Hi there, (nor for people with eating problems, ok):
Seems we are somehow similar. Although this is still a normal BMI, this is what I did (1.75 - 78 KG) in 2018.
1) Once I went to the gym and took 7,5 KG in each hand and walked around, just to make myself clear how much "additional, non used weight" my body carries every day. Shock.
2) From one day to the other, I started to abstain from using the car whenever possible (I had a car at this time) and walked.
3) I did Nordic walking 3 hours every day (late afternoon, 20.000-25.000 steps) always with my sweat jacket (was in summer), sticks and 1 KG weight at each hand.
4) I went to the gym every day (although it was only 30 minutes)
5) I gave up eating for exactly 64 days and only lived by self-pressed juice (oranges, tomatoes, cucumber - all mixed with water) and I drank a lot of tea. (I bought a really good machine for 200 EUR or so).
6) I made Judo three times a week.
Within 64 days I went from 78 to 62 KG - but not only losing weight, - I built up muscles as well. Was really ok.
But it's funny - while in Sudan and Ethiopia you lose weight without even realizing it, in other countries you put on weight (somehow automatically...). However, never forget, that the body needs a small dose of sugar (honey in the tea) and salt (with tomato water) to function. Otherwise you will lose all power.
Ever since it has become an annual "ritual" to abstain from food for 3 months and to live on fresh pressed fruit or vegetable juice only. And it feels great. For 2025 - I will start on the 1st February until the end of April. Then again 4 - 8 weeks vacation in Africa (and you will not gain weight here - or everybody will ask you "where do you get your food".
