Eating only pre-packaged food to lose weight???

You're in a difficult and complex set of circumstances, and I'm not going to challenge you about them. It must take great strength for you to do what you are, and I admire that. It tells me that you can succeed in your quest to be healthier.

If you are hitting your macronutrient targets in MFP (especially enough protein and fats), and adequate calories, that's a great foundation, and more than I see in a lot of food diaries I've looked at here. Kudos!

Like others, I'm concerned that you might be low in micronutrients and other beneficial phytochemicals (such as antioxidants) that many of us get via veggies and fruits (I know you aren't to eat fruits).

You got good suggestions above about steam-in-bag veggies. I'm concerned that those may be on the expensive side, if budget is a challenge. If that's the case, consider the store brands of frozen veg that come in boxes or regular bags. I microwave these in any glass dish with a cover, or just put a plate on top to hold the moisture in.

I hear what you're saying about difficulty of microwaving veggies so that they come out tasty. Frozen ones come out of the microwave a little better for me (following package directions) compared with fresh, but I'd also point out that certain types if frozen veggies come out of the microwave nicer than others. For example, frozen winter squash - if you like it - comes out great. Corn and peas come out decently, too.

I have more trouble getting greens or soft things like broccoli to come out nicely, but one option might be to cook them, mash a bit, and mix in an egg to make a microwave frittata type thing (stir a couple of times mid cooking), which is tasty and a bit of extra protein.

Also, as others have said, consider raw veggies. Some, such as celery or cherry tomatoes or baby carrots, are very easy - just wash and eat. There are a few fresh veggies you can pretty much wash and microwave, too, like sweet potatoes (poke them through with a knife to release steam, and wrap or contain them, of course).

IMO, beyond the micronutrient issue, the only thing you're giving up by going with all packaged foods and so many shakes is learning how to remodel your everyday eating to keep weight off satisfyingly forever. But from what you're saying, this is a temporary set of especially challenging circumstances that you don't expect to be permanent, and your path toward health will allow time to work on that experimentation/learning part later.

I hope I'm not overreaching here, but I'll also add that increasing movement, to the extent you can within physical constraints, will also help with your weight loss and health. I know you're mobility limited. Sometimes people think they need some kind of fancy exercise program or it won't be of help . . . but that's not true. There have been studies showing that fidgety people burn up to a couple hundred more calories daily than non-fidgety ones! Anything you're able to do that is more movement, even stretches, fidgets, head nods, arm waving - they can help a little.

Good luck: Keep on persistently being the strong and resourceful person you are, and I'm sure you'll succeed!
