cheeky, you can't skip the exercise, ok, for now maybe until you gain more energy right?
5 - 6 small meals a day is the better way to go, but depends on what your 3 meals consist of, want to share?
You know the 5 veg, 3 fruit, lots of water, low fat meats/ like chicken or fish, 200gms max of red meat and only twice a week rules, no butter, no cream, no mayo, ranch dressings, ahhhhh...
Replaced with soya and lemon, as a dressing, or tzasiki no fat, or, white wine as your sauce...
Then the in-between ones,
handleful of nuts,
celery sticks, carrot sticks, capsicum ( bell pepper) sticks, mushrooms cut
a small tub no fat yoghurt
handful of berries
egg white omlettes instead of the yolk,
wholemeal breads instead of white
are other things to consider,
haha good luck, no seriously, you can do it.
