I have been taking a whey protein supplement in the form of a shake once per day at breakfast. Every afternoon, like clock-work, I experience a loss of energy! I am completely off of caffeine so that is not a factor. My journal tells me that I've been pretty consistent with my three meals, and having protein with each meal.

This whey protein I have with breakfast has a HUGE list of essential and nonessential amino acids that it contains. It also contains a small amount of maltodextrin and sucralose which I am not overly concerned with since I am only on step 2.

When I eat more protein throughout the day, my energy does pick back up. But I feel like I am always eating when I am full in order to avoid this afternoon crash I've been experiencing. Could the amino acids or other ingredients in my morning protein shakes be facilitating this afternoon crash? Or is it more likely that I just have a need for even more protein, given the active nature of my job. Since I always feel like I'm eating when I'm full I plan on eating more protein dense foods so that I'm eating fewer calories while getting more protein. Thank you so much for any input/advice!
