What Hacker News says?
As a fellow endurance athlete who has experimented with fasting I would say don't waste your time. While I do think the response to fasting is somewhat personal, for me the impact upon long-term fitness, work/life stress (cortisol) [1] and ongoing metabolism [2] is just too severe to be ignored.

on “Testosterone is the drug of the future”I would recommend reading this article about the connection between vitamins D, A, and K, and how they inter-play with one another: https://www.precisionnutrition.com/stop-vitamin-d It was pretty eye-opening (and alarming) when I read it. In short: While Vitamin D is great for everyone, your body will begin lacking in vitamins A and K because of the effects of D (too much of a good thing, essentially). It's all abou…

on “Ask HN: Who is hiring? (November 2013)”I've found http://www.precisionnutrition.com/ to be one of the better resources online. I signed up for the certification and it's way more advance than what you see everyone else talking about. It explains the basics of how the body actually digests foods then goes into the day to day stuff.

I myself had absolutely no progress when IFing for some days, only dizziness and irritability.

on “Why Cutting Carbs Is So Tough”I recently came across an article discussing the relationship between vitamin D, K, A, magnesium, and calcium levels. I can't vouch for it's accuracy but it does provide a number of references if you want to go further down the rabbit hole. [1] http://www.precisionnutrition.com/stop-vitamin-d

on “Vitamin D deficiency in pregnancy is linked to autism traits in the child”http://www.precisionnutrition.com These guys are fantastic if you want to change your lifestyle. In the past, I've done something like this program and I lost about 70 pounds (meanwhile becoming relatively buff and, if I might say so myself, rather sexy). I like this program because it's a laid back version of most ketogenic diets mixed with a whole food mentality (read: it's sustainable for life).

on “How I Lost 20 Pounds in 20 Weeks With My iPhone (or: Data is King)”The study referenced in the beginning (with the 4 groups of women) did not sufficiently control diet. OP: <i> All the women were asked not to change their dietary habits... </i> They were asked, but did the women comply? Not likely, due to the compensation problem. Bottom line: Regulating exercise without regulating diet is not likely to produce results. I don't think this is news. It has been shown that one's metab…

on “Scientists have discovered a simple way to cook rice that cuts the calories”> The paper argues that this theory does not make nutritional sense. “The meat of wild animals is lean,” Thompson says. “It actually takes more work to metabolize lean protein than you get back.” In fact, eating lean meat without a good source of fat can lead to protein poisoning and acute malnutrition. Early Arctic explorers, who attempted to survive on rabbit meat exclusively, described the condition as “rabbit st…
