My first 3 day water fast.

Hello All!

I plan on doing my first 3 day water fast starting tomorrow.

Would love some advice. I am 6FT and weigh roughly 290lbs. I'm doing it mostly for fat loss. I am quite worried about loose skin though. Will that be a thing with my current weight? Will I still be able to weight lift during my fasting period. I ordered some fasting electrolyte capsules to take during my fast. Please let me know if I need to know anything else.
