Enteroprotein Modified Fast ( EMF )

Enteroprotein Modified Fast ( EMF ) : Clinical Safety and Efficacy. A Six Months Pilot RCT

The purposes of the esperience is:

1. to verify the safety of protein sparing modified fast(PSMF) by enteral route ( EMF )performed in cycles of ten days/months for six months
2. to compare EMF with oral PSMF clinically ( appetite control, fat freemass mantainance, polmonary function tests and metabolic pattern)
3. to verify the weight mantainance after 6 months from the treatment suspension

Rationale A) primary endpoint

1. to verify the safety of protein sparing modified fast by enteral route ( EMF )in cycles of ten days/months repeated for six months,
2. To compare EMF with oral PSMF clinically ( appetite control, polmonary function tests and metabolic pattern) and on metabolic parameters (hypertension, glucose intolerance, dyslipidaemia) maintaining body composition (particularly fat free mass and muscular strength) in 15 patients with disease-causing obesity not responding to medical treatment and/or cognitive/behavioural therapy, who are candidates for invasive treatment such as the gastric balloon or surgery but do not intend to undergo them compared with 15 undergoing the same regimen without the naso-gastric tube. To verify the effects of treatment with regard to the enteral-hormonal structure during the acute phase (selected sub-group) and while undergoing treatment.

B) Secondary endpoints:

1. To verify the percentage of patients who maintain the weight reached 6 months after stopping treatment with the naso-gastric tube associated with a high-calorie normal-protein diet.
2. Verify clinical safety of EN in these patients.
