I pay attention to my cravings... They tell me a lot about what is going on with my body.
Common female case in point? About once a month I want steak. Now. Hand over the cow. Easy answer... My iron is low. I can feed the craving just as OMFG, that's good, with spinach. Spinach Gomae, Spinach Caesar Salad, even a great big handful on a roast beef sandwich (cow + spinach ;)) is gonna have about 2,000 fewer calories than a porterhouse beaut of a marbled char grilled steak. It "shouldn't" feel as satisfying to sub a salad for steak (ever. that's just wrong), but if I'm craving iron? It does.
Junk food? Usually means my anxiety is up. Which means my digestive system isn't working well (sympathetic nervous system shuts off digestion) so I'm craving foods that require virtually no digestion whatsoever. Those are great foods for when you're actually sick, or about to be running for your life, but "A broad should be broad... But not that broad!", ahem, a wee bit fattening for everyday living.
Just like the spinach v steak thing? There's an easy solution; go burn off all the stress chemicals in my bloodstream demanding your sympathetic nervous system be running hot, and all of a sudden? Sympathetic shuts off, Parasympathetic nervous system turns back on, & the digestive system comes back online and wants a salad or clean proteins.
If I'm craving more-more-more? Usually means my trace minerals & vitamins are low, but can also mean my protein is low, or carbs are low, or even fats are too low. Regardless, it means I'm out of balance. Packing on thousands of extra calories of "more" whatever the hell I'm eating... Instead of taking a step back and going "Oh. Maybe I should eat more than just _______." Which is a very, very bad habit of mine... Especially when I'm depressed. This past year I can't even tell you how many times I've been living out of the almond butter jar, or the cereal box. ((LOL. Last time I did this I had to fight to get my sugar & vitamins & proteins up. Was living like a rabbit. This time, I've got those three, at least.)) Okay, woman! Go get yourself some durn variety in your diet!!! Dayum. How many times do you want kwashiorkor in your life??? Or osteoporosis? Yeah. That one was fun. There is a supermarket filled with food from around the world right around the corner. Mind the gaps in your diet, chica.
If I'm craving sugar? I'm usually in pain. I have chronic pain, so I tend to ignore it a lot more than I really should. This is one craving I totally rock out with. Brains run on glucose, absolutely needs it / can't survive without it. What can help to modify the craving here, is to manage my pain better. Lower my activity levels (or increase, depending), do my physical therapy stuff, get back on helpful meds if I've fallen off of the self care, ice & heat, etc. Voila. Sugar cravings subside. Until then, though, I carb load. If I don't I'm not only gonna be one hurting puppy, but I'm going to have the attention span of a gnat. Dumb & Dizzy just isn't a good look for me. ;) Just not pretty enough to pull it off.
