Question about whey protein and IF

Hi, I weigh 170kg (374 lbs), down 20kg since june. I am doing 20:4 IF. However, due to a change in my job, i cant go to the gym and schedule my intake of whey protein (my primary source of protein as I am a vegetarian), during my eating hours. I take protein to limit extra loose skin and replace fat with muscle. If I take protein with water during fasting period does it break my fast or if I take it during my new eating period (typically 4-5 hours after gym), will it have the same effect to limit my loose skin in arms and legs? via /r/intermittentfasting https://ift.tt/qWQuaNX https://ift.tt/jRKVSWb
