I'm trying to figure out the fasting glucose levels for athletes. I know that Schoenfeld and Phillips have talked about how glucose can impact performance, but what's considered a normal range? Also, are there any studies that show how this varies for different sports? Would love some insight on this!

  Dude, you can't forget about supplements! Creatine and beta-alanine can help with performance, but if glucose is low, it might not be as effective. You gotta optimize everything!

  Ngl, I was surprised when my doc said my fasting glucose was a bit higher than normal! I'm learning about all this stuff now since I'm cutting. I guess it's time to focus more on my diet.

    You guys are right! Balancing macros is crucial, especially for performance. For my lifting sessions, I focus on a good mix of carbs and protein post-workout to help with recovery and keep glucose levels steady. It's all about optimizing that energy for your next workout!

  Leg day impacts my glucose too! Gotta make sure I'm fueled right or else I get wrecked. So yeah, carbs are key for those heavy squat sessions.

  As a dad trying to balance everything, I just focus on keeping my energy up. I don't stress too much about exact numbers but definitely notice when I'm off my game. Just gotta keep it simple and get enough sleep!

  I've seen some studies suggesting that athletes, especially those doing endurance sports, might have lower fasting glucose levels. For example, elite marathon runners may average around 65-85 mg/dL due to their bodies adapting to higher aerobic demands. It's fascinating how our bodies adjust based on the type of training we do! Nutrition plays a huge role too, carb cycling can impact glucose levels and performance.

    I read a meta-analysis that found athletes in sports requiring high-intensity bursts, like football or sprinting, may see glucose levels around 75-95 mg/dL. It's interesting how specific sports really shape our metabolic responses! Incorporating nutrient timing might help maintain those levels during training.

      Totally agree! Supplements are just that, supplements. The foundation should always be whole foods and balanced nutrition. Also, hydration can affect glucose levels, so don't skip on water, especially during training.

        I guess it's a learning process. I try to pay attention to how I feel during workouts and adjust accordingly. Sometimes I think I could use more carbs, especially when I'm lifting.

    I keep a food diary to track what I eat and how I feel during workouts. Seeing how different foods impact my energy and glucose levels has been super useful. It helps me adjust my meals accordingly.

    That's interesting! I didn't realize athletes might have different ranges. I guess as a busy mom, I don't always think about that stuff, just trying to stay fit when I can

      This whole glucose thing is kinda wild. You really need to dial in your nutrition based on your goals. Honestly, i just focus on getting enough protein and staying hydrated.

    LOW KEY, I think some people forget that glucose isn't the enemy! Carbs are life for performance. Just make sure you're getting enough fuel, especially before intense workouts.

  From what I've read, fasting glucose levels can vary widely, but the general consensus is that below 70 mg/dL might indicate hypoglycemia, which isn't great for athletes. On the flip side, levels above 100 mg/dL could signal issues like insulin resistance. It's best to check periodically, especially if you're making significant changes to your diet or training.

    Absolutely! Carbs are essential for recovery and performance, especially for athletes. If you're on a restrictive diet, your glucose levels might drop too low, impacting your workouts. Also, don't forget about post-workout nutrition! A mix of protein and carbs can really help restore those glucose levels quickly.

  The normal fasting glucose range is typically between 70-99 mg/dL for adults. Athletes might have slightly different levels due to their training, but generally, they should still be within this range. A study published in the Journal of Sports Sciences noted that well-trained athletes could experience lower fasting glucose levels while still performing optimally. It's always a good idea to keep track of your numbers.

  I have chronic illness, so I have to be careful with glucose levels. Even minor fluctuations can make a huge difference in my energy. I'm always monitoring my diet and trying to find the right balance.

  Fasting glucose? More like fasting for gains! But seriously, keep an eye on it if you're training hard. Too low can make you feel like a zombie
