How in the actual fuck are you eating a meal like lunch that contains 237 calories? I'll use the term "meal" loosely... The proper term is a light snack.
1200cal a day on average?
If I were going to give you good advice I'd tell you to forget about taking steroids... It'll be a fruitless endeavor for you.
Now that I've got that out of my system... What are your goals?
Best way to organize this is to first find your TDEE, look it up. Use a few calculators, figure up an average and go from there.
Once you have a TDEE established, decide if you want to lose weight or gain it. Let's say your TDEE is 3000cal, if you want to gain weight then start eating 3500-4000cal... Lose weight, start eating around 2500cal.
Macros - you can do this any number of ways, easiest for you will probably be to get about 1-1.5 grams of protein per pound of bodyweight. I'd shoot for at least 200 grams a day at your bodyweight. Then you have fats and carbs, you can split them evenly to get the rest of your calorie needs or you can get more of one and less of the other depending on what kind of foods you like.
The math works out like this: 4 Cal per gram of carb, 4 Cal per gram of protein and 9 Cal per gram of fat... Bonus - 7 cal per gram of alcohol.
