Fat tissue goes valhallavitality.com/.../tirzepatide-vs-semaglutide-which-weight-loss-drug-takes-the-cake when there is a caloric deficit. In other words, when the body expends more energy than it consumes. There are two ways to create a deficit: reducing your daily calories and increasing your physical activity.
That means you can reduce your food portions and start losing weight, but not exercise. Or you can eat fast food and work off more than you ate by exercising. In both cases, you will lose weight. The body, not getting enough calories, will start taking extra energy from fat reserves.
