Benefits and Research

Caffeine acts in the mid-brain, causing an increased release of dopamine (the “feel-good” hormone) and increased blood sugar usage. Mood, cognitive function and performance can be improved in certain populations because of the increased release of dopamine and blood sugar use.

One study showed increases in performance in highly trained swimmers when compared to moderately trained swimmers after consuming 250 mg prior to exercise. Another study tested nine competitive cyclists. Two trials were performed — one with and one without 330mg caffeine 60 minutes prior to training. The study found that the cyclists who ingested caffeine felt their effort was less, despite cycling longer (90.2 minutes with caffeine vs. 75.5 minutes without). The caffeine group also broke down more fat (118g with caffeine vs 57g without).


How much is too much?

A safe amount of caffeine for healthy adults is up to 400mg per day. Once ingestion spikes to 500-600mg, the following side effects may occur

  • insomnia
  • restlessness
  • irritability
  • upset stomach
  • tachycardia (increased heart rate)
  • muscle tremors


People with high blood pressure, heart problems or who already are experiencing sleep issues should avoid supplemental caffeine intake (coffee, energy drinks, etc.) Whenever your doctor prescribes medication, double check that caffeine supplementation doesn’t interfere with the medication. – (courtesy of the Mayo Clinic)

How to incorporate Caffeine for Fat Loss

Since most of us are not competitive cyclists or endurance athletes, the improved performance aspects of caffeine aren’t as relevant. What we can take away is that caffeine does increase our fat breakdown rate when we exercise (who doesn’t want that!). If no medical issues are present and assuming you’re a healthy adult, 100-150mg of caffeine before exercise can provide some increased fat breakdown from your workout. Talk with your practitioner to see if caffeine is right for you.
