People often try to lose weight through dieting, but this could sometimes be bad for their health. Here is a list of some of the diets and the side effects they may have on the human body.
Low calorie diets
When people follow such diets, they can lose 3 to 5 pounds of their weight every week. This weight loss can improve problems related to obesity including diabetes, high blood pressure, and cholesterol. In the first 3 to 6 months people will lose15 to 25 percent of their weight.
A very low-calorie diet is a prescription diet indicated by the doctor. The diet formulas are commercially prepared to reduce weight for treating obesity. These formulas need to contain appropriate levels of vitamins and micronutrients. Some doctors also recommend lean protein food such as fish and chicken in diet. You need to consume 800 or less than 800 calories per day in this diet.
Most of the people who follow this diet plan may have some problems, including fatigue, constipation, nausea, or diarrhea. Rapid weight loss may result into cholesterol problems. That is why most of the people who are overweight should consult the doctor before following this diet. Doctors will encourage you to proceed with the healthier diet and regular physical activity.
A crash diet is used every year by thousands of men and women who want to get rid of a lot of weight in a short period of time. It is a highly restrictive form of dieting, which entails severely cutting the calories and fat that you eat every day. It is usually compared to a starvation diet.
In most cases a crash diet goes hand in hand with another form of weight loss. That can be an extreme exercise routine or a diet pill. It must be made clear that many specialists and health care professionals have proved that this method of losing weight is accompanied with dangerous side effects.
The nutrition deficiency can have its side effects on various different systems in the body. You will not be able to eat healthy food as a result of the restrictive nature of the diet. The long-term effects of this can result in serious nutrition deficiencies that will harm your digestive system, skin, heart, liver and kidneys. Some of the most common conditions connected with this type of diet are iron deficiency, vitamin B 12 deficiency and potassium and sodium deficiency. The most dangerous among those is potassium and sodium deficiency, which can lead to a heart attack. The lack of electrolytes hinders your proper muscle and nerve functions and thus affects your normal heart beat.
A crash diet results in extreme food cravings that can completely occupy your mind while at work or wake you up in the middle of the night. Furthermore, this diet affects your mood. You become more irritable and experience mood swings. The related feelings of depression can gradually lead to the development of more serious mental disorders such as bulimia and anorexia.
In a nutshell, it is really important that people consult with a doctor before going on a diet. Otherwise there could be serious consequences for their health.
