Cla And Keto: A Powerful Weight Loss Combination?

Conjugated Linoleic Acid (CLA) is a popular supplement for those on the keto diet, as it is believed to help reduce body fat and increase muscle mass. CLA is a type of fat found naturally in meat and dairy products, with grass-fed animal products containing higher levels of CLA. While some studies have shown that CLA can help reduce body fat in animals, the evidence for its effectiveness in humans is less clear. Some human studies have shown modest weight loss benefits, while others have shown no change in body composition or weight when compared to a placebo. The safety of CLA supplements has also been debated, with some research suggesting it may cause inflammation or liver damage. Overall, while CLA may be a helpful supplement for some people on the keto diet, more research is needed to confirm its effectiveness and safety.

CLA's effectiveness in reducing body fat

Conjugated linoleic acid (CLA) is a naturally occurring fatty acid found in meat and dairy products. CLA supplements are often used for their purported fat-burning effects. However, the evidence for CLA's effectiveness in reducing body fat is mixed.

Research has shown that CLA is effective in reducing body fat in animals, but the results in humans are less promising. While some human studies have found a modest weight loss benefit from CLA supplementation, the amount of weight lost is relatively small and does not have a significant real-world benefit.

For example, one review of 18 high-quality human studies found that those who supplemented with 3.2 grams of CLA per day lost an average of 0.11 pounds per week compared to a placebo. Another review of long-term studies found that taking 2.4-6 grams of CLA per day for 6-12 months reduced body fat by 2.93 pounds compared to a placebo.

It is important to note that the form of CLA found in supplements is significantly different from the form found naturally in foods, and this may be why CLA supplements have been associated with negative side effects. The safety of CLA supplements has been debated, with some studies finding no adverse effects, while others suggest that CLA supplements may cause inflammation or liver damage.

Overall, while CLA may have some effect on reducing body fat, the evidence is mixed, and there are potential side effects associated with CLA supplementation. As such, it may be safer to incorporate CLA-rich foods into your diet rather than taking CLA supplements.

CLA's impact on muscle health

Conjugated Linoleic Acid (CLA) is a naturally occurring fatty acid, similar to an omega-6 fatty acid, with purported health benefits for skin and weight loss. CLA is found in meat and dairy products, but only in low levels.

CLA has been shown to improve muscle health in a number of ways. Firstly, it can help to increase lean muscle mass. This is achieved by reducing body fat and increasing lean muscle mass, leading to improved muscle definition. Studies have shown that CLA supplementation, combined with a bodybuilding regimen, led to an increase in skin-fold corrected arm girth, leg press gains, and overall body mass, compared to a placebo group.

Secondly, CLA affects the intracellular signalling pathways in muscle metabolism and enhances physical performance. This may be due to changes in the muscle fibre type, as studies have shown that CLA supplementation can lead to an increase in muscle size and strength.

Thirdly, CLA has been shown to prevent and attenuate obesity. While most studies on CLA and obesity have focused on body fat reduction, some studies have demonstrated that CLA increases lean body mass and enhances physical performance.

Finally, CLA has been shown to improve liver health and boost the immune system. However, it is important to note that the safety of CLA supplements has been debated, with some studies suggesting that they may be harmful and cause inflammation or liver damage. Therefore, it is recommended to obtain CLA from natural dietary sources such as grass-fed beef and dairy products, rather than supplements.

Natural sources of CLA

Conjugated linoleic acid (CLA) is a fatty acid that can be obtained from food or supplements. CLA is mainly produced in the digestive tract of ruminant animals, such as cows, goats, sheep, and deer. The CLA produced by these animals is then stored in their muscle tissues and milk.

The top natural sources of CLA include:

• Grass-fed dairy products: Butter, plain yogurt, sour cream, cottage cheese, and milk are all good sources of CLA. The amount of CLA in dairy products can vary depending on the season and the diet of the animal. For example, milk from grass-fed cows at higher altitudes tends to have higher CLA content.
• Grass-fed meat: Beef from grass-fed cows is an abundant source of CLA. Fresh ground beef contains 4.3 milligrams of CLA per gram of fat. Lamb is another excellent source of CLA, with 4-19.0 mg of CLA per gram of fat content.
• Eggs: Eggs, especially from grass-fed chickens, are a good source of CLA. The CLA is found in the egg yolk and is preserved even after frying.
• Cheese: Fatty, ripened cheeses such as blue, Brie, Edam, and Swiss cheeses have higher CLA concentrations than other varieties.

While CLA supplements are available, it is important to note that the CLA in supplements is derived from linoleic acid found in seed oils and can have negative side effects. The CLA found in natural food sources has been shown to provide several health benefits, including a reduced risk of certain cancers, metabolic diseases, and heart disease.

CLA supplements' side effects

While CLA supplements are generally considered safe, some people may experience side effects such as an upset stomach, nausea, diarrhoea, and fatigue. In addition, CLA supplements have been linked to more serious health risks, such as increased inflammation, insulin resistance, and oxidative stress. They may also negatively impact liver health and lower HDL (good) cholesterol.

The potential side effects and health risks of CLA supplements are thought to be due to the different forms and higher doses of CLA found in supplements compared to natural food sources. The CLA found in supplements is made by chemically altering linoleic acid from vegetable oils, resulting in types of CLA that are not commonly found in nature. As such, it is recommended that individuals consult with a healthcare professional before taking CLA supplements, especially if they are considering doses higher than 6 grams per day.

CLA's role in improving overall health

CLA, or conjugated linoleic acid, is a natural fatty acid found in meat and dairy products. It is also available as a dietary supplement, often in capsule form, and is marketed primarily as a weight-loss aid. While CLA is a type of trans fat, it is not considered harmful to health as it is naturally occurring.

The role of CLA in improving overall health is a topic that has been widely studied, with some promising results. Here are some of the key benefits of CLA for improving overall health:

Weight Loss and Fat Burn

CLA has been shown to aid weight loss by boosting the metabolic rate. Studies have found that CLA supplementation can lead to modest reductions in body fat, with greater results when combined with regular exercise and a healthy diet.

Cancer Prevention

Some research suggests that CLA may help prevent certain cancers. Studies have shown that women who consume more dairy, a source of CLA, have a lower risk of breast and colorectal cancer. Additionally, scientists working with mice found that CLA appeared to reduce tumour growth.

Heart Health

CLA may also improve heart health by reducing bad cholesterol and protecting against atherosclerosis, the hardening of the arteries. This is likely due to CLA's ability to improve liver function, which in turn helps prevent plaque buildup by effectively metabolising fat.

Immune System

CLA is believed to strengthen the immune system due to its anti-inflammatory properties. It can help the body fight off infections and reduce the risk of developing allergies.

Blood Sugar Control

Some research indicates that higher CLA levels in the body are linked to a reduced risk of type 2 diabetes. CLA may help increase insulin sensitivity, making it easier for the body to shuttle glucose out of the blood and into muscle cells for energy.

Bone Strength

CLA has been shown to increase bone strength by improving the body's ability to absorb calcium and reducing the activity of osteoclasts, cells that break down bones.

While CLA has shown potential in improving overall health, it is important to note that the majority of the research has been conducted on animals, and human studies have shown less significant results. Additionally, CLA supplements have been associated with some adverse effects, including digestive problems, increased inflammation, and poor blood sugar control. Therefore, it is recommended to consult a healthcare professional before taking CLA supplements, especially for those with pre-existing health conditions.
