Frequently Asked Questions
We have long recognized the significance of incorporating healthy fats into our diets. They play a crucial role in enhancing cholesterol levels, supporting brain function, and even improving mood and mental health.
Recent studies have also highlighted the potential of healthy fats in aiding weight loss.
So, what exactly are considered healthy fats? I have always recommended plant-based fats like olive oil, coconut oil, nuts, and avocado as top choices. These four food options can be enjoyed liberally, offering health benefits with every serving. Moreover, apart from their fat content, these foods are rich in various essential nutrients.
For those seeking weight loss benefits, there is a specific type of animal fat that can provide an additional advantage...
Certain animal fats contain CLA (conjugated linoleic acid), which has been extensively studied and shown to offer a range of health perks. CLA gained attention approximately 25 years ago as a significant discovery.
Despite its promising benefits, CLA has not been widely recommended as a top-tier supplement by most health experts.
However, perhaps it is time for a reassessment. Research has indicated that CLA can contribute to reducing tumor size, reversing atherosclerosis, aiding weight loss, and lowering body mass index (BMI). It is particularly popular among bodybuilders for its fat-burning properties and ability to promote lean muscle growth.
So, what exactly is CLA?
CLA is a naturally occurring fatty acid present in ruminant animals such as cows, sheep, and goats. When you consume meat and dairy products from these animals, you are ingesting CLA. It is essential to note that for significant CLA content, animals should be grass-fed.
The uniqueness of the CLA molecule lies in its 28 different forms, known as isomers. These isomers appear to target various health conditions in distinct ways.
For instance, some isomers aid in reducing tumors and promoting muscle growth, while others possess anti-cancer properties and discourage fat accumulation.1
Several studies, both on animals and humans, have explored the potential of CLA in supporting weight loss, with many demonstrating positive outcomes.
Researchers from Japan reviewed 18 studies on CLA conducted between 2000 and 2012, with 72% of them indicating improvements in metrics like BMI, body fat percentage, weight, and lean muscle mass with CLA supplementation.2
One study focused on overweight or obese individuals to evaluate the benefits of CLA. The participants were divided into two groups - one receiving CLA supplementation over six months and the other group receiving a placebo, with no changes in their diet or exercise routines.3
After six months, the group taking CLA had decreased their body fat mass by 3-6%. While this may not be groundbreaking, this reduction can be beneficial when combined with other weight loss strategies. Researchers suggest that continued use of CLA could potentially lead to further fat loss, although this remains theoretical.
As mentioned earlier, the source of CLA is crucial...
CLA is complex and requires specific bacteria found only in ruminant animals for its production. To maximize the benefits of CLA, opt for meat and dairy products from grass-fed cows, sheep, and goats.
Ruminant animals have stomachs with four chambers, with the rumen hosting bacteria essential for digesting grass, leading to the production of CLA as a byproduct.
The diet of the animal significantly affects the CLA content. A study examining CLA levels in cow's milk revealed a substantial difference.
Cows that graze on pasture have 500% more CLA in their milk fat compared to cows fed a standard diet that includes corn products and other supplements.4
It is important to note that corn is not a natural part of a cow's diet; grass is. Milk and meat from grain-fed cows can be considered processed foods, as the processing begins while the animal is alive.
When it comes to dairy products, choosing full-fat options is essential as CLA is primarily found in the animal's fat. Reduced-fat and fat-free dairy products are not natural choices. While debates continue regarding their health implications, opting for whole milk over reduced-fat options is generally recommended.
According to research from Penn State, here are the top 10 foods rich in CLA content, listed from highest to lowest:5

While the discussion on meat and dairy consumption continues, selecting the most nutritious options, such as grass-fed products, is advisable if you include them in your diet.
Personally, I include meat in my diet several times a week, preferably from grass-fed and organically raised sources. Additionally, I enjoy dairy products like cheese, milk, and butter, although moderation is key.
Some experts advise caution with these "third rail" foods. If you experience difficulties digesting milk, it may be best to avoid it. While individuals of European descent usually tolerate dairy well, other ethnicities, particularly East Asians, may face challenges with dairy consumption.
