If I go to a diner, they’ll generally prepare food the way I ask. But fancy places have chefs that get “offended” when I reject their “preparations” (which are fat and salt, basically).
The more one eats out, the more likely one is to gain weight. Therefore, I grocery shop (with a list; after eating a meal, so that I’m not hungry ); I cook; I save money; I maintain my weight loss. 212 lbs this morning, vs. 337 lbs at my greatest.
