Not picking on you in particular, but i fucking hate this, sorry. Everybody has a diet; it's what you eat, and how much. Calling it a "lifestyle" change doesn't change the fact that they are changing their diet, and then calling the change by another name. I feel like this terminology just feed in to the "diets don't work." Which is complete bullshit. You always have a diet, and changing that diet will work, until you change it again. Sorry, just ranting.
