Calories = calories is all you need to know. Unless * You care about your productivity or health, in which case getting sufficient balanced nutrition is important. * You care about body composition eg going on a diet is liable to lose you large quantities of lean body mass which sets you up for rebound weight gain down the track. * You are one of those rare people who are affected by hunger. If you are one of those people you might want to consider the effect of diet composition, adequacy and timing on your appetite. I also note: sample of one. Duration: 2 months (of people who lose weight over a 2 month period only a small fraction keep it off). Statistical significance: 0.
