Okay so I've lived on my own since I turned 16 and at first I cooked everything, but after a while I got out of the habit and started to just snack rather than eat meals. I rarely have meals. I'm still reaching an acceptable amount of calories but it's all just fatty foods. I can't go for long without becoming fatigued. If I'm going to start working out again I need the energy. What kind of meals do I need to start eating in order to give my body the energy it needs?
