Re: Machine Learning and Ketosis
#162This is delightfully nerdy and overly analytical, but I can't believe someone would go to the extent of creating this yet never think to look for counterarguments against their dieting regimen. Doing this would have given him the answer much sooner. Trying to figure out how the consumption of certain foods correlates with weight gain/loss is a waste of time because it's simply the caloric content, not the macronutrit…
There are also dozens of studies showing exactly the opposite (I've googled up just two): http://www.nejm.org/doi/full/10.1056/NEJMoa022207 , http://www.nejm.org/doi/full/10.1056/NEJMoa022637 . It's pretty safe to assume that currently science is not overly conclusive about this subject. From the point of biochemistry that claim doesn't make much sense either, as calories measured in the food (which is done by measur…
See, studies like these are the problem. They aren't calorie matched making them fully, completely invalid for debunking the point I'm trying to make.
The first study says "[the low carb diet] involves limiting carbohydrate intake without restricting consumption of fat and protein", which means calories aren't controlled for at all. Only carbs are counted. The second study has the same problem, read the methodology section.
Please, link me to "dozens of studies" that refute the link I provided above that: 1) have calories controlled in both groups 2) account for the non-permanent water weight in low carb diets and 3) find statistically significant differences in weight loss vs a regular calorie-restricted diet. You won't find a significant amount, if any.
Your second argument is a really common one and I have never understood it. Agreeing that calorie management is all that is needed for weightloss DOES NOT imply that calories are equal. Calories being equal is not a requirement for counting calories. I understand the concept of TEF and that there are several other factors that can impact what the "effective" calorie amount of foods are. I understand that the human body is incredibly complex and there is no formula for accurately determining an individual's calories.'
But none of these things realistically matter for counting calories as a tool of weight loss. You estimate your calorie intake using one of several googlable methods, then you adjust your intake over time to hit your desired weight loss rate. Any personal variances your body has or any dietary habits you have just get accounted for in the amount as you adjust it.

#163Totally anecdotal, but I want to second the recommendation of a longer fasting period. I switched to a strict-but-not-religious "no food between 7 pm and 11 am" system (with exceptions for weekends and social occasions). Within a few months I was down 15 pounds (~182 to around ~167) and had shed 4 inches off my waist (~34 to ~30). I'm about 5'10" and 41 years old. It's definitely helped with physical activity (mostly…
The only negative side effect (possibly unrelated) has been that I need a much cooler sleeping environment to be comfortable. Should that be warmer instead of cooler ? I find that my body temperature goes down when I'm fasting, so I need the room to be warmer to compensate.
That logic is fine normally, that's awake and working hours. But sleeping brings in melatonin hormonal effects and the sleep jerk mechanisms into play. So it might be true that his hypnic jerk mechanism triggers on body-env temperature differential and if he lives a warm/hot place.

One of the arguments OP used was that fatty foods satisfied his hunger faster. That still means the diet would be more effective, even if in theory all tha matters are calories. Another big point was that fasting, particularly during sleep, was very effective. Is there any studies on if this is true or a real effect? Or perhaps it also just has a indirect effect by reducing calories consumed, but he argued it was mor…
The satiation thing is a valid point (as others have pointed out). I just don't like the super high level view he took of it. I'd prefer something more controlled like eating calorically equal foods and then ranking them by how long they satisfied his hunger.
Fasting is a very effective tool for losing weight. By itself it doesn't really cause any magic (meaning, it doesn't increase the rate of fat loss on its own or anything like that). It's a great tool for diet adherence because your body eventually gets used to its eating hours. If you only eat in an 8 hour window each day, you're fuller during that 8 hour window and generally less hungry in the 16 hour foodless window.

The whole site is dedicating to intermittent fasting and is a good resource.

Sorry, I _did_ mean the opposite.
Sorry that was unclear. 8 oz of meat, fish, poultry, etc (before cooking), not 8 oz of protein itself. It's recommended to not eat more than 200 grams of protein per day on any diet.
> It's recommended to not eat more than 200 grams of protein per day on any diet.
Wat? Your protein intake depends strictly on your body's requirements.

Atkins is not a keto diet. Atkins starts keto, then reintroduces carbs. Weight loss is simple: calorie deficit. However, switching from carbs to fats and taking advantage of some of the metabolic processes your body has to offer makes the process easier for many people. Calorie deficit with less hunger and decent energy. It helps a lot.
>Weight loss is simple: calorie deficit Not that simple. People touting this are usually genetically endowed with great metabolism. I've tried this many times and reach a plateau pretty quickly and have to keep decreasing calories until it's not practical anymore. On the other hand, watching the glycemic index/load does the magic for me.
What do you mean by "great metabolism"?
Metabolic rate does not vary that much: http://www.ncbi.nlm.nih.gov/pubmed/15534426
And to be clear, you can't not lose weight with a calorie deficit.

That's true, but in a useless way.
You can't die of cancer if you get rid of all the cancer cells in your body -- that doesn't help us treat cancer.
The problem isn't whether caloric deficit works. The problem is why some people are unable to maintain caloric deficit.
This appears to be complex, and includes stuff like gut flora, medication, strong cognitive biases, among others.

#168I've had weight graphs like that and the trouble always is that if you plot further instead of it being a flat line at a constant weight it bounces back up again. It's maintaining that's the hard part.

If you can afford it (usually around $150 here in Singapore), it might be worthwhile going into a sports clinic to get a RMR reading. It's possible that your body has significantly dropped your metabolism after the weight loss, and is fighting to restore its previous weight - making further fat loss (particularly while retaining most of your lean body mass) really difficult. Ironically, in that scenario, it might be…
I'm sorry, this sounds like you're talking about "starvation mode". Do you have a decent source for this because everything I've seen around it is pseudoscience. You're suggesting that they, while feeling fine, have an enormous problem with one of the most fundamental processes which keeps us alive.
Your BMR drops as you lose weight, it might simply be that this hasn't been taken into account.
Or they're not tracking their calories.
