CLA for Fat Loss: The Basics

What is CLA, or conjugated linoleic acid, and what does it have to do with fat loss? If your goal is to lose fat and get lean, then you should know about CLA, one of the most popular weight loss supplements in the entire world. This naturally occurring fatty acid is one of very few supplements with objective scientific evidence showing that it helps people burn extra body fat. This supplement comes in a number of forms, but the one I prefer is a gel cap that’s easy to swallow and convenient to keep in a purse, backpack, or desk drawer. CLA has few known side effects, and used responsibly it has been shown to make a difference for those of us trying to lose body fat.

The basic component of CLA is an omega-6 fatty acid called lineolic acid. It’s found in grass-fed beef and poultry, as well as in various vegetable oils. The “conjugated” part of conjugated linoleic acid has to do with the molecular structure of the supplement, which makes a big difference in the way it’s available for our cells to use (metabolize) it. While the double bonds in CLA make it a kind of trans fat, it’s important to recognize that it’s not a man-made trans fat. Since it occurs naturally in beef and dairy, the trans fat of CLA is not considered harmful in the way that the man-made variety is.

My Experience with CLA Supplements

Three years ago I decided to try to lose fat through diet and exercise. I didn’t have a whole lot of excess weight at the time – my total goal was to lose 20 pounds. I began counting the calories in the food I ate and keeping track of the calories I burned through exercise. My general goal was to burn between 200 and 300 more calories a day than I consumed, which would put me in a nearly constant calorie deficit and force my body to slowly burn its stores of fat. At this rate, my progress would be slow and steady, and I would be in a good position afterward to maintain my new weight by eating and burning the same number of calories every day -- not that hard to do!

Approaching my fat loss plan this way, I calculated that I would be able to lose one pound about every two weeks. Further, I wanted to keep whatever muscle I had and burn as much fat as possible, so I included consistent weight-lifting along with running/walking. Finally, I looked into supplements. I didn’t want to be a sucker and buy supplements that didn’t work or, worse, could actually damage my health. Again and again, I came across articles on conjugated linoleic acid. There was actual scientific evidence, supported by legitimate studies, that showed small but significant fat-burning properties. I bought a supply online and started taking them every day.

My Results with CLA Supplements

I did lose the weight I had wanted to lose, although it took a little longer than I thought it would: losing a little less than 2 pounds a month, I lost 20 pounds in less than a year. Most of that weight was fat, and I could see a big difference in the mirror. To make sure that I was losing fat and not losing muscle, I bought an affordable body fat scale, also known as a body composition or “smart scale." These scales are an essential part of losing fat and not muscle, because they can tell you what percentage of your body is fat, water, and muscle. Keeping track of weight loss with a body fat scale helped me make sure I wasn't just losing water weight, or, worse, losing muscle when I was trying to lose only fat. This was really important to me, since I worked hard to keep whatever muscle I had!

I can’t say for sure that taking conjugated linoleic acid helped me lose fat, but I did lose fat while taking CLA. The way I look at it, it certainly didn’t hurt – I lost the fat I wanted to, and the supplement may have had something to do with it.

Fatty Acids to Lose Fat?

Since this substance is a “fatty acid,” you may be inclined to think that this supplement is going to add to the fat that you’re consuming. While technically this is true, the amount of actual fat in a supplement dose is small, and in any case the kind of fat that we’re talking about is not the kind that makes you fat. On the contrary, research shows that CLA actually leads your body to burn fat. So in this way, not all fats are created equal, and the kind in supplements like these are actually good for you. The fat-burning qualities of Conjugated Linoleic Acid supplements are what have made it such a popular weight-loss supplement.

The CLA Controversy

There are a few sources that dispute the effectiveness of CLA in fat loss, and I read up on these carefully before deciding to give it a try. One good source for the opposing viewpoint about CLA is a Men’s Journal article that questions the full effectiveness of the supplement for fat loss. At issue is the source from which the omega-6 fatty acid in these supplements is derived. In the human diet, the best source for omega 6 is in grass-fed beef and poultry; in the capsules that contain CLA, it's derived from safflower oil and other plant-based sources. There is good evidence that natural, animal-based conjugated linoleic acid will in fact aid in fat burning, but similar research on plant-based sources is not as thorough. That’s not to say it doesn’t work, just that the evidence isn’t as robust as it is for the animal tissue sources.

Another factor in the effectiveness of taking CLA as a supplement, rather than as a component of whole foods in your natural diet, is the array of incidental nutrients and compounds that come along with the fatty acids and may play a part in their effectiveness. Vitamins and minerals such as calcium, magnesium, potassium, omega-3s, and vaccenic acid are related to CLA conversion. Without them, your body may not reap the full fat-burning benefits. Seeing this, I decided to switch to grass-fed beef and poultry, and to add that to my CLA supplementation. I reasoned that this would give me the best of both worlds.

Final Thoughts

While CLA did work for me, I was also careful about my diet and working out 3-4 times a week. This supplement, like all supplements, is unlikely to make a big difference in your fat-burning efforts without an associated commitment to eating well, cutting calories, and staying active. If we’re consistent, strong, and smart, we can reach our goals with or without the boost of supplements like conjugated linoleic acid.

      I keep on the consistent path of eating right, exercise and attitude to combat the effects of age and weight gain. I will look into this option next time I shop for my supplements. Thanks for the tip.
