ABSTRACT
Objetivo: describir los cambios en el peso, el porcentaje de grasa corporal y la ingesta de alimentos de personas con sobrepeso y obesidad, que consumieron 30 g diarios de linaza molida durante ocho semanas y reportar su tolerancia a este tratamiento. Materiales y metódos: se intervino un grupo de 10 participantes adultos con exceso de peso, voluntarios, quienes consumieron una dosis diaria de 30 g de linaza molida durante ocho semanas y a quienes se les solicitó que no modificaran su ingesta usual de alimentos y que no cambiaran su patrón de actividad física durante la intervención. Se midieron variables antropométricas, de consumo de alimentos y de actividad física en las semanas cero, cuatro y ocho, y se evaluó semanalmente la aceptación y tolerancia al tratamiento. Resultados: al finalizar la intervención los participantes no tuvieron cambios significativos en su peso (p=0,610), ni en su porcentaje de grasa corporal (p=0,866). No se presentaron efectos adversos. Conclusiones: el consumo de 30 g diarios de linaza molida durante ocho semanas, sin hacer reducciones en el consumo calórico y sin incrementos en la realización de actividad física, no permite reducciones de peso corporal en personas con exceso de peso.
Objective: To describe changes in weight, body fat mass and food intake in overweight and obese people, who consumed 30 g of ground flaxseed daily during eight weeks and to report the tolerance to this treatment. Materials and methods:It was an intervention study. A group of 10 overweight adults were selected to voluntarily consume 30 g of ground flaxseed through eight weeks. They were asked not to change their usual food intake and their physical activity routine during the intervention. , Food consumption, physical activity and anthropometric variables were measured at baseline, week four and week eight. Subject's tolerance to consumption of ground flaxseed was measured each week. Results: No significant changes in weight (p=0,610), and body fat mass (p=0,866) were observed. Participants did not report adverse effects. Conclusions: Intake of 30 g of ground flaxseed daily for eight weeks, without reductions of caloric intake and without increases in physical activity didn't show significant weight reductions in overweight individuals.
