I was just using parasites as an example. Normally you wouldnt think that someone with a parasite could be overweight, but I have learned differently. I'm not blaming everything on them, but it could be a possibility.
I also not ruling out overeating or not exersizing enough. Just in this case if she walks if she is walking several miles a day and lifting heavy equipment etc. That's kick butt hard work! I understand how easy it is to overeat and she has admitted that she still needs to improve but she has already been trying.
Also, some medical conditions cause people to overeat..right?
