I agree that working with gradually modifying a person’s current diet is a good idea.

Many of my patients have broken jaws! Even when they get to the kitchen, they still can’t eat like they used too! 🙂

I do think that those substitutions will have to be made after some time, but I think that changes like these might come earlier when working someone into a different diet. making some changes to what you already enjoy and are used to is probably easier than switching it(at least sometimes)for something new.

I think choice architecture is actually probably the best starting point, but that’s a story for another day…

And yea, the total volume of food is usually an issue too(in real life). It’s amazing how some people lose weight after breaking a leg, for example. Someone I know lost several pounds after she couldn’t make regular trips to the kitchen.

I’ve yet to meet an obese individual that doesn’t eat too much food. It’s a habit that must be changed in the long term for them to achieve reasonable weight loss goals.
