Muscle building Protien

You'll only build muscle if you eat at a surplus so you will inevitably gain both muscle and some fat in the process but as long as you don't over do it, you can keep the fat gain to a minimum.

Chicken
fish
whey protein (although you don't need this)
eggs

are cheap protein sources and are filling. Keep in mind this isn't a fast process and you need to stay dedicated to it.

not sure what you mean by tone up but if its how you think you mean you will not "tone up" it's a long process which you have stated but you won't do that while on a deficit. Just focus on weight loss and retaining as much of your current muscle as possible. Start lifting weights and get yourself a routine. Then when you hit 180, you can begin the real building process.

I'm just telling you this because I got down to my goal weight of 160 and wasn't how I expected to look since I lacked muscle and now I'm just building myself up. Good luck.

Extra protein won't make you stronger or buff you up. That being said if you currently aren't getting enough protein then sure eating more would help with muscle building.

If you eat more protein then your muscles actually need it just gets converted to fat to be used for angry later. There are many different sources that say you need different amounts of protein as low as .6 grams of protein per kg of body weight. On the opposite side of things I've seen people say you need up to 1.6grams per pound of body weight for muscle building (which is likely way to high). The number that seem to make the most sense to me was 1 gram per pound of LEAN body weight. I would recommend doing research and see what number makes the most sense for you. iffym.com is a good website for finding your macros (carbs, protein, fat intake) macros are important to watch while strength training.

@William4MVP was right about needing surplus to build muscle. That being said if you are new to strength training some people do see increases in strength while in a deficit. If your goal is still weight loss keep with the deficit and start lifting to retain muscle then once you hit your weight goal then start working on building muscle. I would also recommend when this time comes start out by eating at maintenance then move to a calorie surplus.

The most important thing if you want to gain muscle/retain muscle is your lifting program. You can make your own routine but if you're a beginner its probably a good idea to find a pre made one. You can find lots online a good place to start is bodybuilding.com they have tons of workouts (if this post catches more attention you'll probably find more recommendations I can pretty much guarantee stronglift 5x5 will come up lol). If you have a good routine that works all your muscle groups great stick with it!

I'm not sure what you mean by toning up though? if you just want to look more muscular just keep lifting and with low body fat you'll look "toned." When you lift one thing that will effect how your muscles grow is the reps/weight you use. Speaking very generally, low reps (5ish) at close to max weight is for strength building, medium reps (10ish) and a little under max weight is for muscle size, and high reps (15+) with low weight will train for muscle endurance.

You really don't need any kind of supplements pre workout is mostly just caffeine, if you have trouble getting in your daily protein you could look into a protein shake but really protein from food or a powder is no different.

Goodluck with your goals. The important thing to remember is you won't see tons of muslcr/strength gain until you're out of a deficit but it's still great to lift to maintain muscld.
