One thing I’ve realized while living low carb that it is beneficial to continually optimize and adapt the lifestyle to fit my busy life, changing goals and family responsibilities.
I believe you should consider rethinking that as well, because your current work and workout schedule is not a good fit for OMAD, especially in terms of family time as well as the time to actually enjoy sitting down and having a meal.
If I were you, I’d consider doing OMAD on weekends and doing regular keto and IF during the week. It might give you more flexibility to achieve everything you need to do. And schedule your weekend workout close to your meal time.
I also believe that you are OMAD if you do all of your eating in 2-3 hours. I even consider 20/4 as OMAD. Trying to stuff it all down your gullet in one hour is not a good way to live your life and enjoy your meals.
I’ve done 23/1 for 6-8 weeks in the past, and it was productive for me in terms of losing weight, but as I upped my physical activity and got more hungry, I decided that upping calories and eating when hungry was going to be more beneficial for me long term.
