Weight issues

I was watching "Good Morning America" this morning and Dr. Oz was on { you know the Doctor from Oprah} talking about weight and what your ideal measurement should be.

Here is his theory: your waist measurement from your navel area should be half of your height. For example if you are 5'6 " your waist should not be bigger than 33 inches. Well I am 5'8" inches and I am under 34 " for my waist but lately I have been feeling fat . I just need to go out and walk and do some exercise ..but we have too much snow and ice--- and right now I have no money for a gym membership .

I think its that winter dull drum where all I feel like I do is sleep- shower-eat-poop-work-sleep !!

Does anyone else feel this way ? Do I have that winter syndrome where I need a light lamp and some retail therapy?!!
