Gastric bypass alters gut bacteria leading to weight loss
Torso rotation strength training was initially thought to work because it corrected a strength asymmetry. This concept made a lot of sense but further research found that all children have a strength asymmetry, not just those with Scoliosis. The upshot is that TRS probably works for a different reason that isn't yet clear.
In the world of biology that's just another day at the office. Scientists find treatments that work, but quite often they don't know why they work. Sometimes the most obvious explanations turn out to be wrong.
Case in point: After weight-loss surgery, new gut bacteria keep obesity away
This kind of discovery not only helps to explain why over 35% of American adults are obese but it will lead to safer, less invasive ways to treat it.
So the question is why does torso rotation work? Nobody really knows why a simple exercise could be so effective but the fact that it helps gives scientists a clue as to why roughly 3% of children around the world suffer from Scoliosis.

Case in point: After weight-loss surgery, new gut bacteria keep obesity away
The logic behind weight-loss surgery seems simple: rearrange the digestive tract so the stomach can hold less food and the food bypasses part of the small intestine, allowing fewer of a meal's calories to be absorbed. Bye-bye, obesity. A study of lab mice, published on Wednesday, begs to differ. It concludes that one of the most common and effective forms of bariatric surgery, called Roux-en-Y gastric bypass, melts away pounds not - or not only - by re-routing the digestive tract, as long thought, but by changing the bacteria in the gut. Or, in non-scientific terms, the surgery somehow replaces fattening microbes with slimming ones.
For many obese patients, particularly those with type 2 diabetes, gastric bypass has succeeded where nothing else has. Severely obese patients routinely lose 65 to 75 percent of their excess weight and fat after the operation, studies show, and leave their diabetes behind. Oddly, however, the diabetes remission often occurs before significant weight loss. That has made bypass surgeons and weight-loss experts suspect that Roux-en-Y changes not only anatomy but also metabolism or the endocrine system. In other words, the surgery does something besides re-plumb the gut. That "something," according to previous studies, includes altering the mix of trillions of microbes in the digestive tract. Not only are the "gut microbiota" different in lean people and obese people, but the mix of microbes changes after an obese patient undergoes gastric bypass and becomes more like the microbiota in lean people.
