Dairy Effect on Body Fat - Was : Re: Whey

[Guest guest]

Hi JW:

Those on 500 kcal per day shortfall eating dairy products lost a lot

more fat around the abdomen than those on a 500 kcal shortfall with a

calcium deficiency.

How much is your son eating? (rhetorical)

I will forward the PDF to you so you can see for yourself the rest of

the details.

Thanks Rodney, I've a little trouble with pdfs with my OE. I gotta revert to OE4 someday.

I think this is the abstract:

"OBJECTIVE: Increasing 1,25-dihydroxyvitamin D in response to low-calcium diets stimulates adipocyte Ca2+ influx and, as a consequence, stimulates lipogenesis, suppresses lipolysis, and increases lipid accumulation, whereas increasing dietary calcium inhibits these effects and markedly accelerates fat loss in mice subjected to caloric restriction. Our objective was to determine the effects of increasing dietary calcium in the face of caloric restriction in humans. RESEARCH METHODS AND PROCEDURES: We performed a randomized, placebo-controlled trial in 32 obese adults. Patients were maintained for 24 weeks on balanced deficit diets (500 kcal/d deficit) and randomized to a standard diet (400 to 500 mg of dietary calcium/d supplemented with placebo), a high-calcium diet (standard diet supplemented with 800 mg of calcium/d), or high-dairy diet (1200 to 1300 mg of dietary calcium/d supplemented with placebo). RESULTS: Patients assigned to the standard diet lost 6.4 +/- 2.5% of their body weight, which was increased by 26% (to 8.6 +/- 1.1%) on the high-calcium diet and 70% (to 10.9 +/- 1.6% of body weight) on the high-dairy diet (p < 0.01). Fat loss was similarly augmented by the high-calcium and high-dairy diets, by 38% and 64%, respectively (p < 0.01). Moreover, fat loss from the trunk region represented 19.0 +/- 7.9% of total fat loss on the low-calcium diet, and this fraction was increased to 50.1 +/- 6.4% and 66.2 +/- 3.0% on the high-calcium and high-dairy diets, respectively (p < 0.001). DISCUSSION: Increasing dietary calcium significantly augmented weight and fat loss secondary to caloric restriction and increased the percentage of fat lost from the trunk region, whereas dairy products exerted a substantially greater effect."

The 1200 to 1300 mg Ca doesn't look all that high.

OK, so when I was 50# heavier maybe the ffmilk, rice, fruit diet was a good choice. And maybe I did lose a higher % fat. So I'll try it again and see how much my 38" waist shrinks this week. My deficit is not 500 of course, more like 100 to 300 (today 1600 kcals).

Regards.
