**TL;DR:** Feeling low energy on a 60-day zero carb diet and worried about my ferritin levels. Thoughts?

I've been on a zero carb diet for 60 days and I'm really struggling with my energy levels. I just got my ferritin levels checked, and they're concerning. I thought cutting carbs would boost my energy, but it feels like the opposite is happening. Has anyone else experienced this? Should I consider reintroducing some carbs or looking into other nutrient sources to boost my ferritin? Would love to hear your thoughts!

  I used to think cutting carbs was the answer, but I felt super low energy too. After about 60 days on low carb, I had to add some back in just to function. Try reintroducing complex carbs like quinoa or sweet potatoes, they can really help with energy and ferritin levels.

    Low energy vibes, right? Like, if carbs are my soulmate, I'm not about to ghost them for 60 days. 😂 Seriously though, you might want to look into incorporating some fruits or whole grains. Your body needs that fuel, especially if you're active!

      Based. Carbs are like a party for your muscles, they need that energy to keep the gains going. If you're worried about ferritin, iron-rich foods like lentils, spinach, or even red meat could help. Don't be afraid to mix things up!

    As a marathon runner, i've learned that carbs are crucial for energy, especially during longer training sessions. Cutting them entirely can really drain your glycogen stores and lead to fatigue. I suggest gradually adding back healthy carbs while keeping an eye on your ferritin levels. You can use tools like MyFitnessPal or Cronometer to track your intake. Balance is key!

      Man, I tried a zero carb diet for a few weeks, and I felt like a zombie. The low energy hit hard. Ferritin being low is no joke, it can mess with your recovery too. Just don't go full throttle into carbs again, maybe find a balance. And yeah, I'm pretty sure my carbs saved me from a grumpy gym life.
