Science states that obesity is dangerous to fertility
Search any peer reviewed article (one quick google search brought me to this http://www.ncbi.nlm.nih.gov/m/pubmed/10799397/) and it is PRETTY CLEAR that obesity is dangerous for both mother and child, increasing too many risk of complications to list. Not to mention that the child has a higher chance childhood obesity due to unhealthy eating habits and lifestyle,
Leading to further complications.
I will not cosign any women stating that obesity is healthy.
