I've read on here from a few people that you should take about 150% of your weight in protein per day. If I weigh 275lbs I guess that means I should be consuming roughly 400g of protein daily. Any suggestions about what foods might help me consume this much daily? I am trying to eat more chicken, fish, and get some powder for shakes. I've never had them before, but I was looking at Designer Whey Protein Powder for the protein shakes.. anyone had those or prefer others?

You trying to build more muscle or lose weight?

At this point in time I need to lose weight

Then I wouldn't go quite that high. 150% weight in protein is more conducive for muscle building. You can get away with significantly less while losing weight. The best way to figure it out might be to figure out about how many calories you need to eat daily for steady weight loss (identify your BMR as a starting point). Then take 25 to 30% of those calories for protein, 40 to 50% for carbohydrates and 20 to 25% for unsaturated fats. It's an easier way to get a good balance of nutrients as you lose weight, but still get enough to maintain you current lean muscle to keep metabolism high.
As far as high protein foods, lean meats like chicken and turkey breast, fish (even fatty fish is healthy), eggs, soy, beans/legumes, dairy (milk, cottage cheese, natural youguts), occasionally very lean beef, and if you want to get a little saucy, game meat like venison and elk is very high protein. A super quick protein fix is a can of tuna. 37g of protein, 1g fat, 0g carbohudrates, 150 calories and 50 cents. Can't beat that. :)
If you still want to use whey powders, Designer is okay, but you get more for your money going for the 5 lb tubs like Optimum Nutrition. Check online shops like DPSnutrition and Netrition for good prices. It pretty much comes down to taste. Maybe try a smaller can of something to see if you like it before getting a larger one.

Naxis.. thank you for the invaluable information, it is much appreciated.
