OK, if you want adjustments you could make:
Breakfast:
Graze bar (the small individual oat boosts at around 90 calories)
An Apple Not bad, if this is what suits you - you say you don't like breakfast, so have this mid morning. You could alternate with a banana.
Lunch:
A normal bag of McCoy’s crisps (lunch was very busy). Plan ahead to have a lunch which has protein and veg / salad in it. An egg, cheese or chicken sandwich on wholemeal bread, with carrot batons on the side, for example. Make at home or pick up on your way to work?
Dinner: McMuffin Fakeaway
2x warbutons breakfast muffins, 4x rashers of bacon, 2x McCain hash browns, 2x poached eggs . A better version would be poached eggs on a bed of spinach on wholemeal toast - frozen leaf spinach is easy to microwave - and a salad on the side, maybe including a chick pea salad? OR felafels with hummus in pita plus salad. OR a baked potato with tuna plus salad
Snack:
Fun size bag of mini eggs (the smallest size ones) Swap for a satsuma or 2 squares of dark chocolate.
Previous day:
Breakfast: Nothing If you can't do breakfast have a good mid morning snack as above. Banana, apple, chunk of cheese, carrot sticks, natural greek yogurt with berries, or a handful of nuts or nuts and raisins
Lunch: Nothing Have a good lunch with some protein and veg. Oat biscuits and cheese with cucumber sticks, a chicken drumstick, etc.
Dinner:
Grilled chicken with salad and pittas, onion rings and 2x slices of garlic bread Started off really well. Swap the onion rings or garlic bread for more salad
Snack: Fun size mini eggs Adjust as above. 2 squares of dark choc, or fresh strawberries or raspberries or blueberries are nice to pick at while you watch TV, Or grapes.
Good luck OP - it gets easier if you shop and prepare for healthier meals and get in the habit. A few aberrations - fine, don't give up, just get back on track without beating yourself up.
