There are a lot of people on here who have been brain washed by the diet industry. They love the restrict/ half starve to drop lots of weight and then bounce back to a bit heavier. The amount of disordered eating threads on MN makes it resemble a pro ana site at time.
The concept of changing how you eat, to change your gut biome and become healthy is quite alien. Mind you it is bloody hard to change your whole way of life and the results are very slow. People like quick fixes.
