I have used it- but only to prove a point to prove for an argument - not because I had any remote interest in it. I have a good friend that owns a CF gym and he constantly touts the CF koolaid ad nauseum. I debunk his rhetoric any chance I get as he has such a narrow a viewpoint most of the time. As he kept insisting it would 'improve my triathlon performance' I did the RP diet two different times - once about a year ago using the manual templates and once using the new app - for 6 weeks in duration each separate time. I did not lose any weight or change BF composition with that diet, but my diet is already very clean and pretty strict to start with. My own opinion is that the app could lead to some weight loss
'IF' a person's current diet and calorie intake will be reduced enough to produce weight loss. However, if it is just 'shifting macros', with approximately the same caloric intake (as in my case) it may not produce any results. I had virtually 95% compliance and the biggest change besides limiting foods available to eat was the shift in the food groups to higher protein (no surprise). My carbs were limited to about 120g per day - I was not in ketosis, but it was enough reduction where I felt like shit and it impacted my workout performance.
My observations were that the app is way easier to use than the older manual templates, but the foods available in the app are extremely limited and the nutrition combinations that 'support' the workouts are only for strength - not endurance activities as you mentioned (ie. the app precedes a 3 hour run with 35g of protein meal-that's not going to happen for me without barfing it up). Also, the workouts can't last longer than 3 hours in duration. It's free to download and try for 2 weeks - so it's easy to try out and play around with to see what the meal combinations are like without paying for the the monthly fee. It's probably a feasible option if one is off season or doing only a few hours a week of light training for a sprint distance, but to try and pair it up with any serious half or full ironman training regiment is going to be difficult to achieve in my humble opinion.
Everything you say here is correct. I am one of about 20 contractors for RP. The RP app doesn't currently suit endurance athletes well, by itself. Your performance will tank as soon as the app algorithm cuts carbs.
Hence, I wrote and designed the RP Endurance Macro Calculator. It calculates daily nutrition recommendations based on much more endurance-specific inputs, far outside what the app is currently capable of handling, including kJ/kcal data from a power meter, and can be used alongside the app or be used as a standalone nutrition guide. Just thought I'd clarify this since endurance folks might stumble into this thread in the future, as I did.
Full disclosure: I got booted from this site a few months ago because I found this thread via google, having embarrassingly little/no idea what slowtwitch.com was, and I posted all sorts of related product info (rookie fail). Per Dan Empfield's recommendation via email after I blundered through a "Why can't I access my account?" email inquiry to him, I've since attempted to contribute much more on this site with the intent of discussion on the site itself, rather than just linking out to related info and products. If you're unsure of my intentions, please review my post history.
This site is awesome and I hope to remain a part of it for reasons far outside marketing, and also hope to not be banned from engaging in discussion on the one thread (this thread) on the site that concerns my primary line of work!
FYI: by FAR, the biggest pitfall with the RP app's recommendations for endurance athletes are the intra-workout carbohydrate amounts. If you ARE using the app without the mentioned calculator above, please at least follow the following table for hourly carb needs for optimal performance. The app will have amounts that are trivial by comparison.
