In a study that looked at the effect of strength training in 62 frail seniors, the subjects who did only strength training for 6 months gained no muscle mass. Another group of subjects was given protein supplementation (via a protein shake); those subjects added an average of about 3 pounds of lean mass. The extra protein likely made the difference. Similar results have been found in multiple other studies, although it remains unclear whether protein supplementation helps to improve muscle "strength" as well as muscle mass. We don't store protein in the way we store fat (in fat cells) or glucose (as glycogen). If you consume more protein than you can synthesize into lean mass, you'll simply excrete the excess in your urine as urea. [2023] - Peter Attia

Most people don't wear glasses in the U.S., and we're not conditioned to finding men and women who wear glasses sexy. If you need your glasses to see, find a good optometrist who can outfit you with a great frame, thin lenses, and a high-quality anti-reflective coating. [2013] - Amy Webb

Most millionaires lose three companies before they win big. [2000] - Robert T. Kiyosaki

One small but revealing study found that subjects on an alternate-day fasting (ADF) diet did lose weight-but they also lost more lean mass (i.e. muscle) than subjects who simply ate 25% fewer calories every day. This study was limited because of its small size and short duration, but it suggests that fasting might cause some people, especially lean people, to lose too much muscle. On top of this, the ADF group had much lower activity levels during the study, which suggests that they were not feeling very good on the days they were not eating. [2023] - Peter Attia

There are two types of vitamin K2, the animal-derived MK-4 and the bacteria-derived MK-7. Good sources of K2 (MK-4 form) include organ meats, eggs from pasture-raised chickens, butter from grass-fed cows, shellfish, and emu oil. K2 (MK-7 form) can also be created by the fermentation of bacteria, so foods like Japanese natto (a fermented soybean), sauerkraut, and cheeses like Gouda and brie are also good sources. [2018] - Steven Lin
