You make me happy that the US withdrew from the agreement.

Diet and nutrition / Re: urea, dementia, high protein, in the news now.
« on: December 12, 2017, 10:23:02 AM »
To expand on Jayjay's post, the urea could for example, be the result of breakdown of proteins from brain cells after they die.  In this case, the urea would be the result of the dementia, not the cause.

I think it's notable that the principal investigator's main area of study is metabolic syndrome.  Metabolic syndrome eventually leads to high blood sugar levels, overloading of the kidneys to remove the excess blood sugar, and kidney dysfunction, which would interfere with the body's removal of urea.  So even if the urea causes the dementia, it's likely ultimately because of excessive dietary carbohydrate intake, not excessive protein intake.

Welcome!  Sounds like you're off to a good start.

I'd recommend getting rid of the beans and oats when you're ready, preferably before you develop presbyopia, which happens to most people in the mid 40s.  Settling in to the lack of other starches first is fine, though.

'I also got a rash on my left wrist, which might also have been related to the excess sugar.  I spread some coconut oil on it and it disappeared within a couple of hours.'

highlighted and copied this(above) since I forget how else to do it. Very interesting I've had a rash on my left forearm for months and am having trouble isolating the cause...never thought of a sugar connection. doctors cant give me any answers either..more thoughts and info about your experience with this would be great. The flare ups are really itchy and bumpy when it happens as it is now...and yes a whole lots of sugar lately and carbs  :embarassed: >:( holiday eating weaknesses must be overcome!!!

I missed this; sorry.  The rash did not come back.

One of the things people notice on paleo is much less body odor; there's a thread around somewhere on that.  Bad body odor is known to be bacteria related, and at least some saturated fatty acids have antibacterial properties.  There's also a theory that most skin rashes are caused by bacteria, which I believe to be true.

My theory is that on strict paleo, especially ketogenic, the skin expresses a certain amount of saturated fat, which protects against the bacteria as well as most chemicals one might come into contact with in the wild.  Higher carb diets drive saturated fat into fat stores, meaning less saturated fat on the skin, and possibly more sugars or polyunsaturated fats the bacteria can use as food.

Spreading coconut oil on the skin may have a similar effect, since coconut oil is highly saturated and has high amounts of lauric acid, one of the saturated fats known to have antimicrobial qualities.

I've also started using small amounts of coconut oil on my daughter's hair once every week or two when I brush it; no stink - I guess due to the antimicrobial properties - and it makes the hair so much easier to manage.  If she were strict paleo, adding the fat from the outside might not be necessary.

I'd forgotten about the Larabars, but they stayed gone.  However, the chocolate got out of hand.  My schedule, between jobs and kids and a mismatch with my natural late schedule, has been and is difficult, and trying to manage it with the caffeine in the 86% chocolate resulted in chocolate addiction and excessive chocolate consumption.  The combination of chocolate and difficult sleep schedule caused me to gain weight, peaking at my lifetime maximum of 155 pounds, versus my healthy range of 135-145 pounds.

I've switched to 100% chocolate, which I'm hoping will help me limit consumption to those times when I really need the caffeine.  Back down to 152 pounds so far.  I'd like to get to a more regular sleep schedule, but that doesn't seem to be in the offing.

Eating high fat meat rather than lean meat can help stretch the money, since high fat meat can have twice the calories for less money.

Diet and nutrition / Re: ketosis is so slow! how long do cravings last?
« on: October 29, 2017, 12:30:25 PM »
I missed this thread the first time around.  I've been in ketosis for the better part of the last 9 years, so I may have a different perspective.

First, regarding ketostix:  I've found that the Bayer ketostix are quite accurate and useful; granted I've only used the older style on paper strips, and not the newer style on plastic strips.  The quality control on the diet oriented keto strips seems to be weaker; I once left a strip in the cabinet out of the container overnight, and it showed a trace level in the morning even though it had never touched anything but air.  As far as I know, the diet oriented strips come only on plastic backing; I still think they're fine for small and above level measurements, though I'd be skeptical of trace level measurements.

When going into ketosis, one will go through a period of about a week of "low carb flu"; there's a whole thread on that which I believe is pinned.  This is the period when your body first tries to stay on a carb metabolism by turning protein into glucose with gluconeogenesis.  That's pretty clearly what the original poster was going through.  If you give in to the carb cravings and knock yourself out of ketosis, then try again, the whole thing will start over again, so going in and out of ketosis is probably the worst thing to do.  If you stay solidly in ketosis, the carb cravings go away after a week or so - but see below on anaerobic exercise.

Ketosis is best for aerobic endurance sports - for example, distance running - because as long as you don't go into the anaerobic range, you can just burn fats.  High effort, anaerobic activities, like weightlifting or sprinting, get extra energy from glycolysis, which uses blood glucose and in turn glycogen stores.  Glycogen stores tend to be low in ketosis, so ketosis may limit anaerobic activity.  If you're careful, you can do anaerobic exercise in ketosis, but you'll need a carefully limited amount of fruit after workouts.  Resorting to nonpaleo carbs like rice or other starches, or too much fruit, will still knock you out of ketosis.

Of course you don't need to be in ketosis to use the paleo diet.  Personally I feel best when I'm in ketosis, but nonketogenic paleo is pretty close, and still way better than nonpaleo diets.

Welcome.  Stick with meat - including fish and eggs - fruit, and leafy greens and you'll do fine.  If you are trying to lose weight, don't overdo the fruit.

Research / Dietary fat causes inverse effect on cholesterol
« on: July 26, 2017, 10:37:43 AM »
Article and, especially, video showing that total and LDL cholesterol levels vary inversely with the previous three day average dietary fat intake.
