It's a mistake to make assumptions about her maintenance intake and assume she's in an 800 calorie deficit. Agreed, but I think it was quite clear that I was speaking about a hypothetical person when I said "For the average, moderately active woman (requiring 2,000kcal per day) that would be a deficit of 800kcal" (emphasis added). If she was she'd be losing weight very very quickly. That's why I suggested re-checking their calculations.
