How can proper bile function and the breakdown of bile acids contribute to weight loss?

„The UK has a weight problem - two thirds of adults are either overweight or obese - with one third of these obese, according to official heath surveys. Figures in Scotland and England are quite similar, but Northern Ireland has a lower obesity rate. While obesity rate in adults for both genders in England and Scotland is 29%, in Northern Ireland 27% of the population is obese.”

„Experts have predicted that by the year 2020 one third of the United Kingdom population could be obese[citation needed]. There are expected to be 11 million more obese adults in the UK by 2030. Adult obesity rates have almost quadrupled in the last 25 years.”

One of the most important functions of bile acids is the breakdown of fats and oils, dispersing them into tiny particles. They also activate lipase, a fat-breaking enzyme that speeds up the breakdown and absorption of fats / oils in the body.
Digestive problems caused by insufficient bile function can also lead to weight gain. If the body’s bile function is inadequate but a bile acid supplement is used to fill in the missing amount, then a change in lifestyle and additional physical exercise may contribute to successful weight loss.

„During the use of products containing bile acids, researchers observed that patients with excess weight and taking bile acids as part of their cure had lost weight. Evidence suggests that bile salts promote weight loss and the release of fat from adipose tissues.” Source: Nelegybeteg.hu
