Blueberry Bioactives

Improve insulin sensitivity with blueberries and you'll build muscle and lose fat faster. Here’s how.


It's often called the most anabolic hormone of all... and it's not testosterone. It's insulin.

But insulin is a two-faced "frenemy." How your body handles insulin can drive both muscle gain andfat gain. If you want to manipulate insulin to your advantage, then you need to increase your insulin sensitivity i.e. become less insulin resistant. This will result in less body fat storage and the ability to build muscle easier, especially if you incorporate peri-workout nutrition tactics in this insulin-sensitive state.

Sound good? Then you need to eat more blueberries.

A recent study showed that dietary supplementation with the bioactives from whole blueberries improved insulin sensitivity in insulin-resistant individuals. Basically, researchers gave fat (but non-diabetic) participants two blueberry smoothies per day for six weeks. At the end of the study, 67% showed a 10% or greater improvement in their insulin sensitivity.

Since more than half of the American population is predicted to have diabetes or be prediabetic by 2020 (which would amount to a gut-shot to the healthcare system) this is good news. For the physique-focused gym rat, eating blueberries or supplementing with blueberry concentrates could result in more muscle-building and less fat-building over time.

Adding fresh or frozen blueberries to a couple of protein shakes every day will help. Another option is to simply use Superfood, which contains freeze-dried organic blueberries with the same bioactivity as fresh.

Remember, insulin can be your friend or your enemy. It's up to you to tell it what to do. It looks like consuming blueberries is one way to do that.
