Re: Dairy, Calcium helps fat loss

August 12, 2005

Hi folks:

Of course Warren posted here about a year ago that of the CR mice

that lived on average 40% longer, those that lived the longest of all

were the ones that, while eating the exact same diet, had maintained

the greatest fat reserves. I do not remember his source.

So I am not sure what we should conclude about the dairy

consumption/body fat issue.

One obvious possible resolution to the conundrum might be that the

longest lived ones had had lower caloric expenditure. Either for

some genetic reason, or perhaps because they had exercised less.

I've just never been able to get enough protein without dairy in a vegetarian diet.

My gut doesn't like dried beans or soy that much. We migrate to what we can tolerate, in large part.

Also, milk is a good reliable source of Ca. Reliable in the sense they can't take it out.

I recall an article assoc Ca with cancer, but that's "silly",( how about illogical?), because there are so many people that eat dairy. Cheese, ice cream, milk shakes, yogurt, cake, how can people avoid it?

So I have to wonder what's the biochem that causes weight loss?

I do know that whey added to my milk raises my "metabolism" (makes me feel warmer) - maybe that's the effect?

Regards.

There's no date on your posted study below but recent claims by the dairy industry in this vein have been dubunked. So I would take the conclusions below with a grain of salt.

I DO eat some diary. I use ff milk in my coffee and eat ff plain yogurt. I consider the yogurt an essential ON food. There have been studies posted about its' health benefits. One of the benefits is the elimination of yeast infections in women who ate about 1/2 cup a day. It also maintains beneficial intestinal flora.

OBJECTIVE: Our objective was to determine the effects of dairy

consumption on adiposity and body composition in obese African

Americans. RESEARCH METHODS AND PROCEDURES: We performed two

randomized trials in obese African-American adults. In the first

(weight maintenance), 34 subjects were maintained on a low calcium

(500 mg/d)/low dairy (<1 serving/d) or high dairy (1200 mg Ca/d diet

including 3 servings of dairy) diet with no change in energy or

macronutrient intake for 24 weeks. In the second trial (weight loss),

29 subjects were similarly randomized to the low or high dairy diets

and placed on a caloric restriction regimen (-500 kcal/d). RESULTS: In

the first trial, body weight remained stable for both groups

throughout the maintenance study. The high dairy diet resulted in

decreases in total body fat (2.16 kg, p < 0.01), trunk fat (1.03 kg, p

< 0.01), insulin (18.7 pM, p < 0.04), and blood pressure (6.8 mm Hg

systolic, p < 0.01; 4.25 mm Hg diastolic, p < 0.01) and an increase in

lean mass (1.08 kg, p < 0.04), whereas there were no significant

changes in the low dairy group. In the second trial, although both

diets produced significant weight and fat loss, weight and fat loss on

the high dairy diet were approximately 2-fold higher (p < 0.01), and

loss of lean body mass was markedly reduced (p < 0.001) compared with

the low dairy diet. DISCUSSION: Substitution of calcium-rich foods in

isocaloric diets reduced adiposity and improved metabolic profiles in

obese African Americans without energy restriction or weight loss and

augmented weight and fat loss secondary to energy restriction.

Hi Francesca:

And for males do not forget the confirmed association between milk

consumption and prostate cancer. In one study milk drinkers

sustained five times as much prostate cancer as those who generally

avoided it.

It would be interesting to know which component of milk is

responsible.
