main part is still my eating habits which i'm trying to change mainly as well, working out is just like a side thing, I started with only 5 minutes a day because i didn't want to overwork my body right from the beginning with like half an hour of a workout which I know is impossible for me in my current state, i'm doing 10 minutes now, working my way up to 30 minutes, adding like 5 minutes to it every week.
I did lose around 20kg once in a month like 2 years ago but what I did wrong was that I was working out every day and halfway starved myself which ended up in me gaining the same amount back with a bit extra and i'm trying to not repeat this mistake
