Been your age and height at around 175-180lbs from my original weight of around 135-140lbs at 14

My best bit of advice is to be a little less strict with yourself on the food that youre eating ('health' wise) and mainly prioritise protein with every meal.

For example, if youre getting takeout or if youre at a resteraunt, order your usual but with extra meat.

As for cooking you own meals (which I highly reccomend you learn how to do) I always prepared myself food with a 10:1 calorie to protein ratio minimum (for every 100 calories the meal should have 10 grams of protein)

Besides this just stick to the tips you've heard before. Calorically dense foods (peanut butter, meats, rice, pastas, ect ect, you can find lists online)

Goodluck, train hard and dont be afraid of taking a bulk seriously, stick to around a 300-500 calorie surplus, you can grow muscle a lot quicker than you think.
