I haven't had McDonalds since about 2009. That was just due to it being the only option and I was hungry after going to the gym and having to drive with my wife to drop her mother off out of town. Before that the last time I had it was 1999.
I haven't had KFC since 1999. I used to love their works burgers I thing it was with the pineapple.
Those two were easy to eliminate. Burger King and Wendy's (keep the sponsors happy) have been a bit harder. Found since I move to a big city and burgers from various franchises (Burger Fuel etc) are easy to get that I've developed a love of burgers. Become more regular compared to living in a small town where you'd need to drive to another town to get it.
My biggest weakness is still lollies.
After a health issue a few years ago I cleaned up my diet, eliminated all processed food. I was pretty much living off.
Breakfast - porridge
Lunch - Sandwich or chicken salad
Dinner - egg white omelette and vegetables
I was pretty much eating separately from my family. The same thing everyday isn't ideal as it is imbalanced and hard to stick to. But the rigidness helps with the first part getting the weight down.
I can ease off a bit now.
My lunch is still similar. Mainly as I like the structure of meal prepping. Sunday I prep my lunch for Monday, Tuesday. Tuesday night I prep for Wednesday, Thursday. Thursday night I prep for Friday.
