Potential side effects: Some medications carry risks that outweigh benefits for certain individuals.

Sustainable habits: Supplements and drugs work best when combined with healthy nutrition, regular exercise, and stress management.
Conclusion: Choosing the Best Weight Loss Solution
The best weight loss drug, medicine, or supplement depends on individual health status, weight loss goals, and medical history.

Ultimately, the most effective weight loss strategy is a personalized plan combining medical support, supplementation, and long-term lifestyle changes. Consulting with a healthcare professional is essential to find the safest and most effective solution.
