I watched 3 really interesting videos in the last 3 days. The first was a documentary on Hulu called Fat Head. Here’s the summary:
Have you seen the news stories about the obesity epidemic? Did you see Super Size Me? Then guess what? … You’ve been fed a load of bologna.
Comedian (and former health writer) Tom Naughton replies to the blame-McDonald’s crowd by losing weight on a fat-laden fast-food diet while demonstrating that nearly everything we’ve been told about obesity and healthy eating is wrong. Along with some delicious parody of Super Size Me, Naughton serves up plenty of no-bologna facts that will stun most viewers, such as: The obesity “epidemic” has been wildly exaggerated by the CDC. People the government classifies as “overweight” have longer lifespans than people classified as “normal weight.” Having low cholesterol is unhealthy. Lowfat diets can lead to depression and type II diabetes. Saturated fat doesn’t cause heart disease — but sugars, starches and processed vegetable oils do.
The second was a talk/lecture by Gary Taubes (author of Good Calories, Bad Calories – now I must read this book) called Big Fat Lies. He has a second book that just came out entitled Why We Get Fat and What to Do About It, which may be more appealing – it’s less scientific and includes explanations designed for lay-people.
The last video I watched was called Sugar: The Bitter Truth. It became somewhat of an internet sensation back in 2009 but I guess I missed it. It’s a 1.5 hour lecture on why fructose is a toxin. (I’m sold.) The lecturer is a doctor by the name of Robert H. Lustig.
If you have some time (each video is over an hour) I highly recommend them. The gist of all of them is that the obesity epidemic is caused, not by fat/saturated fat/meat, but by too much sugar and too many carbohydrates. My take on them:
The first link (Fat Head) “proves” that a high-fat diet is good for you. Um, duh. Tom Naughton’s high-fat diet consists of a lot of meat; I am still kind of undecided on the meat issue. Two more of his points are that 1) grains are doing a lot of damage (he does go into detail but I don’t want to right now) and 2) processed vegetable oils (corn oil, soybean oil, etc… – and not just he partially hydrogenated trans fat ones) are also killing us. Humans are not used to eating either of those things.
Now – I like meat, and I would eat it, but I am morally opposed to the way meat is produced in our country, and I can’t bring myself to eat it anymore. If meat were truly ethically raised? I’m still unsure nowadays. I’m getting off topic, but my takeaway from this one – fat is good. Eat more of it. Eat veggies too, though. It may be possible to have a semi-healthful fast food diet, but it’s probably better to just be more primal.
Mmm… bacon and eggs and butter.
Personal side notes:
- My “Bring on the Fat” post from last year (one year ago – to the day). Sadly I didn’t keep up with this as much as I’d have liked. Now that I’m a veggie I need to get my animal fat from butter, ghee, eggs (with yolk), and dairy (goat’s and sheep’s milk yogurts are my faves; regular ol’ organic whole cow’s milk for my coffee). Since I went veggie I have been eating too many carbs and not enough fats.
- The Great Fat Animal Experiment. This was from a year and 3 days ago; it was an intro to my passion for animal fat. I still do love animal fat; again, I’m just going to try to get it from non-meat sources.
- Way back in July 2009 (4 days before I got engaged… can’t believe I am married now!) was one of the first times I started trying to eat more fat. I didn’t really follow through, at least not to the extent that I should have. I have come a long way since then.
Big Fat Lies
The second link (Big Fat Lies) discusses the matter of why people are getting fat; is it simply that we eat too much and sit on our asses? Gary Taubes seems to think that it’s because we have too much insulin (I’m leaning towards agreeing with him, but I think the reason we have too much insulin is because we… eat too much). He basically says that we aren’t getting fat because we’re eating more; we’re eating more because we’re getting fat. He debunks Ancel Keys’ Lipid Hypothesis/Seven Countries Study which states that:
- Saturated fat increases cholesterol. (If A then B.)
- High cholesterol associated with heart disease. (B associated with C.)
- Saturated fat must cause heart disease! (If A then C.)
What a load of bologna! Ugh, too much to say about this horrible study, will post about this later (if I don’t remind me). I tend to agree with Taubes’ conclusions, but I think that there are a lot of people out there who do simply “eat too much” for probably mental reasons. It’s not just hormones that are making us fat. We have issues that also make us eat too much which starts the vicious cycle of greedy fat cells –> eat more –> greedier fat cells –> eat even more –> also be lazy because we’re too fat.
Sugar: The Bitter Truth
The last link, Sugar: The Bitter Truth, Robert H. Lustig discusses how fructose is metabolized in the body. It turns out that fructose is very similar to ethanol, which is a toxin. He also debunks the Seven Countries Study (though for different reasons than Taubes does). He’s not a low-carb advocate (unlike the other two); he thinks we just have to eat the right carbs, which does not include sugar at all. His diet prescriptions for his patients (mostly kids) are (this is around the 1:10 mark):
- Only beverages should be water and milk
- Eat carbs with fiber (ex: fruit is fructose but has fiber built in)
- Wait 20 minutes for second portions
- If you’re gonna stare at a screen (tv/video games) you have to do equal amounts of activity (playing outside)
His prescriptions are probably easier and more reasonable to follow than what Taubes thinks we should do (low-carb, lots of meat); they’re also probably more sustainable (we can’t all live on steak due to overpopulation). I’m still on the fence about carbs though. I love ’em, but they make me feel like shit. Maybe I’m just more sensitive than some people; my husband could probably live on just carbs and get along fine. (Though he did lose 10 pounds in the last month from being vegetarian – 10 pounds he did not need to lose and he is worried about. He’s practically as skinny as I am.)
What are your thoughts? On grains? On carbs? On sugar? On fructose? On saturated fats? On animal fats? On “healthy” fats? On a low-fat diet? On a low-carb diet? On Tom Naughton/Gary Taubes/Robert Lustig?
Or, if you wanna stop with the heavy topics…
What are you doing for Valentine’s Day?
Bobby got us reservations as a restaurant we haven’t been to yet but that I hear great things about.
