I am badly craving a taco and was going to make street taco's with corn tortillas. I know one will be enough but has anyone tried this?

I would think eat the meat filling and chase it with a lightly cooked soft corn tortilla - just to have the taste. The tortilla might fill you up otherwise.

I do. Can't eat much but I'll have it.

You can, though you have to check how much you can eat overall and if it fits in to the meal and your plan for the day. My fast food of choice, on the rare times I had such, was an order of Chipotle soft tacos with corn tortillas - one to have there and two for future meals. While I was losing and well restricted I mostly just at the filling and that was enough. The main use I made of corn tortillas at that time was to crisp up a thin tortilla and use it as a small pizza crust - that was about the right size.

The main thing that I would be a bit concerned about is that you are craving tacos - what about them are you craving? If its the tortilla, that may be a warning sign that you are being triggered to overeating foods that aren't doing you much good. If you can be satisfied by just eating the filling, thats a good sign that you are being driven by something fundamentally nutritious, which isn't a bad thing. If you just gotta have the tortilla, that's not so good as they are mostly (not entirely) empty calories, which can be a big negative for your long term weight control efforts.

For me, the tortillas are incidental - I can take them or leave them; I just use them as a convenient carrier for other foods, but am not bothered if they aren't there.

From the beginning, I have treated my weight loss as a journey I will continue - not as a short-term "diet." Once all foods were allowed, I ate what I wanted. If I want a corn tortilla and it fits into my 3.5 ounce meal, I have it. I tried for a month going low carb - under 35g - and I didn't lose weight any faster. I don't eat processed starches everyday, but if I want a few crackers, I have them. I have learned that if I don't eat what I am wanting, even in a small quantity, I will overdo it on other things I really don't want. I used to be of the mindset that if I have one bite, I will have gone down the rabbit hole never to return. Thankfully my mind has clicked. I think it is because I know that this is how it will be from now on. I do measure all my food and eat 90% protein, but also allow myself to have a few bites of other food groups, even those that are not protein heavy.

I've tried the carb balance Mission tortillas when doing shrimp tacos. I usually can't finish the tortilla because I'm stuffed after I get the shrimp and broccoli/carrot slaw in.
