We all know someone that is on or has done crash diet and has lost weight fast.fantastic if only dieting was that simple there would be no need for food and we could all live off shakes happily ever after!
If you are considering going onto a crash diet to lose weight fast here’s some things you may want to think about
slow down your metabolism: the rate at which your body turns food into energy
prevent you from getting important nutrients and vitamins that your body needs to work properly
reduce your intake of carbohydrates (such as pasta, bread, and rice) that are an essential source of energy
increase your intake of protein and fat: too much saturated fat can raise your cholesterol and increase your risk of heart disease and stroke
Can also lead to depression
Eating disorders such as anorexia or bulimia
short-term dehydration and nutritional deprivation, can go hand in hand. Even if you consume a lot of water throughout your diet it is hard for your body to retain water if you are not eating balanced meals. Severely reducing your caloric intake deprives your body of vitamins, carbohydrates, proteins and nutrients that it needs to sustain itself. Having a diet low in fat is good but having a diet free from fat is not acceptable, your body needs 30% of its daily calories to come from fats. In addition, a lot of crash diets suggest the use of laxatives or salt water flushes which increase risk of dehydration and don’t allow the body to absorb nutrients and fats which in turn leads to nutritional deprivation.
long-term health complications that can arise from excessive crash dieting, or yo-yo dieting. They weaken your immune system,
cause heart palpitations and cardiac stress. If you do one crash diet you may not hurt your heart but if you crash diet repeatedly you can increase your risk of heart attacks. Crash diets also lead to heart muscle loss in the long run. You damage your blood vessels when the muscle shrinks and grows and the micro tears create an environment perfect for atherosclerosis or other types of heart disease.
