I've not read all the replies above, so I apologize if there's any redundancy in this...The answer is "it depends"- here's a few things to think through
1. It depends if you're 'well-trained' or brand new to training.
I would say I am muscular in general, but have never done any weight training until recently.
Stronger in legs, abs, cardio.
This is your saving grace and why for
you, the answer is yes, you can build muscle while being in a calorie deficit. Well-trained folks will have a much harder time putting on any meaningful muscle while in a calorie deficit- though possible to
keep what they have while losing body fat.
We recently did an entire nutrition program in the Mtntough app reviewing this. If you send me a message, I will get you access to the nutrition section to learn more.
2. "Just lift and eat protein..." is not the answer. In fact, neglecting the other nutrients (carbs and fat) will ensure you
don't achieve your full potential. Consuming other macronutrients 'spare' the protein to ensure it does repair the muscle and you have ample energy for the muscle to recover. The ‘dreaded’ insulin spike is what triggers muscle break down to stop and begin the rebuilding process.
3. Strength or 'building muscle' is relative to body weight. Many folks (not all) think because they're moving less weight on a bar, they're 'getting weaker'. That's not true. Here's an example:
Someone who weights 250lbs can bench 225lbs. They lose 100lbs and now weight 150lbs. Their bench drops to 185lbs.
They're not weaker. In fact, they're MUCH strong benching 123% of their body weight vs 90% of their body weight in the previous example.
So, if you DO notice you can't lift 'as much', don't let that be your barometer for success. Instead, use a gauge of noticing whether or not you have enough gas in the tank to get through a whole workout with thorough intention and good energy (vs gassing out mid-way through).
Hey guys, appreciate all the replys. My goal isn't losing weight to be honest, more of improving cardio first, and a bit of muscle gain 2nd. Then when i feel like my cardio is good, maintain that and make muscle gains my main goal.
I try to eat healthy, and due to my schedule, it just makes it hard to eat healthy and get enough calories every day.
I've lost about 12 pounds over the last 3 months. 5'10", about 177 right now.
Diet lately while working is usually an Atkins shake and some bran for breakfast. Then usually 2 chicken fajitas and some yogurt for dinner.
This might be where you're shooting yourself in the foot, however. It's going to be extremely difficult to build muscle if your training is aimed at cardio. Not only are you likely not devoting enough of your training time to strength, but you're doing strengths greatest antagonist in the time you do have.
I admit I'm making alot of assumptions here about how much time you devote to each discipline, but generally speaking, it's going to be tough gaining muscle with a heavy emphasis on improving your cardio.
