best time to cut, imo since caloric intake should be lower than usual.
this provided we stay away from stuffing our mouths will food from ramadhan bazaar's the moment buka..lol

Just dont loose too much muscle mass while doing it..

imo workout like a beast stepping up intensity for a month or two before the fast, 3 weeks before fast start de-loading.

during fast let your body rest and occasionally lift 1-2 a week full body compound exercises with moderate weights ,moderate sets/reps.

lets face it, if you are going to fast you will be losing muscle mass. there's no way around it. dont stress out too much on that though, if you're fasting then your reasons are greater than the physical body rite?

just let your body detox and come back strong after the fast, if you've been training and eating with high intensity it should give your body a well deserved rest and detox.

intermittent fasting has been the hot topic of many youtube fitness channels recently. its a pretty interesting approach, however it allows for consumption of fluids throughout the fast unlike ramadhan fasting so i dont know if the same concepts can be applied.

Not too sure if the body would react the same way towards the calories put in during that 'window' if the body is dehydrated.
