Re Snacks, all the time you are calorie counting and staying within your calories great it's not a problem however once you reach your target weight and stop calorie counting or ease off a bit you're now in the habit of having 3 meals and 2 snacks a day and it is very easy to consume an extra 1000 calories over a day, a couple of 100 calories on each meal, a couple of extra biscuits at snack time and boom 1000 calories over There is a reason people have to keep going back on diets. Also 80/20 isn't confined to 80% of meals 20% snacks, it's 80% of food consumed should be healthy, 20% treats, for me thats a bowl of porridge wih golden syrup and some cream or a couple of slices of toast with poached eggs and Avo but on 1 of the toast I put nutella on. I dont have 3 healthy meals and then an unhealthy snack.
