It seems like every year I shed some weight going into summer but it is kind of odd. Within a weeks time I have dropped about 10lbs. I have been going nuts trying to put the weight back on but my body doesnt like to hold weight. I have switched from eating cleaner home cooked meals to eating two big macs with fries for lunch and I have been adding large amounts of olive oil to my shakes I have twice a day. I have seen no change. How can I go from eating clean to eating this dirty and not even gain a pound? I am not some gifted guy who has 8% body fat and a fast metabolism either.
