Weight loss


I am 15 years old and want to lose weight.
I've always wanted to take weight loss pills, but I'm afraid they might affect my growth and development.
However, someone recommended Herbalife to me, saying it is a natural product that can be consumed by all age groups and has been approved by the health department.
But I'm worried about being deceived, so I want to consult a doctor.
Can I take this kind of product? Is it really not a medication? I exercise regularly, but it doesn't seem to be effective.
Is it appropriate for someone my age to take weight loss pills? Which weight loss pills can I take? Can I take that cool blue pill, or should I stick to Herbalife's natural products?

Dr. Ke Zhengchang reply Internal Medicine


Hello, A-Rong: At the age of 15, which is still a developmental stage, weight loss should ideally be conducted under the guidance of a physician and a nutritionist to avoid improper dieting that could affect growth and health.
Herbalife is a meal replacement approved by the Department of Health, meaning it can substitute for regular meals and is classified as a food product.
However, since you are only 15, it is best to have a nutritionist assess your daily intake to determine how to use it and how to combine it with other foods to prevent malnutrition.
Regarding the "cool blue pill," if you are referring to Roche's product, it is a medication.
Generally, it may only cause side effects such as diarrhea and oil excretion, but it is still not recommended for someone who is 15.
You may consider visiting a metabolic clinic and arranging for guidance from a nutritionist.
PS: Exercise and diet need to be approached correctly to be effective.

More Info


When it comes to weight loss supplements for teenagers, it is essential to approach the topic with caution and a thorough understanding of the potential risks and benefits. At 15 years old, your body is still growing and developing, and any drastic changes in diet or the introduction of supplements can significantly impact your health and development.

First and foremost, it is crucial to understand that weight loss supplements, even those marketed as "natural" or "herbal," can have side effects and may not be safe for everyone, especially adolescents. The body of a teenager is still undergoing significant changes, and introducing substances that alter metabolism or appetite can interfere with normal growth and development.
The supplement you mentioned, Herbalife, is often categorized as a meal replacement or nutritional supplement rather than a traditional weight loss drug. While it may be marketed as safe for various age groups, it is essential to consider that the long-term effects of such products on teenagers have not been extensively studied. The FDA does not regulate dietary supplements as strictly as medications, which means that the safety and efficacy of these products can vary widely.
Moreover, many weight loss supplements can lead to unwanted side effects, including gastrointestinal issues, increased heart rate, and potential interactions with other medications or health conditions. For example, some ingredients in weight loss supplements can act as stimulants, which may not be suitable for younger individuals.
Instead of relying on supplements, a more effective and healthier approach to weight management involves focusing on balanced nutrition and regular physical activity. Here are some recommendations:
1. Balanced Diet: Aim for a diet rich in whole foods, including fruits, vegetables, whole grains, lean proteins, and healthy fats. This approach not only supports weight management but also provides essential nutrients for growth and development.

2. Regular Exercise: Incorporate a mix of cardiovascular activities (like running, swimming, or cycling) and strength training exercises. Aim for at least 60 minutes of physical activity most days of the week. Exercise not only helps with weight management but also improves mood and overall health.

3. Hydration: Drink plenty of water throughout the day. Staying hydrated is crucial for overall health and can help manage hunger.

4. Mindful Eating: Pay attention to hunger cues and practice mindful eating. This means eating slowly, savoring your food, and stopping when you feel full.

5. Consult a Professional: If you're serious about weight management, consider speaking with a healthcare provider or a registered dietitian. They can provide personalized advice based on your individual health needs and goals.

In conclusion, while the desire to lose weight is understandable, especially during the teenage years, it is vital to prioritize health over quick fixes. Supplements may seem appealing, but they can pose risks that outweigh their benefits. Focus on developing healthy habits that will support your growth and well-being in the long run. Always consult with a healthcare professional before starting any new supplement or drastic dietary change.
