That Twinkie Diet Story
By now, most of the LC community has read about this professor who lost 27 lbs eating mostly twinkies and other junk food. http://www.cnn.com/2010/HEALTH/11/08/twinkie.diet.professor/index.html
This DOES prove that a caloric deficit, consistently maintained, WILL result in weight (and fat) loss. What else did it prove? There can be no doubt, really, that when a caloric deficit is achieved and maintained, weight/fat will be lost. This doesn't "diss" low carb in any way. For most people, low carb diets make doing so easier (less hunger) with larger spontaneous caloric deficits. Don't knock that!!
What I think surprised many is the improvements in his bloodwork given the likelihood of a poor O6/O3 ratio, transfats, refined carbs, etc. Which just goes to show a few things. Firstly, I know I've read somewhere that a person's LDL level is largely correlated with their weight status. For me, this has been the case in my life. He lost >10% of his initial body weight. Reasonable carb consumption, even refined crappy carbs, does not cause insulin to run amok accumulating fat. At 1800 calories/day, even though he consumed a lot of carbs, they weren't in EXCESS, hence the drop in triglycerides. Lastly, the lipid derangement seems to be the result of fat stores that are "full up" and/or someone who is in chronic positive energy balance. Reverse that, see improvements.
Beyond that, what does this tell us? Not much. But it does also demonstrate that NO food, in and of itself, can be labeled "fattening". Control portions and you can eat just about anything and stay slim (truly healthy is another story). But many of these foods are, IMO, "fattening", because eaten ad libitum we'll likely consume too much of them. Take the Doritos for example. A package from the vending machine can only do so much "harm". Opening up a big bag and noshing on them mindlessly watching football, etc., will get you in trouble. I note the prof made sure to get his protein in with a daily protein shake. This probably kept him from protein-seeking hunger that likely plagues those eating junky diets causing them to overeat.
One of the commenters on another blog snarked at a Nutrition prof needing to lose 27 lbs. There are a couple of low carb diet doctor gurus who needed to devise a six week plan to lose weight too. ;-) Sorry, couldn't h'ep myself there. Seriously, though, the world is full of experts and professionals that clearly do not have healthy lifestyles despite knowing what they probably should be doing. Does that make what they "know" wrong? I don't think so. The LC community is not without its fair share of purists in theory, but obviously not so pure in practice. I'm not condemning these people, just pointing out that what's good for the goose is good for the gander in this regard. If we're looking for advice/knowledge of what makes for a truly healthy lifestyle it sure helps for the messenger to look like they are walking the talk, but we can't always dismiss a message just because the messenger isn't able to do so.

I know I'd be starving!
the processing of food alters the chemical bodily response. it's not that cupcake snack packs make you gain weight if you count out on in a daily allotment of calories, but it is physically limiting to eat an excess of real food(no dairy).
either way, no 'mindful' person would ever live off solely processed and refined food. i would like to see his body composition if he stuck to it, as well as his head of hair, sleep pattern, eyes, and belly lol
Having said that, there are studies that show that people on high carbohydrate diets often report feeling full even in hypocaloric conditions (probably due to the physical bulk of the foods), as well as many studies that confirm the superior satiating properties of protein (probably due to bio-chemical, rather than mechanical/gastric factors).
I've observed with my clients that absolute caloric values arbitrate on what's the better approach; if for example, you're a 5 foot 1 inch sedentary female wanting to lose weight, your daily calorie allotment will be very low. If you try a high fat diet, you'll end up eating very tiny portions of food; a high carb/low fat regime will allow greater dietary bulk (volume) and would (probably) be more sustainable as a consequence.
If on the other hand, you're a 6 foot 4 inch male with a physically active job, your daily calorie allotment will be a lot higher, and you'll therefore get enough food volume even on a higher fat protocol.
Bottom line: it's horses for courses...but the smaller and less active you are (and the leaner you are), the less usable options you have to choose from.

Mal, I hope you don't think I recommend following this diet! LOL. I doubt he'll be following it much longer, but I do note he supplemented with protein, veggies and vitamins. It would be an interesting experiment for him to try to maintain the weight for, say, six months continuing to eat this way.
Harry, I also think that the hunger that women feel on conventional reducing diets is due to insufficient protein. Yet it gets associated with carbs. When I was a teenager some of my "dieting" classmates ate a fruit yogurt for lunch. In those days this was full fat (they don't even make this anymore and even the lowfat stuff is in smaller containers. If memory serves these came in at around 300 cals. Those girls were always going around hungry because that's just not going to fill you up (or provide enough protein), although admittedly the yogurt on its own is far better than some of the other junk.
Funny how Colpo and Krieger NEVER mention this........
On top of all of this FAT LOSS and weight loss are NOT the same ......
We do NOT know eneough about how fat cells are regulated,.
REAL, QUALITY, SCIENTISTS ADMIT THIS , unlike the Internet jokes Colpo and Krieger.
Razwell's study looked like it might be kinda interesting, so I went looking for it. I ended up at Brandenburg’s site:
http://josefbrandenburg.com/what-happens-when-you-go-on-a-diet-%E2%80%93-why-calories-don%E2%80%99t-count-%E2%80%93-part-ii/
I think the reference was this:
http://jama.ama-assn.org/content/295/1/39.abstract
The abstract itself does not seem to agree with Brandenburg's or Razwell's claims. It looks like there might possibly be more info in the letter to the editor and possibly the associated editorial by Dansinger, but I don’t have access.
Measuring energy intake by self-reported FFQs is grossly inaccurate. See Differences between estimated caloric requirements and self-reported caloric intake in the women's health initiative and Participant characteristics associated with errors in self-reported energy intake from the Women's Health Initiative food-frequency questionnaire.
A self-reported caloric deficit of 360kcals/day could very easily be a caloric surplus.

In it he explains some of the things that people have been questioning. For example, some people found it hard to believe that he could lose as much weight as he did if he was eating 1800 Calories a day. He explains that that is the MOST he would allow himself to eat a day during this experiment, but some days he ate far less he says.
Seems like a nice guy, and open to more experiments with different kinds of "diets" including low carb to see how he fares. He says that originally he didn't intend for this to go outside of his classroom, but then he was encouraged to make it more public.
He explains how it's potentially a bit misleading about his blood work, and goes into more detail about that. I found that part very interesting.
As usual, the media reports about things of this kind and reality often don't match, so I appreciate this interview for that reason - he has a chance to explain his rationale and results in more depth w/o the usual media mangling that goes on.
This is just another of those frustratingly empty stories that proves nothing but gets media attention because it is outrageous.
Welcome to the Asylum and thanks for your input!
