I didn't say she was suffering from malnutrition. But she probably will soon be diagnosable with it if she were to continue on such a low calorie diet. It wouldn't hurt to read some article on what malnutrition is. continuing on this path will likely lead to getting run down will lead to a range of symptoms from depression, to catching every passing virus to fatigue. So if the OP wants to continue on this path as John seems to think is a good idea, then she should go for it. But she must complain or be surprised when problems arise.
Walking is powered by fat. Thus, walking two hours a day does not mean your body is catabolizing muscle even if you're in a steep deficit. It might be but the body catabolizing muscle results in faster weight loss (not fat loss) than if the body was only burning fat. This is because a lb of muscle breaks down into far fewer calories than a lb of fat. Roughly 700 vs 3500. Since the complaint is slower than expected weight loss it does not follow that her body is catabolizing muscle.
Regarding the nutrition - it really depends on what the OP is eating. You appeared to be making the case that one reason the OP was not losing faster was that her body was not functioning correctly. I don't "hear" any evidence that is happening. Certainly I've never seen the case made that lack of micronutrients would slow weight loss.
