I’ve tested that on pets (dogs and horses). You can easily control the food intake of your pets. The pets will steal food from each other if you let them. Sure, certain pets will have propensities to get heavier more easily, but by controlling food intake, you can always achieve the desired result.
These days, kids open the fridge all the time and have money to buy food outside the home. Even parents can’t control their kids’ food intake.[/quote]
I prepare all of our meals and we eat all of our meals together. There is no question, whatsoever, in my mind that people store/use calories differently. You just have to see it yourself to understand. The difference exists even with my DH and I — he eats about the same quantity as I do, and I tend to eat more sweets and starches. While I’m about 10 lbs. overweight, he’s much bigger than I am. We use calories differently, that’s a fact.
