I like dialtone am around 250lb 5'9 and I have been experimenting with this idea of 1.5g of protein per lb of bodyweight. I have done what the weight loss "gurus" say is good for losing weight
1. drop calories
2. drop fat and carbohydrate consumption
3. excersize
Those three in combination with a high protein diet (Does this sound just like soth beach? I haven't read the diet personally) have not produced any drastic results for me. Yohimburn has been somewhat successful for me , but this idea of chomping down large quantities of protein personally has not worked for me.
I cycle 8 different protein powders in the last say 5 months on top of regular meals.
1. isopure
2. nitrotech
3. mgf-2

4. iso-agb
5. ON 100% whey
6. Now Foods soy protein Isolate 90% non-gmo
7. cytosport evopro (nighttime micellar casein)
8. ultimate Nutrition massive whey gainer

If you want to waste your $$$ , then that's on you. I've been wasting mine in an experiment and the hypothesis is that it makes you hold onto fat and it lesses the $$$ in your bank account. It's made no real difference in terms of gains in the gym.
