I changed my diet and I've not looked back since. You feel better, you look better. I cut out a lot of the stuff I shouldn't have been eating and that was primarily meat, dairy, wheat, sugar - those were the four main things. ... Once you get into a pattern I've found it quite enjoyable. It has helped me sleep and I wake up feeling less tired. I noticed a massive difference in how I felt in about a week. I have more energy and focus and it wasn't difficult. I don't like to use the word diet because that's the reason I never went on a diet before - the word diet makes me miserable.
