I'm on Optifast 800 calorie-a-day for three weeks. The first week went fine. I feel like exercising for the next 2 weeks until surgery day. Is there any risks involved by exercising while on this diet?

Thanks.

The only risk is going all out and then getting hypoglycemic - 800 calories is not a lot. So I would stick to stuff that's more low-impact like walking or swimming. Intense workouts can make you quite hungry, which may make sticking to the diet more challenging!

Thanks for the good point. But this makes me wonder now, because 800 calories is what I was expecting to maintain post op. AFAIK, most sleevers eat between 700-1100 calories a day.

You are so lucky that you only have to do for 3 weeks. I am into week 2 of a 7 week pre-op diet.

It will be much harder to do pre-op as you still have a large stomach and you still get the hunger hormone. Yes, you can exercise, it's never a bad idea to get used to doing this now. But, keep it lighter because you will def get hungry very easy.

Post op you can deal with the lower calories, you won't be hungry probably ever if anything. That is a blessing from the surgery you have chosen! Good luck to you!! You can do anything you really put your mind to. PS I workout a lot - and I get in anywhere from 1,000 to 1,400 per day on these days. I only eat less on days I don't workout.

Thank you so much for the advice. I think I'm going to stick with walking for now and maybe some light weight lifting.
