What do you do when you go to a place all day and are not allowed to bring in outside food and drink and they only serve junk? (Ie: amusement parks)

Sneak it in.

Or tell them you have a medical condition.

It's such a shame that we don't have some sort of official card that we show to say we have a medical condition.

Protein bars and fresh fruit.

Sneak it in. Lol. My doctor issued me a bariatric card I am supposed to carry on me at all times in case of an emergency so whoever treats me knows I'm postoperative malabsorption. But it can also be used when dining out. Maybe your dr has something they can offer you? Someone amongst the boards posted a website where you can print out a card an have your surgeon sign it. I forgot the info to the site though as I already have one. If all else fails.. My purse has become more of a vitamin/snack bag then a purse.

Protein bars and nut packs are small enough to carry in your purse. If the venue you are visiting will let you leave and return, then keep an ice chest in your car with any perishable foods.

I sneak in Snacks all the time. If you must get a bigger bag and hide them in pockets too.

I always sneak in Snacks, hide it in my purse stash good snacks in the car and I always take a large container of Water too. I totally forgot about my card that the Dr gave me but I have learned to order food the way I can eat it. If I am at a place that only serves hamburgers then I order it with out a bun in a cup.. and I have my stash of apples.

You can also take Protein shakes or drinks with you to help you over the time when every one is full and you know you need to get your every 2-3 hour meal in.
