Any time I have meal planned I have used a combo of my own cooking and then using a meal service to fill in gaps. They're pricey though. I've used Dedicate Healthy Kitchen quite a bit

If anyone lives near Marda Loop and drops in I highly recommend the "Wicked Walnut" protein shake. I've had a lot of protein shakes in my life and JFC that thing is unreal.
I don't really see the need to meal prep 24/7 unless it is doctor ordered or you're competing. It's way too hard to maintain. I'd just change habits.
People would be surprised how much you can lose if you hit the gym 2-3 days a week,
quit drinking alcohol and pop, and stay away from processed foods. I completely quit drinking and weed for 3 months, ate semi clean (no snacks after 9PM), hit the gym 5 days a week and lost about 5% body fat. I firmly believe the liquor was ruining my metabolism.
