I'm going to keep beating this dead horse, but only because it entirely changed my life: I did option "B," minus the carbs (no rice and no potatoes), except instead of crappy chicken and carrots I ate this almost every day:

But not quite as fancy. I stocked up on cheap steak from Costco and Safeway, and grilled up a cheap sirloin every night. For salad, I bought bagged salad because I'm lazy, threw on shredded cheese, and topped with ranch dressing. Literally 3-4 days a week, that was my dinner. The other days were just as delicious and easy: usually an omelet or just eggs with a bunch of cheese, avocado, sausage, and bacon. Lunches were small, usually a chicken sausage and part of an avocado, maybe broccoli or cauliflower (pretty much all carbs were from veggies). On weekends when I had more time I'd cook something up a little different, maybe cauliflower fried rice, or a "keto" pizza.
People who does this will obsess over "macros" and "fat bombs" and ****, but the reason I loved it was because I loved the meals, and they kept me under 1400 calories (probably less; I think I was shooting for 1200), and I FELT FULL. That was really what made it work: I didn't feel full.
I also intermittent fasted, i.e., only ate between 1:30 and 8:30. I'm not sure how much that had to do with it, honestly, but it was super easy for me with what I was eating.
Final reason I loved that "diet": it got me off of bread/pasta/crap. Almost three years later, I don't have bread and pasta cravings, and I used to be the type that would request a second bread basket. A true lifestyle change. I am WAY more proud of the fact I've kept 70 pounds off for three years than the fact I lost 70 pounds in the first place.
So anyway, you do you, MLYLT. But I'm going to continue to suggest that "you" includes eating steak, bacon, and ranch dressing.
