Has anyone else experienced this &/or do you have any guesses about what might be lacking in my diet.

I had a baby in Feb 2002 & started LC'ing in July. I've always been in good shape (even though I was 10-15lbs overweight) & I worked out every 2 days while pregnant.

I notice that lately I'm way weaker than I was before starting my LC plan. When I was pregnant I could lift 20lb dumbels for bicepts (although I limited myself to 15lbs so as not to overwork myself). Now I cannot do a full set of 15lbs, & even 12lbs feels challenging.

I also notice my shoulders are more sore than they used to get & I sometimes skip working out my arms to give them more recovery time.

Although I used to eat healthily before LC'ing, a huge part of my nutrition used to come from breakfast cereal (cornflakes, weetabix etc.)

I'm wondering if any of you think my weakness might be due to a lack of B vitamins and some of the other nutrition additives in cereal? I'm doing the Montignac method & he doesn't recommend supplements.

Does anyone have any suggestions?

One other thing - I'm sure I'm getting enough iron, even though my symptoms seem consistent with iron deficiency.
Thanks
