Cardarine VS Ostarine | Which One Is Better For Fat Loss

Table of Contents

Let’s get one thing out of the way first – we’re not comparing two SARMs – as it is commonly assumed that Cardarine is a SARM.

No, Cardarine is actually a PPAR delta receptor agonist that induces changes in how the liver processes its energy source.

Cardarine VS Ostarine

With that out of the way, let’s take a look at how these two compounds fare up against each other when it comes to fat loss during a cut.

Ostarine does help with fat loss, but indirectly, through increasing the basal metabolic rate of the end user.

In a typical eight-week cycle, you will lose up to 5% of your total body fat, if you stick to your diet and exercise regime.

Professional bodybuilders usually take Ostarine not for its efficiency in fat loss, but for the fact that it prevents muscle loss during a cut. This will become important in a later chapter.

Cardarine for fat loss

Cardarine increases endurance, especially during cardio, which helps users break their plateaus at the treadmill.

This causes fat loss as you’re expending more energy and given the fact that Cardarine itself makes the liver switch its food source from glucose to fatty acids, you’ll be turning into a fat-burning machine in no time!

Cardarine also increases oxidative capacity in the muscles, which leads to more calories to be expended while doing the same type of exercises.

In an eight-week cycle, with proper dieting and exercises routines, you can lose a stunning 7 to 8% of your total body fat.

Of course, if you already have a low body fat percentage, this rule is somewhat mitigated.

Cardarine VS Ostarine for fat loss

If I had to pick a winner between the two, I would definitely go for Cardarine. It is basically molding your body in a way that makes it lose a ton of fat.

Even if you aren’t motivated and hate cardio, the increased endurance will lead to a change of heart, at least that’s what it did in my case – running started suiting me and I became one with the flow.

On the other hand, Ostarine can also help you lose fat, but that is not it’s primary objective. As previously mentioned, its main goal is to preserve muscle in your body, while indirectly causing fat loss through increasing your basal metabolic rate.


Cardarine is the obvious winner when it comes to inducing fat loss in the end user. It was practically made to cause fat loss and it’s very potent at doing just that.

I think that combining Ostarine and Cardarine is the best way to go forward and that taking these compounds individually is basically ignoring the amazing synergy those two have.

All in all, if you want the maximum amount of fat loss without losing any muscle, go for the stack outlined above!
