I have been down below the 50lb mark for about a week but I wanted to ensure that it wasn't a fluke. Yes, I have lost 50lbs. Picking up a 50lb weight at the gym is amazing.
There are no tricks to losing weight. It's quite simple, actually. Eat...fewer....calories. In this age of the Internet, there's no reason in the world that the average person shouldn't be able to count calories for most things that they eat. Almost all restaurants have nutrition information on their websites. If they don't, you shouldn't be eating there because the restaurant is most likely ashamed of the junk food status of their menus. It's quite easy for restaurants to do calorie counts -- they are just unwilling to do so.
