Focused on flat stomach & larger butt

So you haven't lost any weight? Something is off in your calculations. Are you weighing your food and using measuring cups?

You won't build muscle while on a deficit, so the most you can hope for is to reveal the muscle that is already there. You pretty much have to pick either build muscles, or lose weight. Lifting while you are losing is great for preserving what lean body mass you already have.

strong lifts or starting strength

deadlift and squats. start learning the form and work your way up to as heavy as you can get.

also sounds like you need to work more on body recomposition than weight loss. eat at your maintenance and follow a heavy lifting program like strong lifts or starting strength

Are you:
1) Using a digital scale to weigh everything?
2) Logging literally everything you eat?

Looking through your diary, most days you are well under 1000 calories logged with very little protein. Considering your weight hasn't reduced, I'm guessing you are not consistently logging everything you eat.

Your goals require you to accomplish two things: reduce fat mass and increase muscle mass. Since you are already at a healthy weight range for your height, focus on improving body composition by increasing muscle mass with progressive weight training and consuming a high-protein diet (a minimum of 100% of your lean mass in lbs). If your body fat percentage is reasonably low, you can eat at a small (200-250) calorie surplus - after establishing what your actual maintenance calories are - for a few months to maximize the amount of muscle gained. You'll likely gain 1 lb of fat for 1 lb of muscle so, after several months, you'll cut back calories down to maintenance and then drop to a small deficit to reduce fat mass but keep as much of the muscle you gained.
