Just gonna say, carbs aren’t going to kill you.

The best thing you can do for your body is to eat a balanced diet, and understand how nutrients fuel you. Eating hyper specific foods exclusively is not some sacrifice for being healthy. There is a always something you miss nutritionally when you do things like this, and the downsides of starving certain nutrients far exceeds whatever benefits you’re looking for.

I recommend having a portion of veggies, protein, and carbs with every meal. If it’s weight you’re worried about, the best dietary adjustment you can do is to not eat between meal times. If it’s some attempt at hyper protein-based body builder diet, then maybe take a step back and consider how eating healthy is actually going to reinforce the enjoyment you can get out of exercise.
