Hi anais...
Yes, there are things you can do. First of all, those mixes are WAY too expensive for most of us to bother with, so I don't know too many who really use them. There are plenty of other things to cook with "legally"...
On induction especially, you want to stay away from bars, shakes, mixes, etc. The real staples of this type of eating is meats, fats and veggies...and ZIP LOCK BAGS!! If you know lean days are comin', get ready... you can make this very inexpensive. (I'm a starving student, I can relate!)
I usually catch chicken breasts on sale and stock up. Yesteday I found a HUGE beautiful cauliflour for $1.59 and cut it up and froze it. When fresh hamburger goes on sale, look out...I have it wrapped in one pound packges, and I get 3 big burgers out of it.
Burgers with a little blue cheese dressing is often a late breakfast for me when I don't feel like eggs. It can be tossed around the pan with leftover veggies and some butter and spices, etc. Be creative...no one said breakfast couldn't be lunch meat!
Now CRAVINGS...yes they went away for me after a while, but it took a lot of detoxing because I'm a carb addict truly. My body went into shakes without that stuff!
You can make yourself some sugar free jello w/whipping cream, or when you're over induction you can make a LC cheesecake and freeze individual pieces, etc.
Just tell yourself that you are learning (slowly, day by day) how to turn your old menu into a new, healthier one... there are PLENTY of LC desserts you can eat when the urge hits. Recipes for sweets and fun foods are all over this forum!
But for me, I try to keep them to a minimum because it's also the emotional eating and reaching for a "treat" that I"m trying to discourage.
Stick around here as much as you can...you'll find people (like me) whose first thought about Atkins was, "I can never eat like this the rest of my LIFE!!!"
It's so funny now, because I can't think of any other way I could possibly eat for the rest of my life...it's just taking some learning and adjustment...and NO frustration...just determination.
You're doing great....hang in there and find a way!!
