Soluble fibre boosts satiety, aids weight loss: study

By Stephen Daniells

29/04/2008- Supplements of soluble dietary fibre may increase weight loss by boosting satiety, and has beneficial effects for cardiovascular health, suggests a study.

A soluble fibre supplement improved cholesterol levels in overweight and obese subjects, who also lost about four kilograms more than people in the placebo group over 16 weeks, report scientists in the British Journal of Nutrition.

The study taps into the burgeoning weight loss and management market, estimated to already be worth $7bn (€5.2bn) globally.

With 50 per cent of Europeans and 62 per cent of Americans classed as overweight, the food industry is waking up to the potential of products for weight loss and management.

The slimming ingredients market can be divided into five groups based on the mechanisms of action - boosting fat burning/ thermogenesis, inhibiting protein breakdown, suppressing appetite/ boosting satiety (feeling of fullness), blocking fat absorption, and regulating mood (linked to food consumption).

The researchers, led by Jordi Salas-Salvado from Saint Joan University Hospital in Reus, Spain, randomly assigned 200 overweight or obese patients to receive either a mixed fibre dose (three grams of Plantago ovata husk and one gram of glucomannan) twice or three times a day, or placebo for 16 weeks. The study was a parallel, double-blind, placebo-controlled clinical trial.

At the end of the study, the researchers report that weight loss 'tended' to be higher in both fibre groups (4.52 and 4.60 kg lost in the twice and three times a day group, respectively), compared to the placebo group (0.79 kg lost).

In addition, satiety was reported to be increase after consumed the fibre-rich meals.

Moreover, LDL cholesterol levels - a cardiovascular risk marker - decreased by 0.38 and 0.24 mmol/l in the twice and three times a day group, respectively, compared to a decrease of only 0.06 mmol/l in the placebo group, state the authors. Improvements in the ratio of total cholesterol to HDL-cholesterol and HDL to LDL were also reported.

"In conclusion, a 16-week dietary supplement of soluble fibre in overweight or obese patients was well tolerated, induced satiety and had beneficial effects on some CVD risk factors, the most important of which was a significant decrease in plasma LDL-cholesterol concentrations," wrote Salas-Salvado.

Effect of two doses of a mixture of soluble fibres on body weight and metabolic variables in overweight or obese patients: a randomised trial.

Salas-Salvad� J, Farr�s X, Luque X, Narejos S, Borrell M, Basora J, Anguera A, Torres F, Bull� M, Balanza R; for the Fiber in Obesity-Study Group.

The aim of the study was to compare the effect of the administration of a mixture of fibres on body weight-loss, satiety, lipid profile and glucose metabolism.

We included 200 overweight or obese patients in a parallel, double-blind, placebo-controlled clinical trial, who were randomised to receive, in the context of an energy-restricted diet for a period of 16 weeks, a mixed fibre dose (3 g Plantago ovata husk and 1 g glucomannan) twice (b.i.d. group) or three times daily (t.i.d. group) or placebo.

Weight change was the primary efficacy endpoint. Satiety, dietary compliance, lipid profile, glucose tolerance, insulin resistance and high-sensitivity C-reactive protein were secondary endpoints.

Weight loss tended to be higher after both doses of fibre ( - 4.52 (sd 0.56) and - 4.60 (sd 0.55) kg) than placebo ( - 0.79 (sd 0.58) kg); the differences in changes between groups were not statistically significant.

Postprandial satiety increased in both fibre groups compared to the placebo. The differences between groups in LDL-cholesterol levels were significant (P = 0.03), with greater reductions in the two fibre-supplemented groups ( - 0.38 (sd 0.10) and - 0.24 (sd 0.09) mmol/l in the b.i.d. and t.i.d. groups v. - 0.06 (sd 0.09) mmol/l in placebo group). A similar pattern was observed for changes in total cholesterol:HDL-cholesterol and HDL-cholesterol:LDL-cholesterol ratios.

Interventions were well tolerated and had no effects on HDL-cholesterol, glucose and insulin concentrations, glucose tolerance or high-sensitivity C-reactive protein.

In conclusion, a 16-week dietary supplement of soluble fibre in overweight or obese patients was well tolerated, induced satiety and had beneficial effects on some CVD risk factors, the most important of which was a significant decrease in plasma LDL-cholesterol concentrations.

4.6 kg = 10 lbs lost in a 16 week period in the fiber group. not bad.. less than a lb a week, but that is just by adding fiber.. so that's an easy change.

It seemed to lower LDL which is good.
