From my experience last year.

1) From an energy standpoint this Fri-Tue will likely be the most difficult. We’ve drastically cut carbs (some people more than others) and have burnt through our glycogen stores. During the metcon you might feel sluggish, or low energy in the afternoon. We normally replenish these glycogen stores easily with starchy carbs. Going strict paleo makes that difficult as the only allowable source is sweet potatoes/yams. A good way to fuel performance for a metcon is to eat some starchy carbs pre (1 hour prior) and post (as quickly as possible). Starchy carbs are higher in glycogen, your go to is yams/sweet potatoes. Fruit isn’t a great option because the main carbohydrate is fructose. The fructose to glycogen metabolic pathway isn’t as efficient as glucose to glycogen. Remember Lurong still recommends 150 grams carbohydrate for a 150 pound person.

On top of the decrease in carbohydrate intake, calorie intake has likely decreased. Be certain to still eat near your daily recommended caloric intake.

2) We all have a sweet tooth. My biggest recommendation is dehydrated mango or pineapple. Trader Joe’s sells both. Be sure to read the label to make sure there is no added sugar. Dates are very sweet and tasty. Homemade Larabars are great and easy (http://stupideasypaleo.com/2012/04/29/lara-bars/). You can use flavor extracts. My favorite was a chocolate mint and chocolate coconut larabar. Make sure to use 100% cacao powder.

3) Those of you that have a soda craving find yourself a fitaid or kill cliff. Both are decent, approved alternatives. Another option is Zevia, a naturally sweetened soda. They use stevia (listed as Reb a on the ingredients) and erythritol which are Lurong approved.  There are a few flavor options, be sure there are not food colorings etc. on the ingredients.

4) After week 2 paleo will become automatic. At that point you’ve decided to eat paleo 42 times (14 days at three meals a day). You’re well on your way to forming a habit. It will be those times you’re unprepared that’ll cause you to cheat. Woke up late and didn’t have time to pack a lunch…etc. Keep it simple and prepping will be easier and the likelihood of cheating will decrease.
