How long would it take to lose 2 stone and what would you have to do . ?

6-12 months: The key to losing weight is not a temporary diet but permanent changes. Sugars ; simple carbs from grains esp. Cause weight gain. Avoid fried foods. I like dr. Furhman's diet: http://bit.Ly/1dhw9ht dr. Weil has useful info: http://huff.To/19ygs8y- see his "discuss that" link in his article. Exercise is also important! the less you eat ; the more you exercise the faster you'll lose.
