Objectives: To evaluate eating habits and leisure time physical activity in a sample of overweight or obese individuals. Patients and method: Data were collected from 90 patients (80% females) aged 34.8 ± 11.3 years with a mean body mass index (BMI) of 38.9 ± 7.5. To assess intake, we used a combination of 24-hour intake recall and a dietary record of 4 non-consecutive days. Patients were considered to be underreporters when their intake was less than 1.28 x BMR (basal metabolic rate obtained according to World Health Organization criteria). Total energy intake, energy from different nutrients, and energy from different food groups were studied. To evaluate leisure time physical activity, the Minnesota Leisure Time Physical Activity Test (validated to Spanish) was used. Results: The percentage intake of carbohydrates, proteins and fats in our sample was 41.7%, 15.4% and 40.7%, respectively. No differences were found in the energy content of the diet or in nutrient intake between patients with different degrees of obesity. Only one of the food groups evaluated, sugars, showed a difference in intake. Physical activity was significantly higher in women. Although there was a trend to an inverse association between physical activity and the degree of obesity, this trend was not statistically significant. Conclusions: Few difference in eating habits were found in relation to BMI. Lower leisure time physical exercise tended to correlate with higher degrees of obesity.
