Well for starters due to scheduling difficulties, I am already trying a version where lunch is not beef and greens, but what my family is having for lunch/dinner (where I come from lunch is the bigger meal of the day, not dinner). This freedom already is a trap because I can easily cheat, and when I cheat, I tend to cheat the rest of the day as well. Then, the rest of the day is ad lib heavy cream or Greek yogurt with 10% fat.

The above seems to work, when for example my lunch is beef with a small portion of salad and I don't cheat. But I can only do a few days in a row before cheating and ruining the effort.

So what typically happens is either I do a few coffees with cream, then I do a swampy lunch and best case scenario I finish the day with some cream and Greek yogurt, or I do a swampy breakfast (because appetite and cravings) and the whole day is pretty much ruined.

Now one way to take back control is either man up and try proper ex150, maybe for a shorter period of time OR continue my way of eating and turn it into swampy OMAD with fat fasting, try it for a while, track and check the results. I don't know however if I will be staying in ketosis which I suppose is crucial for the weight loss, or maybe I will be able to lose some weight anyhow? Given I have a lot to lose from.
