Try moving snacks that are laying around the house and put them in a cupboard high up or low down, so they are not within easy reach. Replace with fruit on the sides in the kitchen and in a fruit bowl in your living area. You are more likely to eat healthy food if it is within easy reach. By having the bad snacks put away you are less likely to go and get them if fruit is on the side and to hand.
Remember
Persistence is what makes things happen!
