    Out of curiosity, and with a recent thread in the back of my mind, what symptoms would a person with undiagnosed metabolic syndrome have?

    Heh, I almost asked that same thing, since I've only had the fasting glucose test. (Well, and cholesterol, of course.)

    (But due to that other thread I'm pretty committed to the idea that I am NOT insulin resistant.)

    (Still can't get the image of Oprah out of my mind, though.)

    I'm pretty positive I've never been insulin resistant.

    One of my takeaways is not to assume your primary doctor knows this stuff, if you have signs of metabolic dysfunction see an endocrinologist.

    Sometimes the specialist relies on what they were taught 15 years ago, which may or may not be evidence based (ie, many endocrinologists believe that a suppressed TSH will cause osteoporosis).

    You hear all the time "even if the scale isn't moving maybe you're lost inches." OK, so assuming the person in question is in a deficit (and therefore of course can't build muscle) someone explain this logically. How does one get physically smaller but not lose weight? Second, can the opposite occur? As in, can one GAIN inches (again, in a deficit) but have the scale drop? Go.

    I lost 15 lbs (which was significant for me) before I lost a single centimeter anywhere.

    Question, when we ladies get extra hungry around our cycle, is our TDEE actually higher for a few days?

    I have read that it is but I don't remember how much higher. Probably not enough to offset chocolate covered pretzels. :laugh:

    I would love to know this. Can I mark it down as a "lightly active" day instead of "sedentary" and stop beating myself up... I might do that anyway to be honest and just consider that time as maintenance, for my sanity at least.

    Or perhaps we could have a Cycle activity with a set amount of calories that we have burned ;)

    I can weigh myself every day and see as much as a 3 pound difference within one week. Is that really due to gains/losses? Water weight? Is it really possible to gain two pounds in one day only going about 600 calories over my lose 1 pound a week deficit calories? The scale is a mystery!

    Use one of the weight trend web-sites that show you a trend-line and your daily weight-ins in relation to the trendline. A couple I use are www.trendweight.com and www.weightgrapher.com. It is effortless with a connected scale; more work by hand. The second one allows you to import a CSV file too.

    Assuming scale accuracy (which is an assumption by itself), yes, our weight fluctuates. Digestive + elimination process, glycogen stores, muscle tissue repairs, fluid and electrolyte balance, hormonal issues...

    Oh yeah that was another sign I had for many years, high triglycerides.

    Well if neither of you ever had any signs of insulin resistance, that obviously proves you had it. The exception proves the rule!

    Well I would look up symptoms of hypothyroidism, insulin resistance, sleep apnea, pcos...

    Some concerning signs to me would be apple shape/ high waist circumference, fatigue after meals, hypoglycemia, irregular periods, and darkened skin around neck and armpits

    Gotcha. You know who I'm thinking about in regards to asking the question.

    I do have hypothyroidism, but those other issues don't pan out. Well, the period one didn't when I still had them.

    I am counting down! Memorial Day will be my official year, then I can say I'm menopausal.

    Too bad your anniversary doesn't fall on independence day!

    Dear Oracle,

    My question is this: if my RMR is 1800 kcal/day, how does that break down? Perhaps in terms of brain, heart, viscera, muscles at rest, and fat cells?

    For bonus points, what powers these parts? Brain runs on glucose, right? Supposedly we burn fat at night, so does that mean all other organs directly metabolize FFA?

    Live these questions. There must be answers available to your second set of questions, but I really don't know. I would think more than just the brain uses glucose.

    I was just too lazy to google. Here we go:
    http://en.wikipedia.org/wiki/Basal_metabolic_rate
    • Liver 27%
    • Brain 19%
    • Skeletal Muscle 18%
    • Kidneys 10%
    • Heart 7%
    • Other Organs 19%

    For the second part:
    http://www.ncbi.nlm.nih.gov/books/NBK22436/

    Brain: It consumes about 120 g daily, which corresponds to an energy input of about 420 kcal (1760 kJ), accounting for some 60% of the utilization of glucose by the whole body in the resting state.

    OK, if the brain uses 60% of the glucose, that means we use a total of 200g/d or 700 kcal.

    So, if my RMR is 1800 kcal, that's 1100 kcal from fat at 9 kcal/g or 122g/d of fat.

    Muscle: The metabolic pattern of resting muscle is quite different. In resting muscle, fatty acids are the major fuel, meeting 85% of the energy needs.

    85% is very close to what we have left after the brain eats a bunch of glucose. We're left with 280 kcal of glucose and 1100 kcal of fat. 1100/1380 = 80% of energy from fat.

    How does the liver meet its own energy needs? α-Ketoacids derived from the degradation of amino acids are the liver's own fuel.

    Wow. I guess this means we need about 486 kcal/d of protein to run the liver. Or about 120g. That can't be right!

    I don't think the minutiae matter and I have to ignore it all and just concentrate on CICO to be successful

    Whilst it's interesting theoretically, considering it all for practical application in my own life simply lead to inertia or worse yo-yoing

    At the heart of weight loss, and for the vast majority, it simply doesn't matter

    Can someone explain how stress can make you gain and lose weight?

    I can stay in my calories and sodium, staying at home, no contact with Real People, and just living my average life with average stress. No nightmares or being woken up out of a sound sleep for no reason. I gain .5#, gain .5#, gain .25#. Yesterday, I ate over calories and sodium, went outside and dealt with Real People and the MIL, had stress over not getting my work done in 90 minutes and dealing with stupid drivers, got woken up out of sound sleep at 4a, had 2 nightmares of being murdered in my sleep - lost .5#.

    I can understand stress either aiding gaining or losing weight, but how does it do both at the same time? I tried being calm and attempting meditation and I find I just gain weight (I didn't overeat). When I get to the point where I tell myself Eff This and just chow down, I lose.

    Well this is interesting, but without the biology background I think it is tricky to figure out based on a few numbers. The body is also creating these substances.

    Okay so I gained about an inch in my late 20s, early 30s, I'm wondering if weight gain could have caused actual height gain, and will I shrink with weight loss? I also wonder if my feet will reshape and I'll fit shoes better.

    My hands and feet both got smaller with weight loss. I expected my fingers to get smaller, but my feet going down a size shocked me.

    I guess if the soles of your feet or, less likely, the top of your head gained weight/fat you'd have gained some height.

    As far as I can tell, I'm still the same height but people say I look taller. Maybe it's just being thinner or maybe I don't slouch as much.
