How long does it take to see results?

Most of the studies lasted a minimum of 12 weeks. It appears that a CLA supplement is safe to take for 24 months, though there did not seem to be additional benefits after 12 months.

What are good sources of CLA?

Research has shown the best source of CLA comes from fresh grass! And therefore from grass-fed beef. You can also find high levels of CLA in eggs and safflower oil. 

Studies suggest you can take 3 grams/day of CLA in three divided doses with meals for the fat-melting effect in its supplement form. As safflower has a higher content, you want to make sure your supplement uses safflower, not sunflower oil.   

One caveat is that if you have diabetes, make sure you check with your doctor as we are not sure what sort of effects CLA has on insulin sensitivity and resistance.

Fat Melter #2: Calcium Pyruvate

Our body naturally makes pyruvate when sugar is broken down to produce energy, a process called glycolosis.

How does it work?

Pyruvate seems to work by increasing your body’s use of fat as an energy source. Normally, your body first breaks down sugar, then protein and fat is saved until the end. Pyruvate appears to divert fat to be broken down sooner. The result is that the resting metabolic rate is raised, meaning you could feasibly be melting fat while watching TV if you have ingested the right amount of pyruvate. 

What kind of results can I expect?

Studies have shown a significant drop in weight, body fat and fat mass with pyruvate supplementation versus placebo, even in as short as 3 weeks; however, in that study, the dose was quite high, at 30grams/day, a dose that is often associated with gastrointestinal upset. The good news is that other studies have also shown that same effect can be achieved over 6 weeks with a smaller dose.
