After marriage, a woman’s responsibilities explode. A man, depending on his thoughts on marriage, may have more responsibility (my husband takes on 50% of the household tasks, more when I am pregnant).
So, a woman who had time to excersize and eat healthy pre-marriage/children, not barely has time to shower.
Also, weight is not the only thing that changes. Hair often looks worse for wearing after being covered, wrinkles and crows feet begin to appear…we age. Heaven forbid we don’t all look like pre-pubescent little girls without an ounce of fat on our bodies right?
