Weight loss is the reduction of an individuals total body mass (body weight). The body weight of an individual can be a combination of fluid, lean mass, muscle and fat loss.
Many factors can contribute towards weight loss. Weight loss can be unintentionally caused by a disease or intentionally by dieting fat reduction,or exercise.
Weight loss and calorie consumption
Calorie consumption can have an effect on weight loss. The average male has a daily calorie limit of 2500 calories and for a female it is 2000 calories.
A pound of fat is the equivalent of 3500 calories. In order to experience weight loss through calorie consumption you will need to consume less calories that your daily required limit. For a woman to lose one pound of fat a week, she would need to consume no more than 1500 calories a day.
2000 daily calories x 7 days = 14 000 calories week
14000 - 3500 divided by 7 = 1500 (daily calorie intake required in order to lose 1 pound week)
Combined with exercise the amount of weight loss could be greater than one pound a week, but this will depend on the amount of calories are burned through exercise.
Weight loss and fat reduction
Fat reduction can have a positive effect on weight loss in Men have a daily fat limit of 90g fat, for women this is 70g fat. Saturated fat is stored in the body, particularly on the arteries, heart, increasing the risk of heart disease or a stroke, so daily limits for these type of fats are much lower.
In order to lose weight through fat reduction, consuming a low fat diet is ideal.
Achieving fat loss through dieting:
Dieting can effect weight loss dramatically. A reduction of calories consumption can cause weight loss and this is a typical requirement for effective dieting.
Fat reduction is also an aspect of dieting. A diet consisting of high levels of saturated fat will hinder any weight loss efforts.
Polyunsaturated fats are a type of healthy fat. They can be found in oily fish, nuts, Olive oil and Sunflower oil to name a few. High levels of saturated fats are in unhealthy foods such as crisps, cakes, chocolate, pastries and cream, so avoid unhealthy foods if you want to lose weight by decreasing your fat intake.
Weight loss and a healthy metabolism
Your metabolism is the rate at which your body burns food for energy (KJ). Having a high metabolism means you will burn up calories quicker, particularly during exercise. A low metabolism will have the opposite effect, so if you consumer more calories and your body still hasn't used up the previous calories then it may have a disastrous effect on your weight loss efforts. Foods that are known to increase your metabolism are, sea kelp
Achieving fat loss through exercise
Exercising can be beneficial towards losing weight. Exercising causes the body to use specific muscles and raises your body temperature, causing the body to burn up calories to give the body the energy it needs to carry out that function. Exercising can also speed up your metabolism so when your body is resting it is still burning calories. This is said to be up to half an hour after rigorous exercise.
It is best to include cardiovascular exercises in your routine. These are exercises that will help you have a healthy heart, running, jogging, walking and cycling are the popular options.
Try to exercise for a minimum of three times a week for at least 30 minutes each time. Even walking is a good option and many people have lost weight from walking for 30 minutes a day, combined with a low calorie or low fat diet.
Unintentional weight loss
Sometimes weight loss can be a result of a disease. The most common diseases that inflict weight loss are AIDS and cancer.
