Day 5 of a planned 5 days of ‘no solid food’ fasting


…While we talk about protein requirements, really the body needs amino acids. This makes up about 16% of the weight of protein, so that if you eat 56 grams of steak, you do not get 56 grams of protein, but really require about 6 times more by weight (approximately).

Proteins are being degraded and resynthesized continuously. Old proteins get broken down, and the amino acids are reabsorbed to be built into new proteins. The amount of turnover is several times larger than the amount of amino acids eaten daily. However, some amino acids do get lost in the process, so we require a certain amount of protein intake. This is lost predominantly in the stool and the urine. Sweat, hair, nails etc make up a miniscule proportion of the lost amino acids.

Amino acids cannot be stored for long term energy. Any protein eaten in excess needs to be converted to glucose or fat for storage...

...So, how much protein should you take? The average necessary would be 0.6 g/kg/day (around 50 g/day) and LESS if you are trying to lose weight. However, I have seen recommendations that vary widely. Some suggest 120 g/day. Drs. Phinney and Volek recommend 1.5 – 2 g/kg/day. Yowzers. That’s super high. Do I worry about protein deficiency? No. When I start seeing a North American outbreak of kwashiorkor, I’ll be worried. Until then, the average intake is still 2-3 times what is physiologically necessary...
