I've got to be straight with you, I'm not posting about juicing. Mainly because I can't afford a juicer, I've never seen one for less than $100
Because I'm destitute, smoothies are a great alternative (blenders are cheaper, I got one for like $20 and it works wonders), because you get fruit and you can add dairy with milk or yogurt, vegetables like spinach, protein powder, and other extras like flax or chia seeds.
However this site: http://nosugarsweetlife.com/content/juicing-weightloss-improved-health-and-nix-sugar
has some great tips on juicing!
