Hypothesis
This study aimed to evaluate the effectiveness of treating severe obesity in hospitalized patients using very low-calorie diets and clinical support.
Conclusion
The study suggests that inpatient treatment with low-calorie diets and lifestyle changes significantly improves weight and metabolic health in patients with severe obesity.
Supporting Evidence
- Three months of hospitalization led to significant reductions in weight, BMI, and fat mass.
- Men lost more weight and fat mass than women during the treatment.
- Elderly patients had smaller reductions in BMI and fat mass compared to younger patients.
- After 6 months, the reductions in weight and fat mass nearly doubled those observed at 3 months.
- Patients showed significant improvements in glucose, lipid, and inflammatory markers.
Takeaway
