Weight loss is not an easy task whether you try to lose 5 pounds or 50 it need efforts. And obviously unlimited efforts. Our body weight is determined by the amount of energy we utilized daily, energy in our body is measured in calories whenever you notice same weight it means you are taking same amount of energy daily ,if you are gaining weight slowly it means you are taking calories that are slightly higher than your work. One thing that I in control is the amount of calories we are taking daily and to a major degree we can also control our energy output .lifestyle and our work habits determine how many calories we take or burn daily.
Someone whose job involves heavy physical labor will naturally burn more calories in a day than someone who sits at a desk most of the day (a sedentary job). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.
For a healthy living one has to obtain a perfect chart of input calories daily!! Healthy lifestyle is directly proportional to your daily diet and food intakes.
