Under recommended calories, but not hungry for more?

Starvation mode is a myth.

Eating 200 fewer calories daily is an additional 0.4 pounds burned in one week (assuming 1270 granted you a 500 deficit). That isn't extreme; it's fine. Listen to your body and don't be scared to eat more should you want, but that is sustainable.

When I first started here I was frustrated and hungry and not losing weight at around 1600 cal per day.
Now that I've adjusted to eating a lot healthier and have added more less-calorie-dense foods into my diet, I also have been finding myself stuffed and happy at around 1100-1300 calories some days, which I have found surprising. My new goal is set to 1350 and I've been losing weight consistently (though still slowly). I think you're probably fine as long as you get close to 1200 and you hit your recommended macros/nutrients etc.

For me, personally, it don't eat up to or down to a number. On days I'm more hungry, I eat more. When less hungry, I eat less. If I crave extra carbs before that time of the month, Hello, lasagna. If I want more turkey and fewer veggies, great. If I want no meat and mostly fruit, yay that.

I don't know most of the acronyms people use and I don't do math. That's me.

If sticking to a number works for you, great! It isn't necessary to lose weight, though.

I have been eating the same portions and calories, working out the same amount but I yoyo 3-4 pounds every day?! Any ideas anyone?

Weight fluctuates. Check it in the morning after a week.

If it's still as you've described, you're underestimating how much you're eating and/or overestimating how much you're burned. No other explanation. Make sure you've updated your goal section for accuracy of the target numbers to which you're trying to adhere.

Thanks Ortho!
