I'm sure some of these have been said. But fat is satiating. Carbs are not.

So fill up on fatty meat, not fries and pasta.

Salt salt salt! It's not health advice, but just season to taste, and slightly over if you are preparing meals at home, not out of a can. In fact, forget the canned food.

Meat grinder, large cuts of beef, free scrap fat from butcher. Boil large cut and fat for 1 minute to kill surface bacteria. Grind. Cook medium rare. It's a real nice and satisfying meal. Forget cooking to 165.
