I would have a better work/life balance. I would have a live in nanny to deal with the night wakings, early mornings and school runs, and spend my time swimming or doing yoga, followed by a green smoothie and getting ready at a slower pace. Then I would work from mid morning until about 4pm, giving me time to take the kids to their activities or for a meal out. At home we would have grilled salmon or rotisserie chicken with salad and avocado, olives, nuts, cheese board, and lots of fresh fruit. So no need for a chef.
Saturdays we would all do different activities at the health and sports club, probably youngest would be in the crèche there. Then we would go for a late brunch, and spend the afternoon snuggled up watching a movie together. Evenings I would have friends over, or go out with friends.
Sundays we would have a day out with the grandparents or other family, maybe the zoo or beach. Lots of walking, but also at least one big meal out.
My eating pattern would be to eat at 8ish just a green smoothie or similar, then brunch at about 11.30am, cooked (out!) on the weekends and a chicken salad wrap on workdays (homemade), a handful of nuts at 4ish, and a cooked meal at 7pm, usually something simple at home as above, or if out then steak or a sea food pasta.
I would have therapy every week, and spend a couple of hours a week having beauty and spa treatments so I would feel great about myself. We would have 4 holidays a year, plus twice a year I would go on a holiday on my own. Somewhere with a purpose like a Himalayan yoga retreat. I would have braces fitted and my teeth made perfect, so that might impact my food choices for a while!
I would weigh about the same, but be stronger, fitter, healthier, happier and not give it any thought. I would be more toned, and what wasn't toned I could get nipped and tucked 
I would be able to afford well fitting, comfortable clothes which I loved so wouldn't want to lose weight anyway, I am overweight but if I had beautiful clothes in my size it would probably mean I just wouldn't care. It's different trying to fit your wobbly bits into off the rail Primark than having properly clothes altered for you. If I looked like a curvy hourglass and not like mr blobby dressed in a potato sack, then why would I lose weight?
I would be rich enough to not be concerned about whether I ended up with a health problem down the road, because I could afford private healthcare and health insurance and all those wonderful things. Money would give me the peace of mind to be as fat as I am, and not change it!
