We love nuts and they are decidedly paleo diet friendly. Be careful though, as cashews are high in fat and, for some reason, it’s incredibly easy to eat an entire jar of them in one sitting (that’s not just us, is it?). If you’re trying to lose weight, limit the amount of nuts you’re consuming. Otherwise, have at it. I mean, you can’t beat a good almond/pecan/walnut mix, can you?
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
People who never had good social group experiences like it because, even if they are crazy, CF communities are always positive, supportive, and good-natured. CF brings people together and makes them compete every day in a society that shies away from competition. The challenge creates a heightened sense of self worth that develops into being an elitist..
My favorite part of CFA are the people. Everyone that I workout with are so motivating, fun, and down to earth! The coaches, wow YALL ARE INCREDIBLE!! Always so helpful and encouraging! People always ask how I am able to go and workout at 5:30 or 6:30 in the morning every day? And it’s because I’m excited to see everyone!! Having a family like this is so amazing!
Following the paleo diet can be pricey. Inexpensive and healthy non-meat protein sources like soy and beans are off-limits, and a recent BMJ Open study shows that healthy meats like lean ground beef and boneless, skinless chicken breasts cost an average of 29 cents more per serving compared to less-healthy ones, such as high-fat ground beef and chicken drumsticks. Even switching from peanut butter to paleo-approved almond butter will cost you—it goes for up to $13 a jar.
Additionally, “while the paleo diet has plenty of protein and fiber, it is sorely lacking in calcium and vitamin D, mainly because of the omission of dairy products,” Roger Adams, Ph.D., founder of Eat Right Fitness, previously explained to Men's Health. Over time, this could weaken your bones and immune system, which makes it important to eat plenty of calcium-rich (and paleo-friendly) foods like broccoli and dark leafy greens.
CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of which are located in the United States, and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day"). CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.
