So, telling someone to eat MORE to LOSE weight is simple failure in math. Eating below your basal metabolism will result in fat loss, not muscle atrophy as you allude to. The reason that weight-lifters eat such a high-caloric diet is so that they have the energy necessary to amass such muscle and that their body will also use all of the excess Calories for bodily processes (metabolism). This person is trying to lose weight, explained above.

Ah well I got my information from people who gain weight and lose fat for a living... bodybuilders.
The reason I'm telling him to eat more is because he's eating
so few calories that his body is probably consuming muscles to feed itself (catabolism).
The math for dieting goes like this:
Lean Body Mass (LBM) multiplied by 13-15 (13 for
super-strict dieting - i.e. the most fat loss possible).
This is maintenance. Here you neither gain nor lose weight.
Subtract 500 calories (by either exercise or food intake), and there you have the start to fat loss with
minimal muscle loss.
Since he consumes 1,100 calories, using the above formula he would weigh 123 pounds of lean body mass.
123 pounds!!
In case you didn't know, improper dieting can lead to a fat:muscle loss ratio of 2:1. So fpr every 16 ounces of fat loss, you'll have 8 ounces of muscle loss.
Most
bodybuilders are able to put in 10 pounds of muscle mass in a
year. Can you imagine how long it would take the average joe to put on 10 pounds of muscle mass?
EDIT: Here's what undereating and over exercising CAN do to you.
