The Challenge

Eat 800 grams (g) of fruits and vegetables a day. No foods are off-limits, but you only count your fruits and vegetables towards challenge points. Raw, cooked, canned, frozen; doesn’t matter!  If you can weigh it as a standalone and unprocessed fruit or vegetable, you can count it. What counts and does not count? The nitty-gritty rule specifics can be found here.
You can eat the fruits and vegetables you like while adhering to other nutritional targets. Your choices can be higher carb, lower carb, all fruit, perfect Paleo: it’s up to you.
So why 800g? It’s associated with increased health and is a simplified way to hit those recommended servings of fruits and vegetables. Read more here.

  • 2 points are awarded for eating 800 grams of fruits and/or vegetables in a day. You do not get extra points for any amount over 800g.
  • 1 additional point is awarded for “diversity”: when 6 or more fruits and/or vegetables are used to hit your daily 800g total (where each of these 6+ items has to have a minimum of 25g). Hitting 800g is a day is a prerequisite to being eligible for this point.
  • 1 point is also awarded for working out at CrossFit Roots (max 5 points per week). A run on your own or workout in your home gym does. not. count.


We will award one month of free membership to the person with the highest point total at the end of the 4 weeks. We’ll also have a few runner-up prizes.
