On one hand food routine is crucial but some physical activties are also a must. It should be a combination of both to achieve the desired effect.
To reduce body weight quickly one must eat low calorie food every day and have the sense of food control too.
By all means: Don’t skip breakfast! “Hunger and a feeling of deprivation get the best of you,” warns The New Teenage Body Book. “You’ll tend to load up on food—and calories—late in the day.” Also try to drink a large glass of water before each meal. This will fill your stomach. Drinking adequate amounts of water also appears to play a role in reducing body-fat deposits. Doctors therefore recommend drinking at least eight glasses of water a day. Don’t eat and watch TV. If you are busy watching TV you can begin eating like a machine. :)
It is also recommended to eat slowly. It takes about 20 minutes for the stomach to signal the brain that it is full. Eating slowly will thus help you to “eat to satisfaction,” but no more! Also find healthy alternatives to eating—especially if you have been in the habit of eating whenever you are bored, tense, lonely, or depressed. Talk to someone you trust. Go for a walk, or exercise. Work on a hobby. Listen to music. Eventually, those unwanted pounds will come off. Good health to you! :)
Losing weight is a simple equation: If you burn more calories than you eat, the weight will come off. Start off by estimating how many calories you burn each day using Weight Loss Calculator.This will give you an idea of how many calories to eat. Healthy weight loss is 1-2 pounds per week. To lose 1 pound per week you need to create a calorie deficit (burn more than you eat) of 500 calories per day. To lose 2 pounds a week, you have to double the deficit to 1000 calories per day. You can achieve this by eating less, exercising more or a combination of both.
Determine how many calories your body needs each day (the link below may help). Though without exercise it will be much more difficult, if you reduce calories, you can still lose weight. In lieu of typical exercise, you may be able to do workouts using only those body parts you can get away with moving. For example, even in a sitting position you can do punching exercises with your arms that will increase your heart rate. Just find things you can do that force you to move your body.
