No, don't give up. Make sure you eat ENOUGH of the allowable foods.. If you're hungry, have more protein/fat (like cheese, meat, eggs) and don't forget your veggies.. A big salad is ok, with lots of lettuce (after all, it is only 1 carb per cup) and other allowable "salad vegetables" according to Atkins site and/or book. And at dinner, 1 cup or so of "other vegetables" plus a bit more salad if you need it.

When I have been out and about some days, I have had not ONE double meat buger (no bun) but TWO of them... the main thing is not to go more than 6 hours w/o food AND to eat when you're hungry, just not to the "overstuffed" point. And drinking the water really really does help for fullness and weight loss.

You can do this! Hang in there
