Are you a true endomorph, or just someone looking for an easy out. Your above post screams attitudinal problems.
Take some time, rethink your position. You have to make a conscious choice to change and be fully willing to invest the time(planning, prepping), energy(training), money(gym membership), and dedication(dedication).
Oh, and since you are an "endomorph" you will be likely able to gain muscle while losing fat, so get the gym membership and start lifting, please.
You also don't need to be no a keto diet, try moving more and eating less.
