Breakfast: oatmeal with a dash of maple syrup
Dinner: baked cabbage, which was really pretty awesome. I'm definitely going to make this again. The cabbage was very tender and surprisingly sweet.
I ended up eating half a head of cabbage during the course of the evening. According to this website, a whole head of cabbage contains 290 calories. This website helpfully adds that there are 4 calories in one leaf, but then goes on to list other more useful measurements. I think mine was a large (7" diameter) cabbage, which contains a grand total of 300 calories.
One cup of boiled lentils contains 230 calories. I may have eaten a cup. I was kind of in a hurry to get to work, so I didn't have time to eat too much lunch.
Oatmeal is a bit more challenging to figure out (also, I've gotten way off topic from allergies here.. ). A 1 cup serving contains 147 calories. But is that 1 cup before or after cooking? It must be after cooking because 1 cup uncooked oatmeal would make at least 1.5 cups cooked... which would require a really large cereal bowl. I started with 2/3 cup, so I probably ended up with nearly a cup of cooked oatmeal. I probably added about 100 calories worth of maple syrup, based on the info on the back of the bottle.
This gives me a calorie count of 637 for yesterday. The weird thing is that I wasn't hungry the whole day, except for right before dinner. Apparently hypoallergenic diets are also good for weight loss.
