I know about the two meanings of the word diet. That's why I am so amazed at the quoted 5% success rate for a diet. That does not make any sense to me as a rational person. If you change the inputs (food), you will change the output (body), so how can a diet even fail? If you eat 1000kcal a day you will be/get thin. If you eat 10.000kcal you will get fat, unless you are cycling the tour de france, or  are Michael Phelps. So diets work and give you the body you deserve given the diets you have chosen. But what you say will be one of the many pitfalls the idiots to may waddle in: "when I reach a BMI of 25, I can stop my diet, eat again my 6 cinnamon buns for breakfast, stop the gym membership, and use that extra money for my daily mcbeetus run".
