The Battle of the Diets: Is Anyone Winning (At Losing?)
January 17, 2008 presentation by Christopher Gardner for the Stanford School of Medicine Medcast lecture series. The case for low-carbohydrate diets is gaining weight. Christopher Gardner, PhD, assistant professor of medicine at the Stanford Prevention Research Center, has completed the largest and longest-ever comparison of four popular diets using real-world conditions, which he discusses – the lowest-carbohydrate Atkins diet came out on top.

So what’s the cause and what’s the effect? Is obesity caused by sedentary behavior? In our fat vs lean sprinters, obesity is the cause (does not get selected for the sprint team), sedentary behavior is the effect (gets no practice on the track).

The same is true for strength competition. The stronger gets selected for the team, the weaker doesn’t. The cause is greater strength, the effect is more practice.
Strength is primarily a function of muscle mass, which is primarily a function of hormones, namely testosterone. The more T, the greater the muscle mass. We could say that the best athletes are those with the most T.

@ABL36
If T is the primary factor for strength, what’s the primary factor for obesity? It’s a hormone: Insulin. Just like T and strength, the more insulin the more obesity. Just like T determines if we get selected for the team because of our strength, insulin determines if we get selected for the sprint team because of our leanness and obesity.

Growth hormone during child growth determines final adult height. The more GH, the taller we get. There’s a disorder called gigantism where the pituitary produces too much GH. A kid with more GH than another will grow taller, and will be selected for the basketball team. The shorter kid won’t. So, more GH, gets selected, gets more practice, becomes an athlete.
The cause is more GH, the effect is more practice.

@ABL36
In all examples, the cause is hormones, the effect is activity level.
More T = more active
More insulin = less active
More GH = more active
From there, we can determine in advance who will become a successful athlete. With study and practice, we develop, improve and maintain skill. The more practice, the better the skills. Being leaner/stronger/taller means we get selected for the team, we get more practice time, we become successful athletes.

At 20:00 Gardner says “if all groups had really cut back that many calories they would have all lost 40 lbs.” He attributes the discrepancy in weight loss to false reporting of calories consumed. However, this would require consistent false reporting in some groups but not others.
A better conclusion is that the calories burned in all 4 groups was not the same. The Atkins group had relatively more energy available while the other 3 groups had relatively less energy.

None of that matters because it doesn’t work like that. The cause of obesity is not overeating. The cause of weight loss is not undereating. Obesity is a disorder of excess fat accumulation, not a disorder of overeating. So what controls fat accumulation?

I am interested in the formula he gave to see if you have insulin sensitivity. Is is triglycerides divided by HDL with a value of equal or more than 3?

I tried a bunch of of the items mentioned here, but I need to state that nothing even compares to DietOramy unwanted weight reduction plan plan in terms of well being and bodyweight loss – search google, there is a great deal of no cost material…
January 15th, 2012 at 10:38 am
I’m not really certain if this is the suitable diet regimen regime for anybody, yet DietOramy diet regimen regime surely helps my grandma lose all that extra fat deposits. There’s sufficient free information on the Internet about that, simply use Google…

Consider hockey recruiting at a young age. The 10 year old is stronger, faster, smarter than the 9 year old. So when we select who plays, we select the 10 year old. The same is true with fat vs lean. The leaner will be faster, therefore he will be selected for the sprint team. If he’s selected, he will get more practice and eventually become an athlete. The fat kid will not be selected, will not get any practice, will not become an athlete.

“You can be an athlete and not look lean and you can be a non athlete and look lean by genetics.”
That’s correct. But the question wasn’t about athletes, but about lean vs fat. A lean sprinter will tend to be faster than a fat sprinter. Both are athletes, but the leaner of the two tends to win more competitions by virtue of being leaner, not by virtue of being an athlete.

@arrogantcoconut its not the scientists fault dude, its the freaking government. Only certain information is approved by the fucking FDA and a lot of it is old and is bull shit by now.
January 15th, 2012 at 10:38 am
@JackFook I disagree. You can be an athlete and not look lean and you can be a non athlete and look lean by genetics. It’s a lot about genetics. Any one who is not living a sedentary lifestyle is an athlete. Do you lift weights atleast 3 days a week? Yes? Then your not sedentary. Are you lean while you do this? No? Then your still an athlete reguardless.of how you look. I’ve seen fat athletes and I’ve seen skinny and muscular, even in the same sport. Athletes come in different shapes and sizes.

@sweetgirly64 First of all 25lb of what fat or muscle? Secondly what makes you think this will be appropriate for all of us. Was your initial goal to loose pounds from anything period or was it to gain muscle while loosing fat to look fit. These are the questions of a personal trainer and what annoys me the most when people tell me they want to loose fat or look fit. Fit can mean different things to anyone. You gotta be more specific about your goals or in this case, what you achieved,.

Between two sprinters, for equal strength, the lightest of the two will tend to be faster. He’s not lighter because he’s faster, he’s faster because he’s lighter. Basic physics.
Between two cars, for equal engine power, the lightest of the two will tend to be faster. It’s not lighter because it’s faster, it’s faster because it’s lighter. Basic physics.

Think about the PE class tests to see who’s good at what. There’s no consideration for how fat or lean somebody is. The only consideration is for speed, strength, endurance, agility, etc. Lean people tend to do better in all those things than fat people. Except perhaps strength, where some of the strongest men in the world are basically obese, i.e. weightlifters. Even then, some of those weightlifters are extremely lean.
We are athletes because we are lean.

“Long distance runners, swimmers, and other athletes eat lots of carbs and are thin.”
Ever see a fat sprinter? Maybe it’s because a fat sprinter has no chance to beat a lean sprinter. How many Olympic disciplines do you know where being fat is a competitive advantage? You believe that exercise makes people lean. In other words, you believe people are lean because they are athletes. But the reality is that people are athletes because they are lean.

@SizzlechestXXX Impressive come back. I’ll have to use that myself.
