I tend to eat a ton of fruits & vegetables as part of my "meals" so I won't include those as "snacks".
- Dates
- Figs
- Nuts (raw, shelled & unsalted)
Speaking of dates, if you've never had them stuffed with goat cheese, you're really missing out on something special.
If you're an active person, you'll be able to consume more water. However, even hiking a rough trail for 8 hours in the scorching sun (95 F) & horrendous humidity (85%+), a 3-liter CamelPack will typically suffice (for me). My guess is that Anthony is extremely active or he's merely drinking too much water, as he stated.
