I'm currently reading "The Low-Carb Fraud", by Dr. T. Colin Campbell, who was one of the original authors of the China Study. http://www.amazon.com/The-Low-Carb-Fraud-Colin-Campbell/dp/1... Campbell has multiple degrees in biochemistry and nutrition, and from what I can tell, seems to be pretty well respected in his field. On the other hand, Gary Taube, who wrote Good Calories, Bad Calories, and who people here seem…

Despite not being done the book yet, could you give us an idea what the general premise is, and how it somehow disproves what to me at least is the overwhelming real world effectiveness of a low carb diet for losing weight?

Oh c'mon, lighten up. Sure, kids shouldn't be eating frosted flakes and garbage like that on a regular basis, but you're not going to give your kid a birthday cake? No occasional ice cream cones? Must be fun to be your kid. Everything in moderation.

Birthday cakes, Halloween candy, Christmas candy....this is a tremendous amount of sugar, and is kind of shocking to one who grew up without it. The ubiquity of sugar today discourages moderation by normalizing consumption. It would be like having ash trays in every public space and cigarette ads on tv, with "enjoy responsibly" as the tag line.

> It would be like having ash trays in every public space and cigarette ads on tv, with "enjoy responsibly" as the tag line

Like they do with alcohol?

Seriously, what's wrong with enjoying sugar responsibly?

No, the reason sugar gets a bad rep is because of what it does to your body. The insulin response to sugar is the primary way your body stores fat and sugar itself is readily converted to fat. The glucose & fructose spikes are also source of inflammation. It is believed that this inflammation is the cause of some of the damage related to heart disease, etc.

Heart disease etc, including[1]: "This is why hemoglobin A1C is frequently used in studies that try to correlate blood sugar control to various disease processes like Alzheimer’s, mild cognitive impairment, and coronary artery disease. It’s well documented that glycated hemoglobin is a powerful risk factor for diabetes, but it’s also been correlated with risk for stroke, coronary heart disease, and death from other i…

Blood sugar levels are not a reliable proxy for dietary sugar intake.

That is demonstrably false both in the laboratory but more importantly in massive amounts of anecdotal experience by regular folks. Go read some fitness and diet forums, you think all those people who tried various different diets are imagining they're losing 20, 40, 100+ pounds on low carb diets?

>The insulin response to sugar is the primary way your body stores fat and sugar itself is readily converted to fat This is a common myth, but it's wrong. Dietary fat is what is primarily stored and leads to weight gain during caloric excess; dietary carbs just decrease the amount of fat being used for energy, but can also get stored as fat tissue during overfeeding in a process called de novo lipogenesis (which is w…

it all comes back to calories in vs calories out. 12 cans of Coke a day = healthy diet?

I'm getting sick of this ignorant sugar alarmism. Sugar is not the culprit behind all the diseases listed in the article. Obesity is [5] [6]. Unless of course you're talking about cavities.

Stay at a healthy weight by controlling caloric consumption [2]. The ar…

Doughnuts, one of my favorite foods, can be part of a healthy diet Can they?

If you start from the assumption that sugar is a poison, then you'd probably say no. That seems like begging the question to me, though.

If you examine the diets of healthy people, you'll see that some of them eat donuts occasionally. That would seem to indicate yes.

> Again, it all comes back to calories in vs calories out. Which is both true and irrelevant, because the system that governs calories in and calories out is a complex control loop. When it's working correctly, weight is effortlessly maintained within a narrow range thanks to compensating adjustments in appetite and, to a lesser extent, metabolism.

What evidence leads you to believe this? There's no prima facie reason to believe evolution has adapted mammals to a glut of f…

a bear is a perfect example of an mammal that uses its insulin response during glut times to store fat.

1. gain weight during the summer by eating high sugar, high starch, high calorie foods such as fruit, berries, roots, honey/insects, and as much whole fatty fish as it can get its hands on for a super high calorie kick. it HAS to gain weight in the summer, and does so easily on that diet.

2. during the winter it hibernates and burns nothing but fat, losing the weight and avoiding starving. people can do this too, believe it or not. fasted ketosis is a thing you can sustain for quite a while as long as you drink water.

this doens't prove anything in humans, but is an obvious counter-example to no evidence to believe that mammals don't have food glut adaptations.

but just for anecdotes' sake, what does an obese human typically eat? exactly the same diet. high sugar (soda/fruit juice), high starch (all junk food), roots (LOTS of potatoes, mostly fried), and extremely high calorie kickers like cheeseburgers and pizza to ensure a calorie surplus.

>>Doughnuts, one of my favorite foods, can be part of a healthy diet just like anything else. When you say "doughnut" you mean this[1], right? If so that's 100%, Grade A nonsense and abruptly ends any consideration I was giving your comment. 1. http://twincitiesdonut.com/images/donut.jpg

Have you ever eaten a dessert? How is that any worse than eating a donut?

Not to mention the virtually universal control of Diabetes Type II without medicines by those who adopt this type of diet. Seriously, people go from insulin dependency to normal blood sugar levels in weeks.
