In order to lose weight you need to asses your efforts intake. Food is used as energy for your body, and any energy not used is stored as fat. It is therefore essential that you only take in the particular you need and increase your activity level in order to lose weight. When cutting your calorie intake, it is essential that you make changes that you are likely to stick to as crash diets may lead to 'yo-yo' dieting. Eating around 300-500 calories less a week will lead to a weight loss of 1-2lbs a week, while it is not much once a week it adds up to around 52lbs annually. It is also important not to skip meals as this might cause you to overcompensate later in the day and goody more. Increasing activity levels can be done easily for example trying to do 20 minutes of walking a day, such as walking short into adulthood than using the car. By finding something that you enjoy you will probably adhere to it.By using a weight loss program you can implement these changes and stick to them. It may also work best if you write your plan down, keeping a note of your targets, changes in weight and achievements to help you go on track. Whilst you may not see any immediate changes, stick with it. Never allow any weight gain put you off, and instead look at your program and see if anything needs to change, such as boosting your activity levels.
