If you aren't, try weighing every thing you eat in a day (ok, you can skip weighing lettuce.
). When you look up foods use the USDA measurements in grams. For example: "apple usda" then you can really get a very close estimate of your calories in a day. You can use a tablespoon for peanut butter and other oils, but otherwise, weigh every thing for a week and get a much more precise measurement of calories. That's the only thing I can think of. Also, I've learned as I've gotten older that I can't stay on the plan for 6.5 days and then have a big meal or big treat once a week. IF I do, I undo all that weeks calorie deficit.
That's all I can think of.
