Do not try to starve yourself. Neglecting to consume sufficient numbers of calories on a regular basis can result in the opposite effects you're looking for and, if sustained, can be life threatening. If you have attempted to lose weight by skipping multiple meals or drastically reducing your daily calorie intake, speak with a health professional about getting information on eating disorders.
If you feel negative side effects from your diet or exercise routine such as dizziness, nausea, weakness, pain, lightheadedness, headaches, or other symptoms, discontinue the program and resume normal eating or activity patterns. If you feel the pain or discomfort is severe or that your symptoms are worrisome, consult a health professional.
Do not begin a weight loss or exercise routine without first consulting a health care professional for advice. There are many health conditions that may contraindicate rapid weight loss programs or some of the other effective short-term weight loss strategies.
Losing weight too quickly is dangerous and can have adverse effects on your health. Despite the title of this article, getting into shape is best done slowly. Prolonged excessive weight loss can cause considerable health problems. The safest and most sustainable way to lose weight is to do so slowly and under the guidance of a health professional.
Avoid fad diets, diet pills, and "quick-fix" diet plans that severely restrict calories or food groups. Fad diets and techniques for rapid weight loss are not always effective, and some may be dangerous. Pills, powders, and diet programs that require extreme calorie restriction, total avoidance of entire food groups, or excessive exercise can be very hazardous to health. Pills and supplements are not monitored by the FDA and may not be safe. Unless you have a medical reason for avoiding a particular type of food, a balanced and varied diet is essential for adequate nutrition and healthy, steady weight loss. Diet pills and restrictive diet plans can cause nutrient deficits, organ damage, high cholesterol, and many other dangerous health problems.
Consult a physician or dietitian before adding supplements to your diet plan, as multi-vitamins and supplements are not necessary for everyone, particularly if you follow a balanced diet.
