im over weight, and need a fast, effective way to work out?

well you need to start light, and gently work into a normal workout routine. Start by walking, then increase weekly. eating right and staying active are the keys. It's a good idea to see a doctor first to see if it's not related to something else more serious. they can also recommend a specific way that may work for you

I'm 5'8 and 129 lbs and I set my calories at 1700, carbs at 225, fat at 50 and protein at 70.

I thought I ate pretty well, but one I began tracking it I realized that some days I ate up to 70 grams of fat.

This plus working out 4 days a week has really helped me stay on track. Don't waste your money and time on gimmicks like liquid diets and pills, they don't work. Get a sensible eating and workout plan and stick to it and it will work!!
