I mentioned in my last post some items that could help you in your weight journey.
If you don't have access to a refrigerator where you work (or perhaps you are on the road most of the time) then I highly recommend a small cooler with some cold packs. Another option is this:
A freezable lunch bag commonly know as a Packit. The whole bag folds down to fit nicely in your freezer without taking up a lot of room. You freeze the bag and then pack-it and it will keep your items cool up to 10 hours.
So you don't need a refrigerator and you can't say "I have no way to keep things cold." Yes you do!
If you don't have access to a microwave, hot plate, toaster oven, etc.., then obviously you can't pack something that needs heated or cooked - but you do have the option to pack ready to eat things: sandwiches, yogurt, carrots/celery/tomatoes/fruit, etc.. Don't use excuses, make it work!
