Healthier Scammers

While on Facebook today, I saw an ad for a website called Healthier Post claiming to promote health and weight loss. I told you the other day that I could find something to make me face-palm every day of the week! They're out to sell you a supplement of course, and I am sure that there are probably hundreds of others just like them, but I'm picking on them because I saw their ad.

I perused their website, and honestly I wouldn't have bothered writing about them, except for the fact that they are touting patently false information, and some of it would be almost comical, if it weren't for the fact that this information will make you sick and could kill you. Now, some of the information on their site was reasonable. They advocate avoiding sugar and processed flour. I think we all agree those things are not good for you. But how about this?

This is a screen capture from a page on their website, text hi-light is mine

The idea that your body cannot process fats and oils is one of the most absurd things I've ever read. And I was an Art History major for a while, trust me when I say that I've read a lot of absurd things. I'm not going to get into the biochemistry behind fatty acid metabolism, mostly because I barely understand it myself. (If you want to learn more about biochemistry as it relates to health and weight loss I suggest checking out Hyperlipid's blog, as he knows more about this stuff in his pinky finger, than I do in my whole brain.) What I will say is this, it's very basic science to understand that your body doesn't know fat you eat from fat you store. It's all fuel to your body. If what they said were true, and your body could not "process" fats and oils, humans would not have made it out of the paleolithic. If there is nothing to eat, what do you think your body runs on? It runs on fat released from your adipose (fat) tissue and ketone bodies manufactured by your liver. Your brain can use ketone bodies for fuel instead of glucose once ketone levels are sufficiently high. Research has shown that brain cancer patients could benefit from zero carb diets because brain cancer likes glucose but cannot use ketones. Go figure.

But it gets better! On another page they tell you to avoid the following foods in order to lose weight. It sounds almost like the standard government advice, but the text below has more ridiculous assertions that have no basis in biochemistry.


Another screen shot from their website, emphasis mine

Three things here, first of all your body doesn't view "natural" sugar (whatever they mean by that) any differently than any other sugar. Sugar is sugar. Glucose and fructose are all handled in exactly the same way by your body and it doesn't matter what the source is. Next they say that fats and oils are toxic. Apparently they've never heard of essential fatty acids. You know, those things that are required for you to continue living. I don't know about you but I like living, and I like to eat fat too. Now lastly, they say that you should cut these foods completely out of your diet. You know, you'd almost think they were advocating veganism, but they're not. A few paragraphs down they say, "...you should eat proteins like steak, fish, chicken, and eggs to keep you strong and give you the energy to exercise." Are they just stupid? I'm not entirely sure, but a great portion of steak, fish and all of egg yolks are fat. Maybe they're just uneducated, out to sell you a product, and have copy and pasted various (and thus contradictory) text from around the web.

The moral of this story is, if a website promotes "fast" weight loss, advocates colon "cleansing," wants to sell you something to lose weight, and does not understand that just because something is "natural" doesn't make it good or safe, do like Monty Python and RUN AWAY!

Exercise away the plateau?

I have to admit it, I'm lazy as hell. I've never been all that keen on exercising, or when I was a kid, playing. Back then, I liked to stay inside and read instead.

One summer when I was in college, I did a summer program where I was a camp counselor glorified baby sitter for high school students. We were expected to stay in the dorm pretty much around the clock with the kids. The gym however, was an acceptable place to be if we weren't in the dorm. So I started going to the gym to get the hell away from the dorm and the kids. I exercised everyday almost for about two or three hours. I had never been to the gym so much in my life. Why did I do this? I'm sure you've heard of the 'freshman 15' where the new college student gains fifteen pounds from eating the crap that Sodexo (used to be called Sodexho), or some similar food service, serves. I had gained something like 90 pounds in the two years that I had been at school. I never thought I particularly stuffed my face. I simply ate until I wasn't hungry. Skinny people do that all the time and don't gain weight. Anyway, I was approaching 250 pounds, and this after I had been down to 163 pounds (after eating Atkins no less!), from a high of 270 pounds when I was in high school. Let's just say, I wasn't having any of it.

This is before I understood how low carb works, so in addition to going to the gym I cut back my food intake. I was hungry all summer, but I lost twenty-five pounds (which left me at about 225 pounds) and in the end found it easier to do the elliptical machine for nearly an hour. I also lifted weights too. The last time I went to the gym, which was just before school started for the fall, this skinny bitch approached me and told me that I ought not to lift weights until I had lost more weight. Really? People seem quite capable of poking into your personal business. I shut her up by telling her my doctor had told me to. Well, I didn't have a doctor, but most doctors would tell you that resistance training is beneficial, especially if you're overweight.

I stopped going to the gym because during my senior year, I barely had time to sleep, much less exercise. I did maintain my weight though, and I credit that to living in an apartment-style dorm and not eating at the cafeteria very often. I think Sodexo makes it a point to inject sugar, er, I mean High Fructose Corn Syrup, into all of their food. Typical fare was a burger with fries, or mystery meat with potatoes and some other vegetable. Don't get me wrong, if I had understood how low carb worked, I could have probably eaten there on it. I just didn't know at the time. Ignorance is not bliss.

When I graduated I stayed about 225 pounds for a while. Then I decided that I really wanted to lose some weight since I was going to Europe, so I started restricting calories and going to the gym again. I typically walked on the treadmill for an hour with it set to being inclined. I did lose another twenty pounds. After my trip, all the weight came right back the second I started eating until I was content. That's a great thing about low-carb. You can eat until you're not hungry, and you don't gain weight. The same could never be said when I wasn't doing low-carb.

Anyway, I was back at 220 pounds when I started this low carb journey back in May of last year. I'm currently at about 180 lbs, which I haven't weighed since before I went to college.

So what's the point of my story? About exercise. When I used to walk a lot, especially before my trip to Europe in 2009, I would be so sore. All the time. My legs used to feel like they were on fire the next day, especially if I skived off of walking for a few weeks and then started doing it again. (Maybe the pain is what made me not ever have the inclination to be a gym rat.) The first day after walking a few miles was always hell. And it often didn't get much better. I would think, 'I have been walking five miles every other day, shouldn't it get easier?'

Well, I've been stuck at 180 pounds for about a month now, and it's kinda annoying. I am 5'9" tall, and I think I probably ought to weigh 160 or maybe a little less. My BMI is currently 26.6, which is slightly overweight. I might ought to weigh 150, I'm not sure. I'd have to see when I get to 160. Anyway, I decided that I could do one of three things to break this plateau. I could try exercising, which I haven't done, because as I said at the beginning of this, I'm lazy as hell, not to mention I'm not masochistic. I don't like pain. The second thing I could do is cut out the diet coke and splenda sweetened kool-aid I drink, since artificial sweeteners could be a problem because they do raise insulin levels (I hate plain water, and I have cut back on the diet coke, you don't even want to know how much I used to drink). Or I could cut out the bit of dairy I eat (mostly cream or half and half) since I have read of other people who said dairy caused them to plateau. I decided I wanted to try exercising first. Walking is probably good for us, and I want to go backpacking in Europe again someday, so if I keep up being able to walk long distances, that would be a good thing.

I walked two miles yesterday. This after not walking, much less exercising, in months. I'm not sore today. I suspect it's the low carb diet, which reduces inflammation. (Inflammation causes pain, particularly in the joints). It's pretty amazing actually. I'm hoping this breaks the plateau. I'll let you know.

We reap what we sow...

And in this case, a lot of wheat and corn are sown, even by our frozen northern neighbors. Canadians are not immune to the bad dietary advice given here in the States. Indeed, it seems that the poor advice has spread pretty much the world over.

A few days ago, the Leader-Post, a Saskatchewan newspaper, published an online article about how "fresh artisan bread... and warm oatmeal raisin cookie[s]" can be part of a weight loss diet. I feel myself gaining weight just thinking about that. They deride the low carb diet, saying:
"Just eight years ago, the lowcarb wave rolled through North America. Admitting to eating bread or even starchy vegetables was like confessing to a crime. Carbs were cut out and weight was lost -initially. When the dust settled, weight was gained back. Low-carb stores closed for good."

First of all, I've never heard of anyone having a problem admitting to eating carbohydrates. It's more like the opposite, where you tell people you don't eat carbs and they look at you like you've got three heads. Secondly, low carb stores? Hmm, never had any of those here. Saskatchewan must be a strange place to live. Maybe the cold has something to do with it, but I digress.

Weight is gained back after going off a low-carb diet, because low carb isn't a temporary diet. You gained weight from eating carbohydrates in the first place, so of course when you go back to eating them, you gain the weight back. That's why Atkins has a maintenance phase, and the carbohydrate intake subsequently is based on how many carbs you can eat and still keep the weight off.

The article goes on to say:
"All vegetables, fruit and grain products are carbohydrates. Since a key weight-loss strategy is to make half the plate vegetables in most meals, eliminating carbs is illogical...

Unfortunately, the wrong carbs are everywhere. Forget to bring food for a busy day and it can mean game over. Many muffins, cookies and even sandwiches available on the go lack fibre. And if vegetables and fruit weren't packed, you might be without them until returning home. If you stumble upon them, will you pay a toonie for a banana at the coffee shop?"

I'd like to know what "key weight-loss strategy" they're thinking of. I suppose they think that if we all just nibble on iceberg lettuce, that surely we'll somehow magically get thin. They go on to give bad advice, first by saying that there's nothing decent to eat on-the-go (by decent, they mean full of fiber), and then saying if you do find it, it will be expensive. I hardly qualify a banana as being "healthy." Most people's insulin levels would spike, and they'd be hungry again in an hour. As for on-the-go food, I was thinking what a great thing the low carb diet is, as you can always get a huge bacon and cheese burger with lettuce, tomato, and mayonnaise and then toss the bun. You have a good bit of fat and protein that will keep you satiated for hours.

So why am I writing about this nonsense article, when there are so many other nonsense articles out there? Because two days later the same paper published two articles about how so many people in Saskatchewan are diabetic.
"Saskatchewan has the highest combined prevalence of diabetes and prediabetes on the Prairies and a quarter of our population will be living with either condition by the end of this decade...

It might be a tiresome old message to some ears, but diet and exercise is a good prescription to follow -both for those who have diabetes and those who want to avoid it."
Well, no wonder so many people have diabetes when the advice they're given is rubbish. As the proverb goes, you reap what you sow. In this case, bad advice has sown an epidemic of diabetes and obesity. And what happens? The diabetic gets blamed for their medical condition, a condition brought on by bad advice, which leads to other diseases that eventually cause death in a very long, drawn out, painful way. We can't possibly lay the blame where it belongs, which is at the feet of people who are supposed to be educated in medicine and diet, people who should know better, and yet ignore the evidence that what they're telling people, is making people sick and killing them.

Exercising your way to health or death?

Forty years ago, your parents or grandparents would have told you that exercise was bad for you. It wears out your joints and puts unnecessary strain on your body. Currently the CDC suggests 300 minutes of moderate intensity aerobic activity each week plus weight training for "greater health benefits." That's three hundred minutes of you wearing your body out every week. And if you do more than that, they say "you'll gain even more health benefits."

Now, do you think they have specific data on this? Of course not. But they'll tell you it's a good idea anyway, and in fact tout it as a way to prevent heart disease. Wait for it though, because I found this, written for heart month, from the newspaper the Asheville Citizen-Times and I found it amusing in it's glorious contradiction:
"A key contributor to heart disease is lack of exercise — again, a factor that seems to affect busy women as they juggle jobs, kids, homes and community work and fail to make time for their own good health, Palmer said. And obesity is a critical factor, because “the more you weigh, the harder your heart has to work to give your body nutrients,” she said." [emphasis mine]

So, their first premise is that if you work your heart harder (by exercise) that you'll be healthier, but if your heart has to work harder because you're overweight or obese, that's bad. Can we say cognitive dissonance? Of course, being obese is associated with heart disease, but the primary reason for CHD isn't because your heart has to work harder, it's probably inflammation. However, I doubt having your heart work harder, either via strenuous exercise or by being obese, is very good for it.

I'm not saying that some activity isn't good, especially walking, but these people are advocating that an already busy person, who is not sitting at home watching television all day, should try to fit exercising into their already busy schedule. And that just creates more stress because they think it's a character flaw that they've gained weight and blame it on not getting to the gym. I think that makes about as much sense as telling a diabetic they should eat more fruit. Oh, wait. They do that too.

I tried to find some studies to either backup what they're saying or refute it, but it doesn't seem like any have really been done, at least with exercise alone. I would imagine to find out if exercise were beneficial, that you would take two very large groups of healthy men and women and have one group exercise and the other not. Then you'd find out if one group lived longer than the other. Most of the studies I've seen however, are in patients who already have CHD, are part of Statin drug trials, or part of a diet trial. There is no controlling for variables, they test multiple things at once, and that is not science. It's quackery is what it is.

There are multiple possibilities for why exercise could be beneficial, or not. One might be if carbohydrates cause heart disease by creating inflammation, and if you consume carbohydrates and exercise, you may burn off the carbohydrates before they can have an effect on your tissues, if you're a person who can burn them off. Most people who are obese have a problem metabolizing carbohydrates, so this probably wouldn't work for them. Or maybe if you never eat carbohydrates, you would have no need to exercise very much, and you would still live just as long as someone who ate carbohydrates and exercised. These are things that could be tested.

We should know so much more by now about what it is that is killing us, but we don't, and we won't. The food industry benefits from people eating their processed, expensive junk food and the pharmaceutical companies reap the benefits of people winding up on maintenance medication from such diets. To a lesser extent the fitness industry benefits from this too, as people try in vain to exercise to lose the weight they gain (exercise makes you hungry) by eating the "recommended diet". And the newspapers? They benefit by advertising dollars from the previous three industries to push what they want to be said.
