Brief Summary

Obesity is a chronic disease characterized by the excessive accumulation of adipose tissue that is harmful to health. Dietary habits modification through a caloric restriction, macronutrient distribution including linoleic and linolenic (n-6:n-3) polyunsaturated fatty acids (PUFAs) ratio, has been suggested for obesity management. It has been proposed that the optimal n-6: n-3 ratio should be between 1:1 and 5:1 to maintain a healthy balance. Purpose: Compare the effect of a diet n6:n3 ratio of polyunsaturated fatty acids with a group supplemented with n-3 PUFA on lipid profile in erythrocyte membrane, biochemical and inflammatory markers in subjects with obesity. Methods: 58 subjects were randomly divided into two groups: fish oil group and the placebo group. Anthropometric and biochemical data were evaluated, cytokine levels was performed using the Bio-PlexPro™ HumanTh17Cytokine Assays (MagPix) panel. The fatty acid profile quantification in the erythrocyte membrane was carried out by gas chromatography. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS) v.22 software.

Outcome Measures

Primary Outcomes (2)

  • The fatty acid profile quantification

    All the samples was performed in a Gas Chromatograph (GC) Agilent Technologies, 6850 network system coupled to an injector (Agilent Technologies, 7083 Series) with a column for fatty acids (Durabond, DB-23). flame ionization detector with helium as gas carrier (0.7 cm3 min-1) and a temperature ramp (110 °C - 220 °C).

    Mean change from baseline (0 Month) to end of treatment at 4th Month

  • Pro-inflammatory and Anti-inflammatory Cytokines profile in serum

    The pro-inflammatory and anti-inflammatory cytokines quantification were using Bio-Plex Pro™ Human cytokine Standard 17-Plex, Group I kit following the supplier's instructions, and the read was immediately by MAGPIX™ analyzer. The 17 cytokine include: IL1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12p70, IL-13, IL-15, IL17A, G-CSF, GM-CSF, INF-γ, MCP-1, MIP1α, TNFα. Units of measure in pg/ml.

    Mean change from baseline (0 Month) to end of treatment at 4th Month

Secondary Outcomes (10)

  • Changes in Weight

    At the baseline (0 Month) and 1st month, 2nd month, 3th month and the 4th month

  • Changes in Body Mass Index (BMI)

    At the baseline (0 Month) and 1st month, 2nd month, 3th month and the 4th month

  • Changes in Waist Circumference

    At the baseline (0 Month) and 1st month, 2nd month, 3th month and the 4th month.

  • Changes in Fat Mass

    At the baseline (0 Month) and 1st month, 2nd month, 3th month and the 4th month

  • Changes in Serum Glucose

    At the baseline (0 Month) and 1st month, 2nd month, 3th month and the 4th month

  • +5 more secondary outcomes

Study Arms (2)

n-3 supplementation group

EXPERIMENTAL

The nutritional strategy consisted a hypocaloric diet high in n-3. A 20% reduction by the total estimated energy through the Mifflin-St.Jeor formula was calculated, following a 50% to carbohydrates, 20% to proteins and 30% to lipids distribution. All participants received a balanced nutritional plan of omega-6/omega-3 close to 5:1 ratio, according to estimated energy. Additionally, a high omega-3 foods list was proportioned to emphasize their consumption during the study plus Omega 3 supplementation, the dosage was 2 capsules per day, containing 1.5 g of omega 3, of which 1000 mg were EPA and 500mg DHA. The omega 3 capsules were obtained from the same batch.
