  Purpose

The objective of the Orlifat trial is to investigate if dietary fibres from linseeds and dairy calcium (Capolac ®) may reduce gastrointestinal side effects related to increased fecal fat content, induced by treatment with Alli® (orlistat). Secondly, effect on food intake, anthropometry, Quality of Life and cardiovascular risk markers will be evaluated. The trial is designed as a randomised 2 x 2 factorial 13-weeks parallel intervention, in which 72 obese participants will be randomised to supplementation with flaxseed fibres and/or dairy calcium concentrate (Capolac) in addition to treatment with Alli ®:

  1. Alli® (60 mg t.i.d) plus placebo (rice flour)
  2. Alli® plus 5 g flaxseed fibers
  3. Alli® plus 1200 mg Ca from Capolac
  4. Alli® plus 5 g flaxseed fibers and 1200 mg Ca from Capolac

Secondary Outcome Measures:
  • Total fecal fat excretion [ Time Frame: week 0 and 4 ] [ Designated as safety issue: No ]
    Average total fecal fat excreted during five days in week 0 and week 4

  • Total, LDL and HDL cholesterol [ Time Frame: baseline and 12 ] [ Designated as safety issue: No ]
  • Ratings of quality of life [ Time Frame: baseline, week 0, 2, 4, 8 and 12 ] [ Designated as safety issue: No ]
    Questionnaire used to assess quality of life related to obesity and treatment thereof

  • Body weight [ Time Frame: baseline, week 0, 2, 4, 6, 8, 10 and 12 ] [ Designated as safety issue: No ]
  • Waist and hip circumference [ Time Frame: Baseline, week 0, 2, 4, 6, 8, 10 and 12 ] [ Designated as safety issue: No ]
  • food intake [ Time Frame: week 0 and 4 ] [ Designated as safety issue: No ]
    Intake of total fat and energi estimated using 7d weighed food records

  • Habitual intake of dietary fiber and calcium [ Time Frame: baseline ] [ Designated as safety issue: No ]
    Habitual intake of dietary fiber and calcium estimated using food frequency questionnaires
