Laser surgery for myopia early in life may create reading problems after 40

Shortsightedness, or myopia, seems to be endemic in urban populations. The National Institutes of Health suggests that myopia cannot be prevented, and that neither reading nor watching television causes myopia. I find that doubtful, as reading is a rather unnatural activity, and there is evidence that myopia is significantly associated with amount of reading at early ages.(Source: WebMD.com)Trying to avoid reading early in life would not be a highly recommended Paleolithic-mimicking choice, except for those who later decide to live among hunter-gatherers. (In spite of our romantic views of hunter-gatherer life, it is very rare to see an urbanite...

Dietary protein does not become body fat if you are on a low carbohydrate diet

By definition LC is about dietary carbohydrate restriction. If you are reducing carbohydrates, your proportional intake of protein or fat, or both, will go up. While I don’t think there is anything wrong with a high fat diet, it seems to me that the true advantage of LC may be in how protein is allocated, which seems to contribute to a better body composition.LC with more animal protein and less fat makes particularly good sense to me. Eating a variety of unprocessed animal foods, as opposed to only muscle meat from grain-fed cattle, will get you that. In simple terms, LC with more protein, achieved in a natural way with unprocessed foods, means more of the following in one's diet: lean meats, seafood and vegetables. Possibly with lean meats and seafood making up more than half of one’s protein...

Fasting for 24 hours and ending up with a bigger waist!? This may be a sign that you are losing abdominal fat

This is such a common phenomenon that you’d expect to see it discussed more often – people fasting for a non-negligible number of hours and ending up with a bigger waist. However, it is very difficult to find anything published on it. (Lyle McDonald discussed a related phenomenon on this post on whooshes and squishy fat.) I am not talking about only a perceived bigger waist; I am talking about measurably bigger. This frequently happens with folks who were obese, lost a lot of body fat, and are trying to get rid of the stubborn lower abdominal fat.(Source [ironically]: Gograins.com.au)Fasting and ending up with a bigger waist; how is that possible?Contrary...

Liver and meatballs separated by a wall of sweet potatoes

A commenter wrote here some time ago that she liked to eat rice because rice can be easily used to separate food items on a plate. One can just as easily use sweet potatoes to do that; preparing the sweet potatoes in much less time than the rice. This post explains how, with a simple recipe.- Cut up half of a sweet potato as shown on the first photo below, adding coconut oil or butter to prevent the pieces from sticking to a microwave-safe saucepan.- Microwave the sweet potato pieces in high heat for about 5 minutes.- Use the sweet potatoes to separate food items as in the second photo below, showing beef liver and meatballs with their respective...
