How to Lose Weight Fast

will i lose muscle if i do cardio? and how do i lose fat around my stomach and chest?

ok, so i am a 16 year old guy. 5 foot 4. 132 pounds. I lift weights about 6 times a week and do cardio every night (about 3 miles a night of walking/jogging). i also do situps 3 times a week, but i can’t seem to get a six pack no matter how hard i try. So my plan is to do a lot more cardio, but if i do a lot more cardio, will i lose muscle and strength? and is there a way to lose fat without losing strength?

My current diet is

Monday-Friday– Breakfast: banana, cup of milk, and 3 slices of turkey
Lunch: apple, cheese stick, turkey sandwich, 5 slices of turkey, and a carton of milk
Dinner: usually some sort of meat (ie: burgers, steak, chicken, etc), potatoes, and milk

Saturday-Sunday– Breakfast: 2 eggs, two pieces of toast, and a cup of milk
Lunch: Some sort of fruit, turkey sandwich, and cup of milk
Dinner: usually some kind of chicken or steak, and rice, with a cup of milk

So i guess my question is, will i have to lose a lot of muscle and do a lot more cardio in order to get a six pack? and is my current diet good or bad???

Thank you for the answers

if u do not want to lose muscle.. make sure your protein is very high… u are eating enough food…. and always have plenty of protein before and after workouts…

u will not burn muscle the way u are doing it.. u burn carbs first.. then u burn fat .. then if u are not getting enough nutrients.. u burn muscle..

and take some vitamins…

even if u do lose some mass.. u will be more so lean mass afterwards.. and keep lifting heavy.. so your muscles stay dense…
