Designing a logo is difficult because too many elements can become distracting. In my opinion, my design with the fork/knife and the runner is too distracting (#52). Out of the logos I've designed for you, I prefer
#44. This logo is very clear, concise, and to the point. I think 44 is more likely to catch people's attention because it suggests movement (and the eye is naturally drawn toward movement).
I think the key to creating a good logo is representing the most important element of the company in that logo. The forks and knives may look good, but they are very generic and could represent any restaurant, food service, etc. Your service is different than other services because it tells people to eat the caveman diet and it targets athletes. Therefore, I think you should decide which of these two elements is most important to your service and make that element the fundamental part of your logo.
I hope this helps with your decision process.
