CLA, or conjugated linoleic acid, is a type of fatty acid doctors have been studying for immunity for several years. In this trial, 13 people with moderately active Crohn’s disease–a chronic autoimmune inflammatory gastrointestinal disorder–took 6,000 mg of CLA per day. This was an “open label” study, with everyone aware of the treatment and no placebo group. After 12 weeks, levels of several immune inflammatory molecules were much lower, and the Crohn’s disease activity index improved from “moderate” to “mild”. Participants also needed less medication and reported better overall quality of life, with most symptoms nearly receding into remission.

CLA helps manage weight

CLA, or conjugated linoleic acid, had several benefits including reducing body fat in earlier animal studies, but human studies have been inconclusive, doctors said. In this study, 63 people tending toward overweight or obesity took 1,700 mg of CLA per day, or a vegetable oil placebo, in about 7 ounces of sterilized milk. After 12 weeks, while there were no changes for placebo, the CLA group had lost body weight, improved body mass index score, had less total fat and fat under the skin, a lower percentage of body fat, and a smaller waist-to-hip size. The higher the body mass index at the start of the study, the larger the improvements in all measures.


Calcium burns fat, reduces fat absorption

When dieters take in fewer calories than they burn, calcium supplements may stimulate fat loss, but prior studies have been inconclusive, doctors said. In this review, researchers analyzed eight placebo-controlled calcium weight-loss studies, and found that dieters who got high levels of calcium increased fat metabolism by 11 percent compared to placebo. Those who consumed low levels of calcium before the study–less than 700 mg per day–saw the most fat-loss benefit. Researchers said the higher rate of fat-burning was equal to losing eight pounds per year.

In discussing their findings, doctors said that calcium supplements raised the metabolic rate as effectively as caffeine. The average amount of calcium linked with the largest weight-loss benefit was 958 mg of calcium per day. Doctors also said good calcium levels help control appetite.
