I'm using MyFitnessPal to help me watch what I eat. It's a great little app, and it's already helped me shift a few lbs in a week just by thinking a bit more about what I'm eating.

It automatically goes for 50% fat, 30% carbs, 20% protein but I was wondering what a fun runner like me should aim for?

I average 20-25 miles a week (when I haven't got a crappy cold etc), and have started doing boxing/boxercise once or twice a week too.

Any thoughts out there?

As someone who does a significant amount of exercise, you might be better reversing the fat and carbohydrate percentages. The protein percentage is higher than necessary unless you're aiming for a calorie deficit with a view to losing weight, in which case a protein intake as high as 25-30% of total calories can help you feel less hungry and has a (very small) muscle-sparing effect.

I'm probably about 60-65% carbs, 20-25 % fat and 10-15% protein. Usually at the lower end for protein. That's currently fuelling a somewhat fluffy physique to around ninety minutes a day of largely easy to moderate exercise, with a 30-ish parkrun and a fair bit of elevation.

My muscles aren't noticeably wasting away with that, nor is my middle. When i blogged about my daily diet once, a notable Fetchie (and fish fan) described it "stodgy" and she may a bit right.

Got something to say?
