It is not a generic protocol. It is a proprietary methodology developed over 18 years of surgical training in the USA, Brazil, Mexico, Argentina and Spain — and the only one that integrates surgery, nutrition and training as a single process.
Localised fat in the abdomen, flanks, waist, arms or legs does not disappear with diet or exercise — it is structural fat. NATURAL FIT Body Contouring® removes it with surgical precision while preserving the natural anatomical silhouette of each patient: the goal is not to sculpt a new body, but to reveal the one you already have.
The result does not depend on the scalpel alone. That is why every patient works before and after surgery with a clinical nutritionist and a trainer specialised in post-surgical recovery — the only protocol of its kind in Spain.

80% of patients who fail to maintain their results after body surgery never had a real post-operative follow-up. At NATURAL FIT Body Contouring®, the post-surgical protocol is mandatory: a clinical nutritionist who adapts nutrition to each phase of recovery, and a specialist personal trainer who works on toning from the very first week.
It is not an extra service. It is part of the process from day one and included in every procedure.
Meet the teamResidencies and specialisations in the USA, Brazil, Mexico, Argentina and Spain. Each country contributes a distinct surgical school — a combination impossible to replicate with local training alone.
The result looks natural because it starts from your real silhouette, not an external aesthetic mould. Vaser, PAL Microaire, Renuvion and Argón Plasma deliver a precision that conventional surgery cannot match.

Not as an add-on: they are part of the protocol from day one. The nutritionist prepares the body before surgery; the trainer begins work in the first week of recovery.
