It's excellent that you're motivated to achieve your weight loss goals. If previous methods haven’t worked, various factors may contribute, such as metabolic rate, hormonal imbalances, or lifestyle habits. Focus on a balanced diet rich in whole foods, incorporate strength training, and ensure adequate sleep. Staying hydrated is crucial, so aim for consistent water intake. If you're feeling tired frequently or still struggling despite your efforts, I suggest consulting a bariatric surgeon. They can assess your overall health and suggest personalized strategies to help you achieve your goals more effectively.
