Wow that’s hard.
You don’t want to lose the momentum you’ve got started, not to mention all that weight you’ve lost ( I would love to see that bumble bee hit 200!). That camp food does not sound very healthy, much less diet food.
What kind of camp is this? Do you have access to a microwave/fridge or is this tent camping?
The only advice I could give you is from my personal experience. When I was in the Navy, we would be out to sea for months at a time. The food being prepared was not the healthiest in the world, especially if I was trying to lose weight or stay healthy. I would stock up on lean cuisines, in our shop frig and cook them in our microwave, among many other low calorie/healthy meals.
If you don’t have access to a fridge or microwave you could:
-Bring a lot of fruit
-Buy some kind of powdered drink
-Bring your own Camping Stove/Pot and lots of soups
There are lots of “Healthy Choice” soups out there that are decent on calorie intake, healthy and will fill you up.
Ill keep thinking on this one and post any new ideas.
Best of luck to ya!
