Why serious weight loss starts with tracking your heart.

Why your weight loss journey needs real medical insight

A weight loss journey tends to start with hope and a plan. You decide to change how you eat, move and take care of your body. You want to feel better, boost your energy and improve your long-term health. Progress feels exciting, but there is always one question in the background. Is your body coping well with the change?

Your heart, circulation and metabolism respond to weight loss in real time, and having a way to monitor these changes can make the difference between a smooth transformation and a dangerous setback. This is where medical-grade technology becomes invaluable.

The Eko CORE 500 digital stethoscope introduces a level of personal health monitoring that was once limited to clinical settings. Its advanced sensors, precision audio, ECG readings and optional AI support allow you to understand what is happening inside your body as you lose weight. For anyone serious about transforming their life, this tool brings clarity, safety and confidence.

Eko CORE 500™ Digital Stethoscope

The pinnacle of digital stethoscope technology, combining TrueSound™ audio with 3-lead ECG and a full-color display.

Why the heart matters in a weight loss journey

Weight control and heart function are tightly connected. When body weight starts dropping, your cardiovascular system responds. Blood pressure may fall, circulation may improve and your heart rate may shift as your metabolism adapts. These are positive changes, but they must be tracked safely because rapid adjustments can be stressful for the heart, especially if you have been inactive or have underlying risks.

By using a device that captures real-time heart sounds and ECG data, you gain a window into how your heart is handling your training sessions, meal plans and recovery. Instead of guessing whether your heart is beating too fast during a workout or whether a strange sensation is harmless, the CORE 500 gives you accurate information backed by medical technology.

It works by amplifying body sounds up to 40 times and filtering out environmental noise with its TrueSound system. You hear crisp, clear recordings that reveal details many traditional stethoscopes cannot detect. For anyone losing weight at home, this means you finally have a realistic way to spot changes early and stay on track.

The Eko CORE 500: A modern health tool for everyday use

The CORE 500 is a digital stethoscope designed to replace the traditional model used by healthcare professionals. Although it is a clinical instrument, its features make it powerful for individuals who want deeper insight into their physical progress. You get a device with unmatched audio clarity, a full-colour display that shows ECG waves and a built-in system that captures heart activity with medical accuracy.

For those on a weight loss journey, this means you no longer rely on a basic fitness tracker that measures heart rate alone. Instead, you gain access to the richer, more detailed diagnostics that doctors use when evaluating cardiac performance. This helps you exercise more confidently, monitor recovery and stay aware of any warning signs.

The device is built with durability in mind. It is splash resistant, scratch resistant and built from high-quality materials such as anodised aluminium and silicone. It runs up to 60 hours on a single charge in regular use and comes with a 1-year warranty and 30-day risk-free trial for peace of mind.

Tracking your transformation with precision

Clearer sound for clearer decisions

One of the biggest advantages of the CORE 500 is its sound quality. Weight loss changes your breathing patterns and heart rhythm during exercise. Listening to those sounds with professional clarity helps you understand how your body is coping.

TrueSound technology cancels background noise and brings quiet details to the foreground. That means you can hear your heartbeat accurately at home, outdoors or in a gym environment.

ECG data at your fingertips

A built-in 3-lead ECG separates this device from anything used by the average fitness enthusiast. Instead of depending solely on optical sensors that estimate heart rate, the CORE 500 gives real electrical readings.

You see your heart activity displayed on the full-colour LCD. This allows you to spot irregular patterns that may need attention, especially if you are pushing your limits during workouts.

AI-supported insights for earlier detection

With an Eko+ subscription, you unlock AI tools that help detect murmurs and signs of atrial fibrillation. These two conditions often go unnoticed in people who are starting weight-loss programmes, especially after years of inactivity. Early detection protects you from unnecessary risk and ensures that your fitness routine supports your health instead of harming it.

Recording and sharing your progress

The ability to record, save and share body sounds or ECG snapshots means you can send accurate data to your doctor, coach or nutritionist. Instead of describing symptoms, you can provide actual recordings. This supports faster decisions and reduces the chance of misinterpretation during your journey.

Safety and motivation through measurable data

Health monitoring is not only about detecting danger. Data can motivate. When you hear your breathing improve, when your heart rate stabilises during exercise or when your cardiovascular recovery time shortens, you gain evidence that your effort is working. Many people give up because they feel progress is slow or invisible. The CORE 500 provides the reassurance that change is happening.

It also supports safer training. If your heart rhythm looks irregular or your heart rate takes too long to recover, you can slow down or adjust your approach. This prevents overexertion, which is one of the most common causes of injury among those starting a weight loss regime.

The device’s portability means you can use it before a workout, during rest periods or after finishing a session. Over time, you build a clear picture of how your body adapts.

Understanding the full package: What you receive

The CORE 500 is sold with several important accessories and tools that support your weight loss journey. You receive the digital stethoscope, extra ear tips, a USB-C charging cord, ten alcohol wipes and a Quick Start guide. You also gain a 14-day free trial of the Eko+ membership, which unlocks advanced AI, unlimited recording, patient profiles and PDF reporting.

Many buyers are eligible for reimbursement through employers or health plans, and it may qualify as a tax write-off for self-employed clinicians. The provided reimbursement receipt includes order details, HSA or FSA instructions and justification language for CME.

The device itself meets strict global standards. It is FDA cleared, UKCA marked, ISO 13485 certified, MDSAP certified, HIPAA compliant and GDPR compliant.

How the CORE 500 strengthens a weight loss journey

A weight loss journey requires consistency and awareness. You are building a new relationship with your body, and monitoring your progress keeps you grounded. The CORE 500 supports this process in several ways.

It keeps you informed about your cardiovascular health. It helps you adjust your training intensity safely. It gives you early warnings if your body is under stress. It brings clarity to your progress and allows you to share accurate information with healthcare professionals. It also gives you measurable proof of improvement, which strengthens your motivation and keeps you committed.

Many people rely on guesswork throughout their weight loss journey. The CORE 500 replaces guesswork with knowledge. When you understand what is happening inside your body, you stay in control.

Building a health-focussed weight loss routine

Adding the CORE 500 to your weightloss routine is simple. Before each workout, check your resting heart rhythm and breathing. During training sessions, monitor how your heart responds to increased demand. After exercise, check how fast your heart returns to its resting pattern. Over time, these measurements build a clear picture of cardiovascular improvement.

If something feels off, you can review your recordings, replay the sounds and look at your ECG waves. This allows you to communicate precisely with your doctor rather than relying on vague descriptions.

The device works with both iOS and Android devices (iOS 16+ and Android 12+). Even if you choose not to continue with the Eko+ membership, you retain access to essential features including real-time visualisation and wireless listening.

Your weight loss journey deserves the best tools

Weight loss is more than changing your appearance. It is about longevity, strength and confidence. As you transform your lifestyle, investing in accurate health monitoring ensures that every decision supports your overall wellbeing.

The Eko CORE 500 digital stethoscope brings modern medical insight into your daily routine. Its precision, sound clarity, ECG capabilities and optional AI analysis give you the safest and most informed path toward your goals.

Every journey is easier when you understand your progress. With the CORE 500, you take charge of your health in a meaningful, measurable way. It is a tool that strengthens your motivation and keeps you moving forward with confidence.
