Yes they have oldbatty I’m a size 14 and though I aspire to a size 12, realistically I know I’m unlikely to lose those last few lbs.
I’d add something extra...when planning meals go for quite a bit of vegetables...anything except potatoes. I don’t mean don’t eat potatoes just do not count them as your veggies.
Portion wise for your main meal look at your hands.
The palm of your left hand is the size of your protein eg fish, meat, egg, cheese, etc. The four fingers of your left hand is your carbs. potatoes, rice, pasta, etc.
Then look your right hand and all of that should be your vegetables...2-3 different kinds if possible.
This is a sort of rough and ready guide.
Keep breakfast and lunch light, adding extra veg (eg tomatoes) where possible and a portion of fruit. And allow yourself a small treat mid afternoon.
If I’ve over indulged I miss breakfast the next day then back to normal. You won’t lose weight fast on this perhaps 1-2lbs a month, but hey ho! if only a lb a month that’s nearly a stone in a year. Slow and steady does it.
And move!
