Advice or concerns I should have regarding my current fasting/OMAD/keto thing I’ve started doing

I recently just stumbled into it somehow.

During work week I already did intermittent fasting but I was still eating plenty of sugar and bread and stuff, so it clearly started to show weight wise.

So I started walking regularly, doing some body weight exercises (little by little increasing reps slowly just to make sure I continue doing them daily/ create the habit)

Then recently I decided to remove the sugars during the week and maybe some on weekends and I fell into this “routine” for myself of having a Keto OMAD and then 48hr fast.

So for example:

Monday: One meal in the evening (keto) after 7pm

Tuesday: fast

Wednesday: One meal in the evening (keto) after 7pm

Thursday: fast

Friday: One meal in the evening (keto) after 7pm

Saturday: eat whatever

Sunday: One meal in the evening (keto)

I feel good for the moment with this routine but I feel that on my OMAD days I may not be eating enough calories.

I am drinking water, and also sometimes coffee or tea but yeah.

I haven’t started to integrate any supplements or electrolytes yet either

So I guess any suggestions or advice you all may have, I would love to hear it!

Thanks!
