My frame of mind about my diet

Iv hidden away from diets practical my hole life. Saddly i had a massive wake up call the end of last year my dad had a massive heart attack and we almost lost him at the age of only 53. I took a step back and took a hard long look at my life and the reality that i was going down the same road hit me in the face. So i started to diet to shift the extra weight and iv stopped smoking. At the end of the day this is my body there is only me can control what i put in my body i will be happier after this
