absolutely. remember you're eating lean proteins, and you'll likely be eating normal sized portions of them. the bulk of your intake will be from vegis...the calories you'll take in from them are negligible. The majority of your fat will come in form of oil for dressings.
if you do phase one then you'll likely be a real hard low calorie deficit...but full.
phase two will bring you closer to maintenance but still you should be at a negative.
Just as an example day
Breakfast:
8oz Tomato Juice
2 eggs
Snack:
Slice of bread\apple
Lunch
Peanut Butter w\ vegi's & 2 eggs
Snack:
2oz peanuts\apple
Dinner:
Salad w\ 2-4oz meat, vegis, oil
Snack:
2oz lowfat cheese
misc:
protien shake somewhere in there.
Equals out to:
Just at 2,000 calories
125g fat
118g carbs
120g protein
8 servings of vegis
2 servings of fruit
That's a pretty good bit of food, and not any attempt to stretch out calories at all. If you cut out the Apples and Bread you'd have phase I...right at 1,500 calories. That's IF you ate it all. Sometimes I didn't even clear 800 calories in phase one because I was full.
Typically I eat closer to 1,500c a day...I just made out this sample to give an idea for the future for myself with a set amount of calories and vegi's\fruit\grain intake that I wanted. You could easily adjust a bit here or there.
Try running out a sample menu of your own thru
www.fitday.com to get an idea of what you're looking at. It's REALLY easy to be full and stay really light in calories.
