Help! 17.5 hrs into my first 36 hr fast

I [early 30s F] first started keto and fasting 5 years ago and have been off and on ever since.

My longest fast to date was 27 hours, but usually I stick to somewhere between 16 and 23 depending on the time of the month.

We recently returned to a low carb way of eating after way too long back on the standard American diet (SAD). Last night, we had carb-heavy food out with my parents, and I woke up feeling bloated and having joint pain, which was the first time we ate that way since getting back on track. It was an excellent reminder of why I prefer fasting and keto/low carb over the SAD.

Today, I decided I should use a 36 hour fast to quickly work through the carbs and allow my joints time to heal after being inflamed.

I was doing great and just hit the 17.5 hour mark when my husband ate lunch. Now I’m feeling grumpy and a little shakey.

The fact that I was totally fine up until he ate makes me think that it’s more mental than my body actually needing to eat, especially since I do 20+ hours fairly regularly.

I’ve wanted to break into ADF for months but always run into this same issue - when he eats, i want to. Even if I’m in a different room, smelling the food makes me want some, too.

I broke out some bone broth to use as a crutch to help me continue my fast but am wondering if anyone has any additional advice. I suffer from PCOS and other hormonal issues and ADF would be so fantastic for me. I also struggle to lose weight and keto/shorter fasts aren’t as impactful as I think a longer fast would be for my hormones.
