I have to limit myself to 1 Atkins product a day or else I stall, they are great in a pinch but not to replace 3/4 of the day's meals IMO. I think its all the sugar alcohols and crazy Atkins math that throws it off.
I would say figure out some food stuffs you can make ahead of time and have on hand like the Atkins bars, but real food instead. I also only have 1 meal a day and my day goes as follows
Morning- coffee w/sugar free syrup
Lunch- Atkins bar or shake
Afternoon- pre-packaged salted peanuts or 2oz of cheese
Dinner- varies, but typically a decent sized portion of meat and a veggie
Maybe have hard boiled eggs on hand, cheese snacks, individually portioned nuts, ham and cheese roll ups, etc.
Hope this helps! Good luck!!
