First, ask yourself the following questions:
- Do I consume the right amount of calories?
- Do I weigh individual ingredients?
- Do I drink plenty of water?
- Do I workout as much as I should?
- Do I feel more stressed than usual?
- Do I get enough sleep (7-8 hours)?
Any question you answered 'no' is likely a reason why you are not losing weight. Make sure to pay more attention to your daily routine and stress levels.
