You may find yourself sleeping a lot more now that you are at the minimum guideline intake. You may find your hair is falling out in clumps. You may find you are struggling with quite a bit of gastrointestinal distress (gas, bloating, mild abdominal pain, acid reflux, constipation or diarrhea). You may develop acne or rashes. You may find you are dealing with night sweats, or hot flashes.
All these symptoms are occurring now because the body is working hard on repairing a lot of major physical and systems damage. Respond to your need to sleep more (but never in place of eating enough food). The hair is simply regenerating. The gastrointestinal issues subside as your body gets up to speed at producing adequate digestive enzymes and the bacterial colonies return to normal. The acne, rashes, night sweats an hot flashes are all the reproductive hormones getting back up to speed.
If you have any concerns about particular symptoms that are bothersome or don't seem to be improving over time, then see your doctor.
