According to PhysicsDiet.com my Total Energy Expenditure is 2645 calories per day. To lose 2 pounds a week, which is what I am roughly aiming for, I need to eat 1000 calories fewer than this a day:

2 pounds of fat = 7000 calories
7000/7 days = 1000 calories

So 1645 calories a day.  This doesn’t seem insanely low, I just need to start counting how many I’m eating.  Today’s count was:

Breakfast
Nothing

Lunch
Can of Baxter’s Leek & Potato Soup – 186

Dinner
Co-operative Cajun chicken and red pepper rice – 450
Mango chutney – ~30
Muller Fruit Cornet strawberry yoghurt – 198

Total: 864 calories

Ah, only about half of what I should be eating!  This evening will be spent planning the rest of the week’s meals so I’m getting enough.
