Intermittent fasting for young 29 year old

Hi. I had a skinny fat body which has now turned to lean muscular. I am from a tropical country in Asia but have moved to Sweden in Stockholm. Dr. Berg's videos helped me a lot. In the beginning, I was skeptical and was double-checking all the information. Now, I do not take any vitamin supplements, have gained muscles, my fat % is 14 (down from 21, measured by Xiaomi weighing machine.

Overall, I feel better both physically, psychologically in the harsh-dark winter months of Stockholm.
