Just listen to your body. uVida gives it a voice.

The uVida Food metabolic analysis can determine your personal basal metabolic rate, i.e. the exact calorie requirement at rest and how much carbohydrates, fat and protein the body burns proportionally. Whether you're looking to lose weight or improve performance, you'll receive a personalized assessment via the app and can get customized nutrition and training plans. With the right combination of exercise units and a diet tailored to the individual physical situation, the set wellness goals can be achieved so efficiently. Just like the pros.
