Why Is It So Hard to Lose Weight?
One of the reasons why it's difficult to lose weight and keep it off is because changes in appetite hormone levels make it difficult to do. When a person loses weight, their body’s natural response includes an increase in a key hunger hormone and a decrease in fullness hormones, undermining the ability to lose weight and keep it off.
Trying to lose weight can feel like swimming against the tide
Healthy eating and being more active are both important parts of a weight-loss plan.
But an adult study has shown that after weight loss, changes in appetite hormones in the body push back against people’s progress, making them feel less full and increasing their appetite.
These changes can work against efforts to keep weight off, making it difficult to prevent weight regain. But with the support of a health care provider, you (or your teen) can find ways to combat these obstacles.
Losing weight is possible
While it may be difficult to lose weight and keep it off, it can be done. It all starts with a plan. Here are some helpful tips:
Change your approach
- It’s not about finding a quick fix—it’s about focusing on your ongoing weight loss and weight management
- Increasing your physical activity and building a reduced calorie meal plan that fits your lifestyle are key to reducing your weight
Take obesity seriously, just like other chronic diseases
- Losing weight and keeping it off requires a long-term plan
- If meal plan and physical activity changes alone are not enough, you may require medical intervention
Start with small steps
- Choose what you are willing to do
- Make it a part of your daily routine
- Take it 1 day at a time
- Work with your health care provider to create, monitor, and adjust your weight-management plan

What are the possible side effects of Saxenda®?
Saxenda® may cause serious side effects, including:

Dehydration may cause kidney failure, which can lead to the need for dialysis. This can happen in people who have never had kidney problems before.
