This may be why people believe CLA can help with weight loss. While many studies have shown substantial weight loss in animals, a review study says that these results do not necessarily apply to humans.
Several studies show that CLA promotes slight weight loss when researchers compare it with placebo groups. However, these examples say that the evidence is inconsistent across the studies. There are no studies looking at the effects of CLA on bodybuilding specifically. A review of available research suggests that the benefits of taking CLA supplements alongside exercising vary.
The researchers, however, do include several studies that showed CLA supplements could reduce body fat and improve lean body mass, which is the ratio of fat to body weight. In one study, participants who took 1. The authors said that CLA might reduce fat deposition. Recent studies have questioned whether CLA-induced weight loss has the same benefits as traditional methods of weight loss, the latter being calorie restriction and exercise.
One study compared two groups of obese mice with characteristics of human metabolic syndrome. To test weight loss, the researchers gave the first group of animals CLA supplements while putting the second group on a calorie-restriction diet. The scientists studied the physical changes between the two groups. Both groups lost equal amounts of weight, though they had different physical changes:. The study concluded that calorie restriction was a healthier form of weight loss than taking CLA supplements.
Atherosclerosis , or hardening of the arteries, is when plaque builds up in the arteries. This is a risk factor for heart disease. One study on obese mice suggested that taking CLA supplements could protect against atherosclerosis.
However, researchers need to do further studies before they know the true effects of CLA on atherosclerosis in humans. Animal products from ruminants, such as cows, goats, sheep, and deer contain CLA. These products include meat, milk, and cheese. The amount of CLA in animal products depends on farming techniques. Products from grass-fed animals contain more CLA than those from grain-fed animals.
Over recent decades, numerous studies have shown that grass-based diets improve fatty acid ratios, specifically increasing CLA and omega-3 content, and also increase the healthful antioxidant content in beef.
Feeding animals plant sources of linoleic acid, such as sunflower, soybean or linseed oil, can also increase the amount of CLA in their milk fat. A popular method of consuming CLA-rich butter is bulletproof coffee , which combines coffee, oil, and butter.
The type of CLA in supplements is different from natural forms from animal products. To make supplements, manufacturers create CLA by chemically altering plant sources of linoleic acid. There are no established guidelines, but past studies show effects from at least 3 g a day. There have been several studies to date that look at what CLA does for the immune system — so far the results have been highly variable.
When looking at how to make a conclusion based on the science available, a good place to start is to look at what the majority of the studies show. Is there a general trend, and if so is it in favour of an effect or not? The studies show a big difference in dosages from as little as 0. The majority of the studies look usage of weeks with a few going beyond that. Perhaps the most common dosage would be around 3g daily. If supplementing, then this would best be taken with meals.
It can be found naturally in foods, or in the form of a man-made supplement. The most common food that you can find it in are meat and dairy. So, what does CLA do? Most people buy it for its potential weight loss properties. CLA is claimed to aid muscle growth, lower cholesterol, improve blood glucose levels and support healthy immune function. It is a dose-dependent supplement and has been used with as little as 0.
The jury is still out on the effectiveness of CLA as a supplement in humans. Perhaps as technology improves and more studies are conducted, what is seen in theory might be observed in a real life setting.
