From deficit for weight loss into surplus for muscle and strength gains
I (M30) feel a bit "chubby" in the sense that I don´t have a defined body. I am around 178lbs/81kg and 5"9/175cm.
To lose some weight I have put myself into a calorie deficit of approximately 750-1000 kcals. I am planning on doing this for 3 or 4 weeks. My TDEE is roughly 2100-2300 kcals. While in kcal deficit I am making sure to take in 2-2.5 grams of protein per kg of body weight and cutting carbs quite a lot, usually the carb intake is 50-75 grams total.
The goal is to reach around 169lbs/77kg with a focus on weight loss. Once achieved I want to start going to the gym to build muscle up while keeping my body fat percentage at a relatively low number.
I am struggling with what my "new" diet would look like to be going to the gym for muscle (and strength) growth. Are there any ideas here? What's a good surplus to reach some growth while limiting body fat increase? Is there any beginner friendly progressive overload plan that actually is realistic? The gym feels very "scary" as I have only gone a couple of times (months) when I was in my teens and forgot most of the stuff the PT showed/taught me.
All advice or comments are very much appreciated!
