re: Help me lose 10-15 pounds

Diet is the biggest factor. No liquid calories. Only water and maybe a protein shake.

Start planning meals so you are consistently eating good foods with consistent portions sizes.

You need to be in a deficit to lose weight so figure out what you normally eat during a day and reduce that by 500-1000 calories. Adjust up or down from there over the weeks if you are losing weight or not.

Try to hit a protein goal everyday. Say 100-120g of protein a day. Eat some carbs with your protein. Try to limit the amount of fats you eat because that is the most caloric macronutrient. Balance all of this with your calorie goal.

Working out will build muscle. Find a simple program online that appeals to you. Preferably something with compound movements like squat, bench, deadlift, pull-ups, rows, overhead press. I would recommend Penandpaperstengthapp Grasshopper program.

Stick with it. I would do a minimum of 3 days a week lifting. But you could do up to 5.

Increasing your daily activity will also help. Just move around more. Get on your feet and get stuff done around your house. Get a step tracker and try to hit 8-10k steps a day. This extra movement will help increase your calorie burn and increase your deficit without adding too much stress on your body.
