Dairy Effect on Body Fat - Was : Re: Whey

[Guest guest]

Hi folks:

Well Al sent me the PDF of the study Apricot had pointed out to us.

MANY thanks to Al, and to Apricot. That is a very interesting

study. Although a fair amount of the terminology is beyond my pay

grade, with the help of a medical dictionary I think I get the

message.

There are apparently dozens of studies in animals that show that if

they are fed calcium supplements, or to an even greater extent dairy

products, they have much reduced body fat compared with a calcium

deficiency. The following direct quote purports to explain

why: " ..... the suppression of these hormones via increases in

dietary calcium facilitates repartition of dietary energy from lipid

storage to lipid oxidation and thermogenesis " . Translated into

language I can understand I think that means calcium causes more fat

to be burned resulting in a higher body temperature.

It also says it has been shown that additional calcium promotes the

death of fat cells in mice. And it notes that one mouse study showed

that the effects were much greater when non-fat dry milk was used

than when CaCO3 (chalk, as in most calcium supplements) was used as

the source of calcium. So the fat component in milk is not

necessary, apparently. But they do not disclose the milk products

they used in their own study!!! They did say that whey has been

shown to have these effects. (Yes. I can hear you asking .......

what kind of whey was it? They don't say.) They also mention that

some studies show some build up in muscle associated with the loss of

fat.

This makes me wonder if I shouldn't do a test on myself and get some

fat-free yoghurt, eat it Friday and Saturday (so that when I fall

asleep it is on the weekend) and see if there is any noticeable

effect on my body temperature.

It also raises the issue of how many calories per day must be being

burned off by the presence of the additional calcium for the loss of

weight they observed. More on that in another post.
