From past experience, I know the whole key to the next 30 days is proper planning. I have to plan to cook dinner each night, pack lunch for the next day at work, and plan emergency snacks so I’m not left at the mercy of the vending machine.
This go around, I knew I needed to stock the freezer and pantry.
Frozen vegetables and fruit.
Almond butter, coconut milk, local sweet potatoes and greens.
Whole 30 approved bacon. Finding sugar free bacon is next to impossible, but Whole Foods came through for me. Uncured so no nitrates. Always read the ingredient label, not the nutrition info. Look at the actual ingredients. Sugar is sneaky. 
As for the rest of my shopping trips, I stocked up on whole chickens, chicken thighs, pork shoulder and pork loin, flank steak, beef tenderloin. From the produce corner, I piled on more greens, green beans, mushrooms, zucchini, and lots of onions, garlic, lemons, limes, bananas, apples, oranges.
Next week is the big start. I know the first few days without sugar will feel like torture. But I also know how good it feels to get rid of the cravings that crept up during the holidays, as I knew they would and I enjoyed every bite. And still pulled on smaller jeans on Christmas day 
. This time, it’s not about weight, but feeling better and running/working out better.
