Extended Fasting / Working Out

(Katie the Quiche Scoffing Stick Ninja ) #1

Is there anything wrong with doing two extended fasts per week, and upon breaking the fast on the third day over the course of a few hours, eating maximum calories as possible up to 2000 and then working out?

For example
Monday 3:00pm begin fast
Wednesday Lunch time 12:00 eat predominately protein, low fat, calorie dense meal up to 2000 calories. An hour or so later do a heavy lifting session.
Thursday - Eat an OMAD at 3pm, begin fasting again until Friday
Friday Lunch time 12:00, repeat of Wednesday
Saturday Feasting Day
Sunday OMAD
Monday Repeat

Dr. Fung and Megan Ramos caution against fasting too long or too often. Here is Megan’s presentation to Low-Carb Breckenridge 2018. In it, she deals with some issues raised by Dr. Phinney at the conference and talks about why and when to fast as well as how to do it safely:

It depends on your goals. I have been doing three 36-hour fasts per week and enjoy it. It has worked well for me. I also have been doing one 132-hour fast per month (which overlaps the 36-hour fats). Once a quarter, I do a 168-hour fast instead of the 132-hour fast. I just do what feels good. If I am overly hungry, I’ll break the fast.

Megan and IDM have had patients doing a 5-day fast every week. I think this is usually therapeutic though, and not for weight loss. I do all of this for health, not weight loss. We need to stop thinking about how many pounds we have left to lose.
