Mostly meat diet
 

i just started lifting and im 6'2 260lbs. i just want to lose weight and gain muscle. im in school and i work so im never home to make meals. i want to know if i bake like 2lbs of skinless chicken breast a day to get 200 grams of protein what else should i eat. and is this a good idea?

Read the stickies in the nutrition forum. They should clear this up for you.

You'll actually need a little more protein than that at your weight. 1 gram per lb of body weight is the usual recommendation.

Maintenance calories are 14-16 calories/day per lb of body weight.

Spread your calories over 5-6 meals. In addition to protein you'll need carbs (some starchy and some fibrous) and good fats. You'll have to figure out what works for you. Some of us are only able to get lean by limiting carbs.

A lot of meat would only be good for cutting, if your goal is to build muscle you'll need to supply your body with the proper building blocks which are all three macro nutrients.

As far as building muscle & burning fat, it's difficult, but possible. Building muscle you have to have a surplus in your calories, it puts your body at an anabolic state, cutting fat requires you to burn more calories than you consume which would put your body at a catabolic state. It's difficult to gain muscle in the deficit due to you're taking a lot of the building blocks away.

If you do burn fat while building muscle, it's a much slower progress.

I like to add veggies, complex carbs (usually brown rice or oatmeal) and a source of protein to my intake. A typical dinner for me is...

8 oz of grilled chicken
50g of brown rice
spinach
