Caloric restriction may not be the "optimal" diet, but it's still "true". Anyone who's taking grade 10 physics can tell you exactly why the difference between calorie input and calorie output equals your change in weight. It simply cannot be untrue -- you body cannot disappear energy without it going "out", and it can't create energy without it coming "in".
The linked article is a good explanation of why IF works; I don't disagree. But you can't say, "The key to weight loss is not to reduce calories"... because reducing calories is literally the only way you will ever lose weight.
- ilitirit 8y ago> reducing calories is literally the only way you will ever lose weight. That is demonstrably false. If weight Z = X intake + Y energy expenditure, then you can reduce Z by keeping X the same and increasing Y. Obviously diet has much more of an impact than exercise, but it's not true to say that the only way to lose weight is to eat less.
- InitialLastName 8y ago> Anyone who's taking grade 10 physics can tell you exactly why the difference between calorie input and calorie output equals your change in weight. This is one of those places where you can be entirely correct but entirely unhelpful. The problem is that calorie output is both a) non-constant (even your base metabolic rate changes over the course of your life, much less any lifestyle changes) and b) influenced by environment and physical condition (your calorie burn will change in response to environmental pressures, including caloric restriction and changing body fat content).
- parliament32 8y agoCalorie output may be hard to measure, but that doesn't mean you can say "calories in/calories out is untrue!" like the author does. But you're right, this is a "technically correct" yet unhelpful answer.
