Do we lose weight through exercise according to that equation? I mean fat is turned to heat during exercise right?
No. That equation gives was is termed the rest energy of a particle of mass m. Indeed fat and carbohydrates (and protein to come extent) are metabolised to provide energy for respiration the rate of which increases during exercise. We lose weight not because we convert mass into energy but when we excrete the metabolites. i.e when we break down carbohydrates we excrete the waste products. I am not a biologist so this is probably a rough and ready explanation but I can say without a doubt that when you exercise you do not convert mass into energy. In fact, immediately after exercise probably all of the weight lost is due to water loss (sweating, ventilation etc.)mtanti said:Do we lose weight through exercise according to that equation?

I believe most respiratory metabolites are excreted through urine. Look up respiration -Glycolysis, Krebs Cycle, Electron Transport chain to see what the metabolites are and perhaps you can see how they are excreted.mtanti said:So where does the metabolised material go? All through roughage?
No, we are not. That is why I said immediately after exercise.I mean we are not losing weight because of lost water as sweat in the long run since water is something we consume a lot of during a diet...
Thank you! Is it the same energy as referred to in e=mc2?Office_Shredder said:It's heat released from chemical reactions in our body. Which means yes, it starts as food and drink

Increases your rate of respiration, more carbohyrates metabolised producing more CO2 and water.mtanti said:Why does increasing your metabolism help?
I'd prefer it if we said the greater the rate of respiration the more energy we use. If we use more energy than we take in, then we will lose weight.mtanti said:So basically the more you breathe, the more weiight you lose?
Well, there's also sloughing of material such as hair and skin cells, but this is not dependent on metabolism, it's just a constant.mtanti said:Yes we all know that the weight we gain depends on the difference between energy input and output but the question is what happens to mass we lose... Does it turn to carbon dioxide, sweat and feaces only?
The equation E=mc^2, also known as the mass-energy equivalence equation, explains the relationship between mass and energy. In the context of weight loss through exercise, this means that the energy we expend during physical activity is equivalent to the mass (or weight) that we lose.
While exercise does contribute to weight loss, it is not the only factor. Our diet, genetics, and overall lifestyle also play important roles in maintaining a healthy weight.
The amount of exercise needed to lose weight varies for each individual, as it depends on factors such as current weight, metabolism, and intensity of the exercise. However, the general recommendation is to aim for at least 150 minutes of moderate to vigorous physical activity per week.
No, the equation E=mc^2 is a theoretical concept and cannot be used to accurately predict weight loss. Other factors, such as muscle gain, water weight, and individual body composition, also play a role in weight loss and cannot be accounted for in this equation.
Yes, weight loss through exercise is primarily a result of burning calories. When we engage in physical activity, our bodies use energy (calories) to fuel our movements. This leads to a calorie deficit, which in turn leads to weight loss. However, other factors such as muscle gain and changes in metabolism also contribute to weight loss through exercise.
