Conjugated linoleic acid (CLA) caused a small amount of fat loss, an average of 2.2 pounds after six months according to a new study. Body Weight
Weight change: -1.3 lbs with CLA vs +2.4 lbs with placebo
Body weight in the CLA group was only reduced 1.3 pounds compared to an average weight gain of 2.4 pounds in the placebo group.
Holiday Weight Gain
CLA prevents holiday weight gain: -0.2 lbs vs +1.3 lbs
CLA also prevented holiday weight gain. Those taking a placebo gained an average of 1.3 pounds during the holidays compared to a slight weight loss of -0.2 pounds for those taking CLA.
Dose: 3.2 grams per day
Subjects were given 3.2 grams (3200 mg) of CLA per day.
Metabolism, food intake, etc
CLA had no effect on metabolism, food intake, insulin resistance, etc
CLA had no effect on resting metabolism, physical activity or food intake, nor did it affect insulin resistance, cholesterol or triglycerides, liver function or inflammation.
Subjects: 40 overweight people, BMI 25-30, age 18-44
The study was double-blind, placebo controlled and involved forty overweight people who were 18- to 44-years-old and had a body mass index (BMI) of 25-30.
The CLA group had five men and 17 women, while the placebo group had three men and 15 women.
Other studies have found 3-5 lbs fat loss with 3.4 grams of CLA per day
The paper notes that a couple other studies found that CLA caused a decrease in body fat from roughly 3.7 pounds to 5.2 pounds after one year, with the optimal dose being about 3.4 grams (3400 mg) per day. One study found that doubling the dose to 6.8 grams per day did not cause any more weight loss than 3.4 grams.
Studies that have continued longer than this have found no further fat loss.
Other studies have found no effect on body fat
Other studies have found no effect on body fat.
