Does any of this sound familiar?
Read them slowly. If you find yourself nodding at any of them, this page was written for you.
-
“I have abdominal fat and I cannot shift it.”
Visceral fat cannot be seen or pinched from the outside. It is measured as a VFL index every 15 days, not by eye.
-
“I have lost weight before and put it back on.”
When weight comes off fast, part of what you lose is muscle. Without protecting it, the body returns to where it started.
-
“I have insulin resistance or prediabetes.”
It's not a number to ignore, or to panic over alone. It's measured in your blood panel and followed with clinical judgment.
-
“I use a GLP-1 and I am worried about losing muscle.”
Fat Burner™ works whether or not you use a GLP-1. If you do, training and nutritional control protect the mass the drug cannot tell apart.
If you nodded at any of these, Fat Burner™ was designed for you. Men and women. What follows is the method, with its numbers.
Over 12 weeks, this is what we measure and aim to improve

Personalised training sessions at Spark
60 minutes per session · In person in our dedicated guided strength area in Vitacura.
You do not need a separate gym or trainer, it is included.
Start by measuring, not by committing.
We are not asking you to commit to a 12 week programme blind. We are asking for one assessment: we measure you with the InBody 270, you meet the physiotherapist and you decide with data, not with a promise. If it is not the right path for you, we tell you right there.

The body-recomposition protocol, on four fronts
Fat Burner™ is an in-person 12-week body recomposition program for men and women aged 35 to 60. You train at Spark while our team works simultaneously on your nutrition, habits and metabolic health. It is organized into four fronts: guided strength training, nutrition with clinical supervision, psychological habit support and lab work. Your body composition is measured with an InBody 270 every 15 days, seven times in total, and on day 0 and day 90 a full blood panel is taken.
Blood panel and medication are purchased separately — details under Investment.
Guided training at Spark
In-person 60-minute sessions in our body recomposition area. A physiotherapist guides your strength training with Speediance technology and adjusts the work as you evolve. Your progress is measured with the InBody 270 every 15 days, muscle mass and visceral fat: that data, not the scale, tells whether the program is working.
Nutrition tuned to your energy expenditure
Fat Burner™ works whether or not you use a GLP-1. The nutritionist adjusts your meal plan to your real caloric expenditure every 30 days, and the nutrition physician oversees the clinical front: when medically indicated, the GLP-1 protocol (Semaglutide or Tirzepatide) is added as an extra tool, prescribed and supervised case by case, never on your own.
Improve your habits with psychological support
A psychologist specialized in habit change works with you throughout the program, with a weekly session, working on your relationship with food and your adherence. Why the plan falls apart on a Tuesday, and how it holds without relying on Monday willpower.
This support is focused on habits and adherence: it does not replace psychotherapy and does not promise a psychological discharge in 12 weeks. Discharge from this support is defined by your psychologist at the end of the program and, if she sees you need additional clinical care, she will tell you and point you to it.
Your lab work: the before and after
A blood test panel on day 0 and day 90: fasting glucose and insulin, HbA1c, lipid profile and more metabolic markers. It is the before and after of your metabolic health, interpreted with you by the clinical team, not a PDF nobody explains.
We measure your progress throughout the programme
To confirm that the weight you are losing is mainly fat, not muscle.

-
Body composition
The InBody 270 splits your weight into its three fractions. 7 readings, one every 15 days.
-
Visceral fat
The deep fat — the kind that surrounds your organs — as a VFL index. At every check-in.
-
Segmental muscle mass
Arms, trunk, and legs, each on its own: 5 segments.
-
Blood pressure
Taken at rest as part of the clinical check-in. 7 draws in 12 weeks.
-
Waist / height
How your waist measures against your height. 7 draws.

Weight doesn't tell them apart.
The InBody does.
What the InBody 270 separates, zone by zone:
Visceral fat

It is the fat surrounding the organs inside the abdomen. When it is elevated, it raises metabolic and cardiovascular risk. It cannot be seen or pinched from the outside, and the scale cannot tell it apart.
- InBody 270 every 15 days: visceral fat as a VFL index, plus segmental muscle mass.
Subcutaneous fat

It is the fat under the skin, the one you can pinch with your fingers. It builds up mainly on the abdomen, hips, thighs and arms. The segmental measurement shows where it sits.
- Segmental measurement — arms, trunk, legs — at every biweekly check-in.
Muscle mass

The muscle that sustains your metabolism while fat comes down. If it's lost along with the weight, the number drops and the body doesn't change. That's why we measure it — and train to protect it.
- Guided strength at Spark, with muscle mass tracked on every InBody 270 scan.

Excellent care from the whole team. […] Very professional, technological support with clear explanations. You can see progress thanks to good planning. […] There is support throughout the treatment, both in the session and over WhatsApp.

I work in healthcare, so I always try to inform myself properly before making a decision about my health. […] After 3 months my problem improved and I am free to go back to drinking tea, which I love, and water without fear, and I can travel without having to stop at every service station. This problem really does have a solution here.

The assessment costs CLP 39,000. The programme price is set there.
Your first step to changing your body composition.
In this assessment we establish your starting point, analyse your body composition and help you understand how much fat you need to lose and how much muscle we need to preserve or build.
Our team explains how Fat Burner™ works and sets the training frequency best suited to your goals.
By the end you will have a clear picture of where you are, where we want to take you and which programme we recommend for you.
The blood panel and, when appropriate, medication are prescribed and purchased separately; that expense is reimbursable through Chilean health insurance (Isapre).
The price of the programme depends on the training frequency we recommend and on your level of reimbursement.

Does it work if I'm not on any medication?
Yes. Fat Burner™ combines guided strength training, clinical nutrition and habit psychology to change your body composition, whether or not you use medication. The InBody 270 measures every 15 days how your fat and muscle mass are changing, while the BIOMAP panel analyzes your blood biomarkers at the start and at the end to see how your metabolic health is responding on the inside. We are not only after a change in your body, but also in the indicators that matter for your health.
Do you treat men?
Yes. Fat Burner™ is open to men and women ages 35 to 60. The program follows the same structure for both: guided strength training, clinically supervised nutrition, habit psychology, and InBody 270 measurements every 15 days. What differs is the training plan, which your physiotherapist adapts to your starting point.
How long does it last?
The program lasts 12 weeks. In that time you do guided strength training at Spark, you get measured with the InBody 270 every 15 days, 7 measurements in total, and you have nutrition and habit-psychology follow-up in parallel. On day 0 and day 90 a full blood panel is taken, to see how your key biomarkers and your real long-term health are improving.
Do I have to use medication?
Not necessarily. Fat Burner™ works with or without medication. If your clinical evaluation shows you could benefit from a GLP-1 treatment, it can become part of the program, injectable or oral, always under medical prescription and supervision. Medication is a tool when indicated, not a requirement for results.
Do I have to diet?
More than going on a diet, you need to learn to eat well. If you need to lose a significant amount of fat today, you have probably spent a long time eating more than your body needs or choosing foods that do not help your metabolic health. In Fat Burner™ we teach you what to eat, how much and how often, and also how to recognize the foods worth avoiding. The goal is not a temporary diet, but changing the way you eat for good.
What happens when I finish the 12 weeks?
When you complete the first 12 weeks, we compare your progress across the 7 body-composition measurements and your final BIOMAP panel. With the team of specialists we define the next goal and the plan to keep going until you reach your ideal body composition, improve your metabolic health and learn to maintain the results over time.
Does my Isapre cover it?
The program's nutrition, psychology, and physiotherapy consultations are reimbursable through Isapre and supplemental insurance, depending on your plan, and we give you an itemized receipt with the service code. The blood panel and, when appropriate, medication are purchased separately and are also reimbursable. We confirm the exact detail at your Fat Burner™ Assessment.
What does the InBody measure, and how is it different from a scale?
The scale only tells you how much you weigh. The InBody shows you what that weight is made of: how much fat you have, how much muscle, and where the changes are happening.
That is why we measure you every 15 days. We do not simply want you to lose kilos: we want you to lose fat, protect or gain muscle, and improve your body composition.
Can I start if I am already on a GLP-1 (Ozempic / Mounjaro)?
Yes, with clinical supervision. If you already use a GLP-1 under medical indication, Fat Burner™ integrates with your treatment: strength training and nutrition follow-up help protect your muscle mass. Every case starts with a clinical evaluation: if yours needs a different path, we tell you at the Fat Burner™ Assessment and we don't sell you the program. See the contraindications.
Where are you located?
We're at Av. Presidente Kennedy 5488, Torre Norte, offices 1405, 503, and 1402, Vitacura. Parking is off Kennedy Lateral, next to the Getit minimarket. For more detail on directions and what you'll find at the center, see Fat Burner™ in Vitacura.
How much is it?
The Fat Burner™ Assessment costs CLP 39,000 and includes your InBody 270, baseline measurements and a first consultation with the programme physiotherapist. The price of the 12 week programme is personalised according to the training frequency set by your assessment and your Isapre or complementary insurance cover. In your first session we go through both options and work out your reimbursement and final price with you.
Who shouldn't do Fat Burner™?
The whole program starts with a clinical evaluation: if your case needs a different path, we tell you at the Fat Burner™ Assessment and we don't sell you the program.
Let's start with a session, not a promise.
You leave your Fat Burner™ Assessment with your InBody 270 report in hand, knowing whether this is your path.
Is your pelvic floor also on your mind? It's our other program, with the same clinical team and the same InBody measurement.
