NCT00912197

Brief Summary

This study seeks to look into the effects of oligofructose supplementation on appetite, energy intake, and body weight and body composition in overweight subjects. Compared to a placebo product (cellulose) oligofructose is hypothesised to suppress hunger and thereby reduce food intake moderately leading to a decrease in body weight.

Outcome Measures

Primary Outcomes (5)

  • Subjective Appetite Ratings in Hunger Compared to Baseline

    Hunger was assessed by visual analogue scales (Each scale is 10cm in length with words anchored at each end, expressing the most positive (Minimum score = 0 cm and means no hunger) and the most negative rating (Maximum score = 10 cm and means very hungry). Compared to baseline after treatment at 56 days

    Baseline, 56 days

  • Subjective Appetite Ratings in Fullness Compared to Baseline

    Fullness are assessed by visual analogue scale, 10 cm in length with words anchored at each end, expressing the most positive (feel full: maximum Score=10cm) and the most negative rating (feeling empty: Minimum Score = 0cm), values at baseline and after treatments at 56 days

    Baseline, 56 days

  • Body Weight

    Baseline, 56 days

  • Energy Intake

    Energy intake was assessed by 7-days food diary at baseline and last week of treatment, diaries were analysed by Dietplan6 software. The values in the table represent the Energy intake as measured over the whole week (as opposed to reporting the Energy intake per day based on the 7 day data).

    Baseline, 56 days

  • Gut Hormone PYY

    Total PYY concentrations were quantified using specific and sensitive in-house radio-immunoassays as previously described.

    baseline (Day 0) and post-supplementation (Day 56)

Secondary Outcomes (7)

  • Body Composition

    Baseline, 56 days

  • Imaging of Total Adipose Tissue

    Baseline, 56 days

  • Plasma Short-chain Fatty Acids Concentrations After Treatment

    Baseline, 56 days

  • Inflammatory Markers

Study Arms (2)

Oligofructose

EXPERIMENTAL

Participants received 10g of Oligofructose powdered supplements in sachets each containing 10 g dietary fiber) three times per day. Volunteers were instructed to take the supplement with their main meals.The 8-week supplementation period took place between visits 3 and 4 and included a 2-week run-in period to allow the bowel to adapt to the 30 g of dietary fiber.

Dietary Supplement: Oligofructose

Cellulose and maltodextrin

PLACEBO COMPARATOR

Participants received 10g of Cellulose powdered supplements in sachets each containing 10 g dietary fiber) three times per day. Volunteers were instructed to take the supplement with their main meals. Maltodextrin was added to the cellulose supplement. The 8-week supplementation period took place between visits 3 and 4 and included a 2-week run-in period to allow the bowel to adapt to the 30 g of dietary fiber.

Dietary Supplement: Placebo

Interventions

OligofructoseDIETARY_SUPPLEMENT

Participants will be asked to consume 30g of oligofructose daily for six weeks after a 2-week run-in.

Oligofructose
PlaceboDIETARY_SUPPLEMENT

Participants will be asked to consume 3 doses (a total of 30g dietary fibres) of the placebo product daily for six weeks after a 2-week run-in

Cellulose and maltodextrin
