Introduction:
Recent years have seen a significant increase in the incidence of diabetes mellitus, type 2 diabetes in particular, which closely correlates with the growing problem of overweight and obesity. The aim of the study was to compare eating habits among type 2 diabetic patients with varying body weight as well as to verify whether there was a relationship between dietary habits and the body mass index in these patients.

Material and methods:
The study was conducted in diabetology outpatient clinics. A total of 353 diabetic patients participated in the study. The study consisted of two parts, i.e. authors' questionnaire and anthropometric measurements.

Results:
The recommended number of 4–5 meals a day was declared by 48.6% of subjects with normal body weight, 50.3% of overweight and 48.4% of obese patients. Daily consumption of breakfast was confirmed by 77.1%, 73.9% and 77.8% of respondents, respectively. Daily consumption of whole-grain bread and coarse grits was mostly declared by subjects with normal body weight (62.8%), followed by overweight and obese patients (22.9% and 23%, respectively). Daily consumption of milk and fermented dairy beverages was reported by 24.3% and 15.7% of subjects with normal body weight, 22.3% and 14.7% of overweight patients as well as by 16.7% and 12% of obese patients, respectively.

Conclusions:
Eating habits among patients with type 2 diabetes are varied, with healthy eating habits dominating in subjects with normal body weight. A relationship was found between the patients’ BMI values and some of the eating habits as well as consumption rates of various food products.
