i was in the V1 group when this started back in 2009, updating what happened 15 years later.

1. I do regain some weight but never back to the peak of 115kg
2. my lowest weight was at 83kg but it was not sustainable and i am feeling lethargic all the time
3. I am maintaining my weight around 88kg, still at BMI of 28 but I target to lose about 3-4kg more
4. I felt great this round because I am losing weight slowly, about 1kg / month.
5. I have tried extreme diet such as keto but it does not works for me because I still want to live like a normal person traveling and not constanly worrying about food
6. I am started to add in weighted exercise it helps to tone up my body, i do looked leaner but the needle on the weighing scale does not really reflect that.
7. Cardio is good but too much of it does little to your bodyweight. I have done long distance swimming (>10km) or 100km trail running, or long hours of hiking.
8. watching what you eat is more important, learn to study food labels, understand what you are eating. I do eat unhealthy snacks or even sweets but I know what is going into my body
9. Unfortunately for today's lifestyle change with minimal movement around and more food availability, body weight management become a continuous effort, no point to fuss about a sudden spike weight, we look at the long term.
10. Sleep enough and drink enough
11. cut alcohol consumption when necessary because it is always associated with junk calories and unhealthy finger food

Good luck guys
