You Feel Full Longer After Meals
GLP-1 medications delay gastric emptying, which means food stays in your stomach longer. If you’re noticing that you're fuller after smaller meals and staying full for extended periods, that's a clear sign the medication is working as intended.
Your Appetite Has Decreased
Another early sign is a reduced interest in food. Many patients find that cravings, especially for high-calorie or sugary foods, begin to lessen. This appetite regulation is one of the key ways these injections support weight loss.
Your Portion Sizes Naturally Shrink
You may start leaving food on your plate or finding that your usual portions feel like too much. That’s because GLP-1 medications influence satiety signals, helping you listen to your body’s natural cues.
Mild Gastrointestinal Changes
Some people experience side effects like constipation, which occurs due to the slowed digestion process. While not comfortable, this can be a sign the medication is doing its job—just be sure to hydrate and add fiber to your diet.
You're Losing Fat—Not Just Weight
Over time, as your appetite drops and your body adapts, many clients begin to see changes in body composition. Weight loss injections support fat loss (not muscle loss), especially when paired with protein intake and light exercise.
Weight loss injections work in subtle but powerful ways. From reduced hunger to better portion control, the early signs can be easy to overlook—but they’re important indicators that your body is responding. If you’re unsure about your results, our Pure Skin providers are here to guide you every step of the way.
