Weight loss that goes beyond the scale.
Personalized nutrition, training, and lifestyle coaching designed to help you lose weight, improve metabolic health, and build habits that last — with or without GLP-1 medications.
If you’ve tried diets, exercise programs, or medications only to find yourself starting over, the problem may not be a lack of effort.
Weight regulation is influenced by nutrition, muscle mass, insulin sensitivity, sleep, stress, hormones, medications, genetics, and your environment.
At Precision Metabolic, we bring those pieces together into one individualized strategy.
No crash diets. No generic plans. No shame. Just clear guidance, measurable goals, and a plan built around your life.
Success isn’t defined by one number on the scale.
Our clients have achieved meaningful improvements including:

Weight Loss Program
Taking the medication is only part of the process.
GLP-1 medications can be powerful tools for weight loss, but reduced appetite can also make it harder to consistently meet your nutritional needs.
The medication works. What you build around it decides what lasts.
Adequate protein, resistance training, and a maintenance plan built early help protect your progress — on medication and after. Medication decisions always stay with your prescriber.
While you’re taking a GLP-1.
We provide guidance on food, nutrition, and lifestyle while you’re on these medications. We help you navigate:
The medication can support weight loss. We help you build the lifestyle that supports the result.
Medication prescribing, dosing, discontinuation, and medical adverse-effect management should be handled by an appropriately licensed prescribing clinician.
Coming off a GLP-1 is a transition — not the end of the journey.
As medication is reduced or discontinued under your prescriber’s guidance, hunger may return, cravings may increase, portions can grow, and maintaining weight loss can become more difficult. We help you prepare before those changes become setbacks.
You worked hard to lose the weight. Now let’s build the lifestyle that helps you keep it off.
Turn your health goals into everyday action.
Practical support with nutrition, movement, sleep, and sustainable routines — so your goals and your doctor’s recommendations become habits you can keep.

Build muscle. Get stronger. Improve your conditioning.
Training that fits your life — not a life that has to revolve around training. Personalized strength, muscle-building, and cardio coaching built around your goals, schedule, and fitness level.
It is not 0 or 100. It is the right amount, done consistently.
You do not need hours in the gym to make meaningful progress. We focus on the few changes that deliver the biggest return.
That may mean 45–60 minutes — or 15–30 minutes, a walk, or a few key exercises. We start with what fits your life and progress from there.
Six reasons progress stops.
{{ y.t }}
{{ y.d }}
Small changes. High-return habits. Clear progression.
We focus first on the highest-return changes you can repeat. Start with the minimum effective dose, build consistency, then progress.

Build muscle with a system.
Cardio with a purpose.
A 20-minute workout you consistently complete can be more valuable than a 90-minute plan you rarely follow.
On busy days, the plan can shrink without disappearing: a short lift, a few key sets, a walk, or brief cardio. Consistency first; build from there.
From starting point to progression.

Stronger, fitter, more capable.
A complete training plan.
Stop working out at random. Start training with a plan.
Stronger. Fitter. More capable — without making the gym your entire life. We identify the highest-impact changes, fit them into your life, and progress at a pace you can sustain.
Fitness coaching is educational and supportive and does not replace individualized medical evaluation or physical therapy when clinically indicated.
Look deeper. Act earlier. A clearer picture of your heart health.
Heart disease is the leading cause of death in the U.S. and worldwide. Get a customized plan to lower your risk — alongside your medical care.
Go beyond the standard cholesterol panel.
We help you understand advanced lipid markers, insulin resistance, diabetes risk, inflammation, and other drivers of cardiovascular disease — so you and your clinician can identify risk earlier and act before disease develops.
We help make the difference.
Meet one-on-one. We take the time to understand your health, build a personalized action plan, and give you clear, actionable next steps.

Harout is a Boston-based Physician Associate at Massachusetts General Hospital and a Certified Strength & Conditioning Specialist.
With training in functional and preventive medicine and a background in emergency medicine, he focuses on early detection: reading your labs and performance data to spot risks before they become problems. As a nutrition and certified strength and conditioning specialist, he turns those findings into practical lifestyle changes that improve how you feel and perform.
He founded Precision Metabolic to help people connect health knowledge with everyday action — through clear education, personalized planning, and ongoing support. The practice combines medical knowledge with practical expertise in nutrition, exercise physiology, strength training, behavior change, and metabolic health.
The goal is to help you understand your priorities, build confidence in your choices, and create habits you can maintain.
Better health requires more than telling someone to “eat less and exercise more.”
Clients need to understand what is happening in their body, know which changes matter most, and have a realistic plan for putting those changes into practice.
Precision Metabolic bridges the gap between medical care and everyday life.
Precision Metabolic is an independent coaching practice. Coaching does not provide medical care, diagnosis, or treatment, and is not affiliated with or endorsed by Massachusetts General Hospital or Mass General Brigham.
