Good luck on your weight loss, man. The main thing with weight loss is calories in/calories out. I would calculate your daily calorie requirements and just cut that by 900-1000, without going under 1200 calories a day at least. Walking also is good to burn extra calories and build muscle, so do that when you can obviously. I've lost 86 kilograms in the last 17 months just by counting calories, fasting for 17-18 hours a day (That's also just to make my stomach feel better/healthier overall) and going on a walk once or twice a week. Just stick with it and you'll be dropping weight in no time, dood.
Damn, nice progress!
Thanks, dood <3
