The Pie Graphs in the latest app upgrade

I'm not going to swear that I'm right, but those percentages look pretty close to the numbers the FDA and Health Canada used to recommend decades ago. I wouldn't be surprised if they have not been updated.
The sad thing is that high carbohydrate diets are more associated with obesity, metabolic syndrome, and CV disease than traditional diets.[ North American pre-1960s, Japanese, Mediterranean ,etc.]
I usually advise my clients to lower the carb amounts to [conservative] something more like the 40/30/30 to start with and down the road maybe something like a 20/60/20[non-conservative].
Good luck sir.

I would ask you to research the two longest living populations in the world, that's China and Japan (they have the most amount of people over the age of 100) and see what kind of data they are pulling out of those countries. I cannot name the report myself since I own the DVD but I can tell you that after people retired, they lived longer due to calorie restriction (about 10% every decade). Again, I don't recommend this to you but to inform you that there are ways to good health and long life. Again, your goals are different so please take advantage of any free but experienced care.

My parents are both in their 70s and they do fine with line and ballroom dancing (at the senior's club) and going for walks twice a day along with house maintenance and daily activity. Good luck to you!

Okay, I will weigh in as a professional in the fitness and nutrition field. The Actual Recommendations come form the Institute of Medicine Board of Nutrition and are adapted by the various boards of various countries (Like the FDA). The actual recommendation are in ranges, not exact percentages, and are as follows:

Carbohydrates--45 to 65% of total calorie intake
Protein--10 to 35% of total calorie intake
Fat--20 to 35% of total calorie intake
Saturated Fat--Less then 7% of total calorie intake (This is included in the total fat number above.)
Added Sugars--Less then 25% of total calorie intake (This is included in the total carbohydrate number above.)

Protein also has recommendations based on grams per kilogram of body weight. The standard recommendation is 0.8 grams of protein per kilogram of body weight. I typically use that recommendation to determine the % of protein based on the calorie needs of my clients and then adjust the percentages of carbs and fat based on their other goals. If I'm working with a person who has different protein requirements (such as someone with kidney issues who have to have less then 0.8 grams per kilogram, or someone who is doing a lot of exercise who have to have more then 0.8 grams per kilogram), then I adjust it first and then rearrange the percentages based on the individual.

Unfortunately, places like the FDA, MFP, and any other organization that is giving recommendations to large populations, they can't get specific to the individual needs of one person because it may be completely unhealthy for another person (IE: recommending a high protein diet for someone with kidney problems), so they tend to pick an arbitrary percentage somewhere in the middle of the range or the average % of the population they are advising to make it easier for them to figure. Unfortunately, for sites like this though, there isn't nutritional counseling that goes along with the recommendations to let everyone know that they should be in a range and not to stress if they aren't 100% perfectly on that one percentage used by the tool. Your percentages are in the ranges, so I wouldn't worry about adjusting them, honestly, unless you are having medical issues or are not seeing results from your program.
