It certainly is not "all just Calories in/out"!ewitte wrote:Its all just Calories in/out. All the other advanced stuff does is change the numbers and cause potential for storing an excess of anything you eat. For extremely obese people cutting Calories your more likely to lose fat. The fat is a strain on the body and it really wants to get get back to a normal weight. With severe Calorie cutting on a lean individual its more likely to come from muscle loss. The muscle loss in turn reduces the metabolism (Calories out) even further and can cause all sorts of health concerns and even organ failure.
Put it this way. If your hormones are out of wack and your body is only using 1000 Calories you can still get excess eating 1200 Calories. That will cause a 20lb weight gain in a year and mess up the numbers even more. Actually eating more and the "correct foods" most likely will level off or correct the hormone problems. So now your burning 1800Calories while eating 1600. At this point you lose 20lbs in a year.
The only thing that 1000 calories of protein, 1000 calories of fat and 1000 calories of carbs have in common is that all three produce the same measurement when burned in a bomb calorimeter! They each have a dramatically-different affect on the human body.
Sure, the extremely obese need to reduce calories, but since calories isn't their problem, just reducing calories alone won't help much, and not for very long. If just reducing calories were the solution, very few people would be obese, because they have ALL TRIED REDUCING CALORIES AND IT HASN'T HELPED!!! If it had worked, they would have kept on doing it.
They have all tried the cut-the-fat style of cutting calories, and see where it got them? Low-carb has worked much better, but it alone also obviously isn't the solution, either. Low-carb plus exercise is the best treatment known at the moment, but obviously isn't the cure. The cure hasn't been found. We (that's the royal "we" that includes all of mankind) don't know what causes, or how to fix obesity. The current state of the art just isn't adequate.
