Default 'Cut down on meat to lose weight'

Ah, the meat-phobic BBC news website is at it again:

Quote:
http://www.bbc.co.uk/news/health-10726414

Overall, the researchers found that meat consumption was associated with weight gain in both men and women. More detailed analyses showed that the link was still significant after taking into account overall calorie intake, physical activity and other factors which may have skewed the results.

The team calculated that in people who ate the same number of calories, an extra 250g of meat a day - equal to a small steak - led to an additional weight gain of 2kg (5lbs) over five years.

It counters the theory that diets with high amounts of protein and low amounts of carbohydrate promote weight loss. Although it is not clear why meat would lead to weight gain in people eating the same number of calories, one theory is that energy-dense foods like meat alter how the body regulates appetite control.


When will the stupidity end? This isn't the first time I have notice a strong bias in the BBC health reporting, the last study (heck - 20 studies) that showed low carb doing well is no-where to be seen.

Oh well, more meat for me then..

I know I've mentioned this on this forum before, but... I was vegan for 4 years and I gained 50 pounds during that time.

Well, gee, then, we KNOW metabolism is calories in and calories out? Right. Obviously then, this is a flawed study.

Haha! that's what I was thinking, they are quick to ditch calories in/out theory when it suits them. So how are the people gaining weight without extra calories then, huh? Don't have an answer for that do they..

I just thought of an excellent study, I think wearing black clothes causes weight gain. We could examine the amount of black clothes people wear on average and link it to weight gain.

What kind of people did they test this on? Skinny people who started building muscle? Then I think it actually makes sense.

Doesn't muscle weigh more than fat?
If you are overweight and eat more protein, the fat in your body is replaced by muscle, you may stall or even gain weight, if I am not mistaken.

So it's probably even correct.
It's only a matter of how you interpret the data

Participants from 10 European countries, including the UK, were weighed and measured at the start and then asked to report their weight five years later.

They also filled in a detailed food questionnaire.
The end weights are self-reported as is the food intake. You can get large errors from this. Most people are clueless on the amounts of what they are eating.

Indeed. I don't understand why anyone would think there is any value to such data.

Um, what if it's the other way around? What if people, in the process of getting fat, for whatever reason, have an increased appetite for the protein or fat in meat?

Quote:
Comparisons of patterns of nutrient choice in 4- and l2-wk old genetically obese (ob/ob) mice and their lean littermates emphasizes the importance of age in selection studies (36). At four weeks of age, ob/ob mice selected the same proportions of the three macronutrients as lean mice. In contrast, adult ob/ob mice selected a higher proportion of energy from fat and a lower proportion from carbohydrate than did their lean counterparts.


The drive to fatten might cause a person to eat food that is most efficiently stored as fat--and as long as dietary carbohydrate is already above a certain point, that might mean fatty meat. Alternately, a person might tend towards the food that most immediately improves availability of energy to their cells.

Or, people with faster metabolisms might have greater proportional appetites for "energy" foods, and for people with slower metabolisms, a greater percentage of their appetite might be for "structural" foods, like protein.

Actually if you are Insulin Resistant meat presents some problems. While the biology may be complex the bottom line is that about 60% of the protein you eat can raise blood sugars. If you are diabetic and take enough insulin to avoid raising BGs it then gets converted into fat. Dr Bernstein talks about the need to cut protein if you are having trouble losing weight after you have already cut carbs.

If you are insulin resistant, chances are you eat too much carbs. Once you cut down on carbs, meat is no problem at all.

If you still can't lose weight after having cut out carbs, cutting down meat intake won't make that much of a difference. The problem is elsewhere. It's not only insulin that controls fat tissue. There's epinephrine, growth hormone, thyroid hormone, cortisol, testosterone, estrogen, dopamine, prolactin, etc. The list is long and any one of those hormones can still be so significantly off that weight loss remains impossible.

Dr Bernstein's sort of talking about within the context of a low carb diet, decreasing protein, though. I think his clinical experience gives him some credibility on this.

Could this meat the study participants were eating all that time happen to be of the fast food type accompanied by a big white bun, fries, coke, etc? That's where some people get a lot of their "meat." Makes you wonder what other eating habits the meat consumption level correlated with.

I was wondering the same thing too! They might be eating meat but with what?
