Unfortunately when many people come to the realization that they are carrying too much condition, they have tipped the scale far more than they would have liked.
Panic then sets in and the need to lose it quickly, generally prior to a special occasion such as a wedding, becomes a priority.
It then becomes a race against time with the person seeking out a diet, exercise program, pills or medical procedures that will help them achieve their goal.
Unfortunately although they will work if given enough perseverance, many of these will leave one hungry, lifeless and completely lacking energy.
Moods are then affected with the person becoming irritable and intolerant of those around and thus usually causing the person to quit.
The most effective method to lose weight is not to crash diet but to implement a lifestyle change consisting of good eating and exercise habits that will help you lose the weight and keep it off.

• Enjoy your food.
  Eating should not only provide a source of nutrition but should be enjoyed.
  Choose healthy, nutritional meals that you enjoy eating.
  One will not stay with a healthy eating plan if the food is bland and tasteless or worse, downright horrible.
  Limit foods that have a high calorie or sugar count that provide little or no nutritional value.
  
• Eat a good breakfast.
  Do not think that you are cutting calories by skipping breakfast as chances are that you will be ravenous later in the day causing one to choose high calorie meals that usually have little nutritional value.
  People who eat breakfast are more likely to have higher energy levels and consume more vitamins and minerals and less fat during the day.
  
• Choose water as your desired beverage.
  Whilst juices and milk provide a high nutritional value they are normally high in calories.
  Regular soft drinks are viewed by most nutritionists as 'empty' calorie foods that provide no nutritional value and have high calorie and sugar content..
  Whilst it has been shown that drinking alcoholic beverages in moderation can provide some health benefits they also have high calorie content.
  
• Exercise regularly.
  This is of the utmost importance as muscle development has been shown to be conducive to lowering the body fat content.
  It is therefore necessary to add resistance exercises to your program.
  It is of little value to try to lose weight whilst maintaining a sedentary lifestyle as it is the percentage of body fat, not necessarily our overall weight, that we should be concerned with.
  

Most importantly if you blow out on the chocolate cake do not feel like you have failed on your quest for a lifestyle change.
Pick it back up where you left off, it takes time to implement new habits.
