I saw a movie about juicing and is it safe to only drink veggie juices for 60 days to lose weight?

Need protein and...: We need 40-50 grams of protein a day; if we don't get it from our diets we break down muscle, which is not healthy. I advise you also take a protein powder (from whey, hemp seed, rice or peas). As you lose weight it's important to get adequate vitamins & minerals to support your liver's ability to clear the toxins so a quality multivitamin is also advisable. Choose organic veggies. Good luck!
