I find 1200 actually pretty easy, as Aunt says skipping breakfast makes it even easier but isn’t for everyone.
Some days I’m really extra hungry so I have plain porridge made with mainly water and a dash of milk, with some fruit on top. Comes out under 200 calories. Nature valley granola bars are 200 cals a pack and I might have these as a breakfast if I’m on the go.
Lunch is typically salad with boiled egg, ham or tuna. No carbs. A big bowl including lettuce, carrot, pepper, cucumber, tomato, beetroot & sweetcorn plus the protein is 300 calories. Soup is also a huge bowl for around 300 calories. Biggish jacket potato & beans is 400ish.
If I need a snack in the afternoon it will be breadsticks or fruit or a piece of chicken. Up to 100 cals.
Then evening meal I have 600-900 calories depending on what else I had and that means I can eat a proper meal of pretty much anything I fancy. So Spag Bol, curry, stew, whatever. I also often have 0% Greek young with fruit or I like those dried fruit shots that have 95 calories and have some choc pieces in, they feel like a nice treat. And curly wurlies are amazing 118 calories and take ages to eat.
If I’ve not got many calories left for dinner I like aunt Bessie’s carrot & swede mash it’s lovely with fried eggs on top and you can have have 1/2 the bag (frozen bags are 500g) for 90 cals. Use it to top a cottage pie or serve it with roast dinner instead of spuds, it cuts calories quite a lot.
Good luck!
