Hi. I'm a newbie here but this topic struck me, so here's an odd story re meat cravings.
Years ago I tried a Ginseng & Longon formula, on which I felt great stability and vigor. I got more done, colors were more radiant, etc. The weirdest thing, however, was an intense craving for red meat. Really intense. I'd not been vegetarian but suddenly I'd wake up thinking a juicy rare steak would be wonderful. If I was watching a National Geographic show on wildlife, it would cross my mind "that would be good grilled." It was an almost comical urge ... not unlike the cartoon Madagascar (I think it was that one) in which the lion thinks in thought bubbles that turn into steaks.
So after a month on that, and I might've lost 4 lbs. or so of overweight (not due to fewer calories than usual or fewer carbs), day 3 rolls around. (I'm female.) On day 3, I get on the scale and I'm 9-10 lbs. above the day before, and lethargy set in around that day and forward, to the extent that later that month I stopped using the formula on the theory that it had done something too powerful, or whatever. Lots of blocked/stuck feeling (not necessarily constipation). The weight did not disappear.
My history at length, for what it's worth, just in case anybody wonders what constitution was the setting for the above:
I've had a lifelong weight problem, was only able to lose weight as a teen (from 160 lbs. around age 11) by cutting back drastically on calories and carbs and staying on a diet that other people would vanish on. (Lesser cutbacks and exercise did nothing over long periods.) At this time my cholesterol went high (on a very low fat diet). With this and plenty of aerobic exercise I was able to maintain my weight into my 20s, and raising calories to 1200-1300 a day (still not a lot of carbs) I slowly gained weight, and that accelerated in my 30s. Midway in there I started taking thyroid hormone. I raised my calories to 1400-1500 a day and have been able to maintain with lesser exercise at a higher weight. These days, in my 40s, I'm 5'3" and about 180 lbs. I average around 100 carbs a day and still the same calorie range.
My birth mother was a type II diabetic as were many in her family, and died in her 50s from it. I've never in my adult life had the carb intake that a typical American diet has, and have had one doc suggest that is likely the reason I'm not diabetic now - I tend to concur. A couple other anomalies are that when I had a glucose tolerance test in the 1990s, I had a weird pattern that I could only find in one test book associated with pituitary source: Upon drinking the sweet drink at the start of the test, my blood sugar went up to the normal expected high, and then declined to the normal expected baseline. Except the decline was not over several hours as is supposed to happen, but in the first 15-30 minutes (straight up, straight down), indicating blood sugar being removed at a very rapid rate... indicating action of insulin. (I was on a low carb diet at the time surrounding the test though.) The other oddity is that I test borderline low in estrogen and have for years (no androgenic features though). I've had fat collect around my thighs, waist is relatively slim, quite a bit of accumulation of fat or edema on the back that seems to change from morning to night.
I'm currently undergoing fertility acupuncture treatments and the practitioner has found a low, weak pulse, tongue coat indicating damp heat (with red tip), and the attempt at raising kidney yang set off a cascade of faint flashes and heat and dryness, so the practitioner is now working on the theory of lots of resistant, damp heat with kidney yin vacuity (as well as kidney yang deficiency but needing to address the other two issues first or more greatly to avoid problems).
I sleep well and don't wake up in the middle of the night, hate getting up early in the morning, feel best in the evening, don't get really hungry, love a cool, damp climate but not cold, am pale/ruddy. Sometimes (lifelong) if I'm really fatigued a rare steak or medium-rare hamburger gives me instant energy that nothing else does.
I've had two unusual periods of effortless weight loss that did not seem to relate at all to calorie or carb intake, just that the weight loss switch turned on and I felt great: Once for a couple months while taking phentermine (which is speedy and I believe works with the epinephrine system etc.) The other after having dental work in which they had to give me massive amounts of numbing injections (I clear that fast) that have epinephrine in the shots. Once back home my adrenals essentially crashed for a few days and I could barely get off the couch as if just wiped out of power, my facial skin shed as if I'd had a strong acid peel (presumably peripheral blood flow was that impacted), and after thew few days of wipe-out I started losing about a pound a day or every other, until I'd lost about 15 lbs. and felt great with lots of energy. That stayed off two or three months then crept back on up to my prior weight before the loss.
OK, that's all I can think of!
