NutriTiming by Calorie & Pulse

Built by IAM Apps

NutriTiming™ is the only iPhone and iPod touch program providing a revolutionary way to track your “Within Day Energy Balance”—a system used by Olympic, professional and other elite athletes from all over the world. Developed by top sports nutritionist, Dr. Dan Benardot, the within-day energy balance strategy is now available to the general public. Through NutriTiming™, you can now achieve REAL TIME, individualized calorie and activity guidance that will enhance your weight loss, nutrition, body composition, and performance goals.

Energy balance has traditionally been assessed over periods of 24 hours, but this 24-hour assessment fails to consider the fluctuations in energy balance that occur on an hourly basis, which can influence your body’s response to calories. Measuring within-day energy balance in real time resolves this problem. By staying within the prescribed energy balance boundaries (+ or – 400 calories during the day), you can target fat loss and spare muscle mass, improve athletic performance, avoid low blood sugar that can make you feel less alert and too hungry, and improve your attention span and sense of well-being.

NutriTiming™ helps you match on an hourly basis your actual need for calories with your present rate of calorie usage. The right amount at the right time means a leaner you with NutriTiming™.

Reports & Graphs

Know when and how much to eat in real time by viewing a simple graph to determine whether your energy balance is too high or to low (higher than + 400 or lower than -400).

Use simple graphs to review end-of-day energy balance. To lower your body fat level, you should end the day with an energy deficit of between -100 to -400 calories. To increase muscle mass, you should do resistance activity and end the day with an energy surplus of between + 100 to + 400 calories.

Turn the device sideways to review REAL TIME within-day energy balance graphs. Make certain you spend the day in the ‘green zone’.
