Brief Summary
Background. The prevalence of type 2 diabetes mellitus (T2D) in the world is constantly increasing. Treatment of T2D is complicated by arterial hypertension and obesity (metabolic syndrome - MS). Cardiovascular complications are the main cause of death in patients with MS. Objective weight loss improves clinical and laboratory parameters in patients with T2D and hypertension. Purpose: To study lifespan, glycemic and lipid metabolism, quality of life, and cost-effectiveness of pharmacologic, surgical, and dietetic weight loss methods in obese patients with MS at 24 weeks in a comparative clinical trial. Methods:
- 1.st stage - Study design: An open pilot prospective clinical trial. The study included 71 adult patients with T2D and hypertension for the Ramadan fast's (RF) weight loss.
- 2.nd stage - Study design: A 24-week open label, prospective, multicenter, comparative clinical trial with the intention-to-treat analysis.
- 3.at least three articles and/or reviews in peer-reviewed scientific publications indexed in the Science Citation Index Expanded of the Web Of Science database and/or having a Cite Score percentile in the Scopus of at least 50;
- 4.at least 1 patent for an invention (including a positive decision on it).

Outcome Measures
Primary Outcomes (7)
Weight
weight in kilograms
Baseline, 24 weeks
Body mass index
weight and height will be combined to report BMI in kg/m\^2
Baseline, 24 weeks
Fat mass
fat mass in % of total body weight and total kg
Baseline, 24 weeks
Fat free mass
fat free mass in % of total body weight and total kg
Baseline, 24 weeks
blood insulin level
Fasting serum insulin (nU/L) was determined by immunoassay (Immunotech Insulin Irma kit, Prague, Czech Republic)
Baseline, 24 weeks
systolic/diastolic Blood presure
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.

Pharmacologic weight loss (Combination Product)
ACTIVE COMPARATORThe 1st group (n=50) receives subcutaneous Semaglutide (GLP-1RA) 1 mg once a 7 day with oral Empagliflozin (SGLT-2i) 25 mg once a day that is a novel combination additionally to standard medical treatment including anti-diabetes, antihypertensive, lipid-lowering, symptomatic therapy.
Surgical weight loss
ACTIVE COMPARATORThe 2nd group (n=50) receives surgical method (laparoscopic MGB). These patients pass through additional pre-operation examination (blood tests and electrocardiography, esophagogastroscopy, ultrasound, and other necessary standard methods).
Very-low-calorie-restriction diet
EXPERIMENTALThe 3rd group (n=50) receives very-low-calorie-restriction diet ('Analimentary-detoxication') including \<100 kcal/day with fat-free vegetables (tomato/cucumber) and salt intake (5-6 g/day), optimum physical activity, and sexual self-restraint. The program goals the next outputs: a) use of own fatty store; b) control endogen intoxication; c) reuse of interim metabolic substrates.
Ramadan fast's weight loss
EXPERIMENTALThe 4th group (n=30) adheres to fasting on Ramadan fast (RF) season. They strictly adhered to two principles of nutrition during RF: 1) "no blood, no smell of fat" which means "don't eat meat and don't eat fatty foods"; 2) the 'Sehri time' (a meal eaten before dawn) included just 1.5-2.0 glass of water and fruits of 80-100 gr (apple, dates, and persimmon). Indeed, the patients followed a diet in which they ate one meal a day - participants have a meal during 'Iftar time' (a meal eaten after sunset).
Interventions
subcutaneous Semaglutide (GLP-1RA) 1 mg once a 7 day with oral Empagliflozin (SGLT-2i) 25 mg once a day
Endovideososcopic techniques with the intraperitoneal using of synthetic/biological materials. MGB is performed to reduce the absorption surface of the gastrointestinal tract by shunting the greater part of the stomach, the duodenum and the initial section of the small intestine, which reduces the absorption of food and leads to a decrease in the production of gastrointestinal hormones.
