BODYSIM

Intro

BODYSIM positions itself as "fitness forecasting" rather than fitness tracking. It is described in the source material as an app-based system that builds a digital twin, learns a user’s unique metabolism and physiology, and uses sensor fusion to continuously reveal body composition. The product emphasizes prescriptive workouts and meal plans that are generated from that digital twin, with the stated goal of helping users gain muscle and shed fat.

Key Features

• App-based system that adapts to an individual’s metabolism and physiology.
• Digital twin model used to generate prescriptive workouts and meal plans.
• Sensor fusion approach combining multiple data inputs to reveal body composition over time.
• Precise metabolic tracking with an advanced TDEE calculation that separates Basal Metabolic Rate (BMR) from activity, offering a detailed breakdown of energy expenditure.

Who this is for

• People focused on changing body composition (gaining muscle, losing fat) who want prescriptive guidance rather than passive tracking.
• Users interested in metabolic detail and a breakdown of energy expenditure (BMR vs. activity).
