Your points are very interesting over-all, but this seems fallacious:
Another way we are finding this is children of women who are obese and/or hyperglycemic (gestational diabetes or poor diabetes control) are more prone to obesity or type 2 diabetes themselves, independent of post-gestational life. And if their mothers happen to have a gastric bypass and lose significant weight, then have another pregnancy? The children conceived after the weight loss seem to be no more likely to have weight issues or diabetes than children of non-obese women.
Of course, children born to mothers having gastric bypass should be more prone to obesity (and diabetes), than non-obese mother (irrespective of (pre-) pregnancy behaviors), because their having got the bypass in the first place is indicative of their predisposition to obesity.
