Why weight loss can be hard — and how Foundayo may help 😟➡️😊

Here are some possible reasons why you may have lost weight previously, but it came back:

You’ve been eating healthy. Working out. But it’s still hard to lose weight. And if you lose a few pounds, it’s hard to keep that weight off.

If this cycle sounds familiar, you may be surprised to learn it’s not your lack of willpower — your biology may be working against you 🧬.

When you start to lose weight, your body can react by:

• Making you feel hungrier throughout the day 🍔
• Increasing your appetite and cravings 😋
• Making you feel less satisfied after you eat 😕

The good news is there are more options than ever before — with many treatments that work with your body to help you lose weight, along with diet and exercise 💪.

It’s a great time to discuss a new approach with your doctor — one that may help break the cycle 👨‍⚕️.

You may need help on your weight journey 🤝

Did you know that people who partner with a weight management doctor could lose more weight than those who don’t?

If you haven’t been reaching your weight goals on your own, it might be time to work with a weight management doctor on a plan made just for you 😊.

Options could include:

• Lifestyle changes: A reduced-calorie meal plan and physical activity are an important part of any weight management plan 🥗🏃‍♂️.
• Weight management medicines: There are treatment options available to help control appetite and reduce hunger along with a healthy diet and physical activity 💊.
• Weight loss surgery: For some people living with an excess of body fat, this surgery (also called bariatric surgery) makes changes to the digestive system. It may control hunger and feelings of fullness 🏥.

The fact is, you don’t have to figure things out by yourself 💙.
