Weight losss.... gyaan ...

To successfully lose weight, you must carry out a plan to balance your caloric intake with exercise.
Ideally, dieting should be done by eating a nutritionally balanced, low-calorie diet and increasing physical activity.

Weight loss occurs when an individual is in a state of negative energy balance. When the human body is spending more energy in work and heat than it is gaining from food or other nutritional supplements, it will use stored reserves of fat or muscle.

Although weight loss may involve loss of fat, muscle or fluid, weight loss for the purposes of maintaining health should aim to lose fat while conserving muscle and fluid


Although there are many programs advertised to help you lose weight, the only proven long-term and safe method is to burn more calories than you consume.

This is achieved either by reducing the caloric intake (eat less food or healthier food) or by increasing the energy expenditure (exercise more). Often, behavior modification techniques like eating smaller portions are used to help control eating habits. Once the weight is lost, these habits can be modified slightly for weight maintenance.

WEIGHT LOSS TIPS

One pound of fat contains approximately 3,500 calories, so to lose one pound a week, a person should consume approximately 3,500 fewer calories per week. This can be done by reducing the daily intake by 500 calories per day (500 x 7 days will provide a deficit of 3,500 calories per week). To lose 2 pounds per week, a deficit of 1,000 calories per day is required.

If this seems impossible, remember that physical activity also contributes significantly to weight loss. The deficit of 500 to 1,000 calories can come from a combination of increased physical activity and reduced intake on a daily basis.

Therefore, you don't need to experience significant food deprivation. The lowest intake per day recommended for women is 1,200 calories, unless they are in a medically-supervised, very low-calorie regimen which may have a daily level of 500 to 800 calories per day.

The lowest level recommended for men is 1,500 calories per day. A very low-calorie diet can also be used by males if they are in a medically-supervised program.

Tips for preventing weight gain:

Avoid foods that are high in fat and sugar.
Reduce how much alcohol you drink.
Avoid stress, frustration, and boredom.
If you are depressed, seek medical treatment.
Avoid a sedentary lifestyle by increasing your activity level:

Perform aerobic exercise for at least 30 minutes a day, 3 times a week .
Increase physical activity by walking rather than driving.
Climb stairs rather than using an elevator or escalator.

What are Calories:

Calories are the basic unit of energy within food. When you eat, your body converts calories into energy and uses what it can and stores the rest in the form of fat. A calorie is a calorie, whether it comes from a brownie or a serving of raw broccoli. The difference between them is the number of calories, nutrients, fat, and other ingredients in a typical serving.

Food Serving size Calories Fat (grams)
Broccoli 1/2 cup 12 0.2
Brownie 1 square 160 3




Successfully burning body fat requires numerous factors, one of the most important is the fitness level of the individual. With less fit people the Cardiovascular system is often not strong enough to deliver sufficient levels of oxygen to the working muscles in order to keep burning fat (fat requires oxygen to burn).
