i wanna start an exercise and diet regimen like i used to .

Dont diet. Theres no such thing as a "diet" imo. Your body needs vital nutrients mentally and for physical activity. Just eat smaller meals with less fat and sugar. Replace rubbish fats with healthier ones like coconut oil for example and if u dont have a gym near u then just walk do a few squats or even buy a cheap set of kettle wieghts. Theres so much u can do with them. You dont have to go bang at it. 3 times a week maybe. I need to get back into it again myself. Think this crap British weather gives u S A D lol. Need some more vit D. 😊 Good luck however u decide to do it.
