Could be, I suppose.
Perhaps demand has outstripped supply.
As one who went to this type of diet in April, I can tell you that my food bill is up 40%. It's a lot more expensive to buy beef, fish, cheese and eggs than it is to buy pasta, bread, rice and frozen pizzas. It's not cheap getting all those fresh vegetables, yogurt and berries either.
But it's worth it to me. My health situation has done a 180 degree turn in the past six months. I feel 10 years younger - only 20 years poorer! If only fresh cod and prime rib didn't cost $7.99 a pound.
