I make a mix of protein powder, MCT powder, coffee and milk powder. Very effective and long lasting.
Nuts and biltong, hard cheeses, electrolytes are essentials. I like 99% dark chocolate from Lindt but that’s just me…Rusks made from Almond flour at Woolworths is also a good option if you are a big coffee and rusks fan like me, and they have several low/no carbs seeded crackers and bars available.
(Remember to take some carbs for a targeted keto approach.)
If you want to take meat double vacuum pack wrapped in newspaper, place that inside a tight fitting plastic bag. I found that it lasts for up to 5 days and never had a problem. It may smell a little funky when you open it on the 5th day but it is still fine. Just don’t expect wors to last that long. It may surprise you on day 3 already!
John West with Burger King mayo sachets are also a good alternative.
