Well, the app isn't all bad. Just the little assumptions. It's actually helping me I think. I find it actually quite hard to stay under my 1200 calorie a day allotment (which is actually not enough to lose weight, but some built-in minimum) even putting in my daily exercise. But I have stayed below. According to the app, I should have lost a pound these last 2 weeks. But I haven't. Boo.
I did notice that I don't get enough protein. It felt like I ate a lot of meat every day. I eat meat for breakfast and meat for dinner. But if my lean body mass is 100lbs and the formulas give me a range between 80-100grams a day, I'm falling short almost every day. Time to eat more meat and see what happens. Maybe I will be less hungry.
