>>20488884I would try to fix yourself in 1 year.
Firstly, I would start going to the gym and lifting. Start eating better with more protein, but don't focus on losing the weight yet. Don't try calorie restricting. We don't want you failing because you're trying to do too much. Lift weights 3 days a week. Full body workouts will work for absolute beginners like yourself.
After 3 months you will have put on significant muscle mass as your body will be very responsive to the new exercise (newbie gains). Some of your fat will have turned into muscle but you will still be the same weight as you were before and you will still be fat. You will look significantly better, but still a sad wretch.
Next, you want to lose weight for 3 or 4 months. Use an online calculator to give you an estimate of your maintenance calories and just go about 500 calories under that each day. Track everything you eat meticulously. For most people, this will be harder than training. While you're doing this, continue to work out 3 days a week. Try to eat mostly clean foods and find things you like eating that are low calorie. For me, I like the Yoplait zero sugar yoghurt as a snack - it's very low calorie. Protein shakes. Chicken breast with hot sauce on a wrap. You should lose about 1 kg a week if you do this correctly.
If you've done this first 6 months right, you will already look like a respectable person at this point. After this, I would start eating at your maintenance rate again (which will feel great) and start going to gym 4 or 5 days a week in order to pack on muscle and body transition. You will probably want to switch to a push-pull-legs type program.
I went from 90kg to 76kg in a 3/4 month period doing something like this. I am 5'10" and, if I had to guess, looked very slightly less wretched than you do when I began fixing myself up at 25 years old. It will take you about 6 months of effort to look respectable and about a year to start looking fit/athletic.
