I was tracking my calories & nutrients precisely & keeping them exactly at the recommended levels (C50%, F30%, P20%); I plateaued. Upping my exercise didn't get the scale moving, so I increased my protein a bit. While my caloric intake remained the same, the nutrients fell at 43.76%, F 27.37%, P28.87% & so did my weight. The next day I'd lost a full pound, as well as the following day (although I didn't keep my nutrients at the adjusted levels mentioned).
I plan on going back to the recommended levels (C50%, F30%, P20%) today.
Please remember to drink all your recommended water & then some if you increase your protein.
