There are a few reasons not to go too fast...
You'll still reach your goal, and the journey will be easier on you—plus your wallet will thank you!
When you keep weight loss at a gradual clip—usually about \(1\) to \(2\) pounds weekly—the collagen and elastin beneath your skin have enough time to adjust and tighten up while your body gets smaller. [

Drop weight too quickly and your system goes into shock, blocking that needed tightening and leaving you with sagging or extra skin. Going slower lets your body make the change in a natural way
And yes—shedding pounds too rapidly, which generally means dropping more than 3 pounds (1.36 kg) each week, can raise your chances of gallstones and pancreatitis quite a bit. [

When weight comes off fast (through crash diets, very-low-calorie plans, or bariatric surgery), your liver dumps more cholesterol into bile, and your gallbladder doesn't empty often enough—so sludge and stones can form. [

Yes, rapid weight loss can also strip away a lot of muscle. Some muscle loss tends to happen in any weight management effort, but when weight comes off quickly—often from severe calorie cutting—15–25% of the total lost can come from lean muscle mass
