The FastDay Forum

Data obtained in vitro suggest that the ability to mobilize fat
decreases with age. We determined lipolytic rates in vivo in normal weight young adult (22-33 yr) and elderly (65-77 yr) subjects. The subjects were studied after a 12-h fast and again after 60-82 h of fasting.

Interesting to see changes in ketones, insulin, glucose and fat release from storage. Although the fat release rate per adipose tissue was lower in the older subjects the rate per lean mass was similar.

The mean release of palmitate from adipose tissue into
plasma approximately doubled with the 60- or 80-h fasts. Since
palmitate is typical of other fatty acids and usually constitutes
-25% of total circulating fatty acids (31), the rate of lipolysis
at the end of the fasting period represents -4,000 kcal of potential energy released into the circulation per day. This exceeds
daily energy needs and supports previous observations that only
a portion of the FFA flux is oxidized for fuel

You post this just when I am still trying to come to terms with having a buss pass?

You could look at it as free money, though you do have to use a bus to benefit.

Sorry.

Actually, Phil I love my bus pass and my senior railcard but not that it's harder to lose weight Thanks for the link, it's interesting reading, just slightly depressing for us oldies!

Looks like a good read, thank you. And our bus passes are not free, I worked full time and paid tax for 45 years to get mine, hardly free, but hey, I know what you mean and like dhana I just love mine although we don't get the rail card thingie in England but I have no plans to return to the country of my birth just for a train pass.

Keep up the good work Phil, you are fantastic at finding all these things for us, thanks,
