It is highly unlikely to lose 2 kg of weight in a single day in a healthy and sustainable way.
Here's why:
- Water Weight Fluctuation: The majority of weight loss within a day is likely due to fluctuations in water weight. This can occur due to factors like dehydration, changes in sodium intake, or even bowel movements.
- Fat Loss: Fat loss is a gradual process that happens over time. It's impossible to significantly burn fat in a single day.
- Muscle Loss: Extreme weight loss in a day could potentially lead to muscle loss, which is not desirable for overall health.
Losing weight healthily and sustainably should be a gradual process that involves lifestyle changes, including diet and exercise.
