answers please!

We typically stop eating by 10 or so. The next morning is bulletproof coffee and lunch sometime after 12 PM. Using the 10 windown for women, this easily fits. She has thrown in some 20 hour fasts as well with no ill effects and no signs or feelings of hunger.

Hi Matt, thanks for this! I have been reading about the bulletproof IF. DOes your wife stop eating at 8 pm? I would find that really hard as I work all day, then exercise in the evenings, get back home at around 9 pm! Thanks!

If you haven't noticed any ill effects (lethargy, weight gain, any excessive malaise and fatigue) you should be ok. If it is working for you, than by all means, keep it rock'in!

So does that mean that if you're going through a high stress period in your life, you shouldn't fast at all? I'm in the second year of a divorce and it's pretty stressful right now...I've been doing a little IF, nothing wild, just dinner around 6pm, brunch around 11 or 12...And I always break with high protein and fat...

Very true about the low stress as fasting is another stressor on the body.

I been researching upon women and fasting and can't make up my mind some women do well others don't, I noticed the ones that do fine are usually keto-adapted people. I am so interested because I want to know if it is something I should recommend my mother doing. Mom's blood pressure a little high, she is 51, 60 lbs overweight (she lost 30 already doing a ketogenic paleo). So my main concern is not to put undo stress on my mother body. Today she didn't eat for 17 hours because she had to fast for blood work this morning she got a slight headache. But she didn't do it on a low stress day...

There is so much research that needs to be done on fasting in general (especially among women). If you are fat adapted, I would recommend some n=1 experimentation to see how your body responds to it. What approach were you considering? A LeanGains approach (intermittent feeding) or more of a Eat Stop Eat protocol (24 hour fast once a week or so)? My wife seems to have responded well to a 14 hour fasting window followed by a 10 hour feeding window. However we are still in early stages of experimentation and the review research is so new or non-existant we are really on our own.

Some background on her: 28 y/o female, 5'4' 124 lbs. AM consumption of "Bulletproof Coffee" (high fat consisting of grass fed butter and MCT oil coupled with low toxin coffee), we have also used coconut oil in the coffee with similar effect. She is fat adapted and the exercise routine is heavy resistance training coupled with running and cycling (triathlon training currently). I would start with the 14/10 and chart progress and results from there. Definitely keep track of your results as they are needed in the community!

I do intermittent fasting on a daily basis. I have been doing this for a month or so now. I do have bulletproof coffee, which does not interrupt the fast, and do not eat until lunch time. I try to keep it no more than 14 hours, but I have gone 16-18. At 16-18 I am starving and the only reason I have not eaten is because my work schedule did not allow time. For women no more than 14 hours is suggested. I count from when I last ate the night before until I eat the following day. We tend to eat late, 9 pm or so.

Since I have been doing this my libido has not changed. I also have energy to do workouts fasted as well. If your body is fat adapted your energy levels should not drop.
