So, I have a fun wrinkle in my own personal story.
I have gestational diabetes - or at least, my blood sugar numbers are so close to the cutoff as to be something I have to pay attention to.
Nothing like the prospect of protecting your kid's health to kick your motivation into gear.
To be clear, I know that eating to keep your blood sugar in range is NOT the same as eating in a calorie deficit, though there is a lot of overlap in the strategies - load up on protein and fiber, avoid getting TOO hungry or overstuffing yourself, etc.
One thing I'm interested in seeing is how I do mentally eating the same foods for lots of meals - since by necessity I'm probably going to end up eating a lot of the same meals once I've figured out what is 'safe' in terms of my blood sugar. I know that got mentioned way up thread as one of the key strategies folks employ. I've never really done it, since I like experimenting. But I'm going to have to for at least 2.5 months (and hopefully not a day longer, my hips are killing me already).
Anyways, I'll probably end up documenting some of my trajectory and/or food choices in my journal, if you want to follow along.
There's pretty solid research that people eat less when they have less variety. Novel food makes people eat more, so the more repetition you have in your diet, the easier it can be to moderate your intake.
It takes some adjusting to, but I now conceptualize two types of eating:
(1) Food: meals I have on a day-to-day basis for nutrition purposes
(2) Entertainment: things I eat for fun
The food I eat day-to-day is very, very good, very tasty, but it's not exciting because I bulk cook for the week and eat it over and over again. I also make hummus, fresh bread, and hard boiled eggs every week and one of our go-to meals is those 3 plus raw veggies. It's a great cold meal, but we've had it literally hundreds of times, it's not fun, it's food.
Entertainment eating is special occasion stuff and has no rules.
For example, I only cook vegetarian food (and some seafood), but outside of the house I'll eat any meat. I don't keep sugary foods in the house, but have no problem buying pie and ice cream for a movie night.
I don't need my day-to-day food to be consistently fun, I need it to be consistently filling and nutritious. Again, it's REALLY good food, but after the 5th time having the same dish, it doesn't matter how good it is, I'm not craving seconds.
That said, I have an enormous collection of recipes (see page 1 of my journal for 150 of them, a lot of them diabetes-friendly), so I'm big on variety overall, just not day-to-day. I have recipes we'll eat for one week and then not have again for a year.
