I build in an afternoon snack to fend of pre-dinner grab-and-binge.
My day when losing about 1lb a week:
Breakfast: grains / oat bran / all bran / some linseed stuff / 1spoon f/fat Greek yog and froz blueberries (maybe apple and or banana)
Lunch: 1 slice of wholemeal toast with soup or egg or tinned mackerel or sardines or cottage cheese or avocado, plus salad (including pulses if the soup or toast topping was protein light)
Snack: e.g 2 oatcake biscuits with cottage cheese and some carrot batons, cherry toms or cucumber / satsuma plus 30g cheese / small mug of s-skim milk with cocoa powder (no sugar) and an apple
Dinner: normal meal but be realistic about portion size. bigger portions of veg, smaller portions of carbs, avoid deep fried. Couple of squares of dark choc.
Luckily I love v dark choc , and cottage cheese. (Longley Farm, but it is expensive compared to Lidl deluxe version)
