I lost 3 stone with SW late last year/ beginning of this. I found it handy to have a plan of what I was going to eat when, recognising my weak moments - I find the getting to dinner time difficult to - so, maybe something like:
Breakfast - 3 egg omelette, with Quinn sausage, mushrooms, tomatoes, tea.
10am - Alpen light bar, banana, tea
Lunch - Jacket spud,beans, cottage cheese, salad with light dressing,
5pm ish - bowl of cashew nuts and grapes or Alpen Light bar. Or something from syns. I usually had my syns here.
Dinner - pasta, veg sauce, Mullerlight, fruit
I tried to have some standard meals with no syns (spud, beans, cottAGe cheese / veg chilli and rice / veg sauce and pasta / omelette etc) and also some packed lunch ideas (Tuna salad/ soup and Babybels/home made low dat hummous and veg sticks ) so I could be prepared for most situations.
