Your satisfaction from food isn't simply proportional to the weight or calorie content of the food. Foods aren't created equally in terms of how satisfying they are per calorie. My point is that the conventional wisdom of eating lots of bread/pasta is counter-productive simply because they're not very satisfying. A cheesy omelet isn't more or less food than a plain bagel, but for a similar calorie count I'm a lot happier 2 hours later. That's the essence of my point.

I live in New York and so pretty much only eat in restaurants (nobody here cooks). On a keto diet it's no big deal. Restaurants make money by selling you tons of carbs to inflate entree sizes. If you don't eat carbs, there actually aren't all that many ways to blow your calorie budget. If I'm at a restaurant, I can easily order a big steak and steamed veggies and mushrooms, or fish/chicken with a fatty sauce and keep within ~600-700 calories. The restaurant has no financial incentive to give me a lot of these expensive ingredients, so they don't. Psychologically, it's a lot easier to feel satisfied cleaning your plate of those things than leaving half your huge plate of pasta uneaten.
I am saying people need to eat less calories.
They are not the same thing.
Also, anyone trying to lose weight does not need to be eating in restaurants. Obviously this is very difficult for many people, due to convenience, etc. but I suggest that if people can cut down their restaurant visits by 1 a week, they will likely lose weight.
People here seem to think I was saying the process of losing weight is easy, which I did not say. The method is simple to understand, but the execution is often the most difficult thing many people will do in their lives.
