Highlights
- •The effect of two low-energy Mediterranean diets on body weight was explored.
- •The Mediterranean diets differed for the pasta intake (low or high).
- •Body weight reduction was observed in both groups after 6-month intervention.
- •Both diets improved anthropometrics and physiological parameters and dietary habits.
- •Low-energy Mediterranean diets could be beneficial strategies for weight loss.
Abstract
Background & aims
The effect of pasta consumption within a low-energy Mediterranean diet on body weight
regulation has been scarcely explored. This paper investigates the effect of two Mediterranean
diets, which differed for lower or higher pasta intake, on body weight change in individuals
with obesity.
Methods & Results
Forty-nine volunteers finished a quasi-experimental 6-month two–parallel group dietary
intervention. Participants were assigned to a low-energy high pasta (HP) or to a low-energy
low Pasta (LP) group on the basis of their pasta intake (HP ≥ 5 or LP ≤ 3 times/week).
Anthropometrics, blood pressure and heart rate were measured every month. Weight maintenance
was checked at month 12. Body composition (bioelectrical impedance analysis, BIA),
food intake (24-h recall plus a 7-day carbohydrate record) and the perceived quality
of life (36-item short-form health survey, SF-36) were assessed at baseline, 3 and
6 months. Blood samples were collected at baseline and month 6 to assess glucose and
lipid metabolism. After 6-month intervention, body weight reduction was −10 ± 8% and
−7 ± 4% in HP and LP diet, respectively, and it remained similar at month 12. Both
dietary interventions improved anthropometric parameters, body composition, glucose
and lipid metabolism, but no significant differences were observed between treatment
groups. No differences were observed for blood pressure and heart rate between treatments
and among times. HP diet significantly improved perception of quality of life for
the physical component.
Conclusions
Independent of pasta consumption frequency, low-energy Mediterranean diets were successful
in improving anthropometrics, physiological parameters and dietary habits after a
6-month weight-loss intervention.
This trial was registered at clinicaltrials.gov as NCT03341650.
