When it comes to weight loss, there are countless supplements and strategies on the market claiming to be the silver bullet. One of the most popular and highly debated weight loss aids is Conjugated Linoleic Acid (CLA). But does it really live up to the hype? In this article, we’ll delve into the science behind CLA, explore its potential benefits, and examine the research to determine whether CLA can truly help with weight loss.
The Science Behind CLA
CLA is a naturally occurring fatty acid found in meat and dairy products, particularly in grass-fed animals. It’s a derivative of linoleic acid, a polyunsaturated fatty acid. CLA has been shown to have numerous health benefits, including reducing inflammation, improving immune function, and even fighting cancer.
In the context of weight loss, CLA is believed to work by:
Blocking Fat Storage
CLA has been shown to inhibit the activity of an enzyme called lipase, which breaks down fat. By reducing lipase activity, CLA prevents fat storage in adipose tissue, making it more difficult for the body to store excess fat.
Increasing Fat Burning
CLA also increases the activity of another enzyme called carnitine palmitoyltransferase, which plays a crucial role in transporting fatty acids into the mitochondria, where they can be burned for energy. This increase in fat burning can lead to increased weight loss.
CLA and Weight Loss: The Research
Studies on CLA’s effectiveness for weight loss have yielded mixed results. Some studies have shown significant weight loss benefits, while others have found little to no effect. Let’s take a closer look at some of the most notable studies:
A 2010 Meta-Analysis
A meta-analysis published in the Journal of Nutrition found that CLA supplementation resulted in a significant reduction in body fat, with an average weight loss of 0.09 kg (0.2 lbs) per week. However, the study noted that the results were highly variable, and more research was needed to fully understand CLA’s effects.
A 2015 Randomized Controlled Trial
A randomized controlled trial published in the International Journal of Obesity found that CLA supplementation resulted in significant weight loss, with participants losing an average of 3.4 kg (7.5 lbs) over 12 weeks. However, the study had a small sample size, and the results may not be generalizable to a larger population.
CLA Dosage and Timing
If you’re considering using CLA for weight loss, it’s essential to understand the optimal dosage and timing. The recommended daily dosage of CLA varies widely, ranging from 1-7 grams. However, most studies have used a dosage of around 3-4 grams per day.
In terms of timing, it’s best to take CLA with meals that contain fat, as it can help increase fat burning and reduce fat storage. Many experts recommend taking CLA with breakfast and lunch, as these meals tend to be higher in fat.
CLA Side Effects and Interactions
While CLA is generally considered safe, it can cause some side effects, including:
- Diarrhea
- Nausea
- Fatigue
- Stomach upset
CLA may also interact with certain medications, including:
- Blood thinners
- Diabetes medications
- Medications for high cholesterol
If you’re considering using CLA, it’s essential to speak with a healthcare professional to discuss potential side effects and interactions.
CLA and Other Weight Loss Strategies
While CLA may have some benefits for weight loss, it’s essential to remember that it’s just one part of a comprehensive weight loss strategy. Combining CLA with a healthy diet and regular exercise can lead to even greater weight loss results.
Diet
A healthy diet that focuses on whole, unprocessed foods can help support weight loss. Aim to include plenty of fruits, vegetables, lean protein sources, and whole grains in your diet.
Exercise
Regular exercise is crucial for weight loss and overall health. Aim for at least 150 minutes of moderate-intensity exercise per week, including strength training exercises to build muscle mass.
Conclusion
While the evidence for CLA’s effectiveness for weight loss is mixed, it may still be a useful tool for those looking to shed a few pounds. By understanding the science behind CLA, choosing the right dosage and timing, and combining it with a healthy diet and regular exercise, you may be able to unlock the power of CLA and achieve your weight loss goals. Remember to always speak with a healthcare professional before starting any new supplement regimen.
Remember, weight loss is a complex process, and there is no single magic bullet. A comprehensive approach that includes a healthy diet, regular exercise, and potentially CLA supplementation may be the key to achieving sustainable, long-term weight loss results.
What is CLA and how does it work?
CLA, or conjugated linoleic acid, is a type of fatty acid that is found in meat and dairy products from grass-fed animals. It has been shown to have a number of potential health benefits, including reducing body fat and improving immune function. CLA works by inhibiting the activity of an enzyme called lipase, which breaks down fat for energy. By inhibiting lipase, CLA reduces the amount of fat that is stored in the body, leading to weight loss.
CLA has also been shown to increase the activity of an enzyme called carnitine palmitoyltransferase, which helps to burn fat for energy. This means that CLA can help to increase the amount of fat that is burned for energy, rather than being stored in the body. Additionally, CLA has anti-inflammatory properties, which can help to reduce inflammation in the body, which is a known risk factor for many chronic diseases.
How does CLA help with weight loss?
CLA has been shown to be effective in helping with weight loss in a number of ways. Firstly, it can help to reduce body fat by inhibiting the activity of lipase, as mentioned earlier. This means that less fat is stored in the body, leading to weight loss. CLA has also been shown to increase the activity of carnitine palmitoyltransferase, which helps to burn fat for energy. This means that more fat is burned for energy, rather than being stored in the body.
Additionally, CLA has been shown to suppress appetite and increase feelings of fullness, making it easier to stick to a diet and lose weight. Studies have also shown that CLA can help to improve body composition, by reducing body fat and increasing lean muscle mass. This can help to improve overall health and fitness, as well as reduce the risk of chronic diseases such as diabetes and heart disease.
What are the benefits of taking CLA supplements?
Taking CLA supplements can have a number of benefits, including weight loss, improved body composition, and improved immune function. CLA supplements can also help to reduce inflammation in the body, which is a known risk factor for many chronic diseases. Additionally, CLA supplements can help to improve blood sugar control and reduce the risk of developing type 2 diabetes.
CLA supplements are also convenient and easy to take, and can be found in a variety of forms, including capsules, tablets, and softgels. This makes it easy to incorporate CLA into your daily routine, and to experience the benefits it has to offer. Additionally, CLA supplements are generally considered to be safe and well-tolerated, making them a great option for those looking to improve their health and fitness.
How much CLA should I take to see results?
The amount of CLA that you should take to see results can vary depending on your individual needs and goals. However, studies have shown that taking a dose of 3-4 grams of CLA per day can be effective in promoting weight loss and improving body composition. It’s also important to take CLA consistently, as the benefits may not be seen immediately.
It’s also important to note that CLA is a fat-soluble nutrient, so it’s best taken with a meal that contains fat. This can help to increase the absorption of CLA and make it more effective. Additionally, it’s important to choose a high-quality CLA supplement that is made from a reputable manufacturer, as the quality of CLA supplements can vary widely.
Are there any side effects of taking CLA?
CLA is generally considered to be safe and well-tolerated, and side effects are rare.

If you are taking any medications, it’s best to talk to your doctor before starting to take CLA. Additionally, CLA may not be suitable for certain individuals, such as those with bleeding disorders or those who are taking anticoagulant medications.
Can I get enough CLA from food sources?
While it is possible to get some CLA from food sources, it can be difficult to get enough from diet alone. CLA is found in meat and dairy products from grass-fed animals, but the amount of CLA in these foods can vary widely. Additionally, many modern farming practices involve feeding animals grains rather than grass, which can reduce the amount of CLA in the meat and dairy products.
To get enough CLA from food sources, you would need to consume large amounts of grass-fed meat and dairy products on a regular basis. This can be difficult and expensive, especially for those who do not live in areas where grass-fed products are readily available. Taking a CLA supplement can be a convenient and effective way to ensure that you are getting enough of this important nutrient.
Is CLA safe for everyone?
CLA is generally considered to be safe and well-tolerated, but it may not be suitable for everyone. Pregnant or breastfeeding women, for example, should avoid taking CLA as there is limited research on its safety in these groups. Additionally, people with certain medical conditions, such as bleeding disorders or diabetes, should talk to their doctor before taking CLA.
It’s also important to note that CLA may interact with certain medications, such as blood thinners and diabetes medications. If you are taking any medications, it’s best to talk to your doctor before starting to take CLA. Additionally, CLA supplements can vary in quality, so it’s important to choose a high-quality supplement from a reputable manufacturer to minimize the risk of side effects.
