Don't shy away from the grocery store
Even though it's bitterly cold out, and you're afraid the howling wind will freeze you into a human icicle, you can't always order delivery to nourish you through the winter. Get up the courage to do your grocery shopping, just as you would at any other time of year, and you'll have a much easier time keeping the pounds off (not to mention getting in some physical exercise from walking around the store).
