I'm focused on size again (after having dropped a great deal of fat) and less concerned about carb depletion right now, but still mindful. So on low carb days I have a bowl of Quinoa pasta with a small chicken breast or some black beans and a hand-full of diced green olives (rinsed) at lunch.
The Quinoa provides a substantially appropriate quantity of complex carbs as well as good protein, and digests more slowly than higher glycemic carb sources such as some fruits like oranges, bananas, pineapple, tomatoes, and more slowly than traditional pastas - even the other whole grain pastas.
Then I stay away from carbs after 5 p.m. and turn to lean red meat (only eat top-round/london broil for red meat source) trimmed to 0% fat, and cottage cheese - a superior form of casein which is very slow digesting and still substantive enough to satisfy.
The other trick is to eat mindfully and slowly.
Remember, the body does not signal that the stomach is 'full' until fifteen to twenty minutes afterwards, so the more slowly you consume late-in-the-day proteins when you're carb depleting, the less your body will signal a craving.
Eating slower digesting carbs like black beans, oats, sweet potatoes/yams at mid-day/early evening meals (meal three and four on a six to seven meal plan) and eating slowly will actually calm down your carb craving.
The other thing to remember is that if you're less than three months into a strict change in diet where 'white foods' like refined flower and sugar have been cut from your diet, your body is still going through a kind of detoxification. Sugar and white flower are cruel task-masters in the system, and getting off of them can take your body some time before it no longer craves.
Having recently exited the holiday season, it's very likely that you indulged (deservedly) in sugary, cake-y treats. It's like filling your car with one tank of low-grade fuel and then filling it with high-test when it's only half-gone. It takes time for all the lesser fuel to work through the system, and a little bit longer for the neuro-receptors neuro-transmitters to stop firing in response thereto.
Be patient, be diligent and be reasonable with yourself and cravings for the bad shit will cease.
And remember always - lots and lots and lots of water.
