Here is another tip:
If you wake up with an almost metallic like taste in your mouth then you know you are on your path to losing fat and that your calories are low enough.
I woke up 175.3, lowest so far and I don`t think I will have to lower calories at all from 2600. I probably should increase them at some point and will probably in a little while. I can always predict when the scale will drop based on the activity that I do. Yesterday I dug a few holes and moved a lot of 50 lb plus rocks by hand for a few hours and this was after Heavy Leg Day and Triceps. 6 Sets of Heavy Squats, 4 sets of Cable Hack Squats for 20 reps each and 5 Sets Leg Curls. 5 Sets Close Grip Triceps, 5 Sets V Bar Cable Pulldowns and 5 Sets Straight Bar Pulldowns.
I knew I would see a slight drop on the scale after that and a bit more definition. Thats another good thing about being really lean is that even the slightest drop in weight is noticeable. The fatter one is, the less noticeable anything is.
