So I read this on webmd (http://www.webmd.com/diet/guide/high...-weight-loss):
"The Institute of Health's Dietary Reference Intake (DRI) recommendations allow for a wide range of protein intake - anywhere from 10% to 35% of total calories - for normal, healthy adults. For example, on an 1,800 calorie diet, you could safely consume anywhere from 45 grams (that's 10% of calories) to 218 grams (35%) of protein per day.
However, the Recommended Dietary Allowance (RDA) for protein is 56 grams a day for men and 46 grams a day for women. Most Americans have no problem getting this much, but would struggle to take in enough protein to make up 35% of their calories.
That said, is it possible to eat too much protein? There are no dangers associated with higher intakes of protein - unless you have kidney disease. To get the potential weight loss benefit, experts advise aiming for around 120 grams of protein a day. If you want to increase your protein intake, do it slowly over the course of a week. To be on the safe side, check with your doctor before adding large amounts of protein to your diet."
Which makes me think that sticking to a 1800/cal 218gr of protein wouldn't be impossible? I'm thinking you'd definitely use some sort of supplements mix (whey protein shakes etc) and loads of egg whites. But dang, you'd feel pretty full! I use a shake called VHP (very high protein) as a meal replacement and its quite tasty - 250calories/35g protein. The same company who makes it also makes other higher protein snacks.
