Glasgow east is quite bad yes, but its a tiny proportion of Glasgow.
Its just like anywhere else, you have your good parts and your bad.
I live in Glasgow and my area was named few months back, the best place to raise a family in the UK.

Also gives a list of the ten worst at the bottom.
Most of the people there are unemployed and so dont lead very healthy lifestyles.
I dont agree with the comment on the weather as I live in Glasgow and no one I know would let the weather get between them and going out! But then I haven't ever met anyone from Glsgow east so you may be right.
