Scientists Reveal the Hidden Reason Some People Stay Lean No Matter What They Eat

New Ivy League research points to a 'lean microbiome' that may explain stubborn belly fat and unexplained weight gain.

Lean for Good
Researchers have identified specific 'lean bacteria' species in the gut that may support healthy weight management.

If you have ever watched a friend eat whatever they want and stay slim while you seem to gain weight just by looking at a donut, new science suggests it is not about willpower. A recent study at King's College London examined 3,600 sets of twins where one was lean and the other overweight. The researchers found that the lean twins had a rich, diverse gut microbiome packed with 'lean bacteria' species, while the overweight twins had a less diverse microbiome dominated by different bacterial strains.

The Director of the Stanford University Microbiome Therapies Initiative called this 'the clearest evidence to date that gut bacteria can cause weight gain.' A growing body of research from Harvard, Yale, Johns Hopkins, and other world-class institutions now shows that repopulating your gut with the right kind of lean bacteria species may support a lean and healthy body. The challenge has always been finding a way to deliver these specific strains in a form that survives digestion and reaches the gut intact.

The Breakthrough That Changed Everything

Lean for Good is formulated with nine clinically-researched 'lean bacteria' species and Greenselect Phytosome, a caffeine-free green tea extract enhanced with patented absorption-boosting Phytosome technology. This advanced blend is designed to help support a healthy balance of gut bacteria, which researchers now link to healthy weight management. Each bottle provides a 30-day supply of two daily capsules.

With this research in hand, the team behind Lean for Good created a formula that combines these nine lean bacteria species with Greenselect Phytosome. Together, this blend is designed to help support the bacterial balance in your gut microbiome, the newly-discovered factor that may contribute to stubborn belly fat. In a 12-week clinical trial published in the British Journal of Nutrition, participants who consumed a specific lean bacteria species lost an average of 8.5% of belly fat, while the placebo group saw no such change.

I have tried everything for my belly fat, but this is the first thing that actually made a difference. After eight weeks, my clothes fit better and I feel lighter.

I was skeptical at first, but after six weeks of taking Lean for Good I noticed my belly was flatter and I had more energy. The bloating I used to have after meals is gone. I just ordered my second bottle.
