How Does GoBe U Track Calorie Intake?

GoBe automatically tracks your calorie intake using HEALBE FLOW™ Technology, without the need to log food manually or count calories yourself.

Unlike apps that require manual food entries, GoBe measures the actual energy absorbed by your body, providing a more objective view of your intake.

How It Works

GoBe uses a bioimpedance sensor to detect changes in interstitial fluid dynamics associated with glucose and nutrient absorption throughout the day.

Here is how the process works:

• after eating, your body digests food and breaks nutrients down into glucose and other compounds that enter the bloodstream;
• as cells absorb glucose, fluid shifts occur between and within cells;
• GoBe detects these fluid changes using bioelectrical impedance measurements;
• the FLOW™ algorithm analyzes these signals to estimate how many calories your body has actually absorbed.

GoBe tracks calories at the absorption stage, not simply at the moment you eat.

Why Timing Matters

Digestion is a gradual and multi-stage process. Depending on the type of food and individual physiology, nutrient absorption may continue for many hours.

Approximate digestion timeline:

• 1–2 hours — chewing and initial processing;
• 3–4 hours — digestion by digestive juices and enzymes;
• 4–8 hours — continued digestion;
• 5–9+ hours — nutrients enter the bloodstream.

Some stages overlap. For example:

• simple carbohydrates such as sugar or sweets may begin absorbing within 15–30 minutes;
• complex meals with fats and proteins may continue digesting and absorbing for 9–10 hours or longer.

This is why calorie intake may sometimes appear long after a meal.

Why Calorie Data May Change During the Day

Calorie values in the app are not considered final immediately after they appear.

The algorithm requires additional time to analyze physiological signals, refine nutrient absorption timing, and distribute the data more accurately across the timeline.

GoBe uses an additional analysis window of up to 12 hours. Because of this, calorie values for previous hours may slightly change during the day as new data becomes available.

Daily data is considered fully finalized only after noon of the following day. This is a normal part of how the algorithm improves overall accuracy.

What Affects Nutrient Absorption

Many factors can influence digestion speed and nutrient absorption.

Sleep

Poor sleep affects hunger and satiety hormones. Increased ghrelin and reduced leptin levels may influence appetite, portion sizes, and nutrient absorption.

Stress

Stress increases cortisol levels, which may:

• slow digestion;
• alter gastrointestinal motility;
• worsen fat and nutrient absorption;
• affect food transit speed through the intestines.

Physical Activity

Moderate activity such as walking, swimming, yoga, or light jogging usually supports healthy digestion.

However, chronic overtraining may increase cortisol levels and negatively affect digestion similarly to stress.

Chewing Food

Thorough chewing helps improve nutrient absorption. Eating too quickly or “on the go” may worsen digestion and affect absorption timing.

Hydration

Insufficient fluid intake may slow digestion and nutrient absorption processes.

Food Composition

Different foods digest at different speeds. For example:

• fiber is poorly digested;
• fats and proteins usually require longer digestion and absorption times.

Medications and Supplements

Some medications and supplements may affect digestion and nutrient absorption.

Hormonal Fluctuations

Hormonal changes during the menstrual cycle may also affect digestion speed and absorption patterns.

What About Fasting or Dieting?

GoBe also tracks energy obtained from the body’s internal reserves, such as stored fat.

This becomes especially noticeable during:

• fasting;
• intense physical activity;
• calorie restriction or dieting;
• long breaks between meals.

As a result, GoBe may show energy intake even when no food was consumed. This reflects the body using internal energy reserves rather than food intake.

Why This Matters

Unlike traditional calorie counting methods, GoBe focuses on absorbed energy rather than estimated food calories.

This allows the device to account for individual metabolism, digestion, lifestyle, and physiological factors, providing a more personalized understanding of your energy balance and metabolic activity.
