Objective:   This study evaluates the effect of serum vitamin D (Vit D) levels on weight loss in obese patients during an aerobic exercise program.

Material and Methods: The study included 88 participants with body mass index (BMI) ≥25 kg/m2. A serum level of 25(OH)D3 >30 ng/ml was accepted as normal, 20–29 ng/ml as insufficient and <20 ng/ml as deficient. The obese patients were classified into three groups based on a serum level of 25(OH)D3. All participants enrolled on an eight-week aerobic exercise program. The BMI, body fat percentage (BF%) and body fat mass (BFM) of the participants were measured before and after aerobic exercise.

Results: No statistically significant differences were identified between the groups in the first and last measured BMI, BF% and BFM values (p>0.05). The differences between the first and last measured weights, BMI, BF% and BFM were statistically significant within the groups (p<0.05).

Conclusion: Aerobic exercise can lead to weight loss in obese patients, although the level of serum Vit D has no effect on weight loss in obese patients engaged in aerobic exercise.
