Low calcium:protein ratio makes you fat!

[Guest guest]

Has the below study been overlooked by CRONers? The fulltext has a

table 2 showing the results of a formula where at least 15mg of

calcium per each gram of protein is necessary to keep BMI in the

healthy range. This could be crucial information for those that eat

more than the RDA for protein. Presumably, a higher calcium to

protein ratio could result in accelerating lipogenesis. I can see no

harm in American Boobus displacing high insulinic carbohydrates with

more protein and more calcium.

I do wonder if this lipogenesis effect (and CLA) is a plausible

explanation for my surprising weight gain of 10-15lbs since the end

of November, despite no increase in my average daily calorie intake

or decrease in energy expenditure. All I did was cease eating grass

fed, raw milk cheese of which I ate at least 4oz every day for

several years. My body fat has increased about 3% but it feels like

a heck of lot more.

Five clinical studies of calcium intake, designed with a primary

skeletal end point, were reevaluated to explore associations between

calcium intake and body weight. All subjects were women, clustered in

three main age groups: 3rd, 5th, and 8th decades. Total sample size

was 780. Four of the studies were observational; two were cross-

sectional, in which body mass index was regressed against entry level

calcium intake; and two were longitudinal, in which change in weight

over time was regressed against calcium intake. One study was a

double-blind, placebo-controlled, randomized trial of calcium

supplementation, in which change in weight during the course of study

was evaluated as a function of treatment status. Significant negative

associations between calcium intake and weight were found for all

three age groups, and the odds ratio for being overweight (body mass

index, >26) was 2.25 for young women in the lower half of the calcium

intakes of their respective study groups (P: < 0.02). Relative to

placebo, the calcium-treated subjects in the controlled trial

exhibited a significant weight loss across nearly 4 yr of

observation. Estimates of the relationship indicate that a 1000-mg

calcium intake difference is associated with an 8-kg difference in

mean body weight and that calcium intake explains approximately 3% of

the variance in body weight.
