About NutriTiming® on the iPhone / iTouch

NutriTiming® the only program that assesses ‘within-day energy balance’ (i.e., energy balance in real time rather than at the end of the day or at the end of 24-hours.)  Staying in good within-day energy balance by removing large peaks in energy surpluses and energy deficits has been found to be a critical factor in weight loss, improvement in body composition, helping athletes achieve optimal performance, and better sense of well-being.  The NutriTiming® program, which runs on the iPhone/iTouch and/or web, can help users stay in the desirable energy-balance range during the day.  

Users of the iPhone/iTouch can purchase a copy of NutriTiming® through the iTunes APP store for a 1-time fee of $9.99.  All subsequent program updates are provided to iPhone/iTouch users of the program free of charge. This is a fully functional stand-alone program that will provide users with an easy iPhone interface for entering foods and activity to determine within-day energy balance and energy substrate (i.e., carbohydrate, protein, and fat) intake, both of which are provided in numerical and graphical form.  This information enables the user to adjust eating and exercise habits in a way that sustains a better within-day energy balance. 

 

Resting energy expenditure is predicted using a well-established and validated equation (Harris-Benedict) that incorporates the user’s height, weight, gender, and age to determine caloric expenditure at rest.  The user can override this information if they have had resting or basal energy expenditure measured through indirect or direct calorimetry, or a related method. 

 

The energy expended in activity is based on a 1 to 7 relative intensity scale (1=rest; 7=exhaustive activity).  Both time of activity and intensity of activity can be selected, and the caloric cost of activity is displayed so that users can optionally adjust intensity to match the energy expenditure derived from a worn device (heart-rate monitor, accelerometer, etc.)  Only activities with intensities above normal daily activities need to be entered, as all other times are predicted.  This is a timesaving feature.  In addition, activities can be labeled to more easily remember what was done during the day. 

 

NutriTiming® on the Web has the same basic functionality as NutriTiming® on the iPhone/iTouch, and costs $7.00 per month ($17 for the 1st month for individuals who have not purchased the iPhone/iTouch APP) or $80.00 per year (plus $10.00 for individuals who have not purchased the iPhone/iTouch App).

 

In addition to the within-day energy balance functionality on the iPhone/iTouch, NutriTiming® on the Web also provides the ability to: automatically assess (no addition user input) vitamin and mineral intake for each assessed day; store an infinite number of analysis days (the iPhone/iTouch App stores the most recent 7 days of analysis); interact with a nutrition/dietetic expert (expert fee not included) for dietary consultation; and print out energy balance and vitamin-mineral analysis results.

NutriTiming® on the web and NutriTiming® on the iPhone/iTouch are both stand-alone programs that can interact with each other.  You can run NutriTiming® on the web without the iPhone/iTouch, and you can run NutriTiming® on the iPhone without the web.  Using them together has some added benefits to the user, including a synch capability to assure that your most recent entries are on both platforms…If you do a partial analysis on the iPhone/iTouch, you can complete the entries on the web and vice versa.

Sample of Efficient User Interface and Output

Figure 1. Within-day energy balance graph; turning the iPhone/iTouch to the horizontal position will always display this graph, regardless of where you are in the NutriTiming® program.

 

 

Figure 2.  The hourly display screen makes it easy for you to see precisely where you should have eaten more or where you ate too much.  Pressing any hour let's you view/edit your food consumption and activities for that hour.  You can use this as a planning tool to make certain your exercise plan and diet are perfectly matched so you get the most out of your exercise.

 

 

 

Figure 3.  The Energy Substrate Distribution Pie Chart (i.e., the % contribution of carbohydrate, protein, and fat to total calories) is always available by turning the iPhone/iTouch to the horizontal position.

 

 

Figure 4.  It's easy to update your personal values (eg, weight) when they change so your predictive values are always accurate.
