Hi everyone - new to site

Hi to all - I am new to this site. I've tried lots of others but this one seems to be working for my sisters so I'm trying it. I am 47, have high cholesterol and high blood pressure. I need to lose around 20 pounds. I've always been able to lose weight but as soon as I hit 45, the pounds came and I haven't been able to do anything about it. I desperately need motivation and support - anyone in? ? I'm starting a new "life plan" tomorrow morning - shooting for 1200 calories a day, lots of fiber and lean protein. Any suggestions on lowering cholesterol naturally would be greatly appreciated. Thanks!
