Calcium - The Key
To Quick Weight Loss
by Priya Shah
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.
