There is a lot of research that shows the type of calorie you consume determines to some extent the next calorie you want to consume. You are more likely to be "sated" (i.e. not want to eat more calories), if you eat protein than you are ultra-processed carbohydrates, low calorie soda will leave your body yearning sugar, and so on.

When you couple this with the motivations of industrial food companies (some of whom are now owned by tobacco companies), and the research they do into the neuroscience effects of flavour, texture, even packaging of food, you'll start to spot that a push to "Real Food", and for that food to be less processed and more inclined towards protein, is more likely to result in overall calorie reduction.

One of the things that isn't cutting through on this program is saying "eat protein" is assumed to mean "eat meat", which some assume means you can eat burgers. Nope. Healthy protein is not red meat that has been fried - that's going to take a bit more education, I expect.
