Sugar: The Bitter Truth
Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.

@TetrOk, I found it. He -does- list at least 2 severely negative effects from glucose overload: The liver becomes grossly enlarged,(thus that 10% I mentioned earlier becomes 10% of a much greater total), & the body becomes hypoglycemic. There’s no mention of fat storage one way or the next; certainly no implication that one remains lean under these circumstances. The only point he makes is that glucose -won’t- cause liver to failure no matter how large the dose, & that fructose -will-.

@lazur1 Sorry if this is a repost; he states: “How much glucose can the liver store? Any amount: Unlimited.” Stating there is no limit to glucose storage leads to a conclusion that “As long as I just avoid fructose; I can eat all the glucose I want, cuz you know my liver will just store it all” is false. I may have misunderstood the calorie in out portion, but he goes nowhere with excess protein and it’s fat storage capacity; and why, if he follows his advice, is he getting fat? Check it out.

@Tetra That is what I asked. I’m not sure he said exactly what you’re rebutting, in either post. I understood him mean that it IS “calories in-calories out”, but it’s never JUST “calories in-calories out”. Claimed ‘unlimited’ storage of glucose? I’ll have to listen to the lecture again. I don’t recall that. I’ve read that the liver can store 10% of it’s volume in glycogen & that muscles can store 1%, a lot, if one has enough muscle, but still a clear limit.

@lazur1 I think you’re asking me what time placement I’m commenting on in the video? I don’t recall offhand, but his statement regarding the number of calories versus our will power or in relation to our ability to burn it and then commenting on how we “can’t do it” implying a ‘therefore sugar makes you fat not excess calories’ is just flat wrong. I’m not saying sugar is good or even not harmful, the evidence speaks for itself; what I take issue with is the idea of glucose never becomming fat.

@TetraUbik I assume you’re rebutting a statement in the lecture. Do you it’s time-point?

Fucking ey..Thats one bloody long video.
July 30th, 2010 at 7:27 pm
Fascinating lecture!
July 30th, 2010 at 7:43 pm
Genius lecture.

The most destructive lies are dangerous half truths;
No matter what is presented, a caloric excess of glucose
WILL BE STORED AS FAT.
There is NO SUCH THING as a limitless energy storage device,
The liver cannot simply just keep storing glucose.
And NEVER listen to ANYONE who tells you:
“you can’t do it.”
That’s a bunch of BULLSHIT.

nice video

@n00bzor86 Indeed. But I’ve had headaches from eating ice cream too late at night.

@lazur1
More likley to be the ammines in lemons then fructose causing headaches..

This isn’t the entire picture folks. There are likely several causative factors for the obesity epidemic, one of which is certainly HFCS consumption, Check out Alan Aragon’s blog for another perspective..

@basspfosten Can’t please everyone..

Even homemade lemonade has: Just as much / Just as bad / Just as high % fructose (within about 5%) / Just as likely to trigger a migraine: Table sugar. No sugar separated from it’s source is natural.

Im never going to eat sugar again

Rather good presentation, but I dislike the patronizing way he keeps saying ” ‘kay?”.

57 people need to admit that they hit the wrong button!!!

57 dislikes? Lol uneducated morons…

I removed HFC from my diet about two weeks ago and the other day drank some lemonade that I later found out has a high level of HFC (Tropicana – which I would have *assumed* was “natural”). About 3am that next morning I was awakened by a terrible migraine… coincidence?

That was very eye opening. Very informative.

@lazur1 Thank you.

@NicoleStagg Anything worth knowing involves overcoming obstacles. Next to the essential difficulty of some subjects, perhaps the most often-occurring obstacle is the teacher, a problem shared by “A” students & drop-outs alike: “A”s focus on the subject, drop-outs focus on the teacher.

really, I couldn’t concentrate because every time he said “ok?” I just went at a blank thinking about how many times he’s said it. It would’ve been much more enjoyable without all of them; all the 100s of them!
