interesting thread ...
First - that is no where remotely close to 700g of protein. Since we don't know the composition of the shakes he is probably around 160-180g of protein. For a person his size this is not too much.
Second - more fat is not neccessary. He is getting enough fat. The amount of fat you need to ingest to meet your essential need is very small.
Third - the OP does not complain he is hungry or going crazy from lack of variety. Yes - all of us would go crazy but apparently not the OP.
Fourth - It is not possible to eat too many veggies.
What is the problem? Lack of losing weight. Hard to say for sure but he is probably around 1500-1600 calories per day. That plus an hour of intense cardio means the OP is definately in a deficit. Thus - just like a lot of women - the OP is dealing with water. 3 weeks is not that long of a time.
To the OP-
You're not 26% fat. No way, no how. Bio impedence monitors are highly unaccurate. Also - 26% on a guy would be pretty chunky. Are you pretty chunky? For you to be at 26% at your height/weight you would have to have almost no muscle.
If you're happy with your food program than I personally have no issues with it. Assuming you're not lying about your food intake than I'd say you're probably going to experience a "whoosh" soon.
That said - depending on what your goals are - you should probably drop the insanity program and start lifting some weights.
iam mostly trying to lose the most fat as i can not worried about muscle ..right now.. I do drink lots of water .. so iam hoping that your whoosh theory.. would be correct lol..But today i had and eagerness to go on a one week fast.. i think this will fast track me in to the 200lbs wich is my goal... then I would be sure iam on the right track.. without the up and down scale..
