Dr. Martín Gastón Álvarez · Board-certified 54450
NATURAL FIT Body Contouring® is the only methodology in Spain that integrates three disciplines into a single body remodelling programme: plastic surgery specialising in body contour, personalised nutritional planning, and supervised post-surgical physical training. Developed by Dr. Martín Gastón Álvarez across five countries throughout more than 18 years of clinical practice.
Most clinics operate and say goodbye on the day of discharge. That is the main reason why many body surgery results are lost within the first 12 months. The NATURAL FIT Body Contouring® protocol addresses the three factors that determine whether the result lasts: surgical technique, body composition, and the patient's habits.
Every procedure is performed and signed by Dr. Martín Gastón Álvarez, board-certified plastic surgeon no. 54450 with 18 years of international experience. Vaser technology for liposculpture, micro-cannula fat transfer for natural volume in the buttocks and breasts, and latest-generation CE-certified implants.
Pre-operative plan to optimise healing (3–4 weeks before surgery) and post-operative plan for the following 12 weeks. Tailored to your body composition, type of procedure and goals. Designed and supervised by the NATURAL FIT nutrition team.
Review every 4 weeks with plan adjustments.
12 weeks of supervised physical training at a specialist gym, with progression adapted to the type of surgery. A dedicated trainer is assigned to each patient. Dual clinical objective: accelerate skin retraction and consolidate habits that maintain the result long-term.
Without a post-operative habits protocol, the body tends to accumulate fat in untreated areas, loses muscle tone, and the skin does not adapt to the new contour. Within 12–24 months, many patients see their results partially disappear.
This is not the fault of surgery: it is the absence of a system to ensure maintenance.
We integrate the three disciplines into a single protocol. Surgery marks the starting point. Nutrition preserves the result at a metabolic level. Post-surgical training tones the tissues and consolidates the change. Three disciplines. One team. Results that last.
That is why we are the only clinic in Spain with this integrated approach.
The final decision is always made by the surgeon following an in-person assessment. These are the general indications.
In-person or video consultation of 45–60 minutes directly with Dr. Martín Gastón Álvarez. Clinical assessment, goal definition, personalised proposal and a fixed written quote. No cost and no obligation.
Full blood panel, ECG, anaesthesiologist assessment. Start of the pre-operative nutritional plan to optimise healing. Signing of the informed consent document with all risks fully explained.
Arrival at the clinic 2 hours before surgery. The procedure is performed by Dr. Álvarez in an accredited operating theatre. Post-anaesthetic observation. Discharge on the same day for the majority of procedures, with compression garment and pain management protocol.
Reviews at 24h, 72h, 7 days and 14 days. Manual lymphatic drainage from the first week, included in the price. Compression garment worn 24 hours a day. Most patients resume light activity between days 3 and 7.
Start of supervised post-surgical training at our centres in Eixample and Gràcia. 2–3 sessions per week with a dedicated trainer. Nutritional plan adjusted every 4 weeks. Surgeon reviews at weeks 4, 8 and 12.
Definitive result visible between the fourth and sixth month. Final review with clinical photography at one year. The extracted fat cells do not regenerate: the habits consolidated during the 12 weeks are what maintains the result in the long term.
Each of these procedures is carried out within the comprehensive surgery + nutrition + post-surgical training framework.

The NATURAL FIT Body Contouring® protocol is designed as a whole. Surgery without follow-up delivers a surgically correct result, but its long-term maintenance depends entirely on the patient. We therefore always recommend the complete programme. Exceptionally, we do assess patients who already have their own nutritionist and trainer and prefer to coordinate them with our team.
It depends on the procedure. For lower-impact interventions (focal liposculpture, arms, jawline): 2–3 days for office work, one week if your job is physically demanding. For major procedures (3D liposculpture, abdominoplasty, BBL): 7–10 days for office work, 3–4 weeks for intense sport or physical labour. We provide a medical certificate if required.
Yes. We treat patients from all over Spain and internationally. The initial assessment can be done by video call. After surgery, the patient must stay in Barcelona for the first 7–10 days for critical post-operative reviews. The remaining nutritional follow-up can be coordinated remotely; in-person training is replaced by a supervised remote plan with fortnightly check-ins.
The plan is adapted to each patient. Those with no prior experience start with mobility work and walking; patients with a fitness background progressively resume strength training. The key is that every phase is supervised by the assigned trainer.
The fat cells that were removed do not regenerate in the treated area. If significant weight is gained, the remaining cells (in untreated areas and, to a lesser extent, in treated ones) can enlarge and alter the contour achieved. That is why the integral programme includes 12 weeks of habit consolidation. Weight fluctuations of 2–4 kg do not affect the result.
Yes. NATURAL FIT Body Contouring® is the only clinic in Spain specialising in integrated surgery with nutrition and post-surgical training under a single team. The protocol was developed by Dr. Martín Gastón Álvarez following 18 years of international practice across five countries.
