NCT05275608

Brief Summary

VLCKD has showed to be an impactful diet on several metabolism aspects and has proven to be useful for preventing and treating diabetes mellitus type 2, overweight, chronic inflammation and fatty liver. For this reason, the aim of this pilot study is to examinate the potential effect of a VLCKD on a group of patients that contemporarily have DM2, obesity and Non alcholic fatty liver disease (NAFLD), comparing the results with an ipocaloric diet based on Mediterranean Principles and Italian LARN (SINU 2014). This study will consider several interrelated outcomes such as anthropometric data, hematochemical and hormonal parameters, questionnaires, stool microbiota and omics, blood microvescicles, urine tests, instrumental tests (DXA, BIVA, ecographies), biopses and functional tests. 40 subjects will be evaluated and divided in two groups of 20 (VLCKD) and 20 (MedDiet).

Study Arms (2)

VLCKD

EXPERIMENTAL

20 Patients recruited from our endocrinology department that will keep the same medical visits frequency and drugs and accept to be randomized to one of the two groups. Inclusion criteria: * Age 25-65 * BMI 30-40 mg/m2 * NAFLD * DM2 drug-treated (metformin, SGLT2 inhibitors, GLP-1 analogues, DPPIV inhibitors, insulin) and HbA1c \> 7 and \< 10 %.

Dietary Supplement: VLCKD diet with replacing meals

Hypocaloric Mediterranean Diet

ACTIVE COMPARATOR

20 Patients recruited from our endocrinology department that will keep the same medical visits frequency and drugs and accept to be randomized to one of the two groups. Inclusion criteria: * Age 25-65 * BMI 30-40 mg/m2 * NAFLD * DM2 drug-treated (metformin, SGLT2 inhibitors, GLP-1 analogues, DPPIV inhibitors, insulin) and HbA1c \> 7 and \< 10 %.

Behavioral: Hypocaloric mediterranean Diet

Interventions

Patients will receive an accurate teaching + brochure on VLCKD diet from an expert dietician and freely receive the correct amount of supplements provided from Labotaoire Therascience (4 or 5 meals). The supplements contain (in total) between 600 and 800 kcal, mainly fats, 1,2/1,5 g/body weight of proteins, very low amount of charbohydrates (\<30/40g/die), 10-20g fibers, + minerals and vitamins covering the needings of patients. After 6-8 weeks, 1 meal will be replaced with a natural dish rich in proteins.

VLCKD

Patients will receive an accurate teaching + brochure on an hypocaloric Mediterranean style diet (LARN 2014) from an expert dietician. Patients will follow the istructions on grams and foods to eat. The calories will be around minus 400-500 kcal from energy requirement (measured by indirect calorimetry \* physical activity score).

Hypocaloric Mediterranean Diet
