30yo white male, overweight and obese most of my life. Adult life constantly between 240-290lbs, not the best of diets. If I were to make significant, lasting dietary, lifestyle, and exercise related changes, lose both weight and fat, add muscle, and overall get into a healthy weight/BMI and maintain i while continuing to eat better and exercise often....would there be any reason at such a you g age to worry about there being any permanent damage from the obesity? Whether heart/artery related or anything else, could there be unfoxable things present? How likely?
