Ive low carbed while at WDW - it's a will power tester, but it can be done. I did it...
At Ghiradelli's in DTD, they have Sugar Free Almond Clusters - fabulous. Now, Im sure theyre not on the plan, but regardless. They made me low-carb'ing MUCH MUCH easier. I ate one everyday for breakfast.
Everywhere that has pasta - they will substitute for a HUGE amount of asparagus, broccoli, whatever they have.
Dont do what I did - go to the food and wine festival, get lit, and decide once youve had every wine around the world - youre gonna have Chocolate Covered Strawberries. My ONLY cheat and my belly hurt SO bad!
Good Luck to you- it's hard, but you can do it!
