Brief Summary

Conjugated linoleic acid or CLA, is one of the food supplements that could be found in meat, fats, and dairy products of ruminants which has been fed grass not on grains. CLA has shown anti-cancer, anti-obesity, and anti-inflammatory effects in several animal modules, but the results of the human studies were not consistent. Also, a very limited number of studies looked at the CLA effect on the respiratory system. The study will look at the effect of 12 weeks of supplementation of conjugated linoleic acid on obesity markers, lung functions, lipid profile, and inflammation in overweight and obese women in a double-blind randomized control trial. The study looked at the inflammation using different approaches, where it looked at the expression of adhesion molecules on the proinflammatory monocytes as well as it analysed the expression of the stress proteins Heat-shock proteins (HSPA1A and HSPB1)on the PBMCs.

Outcome Measures

Primary Outcomes (8)

  • The change in body weight from baseline to 12 weeks

    Body weight (Kg) will be measured using Bioelectric impedance technique (Tanita MC-780)

  • The change in total body fat from baseline to 12 weeks

    total body fat (Kg) will be measured using Bioelectric impedance technique (Tanita MC-780)

    0, 6, 12 Weeks

  • The change in percentage body fat from baseline to 12 weeks

    Percentage body fat will be measured using Bioelectric impedance technique (Tanita MC-780)

    0, 6, 12 Weeks

  • The change in Lean body mass from baseline to 12 weeks

    Lean body mass (Kg) will be measured using Bioelectric impedance technique (Tanita MC-780)

    0, 6, 12 Weeks

  • The change in percentage lean body mass from baseline to 12 weeks

    Percentage lean body mass will be measured using Bioelectric impedance technique (Tanita MC-780)

    0, 6, 12 Weeks

  • The change in waist circumference from baseline to 12 weeks

    Waist circumference will be measured by cm using the tab

    0, 6, 12 Weeks

  • The change in waist to hip ratio from baseline to 12 weeks
