Thank you for the story, costahobo! There are people who can eat a lot and stay skinny, there are those who eat very little and stay fat. I wonder what's in the McD's in Costa Rica. Is it the corn oil GMO? Corn-fed CAFO beef? What about HFCS? Soybean oil? Is the wheat dwarf hybrid or the older wheat? 10 years is quick. Did Costa Ricans suddenly stop exercising? Nobody has it all figured out yet so we need all the data we can get.
5'0" female, 43 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Current weight: skinny-fat 106 lbs. Resetting with the 21-day challenge.
MY PRIMAL: I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I aim for 80-90 g carb/day and advocate a two-month strict adjustment for newbies. But everybody is different and other need to tweak Primal to their own needs.
