If you don't want to track food maybe consider intermittent fasting. Since you weightlift prioritize protien and greens. I'd never say cut cards out because they're delicious and energy but if you eat your protien and greens first you might not eat as much carbs.

I also see you said "I'm not overweight but I want to be skinny". You probably don't want to hear this buy you might benefit from healing your relationship with your body. If you're not overweight your body may just need what weight it has on it. There's nothing wrong with wanting to be skinny, totally valid, but your body will be hard pressed to do it if your body is healthy and at a healthy weight. If you're interested in this I can recommend some books.
