It should be balanced as far as macronutrient ratios go (you can change the ratios in one of the dropdowns), but the proportions of macros you want may change based on your goals. The default 50/25/25 split should be good if you're trying to build muscle, and with weight loss, you'll probably want fewer carbs and a higher fat/protein proportion. I'll add some presets at some point to make it more straightforward.

Aside from macronutrients though, I would either take a good multivitamin or make sure you're getting the rest of your vitamins/minerals from lean vegetables.
