Conjugated Linoleic Acid (CLA) is a natural fatty acid found in meat and dairy products that has become a popular weight-loss supplement. While it has been shown to reduce body fat in animals, the evidence of its efficacy in humans is less promising. CLA is believed to block the body's ability to absorb and store fat, increase metabolic rate, and prevent fat regain after stopping its use. However, studies have shown conflicting results, and concerns have been raised about its long-term health effects and potential side effects.

CLA's effectiveness in burning fat in humans
CLA (Conjugated Linoleic Acid) is a natural fatty acid found in meat and dairy products. It is available as a fat-burning supplement and is believed to be effective in burning fat in animals. However, its effectiveness in burning fat in humans is less promising.
While CLA has been studied extensively in randomized controlled trials, the results have been mixed. Some studies indicate that CLA can cause significant fat loss in humans, with an average fat loss of 0.2 pounds (0.1 kg) per week for about six months. It may also improve body composition by reducing body fat and increasing muscle mass. However, the effects are modest and plateau after six months, with weight loss slowing down over time.
The fat-burning potential of CLA is much stronger in animals than in humans. For example, one study in mice found that supplementing with CLA for six weeks reduced body fat by 70% compared to a placebo. In contrast, human trials of similar therapies have had disappointing results. The small amount of fat loss that might occur with CLA in humans does not outweigh its potentially harmful long-term health effects.
Instead of relying solely on CLA supplements, it is recommended to incorporate more CLA-rich foods into your diet, such as dairy or grass-fed beef. Additionally, exercise training, particularly high-intensity workouts, has been proven to provide superior abdominal fat loss effects compared to low- and moderate-intensity exercises. Combining exercise with meal timing, such as eating immediately after resistance training, can also enhance fat loss and muscle mass gain.

CLA's side effects
Conjugated Linoleic Acid (CLA) is a natural fatty acid found in meat and dairy products. It is also available as a fat-burning supplement. While CLA has been shown to have positive effects on weight loss in animals, the evidence in humans is less promising.
Although CLA does not cause any serious side effects at doses up to 6 grams per day, there are concerns about the long-term health effects of higher doses. The side effects of CLA include:
- Upset stomach
- Nausea
- Diarrhea
- Fatigue
- Headache
- Insulin resistance
- Oxidative stress
- Increased liver fat
- Lowered HDL (good) cholesterol
- Increased inflammation
It is important to note that the CLA found in most supplements is different from the CLA found naturally in foods. Therefore, it is recommended to consult a doctor before taking any CLA supplements, especially if you are taking any medications or have any health conditions.

CLA-rich foods
CLA, or Conjugated Linoleic Acid, is a natural fatty acid found in meat and dairy products. CLA is believed to have various health benefits, including anti-heart disease effects, anti-cancer effects, and body fat reduction. While CLA has been shown to be effective for fat loss in animals, the evidence in humans is less promising.
If you are looking to incorporate more CLA-rich foods into your diet, here are some options:
- Grass-fed beef: CLA content is 3-5 times higher in beef from cows fed with grass only, compared to grain-fed cows.
- Whole milk dairy: CLA is found in the fat of milk, so whole milk, butter, and cheese will have higher levels of CLA than low-fat or non-fat dairy products.
- Lamb: Grass-fed lamb contains almost double the amount of CLA found in grain-fed lamb.
- Venison (deer meat): Pasture-raised wild game, such as venison, tends to have higher levels of CLA than meat from corn-fed animals.
- Eggs: Eggs are another source of CLA, with grass-fed eggs having higher levels. CLA is found in the egg yolk, and it is maintained even after frying.
In addition to these natural food sources, CLA-enriched food products, such as butter, have been introduced in some European countries. However, no spread applications are currently on the market.
While CLA supplements are also available, it is important to note that there may be long-term health risks associated with higher doses. As always, moderation is key, and it is recommended to consult with a healthcare professional before making any significant changes to your diet or taking any supplements.

CLA supplements
CLA (Conjugated Linoleic Acid) is a naturally occurring fatty acid that has become a popular weight-loss supplement. CLA is found in certain foods and is also available as a fat-burning supplement. CLA supplements are believed to reduce body fat and increase muscle mass.
Studies involving animals have shown that CLA supplementation has a positive impact on weight loss. A 2017 study on mice, for instance, found that CLA supplementation reduced weight. Another study in pigs showed that CLA decreased fat growth in a dose-dependent manner. Similarly, a 2007 study by the American Journal of Clinical Nutrition found that participants who consumed 3.2 grams of CLA per day showed a 90-gram loss of body fat per week and a one percent increase in body muscle mass per week.
However, the evidence for the effectiveness of CLA supplements in humans is less promising. While some studies indicate that CLA can cause significant fat loss in humans, the effects are modest. A 2019 meta-analysis, for instance, found that CLA supplementation led to a weight loss of only 0.2 pounds (0.1 kg) per week for about six months. Another review found that CLA caused about 3 pounds (1.3 kg) more weight loss than a placebo.
Furthermore, there are concerns about the safety of CLA supplements. While CLA does not cause any serious side effects at doses up to 6 grams per day, there may be potential long-term health risks from higher doses. A 2022 meta-analysis, for example, found that CLA supplementation increased triglycerides, total cholesterol, and LDL. Additionally, CLA-related weight loss is less metabolically healthy than other weight loss methods, as it leads to a loss of subcutaneous fat rather than visceral fat, which can have negative health consequences.
Overall, while CLA supplements may help with weight loss and muscle gain, the evidence for their effectiveness in humans is limited and there are potential health risks associated with their use. It is recommended that individuals consult with a healthcare professional before taking CLA supplements.

CLA's muscle-building properties
Conjugated Linoleic Acid (CLA) is often regarded as a fat-loss supplement. However, its potential to enhance muscle gains is also evident.
A study by Kreider et al. examined the effects of CLA supplementation during a resistance training program on strength gains, body composition, and markers of muscle catabolism. Seventy-six resistance-trained participants were given either CLA (5 grams per day) or a placebo for 7 weeks, while training 3 days per week. The group that received CLA showed a significant increase in lean mass and a greater reduction in fat mass compared to the placebo group. Additionally, CLA also showed a small but significant reduction in 3MH, a marker of muscle protein breakdown.
Another study by Blankson et al. and Thome et al. provided evidence that the use of CLA resulted in a significant reduction in body fat in human subjects, although there was no significant decrease in body weight. The only explanation for this discrepancy is a gain in muscle mass.
Furthermore, CLA is a bioactive lipid, and its beneficial effects on metabolism can last for weeks or even months. This could create a more anabolic environment for the body to build muscle while simultaneously losing body fat.
While the muscle-building effects of CLA are promising, it is important to note that there may be long-term health risks associated with higher doses. Additionally, there are more effective ways to lose weight and build muscle through proper diet and exercise.
