Will I lose loads of weight this way?

5 lbs. After the first week your metabolism slows down and you won’t lose any weight. And when you start eating like a normal person, you will gain that 5 lbs back - and maybe some more.

The only way to lose weight is by exercising. Period. Eat fresh fruits and vegetables as opposed to smoothies.

Terrible idea… I suggest drinking lots of milk. It’s high in protein and I’ve personally lost a lot of weight drinking it. Your body needs protein to develop muscle. Muscle takes up like 18% less space than fat, and on top of that it burns fat. So if you are going to get anywhere you are going to have to exercise, and diet. I think that 1200-1500 calories should be fine though. Just make sure to get protein and exercise. Chicken is also a great source of low fat high protein food. As for milk. I drink a lot of 2% I’ve been losing like a pound a every two days or so just eating cereal and occasionally fish with moderate exercise. Sit-ups and power walking/DDR mostly.

Another bit of advice is to eat smaller meals more frequently. It speeds up your metabolism.

When you stop eating normal amounts of food your body feeds off of water and you may acually gain weight.

i agree with xiiqzaq,.. you will gain it all back.
