Calcium - The
Key To Quick Weight Loss
Are you dieting your way to bone loss?
Are you aware that the diet you follow may be depleting your
bones of essential nutrients and increasing your chances of
developing osteoporosis? Popular diets may promise quick weight
loss, but calcium and other important nutrients are often
missing from the menu, which can lead to bone loss.
And women who consistently limit what they eat to avoid
gaining weight may undermine the health of their bones,
according to a study by ARS researchers in California. (1)
The study looked at the eating behavior of women between the
ages of 18 and 50 and found that those classified as
"restrained eaters" had significantly lower bone mineral
density and bone mineral content (key indicators of overall
bone strength and health) than women who said they weren't
concerned about what they ate.
"Exercise and eating a well-balanced diet with adequate
calcium, are two of the best ways to keep your bones strong and
healthy." advise the researchers.
Calcium is not only good for your bones but can help you
maintain a healthy, low fat diet too. There has been increasing
media coverage about numerous studies showing that a diet rich
in calcium helps reduce body fat.
Why is calcium important in weight
loss?
Calcium is a fat burner. High-calcium diets seem to favor
burning rather than storing fat. Researchers say this is
because calcium stored in fat cells plays an important role in
fat storage and breakdown.
Calcium changes the efficiency of weight loss . In fact,
study after study has shown that the people with the highest
calcium intake overall weighed the least, and the people with
the lowest calcium intake had the highest percentage of body
fat. (2,3,4)
When overall calorie consumption is accounted for, calcium
not only helps keep weight in check, but can be associated
specifically with decreases in body fat. A low daily calcium
intake is associated with greater tendency to gain weight,
particularly in women. (5)
Researchers found that adolescent girls who consumed more
calcium weighed less and had less body fat than girls who
consumed the same amount of calories from other sources.
(6)
Previous studies have shown that a higher calcium intake can
block body fat production in adults and preschool children (7),
but this was one of the first studies to show that it might
have the same effect in body-conscious preteen and teenage
girls.
But aren't dairy products fattening?
Some dieters consider dairy products to be fattening, but
the evidence suggests the opposite is true.
Consumption of calcium-rich dairy foods can actually help to
reduce and prevent obesity. Over 20 recent studies show that
milk products actually contribute to weight loss.
A new study in obese adults, presented at the First Annual
Nutrition Week Conference, showed that increasing calcium
intake by the equivalent of two dairy servings per day could
reduce the risk of obesity by as much as 70 percent. (8)
The study provided clinching evidence that calcium in
low-fat dairy products can help adjust your body's fat-burning
machinery and help keep your weight under control.
In another study, obese subjects placed on a high-calcium
diet, with yogurt as the calcium source, showed markedly
greater fat loss than those on a low-calcium diet. (9)
Numerous studies have shown that dairy calcium is more
effective in reducing body fat than other forms of calcium.
(10)
Why does diary calcium work so well?
Researchers believe that other nutrients found in milk
products act in synergy with calcium to reduce fat more
efficiently.
Glycomacropeptides (found in whey proteins derived from
milk) in particular, are known to create feelings of satiety
and fullness and decrease food intake. (11,12,13)
Foods that are a good source of calcium include cheese,
milk, ice cream, baked beans and other dried legumes, dried
figs, broccoli, most dark-green leafy vegetables, and soft fish
bones like those in canned salmon.
