Hi, I was 95kg at the start of this year and I also tried calorie deficit for few weeks but soon found out it’s not very effective and counter productive. The problem with calorie deficit that you put all the weight back and it slows down your metabolism and growth hormone.
I switched to Intermittent Fasting on 25th Feb 21 and by Jun 21, I had lost my target weight of 20kg. Since the end of Jun, I have been maintaining my weight between 74-75 kg purely by doing daily intermittent fasting. I have fond IF very effective and would recommend it to you. Weight loss is only one of many benefits of IF. I do 16-18 hours fast on Mon to Fri, and on Sat/Sun, I still do around 14-15 hours fast.
