Lose fat with acai

Supplementation with acai - scientific name Euterpe oleracea - might reduce the amount of body fat you're carrying, a Brazilian animal study published in PLoS One suggests.

Study
The researchers, working at State University of Rio de Janeiro, experimented with four groups of mice for 12 weeks. A first group got standard food [Control], and a second group was given extra fat in their food [High Fat; HF]. Two other groups of mice, of which one got the standard food [ASE] and the other extra fat [HF+ASE], were given acai extract via a tube every day.

The researchers used an extract made from the seeds of acai. This consisted mainly of anthocyanidin polymers. The human equivalent of the dose, based on a person weighing 80 kg, was about 2.4 g extract per day.

Results
It doesn't take a genius to work out that the animals on the high fat diet [HF] put on more weight than the ones on standard feed [Control]. Supplementation with acai [ASE] largely prevented the increase in bodyweight.

The mice in the high fat group built up bigger fat reserves, but the increase was noticeably lower in the high fat + acai group. What's interesting in the table above is that the acai also had a significant effect on the size of the fat reserves in the mice that got standard feed. You don't see an effect like this so often in animal studies. And that effect is really the reason why we're writing this post.

The figures above indicate how acai probably works. The extract activated the enzyme AMPK.

The high fat feed increased the concentration of 'bad cholesterol' LDL in the blood. The acai supplement reduced the increase.

The figure above reveals how acai improved the cholesterol. The supplement boosted the synthesis of the transport proteins ABCG5 and above all ABCG8 in the liver. These proteins are responsible for removing cholesterol from the body via bile acid.

"Larger multicenter trials with longer term follow-up interventions in more homogenous chronic fatigue syndrome populations are warranted."
