Lol what a load of BS. Wouldn't it be lovely to maintain on 2000 😂  Anyway, the classic diet attempt and failure isn't exactly restricted to women. Basically anyone going on a diet decides it's going to be super healthy and natural and low cal and then blows it. That's the typical failure and the reason people think dieting doesn't work.  But I can't see anyone taking advice from someone who thinks 2000 is a reasonable intake for most active women.
