I'm just curious, have you considered just doing a calorie deficit diet with the walking/jogging? Lets say you're 6ft tall and weigh 245 pounds and you're exercising 2 times a week for 30-60 minutes each time. If you did a diet capping your calories at 2400 per day, you'd be losing 1 pound a week. If you capped it at 1900 calories per day, then you'd be dropping 2 pounds a week. You can still pretty much eat whatever the fuck you want, just have to make sure your calorie intake doesn't exceed those levels. (Though, I'd also recommend make sure your carb intake doesn't exceed 40 percent of your food. At 6ft, 245 pounds that would be 203 grams per day.)
I've lost 200 pounds in the last 23 months from literally just walking 1-2 times a week and not eating over 1700-1800 calories per day, man. Weight loss is definitely a gradual change that you have to work on with your mindset, change is never just an overnight thing. It can take months or years to really stick with something, it's just important that you keep trying until you eventually have a come to jesus moment. Just keep at it, dood.
