Millions more with obesity have lost weight and improved their health
This process occurs through several mechanisms: : Beneficial bacteria ferment fiber into butyrate, propionate, and acetate, which directly stimulate GLP-1 secretion Short-chain fatty acid production Mechanical stimulation : Fiber creates bulk that physically triggers hormone-releasing cells along your intestinal wall Nutrient sensing : Fiber slows digestion, allowing more time for L-cells to detect nutrients and release appropriate hormone levels Research demonstrates that consuming 25-35 grams of fiber daily can increase GLP-1 levels by up to 30% compared to low-fiber diets
The Swedish Obesity Subjects Study from 2007 evaluated over 4,000 patients in a prospective matched control study and demonstrated improvements in mortality, mostly due to reduction in death from cancer and myocardial infarction, of up to 2030% based on the degree of obesity prior to surgery with sustained outcomes at 1015 years of follow-up [21]
However, individualized assessment is necessary, and coordination with the oncology team is advisable for patients with active or recent cancer
