Can Einstein's mass - energy equivalence be related to losing weight?

Question

Well, if you think about it, everytime you exercise, you use energy which results in a loss of mass!

Answer 1

No, these two are different. When we exercise and we lose mass, we are converting fat into energy (hopefully and not losing water or muscle mass). This is a chemical reaction just as carbon burns in air to give carbon dioxide and also gives off some energy. 1 gram of fat is equal to about 8 to 9 Cals.

Einsteins's equation refers to the equivalence of mass and energy in nuclear reactions of fission and fusion. Nuclear reactors and sun are examples of this type of energy. 1 gram of uranium gives energy equal to about 2.5 tons of coal!

If we try to lose weight based on that equation, we will not lose even a kg in our whole life time!

Answer 2

E=MC^2
Mass-energy equivalence proposes that when a body has a mass, it has a certain energy equivalence, even "at rest". This is opposed to Newtonian mechanics, in which a massive body at rest has no kinetic energy, and may or may not have other (relatively small) amounts of internal stored energy (such as chemical energy or thermal energy), in addition to any potential energy it may have from its position in a field of force. Thus in relativity theory, a body's rest mass is often called the rest energy of the body. The E of the formula can be seen as the total energy of the body, which is proportional to the mass of the body.

Even a single photon traveling in empty space can be considered to have an effective mass, m, according to the mass-energy equivalence formula. A photon never can be measured at "rest", but the formula above applies not only to single particles when they are at rest, but also to systems at rest (i.e., systems when seen from their center of mass frame). Individual photons are nerverless often considered to be "massless", (i.e., they have no rest mass or invariant mass) even though they have varying amounts of energy and relativistic mass. But, systems of two or more photons moving in different directions (as for example from an electron-positron annihilation) may not have a momentum. Their energy E may be interpreted as an invariant mass m = E/c2, applying the mass-energy equivalence formula to them as a system.

This formula also gives the quantitative relation of the quantity of mass lost from a resting body or a resting system (a system with no net momentum, where invariant mass and relativistic mass are equal), when energy is removed from it, such as in a chemical or a nuclear reaction where heat and light are removed. Then this E could be seen as the energy released or removed, corresponding with a certain amount of relativistic or invariant mass m which is lost, and which corresponds with the removed heat or light. In those cases, the energy released and removed is equal in quantity to the mass lost, times the speed of light squared. Similarly, when energy of any kind is added to a resting body, the increase in the resting mass of the body will be the energy added, divided by the speed of light squared.

Answer 3

If you loose 1 kg then you will be releasing 89875517873681764 KJ energy and thats toooooooooo much of energy ;-)

By the way its chemical energy released by burning glucose which we get from our food.

Answer 4

Sorry the God haters were speculating theories that disproof God and the more beneficial information in technology we study the more beneficial the information factors to a wise clothier and the Holy Bible has adequate information in one of those vast quantity of elements which proofs it to be the words of our author , you adult men hate the actual shown actuality that their is 0 information on your claims and no you'll disprove something written contained in the Holy Bible

Answer 5

No. It's chemical energy, not mass-energy ☺
