I've been doing intermittent fasting for about a year--it seems to work for me because I struggle with controlling portion sizes. Mon/Wed of every week I limit caloric intake severely--I skip all meals and snack on olives, pickles, maybe a small amount of avacado in the evening along with a couple of La Croix. Not sure why olives/pickles, other than I wanted to keep the fasting foods keto-friendly. Other than that, I used to chew a lot of gum during fasting, but have since stopped because I'm not sure what exactly "sugar alcohol" is doing to my body.

It has worked out well for me. I started at 230 in June and hit my baseline of low 190's in mid-November. I've been there since doing the 2-day fast. It is not too bad so long as you can stay busy, although it does really affect my mood on those fast days. It has helped my mountain/road biking immensely.

Just wanted to share my experiences...if anyone has other recommendations for fasting days, please share.
