Your metabolism may still be adjusting to your new macronutrient profile. It takes time, often a month for most people it seems, for most of the facets of your metabolism to reach a stable equilibrium at which you no longer feel the wonky effects of adjustment. Likely, you're hungry because you're still a bit insulin insensitive, so low-carbing is leading to low blood sugar as your baseline insulin level is more tailored to that of a high-carber. That low blood sugar is a potent signal for starvation. Give it some time (and maybe a few more carbs for now) until you no longer feel cravings. Once you hit a low body fat %, your leptin secretion will be low enough that you'll need to add some more carbs into your diet to feel totally satiated and craving free. Since you still have 30 lbs. to lose, I'm assuming your craving issue is simply related to adjustment, though.

And yes, your body will crave more food when you approach the crimson tide. Don't deny your cravings in that case, be sure to listen to your body, but be reasonable. Don't go eat a pizza, but feel free to gnosh on a sweet potato.

Hey Oranges, this definitely happened (notice the past tense!) to me. Much better now! Read this:
