Description

The 40•30•30 App lets you quickly calculate the percentage of calories in a food from the three macronutrient groups: carbohydrates, protein, and fat.

Several popular diets recommend a 40%-30%-30% ratio of these macronutrients, but this can be a chore to figure out when reading a Nutrition Facts label. Using this app you can quickly enter the grams of carbohydrates, protein, and fat and instantly see the fraction of calories from each of these sources.

Of this app will work as well with any other balance of macronutrients, so you're by no means limited to a 40-30-30 program.

As always, consult your doctor before beginning any new diet.

Math is right

You have to take into account that fat is 9 cals per pop and carbs and protein are 4 cals per pop. Math is right my friends. App is exactly what I was looking for.

Only goes to 99g

Odd and inconvenient that it will only let you calculate up to 99g per category - not even enough for 1 day of food calculation

Reply to nonnie & gttc

I agree GTTC on the calculations but usually just use the Zone's base grams for snacks and multiply by 3 to get my meals. Thought I'd like to try this for individual items if that would help, but pkgd. foods make it hard and why I try to avoid them. I hope this works for my purposes. Glad to see it offered for free though, so thanks Frank. Nonnie, as far as your apps, the same thing was happening to mine. Go to ITunes help menu tab, select Ipod help and run through the troubleshooting diagnostics. Mine ended up being my music videos needed deselected and not resynced. Typically a problem with your other loaded items, ie music, photos, videos, mail. HTH! Good luck everyone with your healthy goals!
