I have lost 30lbs this year and even the difference between .5 and .7 is noticeable to me.

There is also the variable that you can work out too much. I did a brutal 30 minute glycolytic conditioning session on Friday and it just doesn't matter how much protein I consume the next day. Something with ghrelin goes off the chart and the next day takes huge will power to not just eat everything.

I think it is even worse with max effort weight lifting.
