I don't know how to post photos, otherwise I'd help you out!

When I travel and bring food from home, I take stuff like sturdy fruit, nuts, jerky when I lived in the US--over here in the UK, it would be biltong (same thing, really) if I can get it.

Depending how long I'm going to be away from a decent meal, and what the situation will be like as far as it being convenient to eat, I might bring a baked sweet potato or a salad, etc.

I am house sitting this week, so I'll be cooking for myself, and brought my low carb/no carb/gluten free stuff with me. Coconut oil, some tallow, some duck fat, coconut flour, almond flour, raw milk, pork belly, chicken livers (oh yes, I went there!), and tons of veggies. I will have plenty of access to grass fed beef, some chicken, and plenty more home grown veggies from their garden. I am well set to keep my low-carb journey going strong. Not only that, I have animals to tend, and a doggie to walk. And possibly even a bike to ride.

For traveling on the road, you cannot beat the humble boiled egg. Oh yes. Veggie sticks, boiled eggs, trail mix, beef jerky, etc.
