In the interests of fairness, when the facts change, my mind changes too - and tonight, on Australia’s version of the BBC, the ABC, a fantastic science program called “Catalyst” concluded it’s two part story on 2 years of British and Danish research into the Atkin’s diet.

In short, after having watched this documentary, it would seem that the single most compelling research into the Atkin’s Diet has been two separate but complimentary year long research trials in the UK and Denmark. The British trial over 12 months compared the success rate of 4 different well known diets - of which one was the Atkins Diet.
The trial used 158 respondents with utterly detailed diet journals and the research found the following - the Atkins subjects lost no more nor less weight than the strict calorie controlled dieters. However, the Atkins subjects were allowed to eat as much as they wanted so long as it fell under the guidelines of the Atkins program. The 3 quarters of subjects who were on traditional low cal diets lost weight over 12 months for the obvious reason - they were simply eating less calories. But interestingly, after analysing the diet journals of the Atkins subjects, it was discovered that they too were eating the same amount of calories per average subject - and yet they were allowed to eat as much as they wanted if they wished. Hence, the question became thus… “What is it about the Atkins Diet which seemingly suppresses appetite?”
The British study then performed a trial over 480 meals between 12 men to ascertain if it was “unlimited fat” in the diet which was suppressing hunger. Their meals were doped with saturated fats during the cooking phase into pasta sauces and stuff like that. 50% of the trial ate the hi-fat doped meals and the other 50% ate the low-fat meals. All subjects were allowed to eat as much as they wanted. And that study found that the men who were eating the doped hi-fat meals were actually going back asking for more than the lo-fat guys. Ergo, it was deemed that unlimited fat is not the trigger which makes the Atkins Diet seemingly suppress hunger.
And the answer it would appear has been found by a concurrent Danish study by Copenhagen University which included 120 subjects over 12 months. The university opened a supermarket specifically for the trial subjects and each and every food item was bar coded based on carbohydrate, protein, and fat breakdown. 120 people were asked to eat whatever they wanted, they just had to promise that for one year that 100% of their food was purchased for free from the special supermarket. After 12 months the research was in… and a wonderful discovery has been made. About 60 subjects who were consistently losing weight were found to be choosing an unusually high protein diet. No elevated fat or carbohydrate levels, nor decreased carbohydrate levels. It would seem that the success behind the Atkins Diet is actually due NOT to the myth of ketosis, or the myth of peeing out calories via ketones, or the myth of zero carbohydrates - it would seem almost beyond doubt that Dr Atkins unknowingly stumbled upon a diet which naturally suppresses hunger - which in turn reduces the net total of calories being consumed. And the magic bullet it seems is lots of protein.
Now, I’m happy to concede I might not have paraphrased everything in the documentary correctly here, but that’s why I provided the link. Make sure to read the transcript to Part Two over the next few days. Most enlightening stuff.
In short, those of us who have been arguing all this time that the reason why Atkin’s Dieters lose weight is because of fewer calories have been vindicated. However, to be fair, what we also didn’t see coming is conclusive proof that the Atkin’s Diet has also stumbled upon a natural appetite suppressant in people who raise their amounts of protein. In future, I’ll make a point of noting this finding at every opportunity. It would seem that certain sorts of food actually DO suppress appetite, and they need to be very high protein in their nature.
However, what we don’t know is what an elevated protein diet will do to the human body over a prolonged period of time. To this end, I’d personally still prefer to let high exercise be the reason for MY weight control because I get to eat a balanced diet over all the food groups. But hey, the research is what it is. I can’t argue with it.
