Overview
Brief Summary
The aim of the study is to estimate the effectiveness of two different exercise programs combined with the Mediterranean diet versus diet alone on inflammatory status in subjects aged 18-65 years with obesity (BMI>30) and Non-Alcoholic Fatty Liver Disease (NAFLD) (CAP >248 dB/m).
Detailed Description
The main objective of the study is to estimate the effect of two exercise programs of different type and intensity combined with a Low Glycaemic Index Mediterranean Diet (LGIMD) compared to diet alone on the systemic inflammation index (SII) and biomarkers related to the inflammatory state: TNF-alpha; IL-1, IL-6, IL-10, CK-18, PCR and VES, in patients with obesity and NAFLD aged 18-65 years after a 4-month intervention. The secondary objectives are: to assess whether the adoption of the two exercise programs of different types and intensities associated with an LGIMD compared to diet alone in patients with obesity and NAFLD can significantly modify body composition, inhibiting the risk of sarcopenia, in turn, favored by NAFLD, improve physical efficiency (fitness), understood as cardio-respiratory fitness muscular strength and flexibility, may also lead to improvements regarding the gut microbiota, in terms of abundance of microbial taxa, by studying, starting from the data obtained from the 16S, the metabolic pathways of the microbiota and fecal metabolome, as well as Quality of Life, by filling in specific questionnaires, and the evaluation of the fatty acid profile of erythrocyte membranes. The two different types of exercise will be: - outdoor walking, understood as a moderate-intensity aerobic exercise, carried out 4 times a week, for a duration of 60 minutes for 4 months; - High-Intensity Interval Training carried out 3 times a week, for a period of 50 minutes at a time for 4 months in a gymnasium affiliated with the organization. The diet will be the same for all project participants and will follow advice based on the Low Glycaemic Index Mediterranean Diet. All subjects will be followed by specialized personnel regarding both diet and exercise.

Outcomes
Primary Outcomes
The effect of diet and exercise on systemic inflammatory status
Time Frame: at baseline and day120
To estimate the effect of two exercise programs of different types and intensity combined with a Mediterranean Low Glycaemic Index Diet (LGIMD) compared to diet alone on the systemic inflammation index (SII) and biomarkers related to the inflammatory state: C-reactive protein (CRP) and Erythrocyte sedimentation rate (ESR) were measured after venous blood sampling. Proinflammatory (TNF-alpha; IL-1, IL-6, CK-18) and anti-inflammatory (IL-10) cytokines will be measured using commercially available ELISA tests for each.
Secondary Outcomes
- The effect of diet and exercise on the fatty acid profile of erythrocyte membranes(At baseline and day 120)
- The effect of diet and exercise on body composition(At baseline, day 60, and day 120)
- The effect of diet and exercise on the gut microbiota(At baseline and day 120)
- The effect of diet and exercise on quality of life(At baseline and day 120)
- The effect of diet and exercise on the peptides of Integrity Intestinal Barrier(At baseline and day 120)
- The effect of diet and exercise on the risk of sarcopenia(At baseline and day 120)
- The effect of diet and exercise on the Intestinal dysbiosis(At baseline and day 120)
