I'm in the process of recovering from an eating disorder (I was never really bad to the point of hospitalization or anything, but I did restrict and stopped my period and had a BMI of 17). I'm sure because of all of this, I lost all or most of my muscle. I'm in the process of gaining about 10 pounds and I'd love to put on some muscle again, the problem is, my parents won't let me go to a gym or weight train or anything like that. I'm not allowed to do excessive cardio either--the most a nutritionist will let me do is go for walks. If I eat excess calories and a diet high in protein, can I get any of my muscle back with just that and walking? If not, is there anything else I can do such as yoga, or anything not done in a gym? I appreciate any suggestions-thank you!!
