I try protein diet where I consume more protein like meat, chicken and egg plus some vege. low on carb and cut off sugar. I cut 4kg from 105 to 101 in 2 weeks. I also do intermitten fasting for 16 hours. So far this diet work for me and I dont feel tired.

The hard part is to cut sugar and try avoid cheat day. Coz it easy to bounce back once you stop diet
