CLA is found in meats such as turkey.

You can do a quick search on the internet for CLA before/after photos. There are many photos of people who seem to have lost weight and toned up after consuming conjugated Linoleic Acids, which is a type fatty acid that is primarily found in beef and dairy products.
Conjugated Linoleic Acids (also known as CLA) is a health supplement that claims to help you lose weight, lower cholesterol, and even beat cancer. These claims sound great, but there isn’t much scientific evidence to support them.
According to a September 2015 review in the Journal of the International Society of Sports Nutrition (JISSN), CLA plays a significant role in fat metabolism. However, the facts may show that these claims are a bit exaggerated.
CLA refers to a group of fatty acids produced in the digestive tracts ruminant mammals. Ruminants are animals that ruminate their plant food in a special stomach, before it undergoes complete digestion. Ruminant animals include cows as well as goats, sheep, and buffalo.
Consumed by humans as a result of eating meat and dairy, CLA can increase lipolysis (the process of converting stored energy into body fat), decrease lipogenesis (the conversion to energy to body fat), and promote apoptosis in the adipose tissues. CLA can help you lose fat and prevent your body from burning it.
CLA is a functional food. This means that it has health benefits beyond its nutritive value in calories and macronutrients. CLA has been described as having the ability to positively impact body composition, cardiovascular health and immunity, diabetes, cancer, and other conditions. CLA-80, Tonalin and Tonalin are the names used to market CLA in the United States.
According to the Memorial Sloan Kettering Cancer Center, although CLA is promoted as a weight loss product in CLA before-and-after pictures, studies have shown mixed results.
In September 2015, a review published in the Journal of the International Society of Sports Nutrition examined 16 random clinical trials. All of them involved between 14-401 subjects between 2010 and 2015. Nine of those trials found no benefit from CLA. There were no effects on platelet function, physical training, cholesterol levels, waist circumference, glucose metabolism, insulin sensitivity, or any other benefits.
These trials showed that CLA was effective in reducing inflammation markers in rheumatoid patients as well as in reducing tumor invasion, resistance to treatment and tumor invasion in patients with rectal carcinoma. CLA supplementation doesn’t make a huge difference in your overall health. It can help with symptoms of certain diseases, such as weight loss and fitness.
Combining CLA with exercise programs can often lead to changes in body composition and weight. Chemico-Biological Interactions published a March 2013 study that involved 18 sedentary male volunteers. One group took CLA while the other received placebos for 30 days. They exercised three times per week, and one group took CLA. The study found that CLA was no better than exercise alone.
Another 2013 study was published in Hospitalaria Nutrition in November. It looked at 38 volunteers who consumed 200ml of skim milk daily with 3 grams of CLA and 3 grams olive oil. This case showed that subjects experienced a loss in body weight and fat mass. However, this was combined with a healthy diet and regular exercise.
CLA is used by some athletes to increase their muscle mass and strength after heavy resistance training. In Nutrition and Metabolism, a February 2015 review found that high-doses of CLA can have both short-term and long-term benefits. They not only reduce fat mass, but also increase lean mass.
Journal of the International Society of Sports Nutrition published a review that found that very few studies had looked at CLA other than physical activity. This led to the conclusion that CLA’s benefits for improving body composition were “discordant,” insufficient, and not unanimous.
CLA is safe to consume daily according to most of the CLA reports. There are few safety concerns with CLA when consumed in daily doses of between 2.4 and 6 grams per day for up to 12 month, according to the National Institutes of Health Office of Dietary Supplements.
A February 2015 review in Nutrition & Metabolism did not include any studies that stressed a specific time of the day when subjects should take CLA. However, most of the studies were done daily.
It might be worth looking for a time when side effects will not affect those suffering from nausea. According to the Cleveland Clinic, taking dietary supplements without food can cause nausea. Supplements taken right before exercising will also increase your gastric acid production.
CLA Special Considerations
CLA, like any other dietary supplement can pose health risks to people with certain health conditions. If you are:
* You have metabolic syndrome.
* You are taking blood-thinning medications.
* You may have diabetes because CLA can cause insulin resistance and increase blood glucose levels.
* You have heart disease, or are at high risk of developing it. This could increase cell damage processes.
Although the before-and-after photos of CLA users may be genuine, it is likely that CLA isn’t the only thing they have done to improve their lives. CLA’s effects on weight loss are not significant and may be of limited relevance, even if they include it in their plans. Review of studies on human subjects have shown that CLA’s safety and efficacy are still unknown.
Experts in weight management say that people should not turn to weight loss supplements. Instead, they should adopt new lifestyle habits and make lifestyle changes to improve their long-term health.
Weight-loss products can be expensive and may interact with medication. Your doctor will be able to tell you if a weight loss supplement or medication is right for you.
Mayo Clinic recommends eating a healthy diet rich in fruits, vegetables, grains and lean protein. They also suggest at least 150 minutes of moderate exercise per week, or 75 minutes of vigorous aerobic exercise.
