Honestly you can get a good, balanced distribution of food by simply following the government food plate guidelines. www.choosemyplate.gov
1/2 a plate of vegetables and fruits
1/4 a plate of whole grains
1/4 a plate of protein
add 1 serving of dairy.
You don't need low fat nor low carb to lose weight. You need healthy fats and complex carbs to properly fuel your body, especially if you're very active.
If you will make your Sparkpage public and share your nutrition and fitness trackers, we can look at your actual activity and provide suggestions based on what you're actually doing. It's hard to make suggestions on what you can do to improve your diet if we don't know what your diet is!
Instructions for how to do this can be found here: www.sparkpeople.com/community/help_answer.
