Taking a special fiber supplement for 6 months helped overweight people gain less weight than those who didn't take it, with much fewer people gaining a significant amount of weight.
Scientific Claim
Supplementing with 10g/day of inulin-propionate ester for 24 weeks significantly reduced weight gain in overweight adults, with only 4% of participants gaining ≥3% of baseline body weight compared to 25% in the control group.
Source Excerpt
“One of 25 participants gained ≥3% of their baseline body weight following inulin-propionate ester supplementation (4%), as compared with 6 of 24 participants (25%) in the inulin-control group (figure 3A, p=0.036).”
Evidence from Studies
Supporting Studies
Effects of targeted delivery of propionate to the human colon on appetite regulation, body weight maintenance and adiposity in overweight adults
The study directly compared weight gain between groups over 24 weeks, showing a statistically significant difference in the proportion of participants gaining ≥3% body weight. The randomised controlled design allows for comparison between intervention and control groups.
