In past 100 days I was on a 300 calorie deficit. Lifted 6 days a week. Cheated <4 meals in 100 days.

Weight dropped from 100kgs(220lbs, >30%bf) to 78kgs(approx 172lbs ~17%bf) I have retained loose skin on my chest and belly. Chest is ok I will bulk up and tighten it. But the skin on belly is scaring me.

Can anyone here give me any suggestions and share their experiences.
