Need stats, age/gender/height/weight/bodyfat estimate, of course your diet/training and most importantly bodytype. But there's some general basics to answer your questions.
1) Regarding food:
1a) No chocolate, sweets and most that bs. If you want sugar, eat fruits.
1b) Red meat usually has a lot of fat, more often than not a 2:1 fat/protein ratio (no carbs but it depends on the food), if you work out your body is going to use the protein for building muscle and use the fat as an energy source. If not, you're not going to build muscle, the fat is still going to be an energy source (as it always is) but chances are some of the fat will be stored in your body.
1c) No potatoes, nachos, or at least not more often than once a week. No cola either. I don't see a problem with fried eggs at all though, they are basic nutrition for most bodybuilders/fitness models. 50:50 fat/protein ratio with high biological value.
1d) Whole grain bread/rye bread > white bread due to the lower glycaemic index = raises your sugar level less and is beeing slower processed by your body which means most of it will be burned while also nurturing your body for a longer period of time.
How much fat should you eat? Well people generally say 1:1,2-1,5 kg weight to fat ratio for the typical diet, but it also depends. If you really wanna cut, you'd be better off eating fat than carbs as carbs are the first source your body takes energy from when burning calories and after that the body starts burning fat, but you would also have to eat more fat than the previously mentioned 1,2-1,5g per kg as you'd diminish the kcal taken by carbs. Basically chances are more likely that you'll slim down from eating fat and dieting than eating carbs and dieting, unless you don't work out enough and/or eat like a roidjunkie powerlifter, aka in excess.
But like I said, you can't expect good tips personally for you if you don't mention any of your stats.
Thanks for the help! I'm 8 days into my diet right now. I haven't took any cans or bottles of soda since the year started. I've been drinking water, orange juice and milk. What energy drinks would you recommend? Red Bull is packed with sugar, not sure about Lucozade but I'd imagine the same.
I'll stick with eggs cause they're good to build muscle, but I'll probably just take boiled and scrambled. Can anyone give me an example of a good daily recipe? Every diet plan I'm finding is telling me to eat low fat, high carb stuff and the like. But I'm new to this stuff so I'm not sure what exactly to get, you know?
By the way, I'm 18. About 6'0 tall, and I'd say probably about 160lbs. I have no muscle definition, I'm just working on my abdomen right now, then I'll work on my arms and chest. I'm gonna start running in the morning and such.
