ARE YOU HUNGRY?
You want to know why you're not progressing?
You're not hungry enough, literally.
In order to be in a true caloric deficit to progress towards fat loss hunger has to be present.
The hormone Ghrelin is released during times of hunger which is ultimately telling your body you're not eating enough to sustain your body weight which ultimately leads to the body pulling energy from day sources to sustain itself.
You don't stop being hungry though.
Suck it up and embrace the discomfort.
Does this mean you should starve? Absolutely not! You need to be eating strategically.
