what type of fasting will help preserve the most amount of muscle. Please help

ive been bulking hard since the summer, currently at 17% bodyfat. my goal is to get to 12% by summer. i want to cut by fasting. I've never done a cut this way, usually, I've done a calorie-restricted cut in the past. has anyone done it like this? and if so which fasting method should i use to preserve the most amount of muscle? approximately how long will it take? I've done many fast in the past both dry and water, but never for weight loss. height-6'0 weight-215 bodyfat-17% goal-12%

Answer

I will do same, I will do alternate day fasting, I will do weights on the eating day and low cardio on the fasting day, I will add ice baths on the fasting days

I will eat keto mostly salad and meat.

I am pretty sure this will work

Answer

What is your lifting schedule? Muscle retention is very dependent on continued use. Try to stick to your current lifting schedule and have a very high protein meal within 24 hours of every gym sesh. Those meals are non-negotiable. With that constraint, do you still have many options for a fasting schedule?
