My most recent blog post details my weight gain progress. This represents 6 weeks using variations of my recipe. I increased macros on a weekly basis, recalculating them based on my new weight. I achieved an average weight gain of 3.6 lbs/week.
Measurements taken before sleep and upon rising under conditions as similar as possible with some exceptions.
During this time, real food “bonus” calories were consumed occasionally but shakes were always consumed.
