In the past I’ve lost weight by initially working out what a calorie deficit would be, then having several options of breakfast , lunch and dinner that fit this. Then only eating this.
got a bit boring, but worked and I didn’t have to ‘count’ calories every day.
example -
breakfast is a package of oat so simple (it’s pre measured so no faffing, just 1 packet)
lunch is 1 small tin tuna, handful of cherry tomato’s and other crunchy veg, 2 corn cakes.
dinner is a chicken breast, a small sweet potato, half the plate is either veg or salad.
no snacks other than crunchy veg (have this pre chopped in the fridge)
alcohol only on one night per week, few glasses wine max.
treats on one night per week, pre portioned (like 1 small bag crisps or bar of chocolate).
it might help to work out where your calories are coming from , big meals or biscuits or picking at kids leftovers etc. then try and eliminate this and just stick to your pre planned meals.
