Does anyone else eat completely different things on any given day? For example, I can eat extremely healthily one day, and then the next day I can eat like a horse (a horse that really likes chocolate).
Today I ate:
Breakfast: 5 spoonfuls of Alpen with semi-skimmed milk, one glass of orange juice, 3/4 cup of sugarless tea (I was late, and cramming it all in. Not nice)
Lunch: 3 scoopfuls (as in ice-cream scoops) of mashed potato. One small chocolate muffin. One bottle diet coke.
Snack: Marks and Spencer's layered chocolate bar, around 250 calories. One can Fanta-Z (about 9 calories, I reckon).
Dinner: (in about 10 minutes) pasta with cheese.
I know there aren't any fruits/veg on there - I'm normally better - and normally I only eat one chocolate portion per day. But its what I felt comfy eating today. I tend to listen to my body i.e. if I have a craving I assume my body needs it and I eat it.
I've tried obsessing over everything I eat (which ends up with feeling guilty about eating anything and eating literally 800 calories per day) and I don't recommend it to anyone! The occasional chocolate bar or fizzy drink won't kill you, and a day without fruit isn't a disaster.
OP: if you don't want lunch, and you're maintaining a healthy, steady weight, and you have plenty of energy, don't eat lunch. A bit more fruit, maybe?
