In reply to crag_hopper_Jay:
> I refer you to Prof. Mark Haub who went on the twinkie diet. His cholesterol readings improved and his level of triglycerides decreased. The main point being that he followed a calorie restricted diet.
And to quote Haub himself; Haub's "bad" cholesterol, or LDL, dropped 20 percent and his "good" cholesterol, or HDL, increased by 20 percent. He reduced the level of triglycerides, which are a form of fat, by 39 percent.
"That's where the head scratching comes," Haub said. "What does that mean? Does that mean I'm healthier? Or does it mean how we define health from a biology standpoint, that we're missing something?"
Despite his temporary success, Haub does not recommend replicating his snack-centric diet.
"I'm not geared to say this is a good thing to do," he said. "I'm stuck in the middle. I guess that's the frustrating part. I can't give a concrete answer. There's not enough information to do that."
Two-thirds of his total intake came from junk food. He also took a multivitamin pill and drank a protein shake daily. And he ate vegetables, typically a can of green beans or three to four celery stalks.
-- -----------------------
So it was hardly a Twinkie diet as it was heavily supplemented. Furthermore we don't know what other dimensions of health were affected and whether this diet was sustainable.
This brings us on to the bigger question around weight loss. Body fat is not managed on short periods. Our bodies have evolved of several thousand years to manage energy over longer terms than days or weeks. Of course we can lose weight by cutting calories in a short term, but the relationship isn't linear and eventually most dieters are compelled to cave in to increasing biological cues to eat.

> Also see John Cisna who lost 37 pounds and lowered his cholesterol by eating 2,000 calories’ worth of McDonald’s food every day for 90 days. Again noting he followed a calorie controlled diet.
MacDonalds? Plenty of quality meat is avaialble in one of those along with fruit and some veg. Depends how you pick from the menu. But again the body manages fat over longer terms and it isn't clear how sustainable this diet is or how it affected wider biomarkers.
> In both cases if they are in a caloric surplus they will get fat, irrelevant of the same number of calories.
Wrong - and here is robust evidence why; Four groups, two different isocaloric diets and two different feeding windows. Different bodyfat outcomes.
