How do you calculate energy content?
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). where H = heat energy absorbed (in J), ∆t = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water).

Can I lose weight 1800 calories a day?
For example, researchers reviewed data from six trials of very-low-calorie diets (fewer than 800 calories a day) and found that, after about 26 weeks, participants lost 16 percent of their initial body weight, whereas participants on a typical low-calorie diet (1,000 to 1,800 calories a day) lost about 10 percent of …
What is calorie output?
Caloric intake is the number of calories you eat and drink each day, and caloric output is your resting metabolic rate plus any physical activity expenditure. If caloric intake exceeds caloric output, then the excess calories are deposited as fat in your body, and body weight increases.
Can you lose weight by eating 1600 calories a day?
If you reduce 1000 calories in a day, by the end of the week you should have lost around 2 pounds. If you are a person who usually consumes 2100 calories and above in a day, consuming 1600 calories which is a 500 calorie deficit from your normal intake will promote weight loss (5).

The amount of calories burned increases according to body weight. So, a person who weighs 150 pounds might burn 46 calories an hour or between 322 and 414 calories a night.
What is the formula of energy?
The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.
Is 1000 calories a day healthy?
On the other hand, decreasing your calorie intake too much can be counterproductive. Studies on very low-calorie diets providing less than 1,000 calories per day show they can lead to muscle loss and significantly slow down metabolism (5, 6, 7).
