An unhealthy restriction is when a person severely restricts his or her food consumption in order to lose weight.
This form of dieting can result in disordered eating and a variety of health issues.
In addition to affecting your metabolism, insufficient protein intake can also result in muscle wasting.
Lack of protein makes it more difficult to develop and maintain muscle, which is essential for calorie burning and weight loss.
Although liquid regimens may appear to be a convenient way to lose weight, they do not provide our bodies with the essential nutrients they require.
As such, they cannot be maintained on a permanent basis and may result in malnutrition and health issues.
