There are legitimate hereditary factors that come into play regarding weight. If I were prone to gain weight I’d be huge with the way I eat, for example.
My wife, runs 7 to 10 miles every day or two and eats a low low low fat diet, yet her doctor had to prescribe medication for cholesteral that was well over 300. That IS hereditary, fwiw.
Your wife has all my admiration! I could never do that!
