I have used spike days to break a plateau. Basically, you shift your calories around so you have a weekly day where you consume A LOT of calories, and compensate the other days. I have a link on my bio page where I explain this in more detail. "My" system is based on this theory. It has worked wonders for me.

From October 4th 2010 to April 3rd 2012 I lost half my body weight - 80 kilos/170 lbs. Since then, I have had two cosmetic surgeries to remove excess skin. I have now quadrupled my strength, gained several kilos in muscle mass, and today I focus on building muscle, optimizing my diet, and living healthy. I am stronger, healthier, thinner, happier!
