Hi Louise,
Taking Omega Rx together with Sea Health Plus could be the answer to eliminating your husband's reflux problems with fish oil. This specific combinaltion eleminates any GI difficulties with fish oil. He should not go below the number of blocks daily that the Body Fat Calculator recommends (
http://www.zonediet.com/tools/body-...lculator). Lean Body Mass (LBM) refers to the weight of everything in the body excepr for body fat. Changes in LBM over time reflect changes in the amount of muscle you have. The significant change in you block recommendation since August could be due to retained fluid from your previous way of eating skewing your initial LBM and body fat calculator results. Also, it may be closer to only a 1 block difference if you were to calculate it by hand using the tables found in Zone books (there's rounding involved with the calculator). Dr. Sears recommends taking a baseline calculator result after you've been eating Zone meals for 2 weeks. By that point you will have lost any retained fluid caused by your previous diet. Your increased weight on the scale even though your measurements remain the same, would usually be due to gains in LBM, though 10kg (over 20 pounds) would be a very large gain in muslce mass. My guess is that 2 years ago you were probably retaining fluid, which would have infalted your actual measurements, and you may also may have had slightly less LBM By now you probably have lost the fluid with the Zone, but possibly have more body fat than you used to, and probably also a little more LBM. Keeping in mind that a pound of LBM takes up less space than a pound of body fat, all these things put together could account for what you have described.
