I have been feeling shaky, weak and tired! I don’t know what’s wrong In so tired! Could this be iron or low sugar?

You need more carbs. I know, funny thing to think about when your team has told you to limit your carbs, but, my guess is you have limited them too much. Gradually increase until the shaky/weak feeling passes.

Don't worry, you will still lose weight. My go to was cooked, mashed carrots. I know, I know ... but it worked for me.

I was like that - still suffer occasionally. If it is like mine it’s a sugar drop. I used to take diluted hydralite with me (it was too sweet at full strength) to give me that little boost. A couple of blueberries or strawberries also help. I remember being so exhausted at month 3 I thought I was going to literally fall asleep on my feet (well it actually was fall off my treadmill asleep after <5 minutes of walking). All understandable given our low caloric intake. The exhaustion does pass. Try having rolled oats for breakfast. They’re a good whole grain carb. I make mine on milk for extra protein. I could barely eat 1/3 cup until at least month 6 but it did make a difference.

Of course , if you are concerned check with your medical team. Better to be sure of what the cause is.

Add carbs. Try for healthy carbs though like fruit. I usually grab some berries or something or even a protein bar.
