Effectiveness of Smartphone Application for Weight Loss

It is the estimation of weight without wearing extra things by the individual. Excess or reduced weight is viewed as a sign of deciding an individual's health, with body volume estimation giving an additional aspect by calculating the distribution of body weight. A weight machine is usually used for this purpose. Weight machine is a gadget used to measure weight or mass, which is also called weight scale and weight balance system. The conventional scale comprises of two plates suspended at equal distances from a fulcrum. However, in this study, a digital weight machine will be used. The hardware comprises of a load cell or a weighing scale. The load cell calculates the person's weight and turns the mechanical force into electrical signals that can be easily obtained after microcontroller processing. Excess or reduced weight is viewed as a sign of deciding an individual's health, with body volume estimation giving an additional aspect by calculating the distribution of body

BMI stands for Body Mass Index. Mathematically it is calculated as, an individual's weight in kilograms (or pounds) divided by the square of level in meters (or feet). The categories of BMI are as follows: < 18.5 as underweight, 18.5 < 25 as normal weight, BMI 25 < 30 as overweight, BMI 30 < 35 as low obesity, BMI 35 < 40 as medium obesity and BMI ≥ 40 as extreme obesity

Blood pressure is the force of blood pushing against the walls of arteries. Each time heart beats, it siphons blood into the supply routes. Blood pressure is highest when heart beats, pumping the blood. This is called systolic pressure. At the point when heart is very still, between beats, blood pressure falls. This is called diastolic pressure. Sphygmomanometer is used to measure blood pressure. It typically consists of an inflatable rubber cuff which is applied to the arm and connected to a column of mercury next to a graduated scale, enabling the determination of systolic and diastolic blood pressure by increasing and gradually releasing the pressure in the cuff. Normal blood pressure is considered as 120/80 mmHg as systolic/diastolic pressure.

It is the highest rate of oxygen consumption attainable during maximal exercise
