Carbohydrates are mainly sugars, and sugars are what the body needs to convert the food into energy (note: these carbohydrate "sugars" are not the same kinds of sugars found in candy bars and junk food, meaning you can't just eat junk food all the time to sustain your body's energy supply). <br><br>Fats are just used by the body as heat insulators, and also stored energy reserves. <br><br>When people put on weight, it is because they eat more food than the body needs, and the excess carbs are stored as energy reserves in the form of fat cells. The only way to get rid of the stored energy reserves, or fat cells, is to eat less and move around more. <br><br>People should be cautious when going on one of those "low carb diet" fads, however. It is not good to strictly limit your carb intake for long periods of time. The stored energy in fat cells is never as good as new energy coming into the body through carbs, so always eating some carbs is a good thing. If you're trying to lose weight, the best thing to do is eat HEALTHY carbohydrates (sweet potatoes, beans, whole wheat products), increase your protein intake (fish, chicken, meats - protein helps prevent your from becoming fatigued during exercise and also helps repair muscles, along with a host of other things), WORK OUT (lifting weights in combo with cardio), and DRINK LOTS OF WATER TO FLUSH OUT YOUR SYSTEM. <br><br>Tried and true. <br><p></p><p>
</p>You don't necessary need carbohydrates more than fats carbohydrates are just like calories except they give you energy faster and if you don't use them right away they turn into fat.
why do fats contain more calories then carbohydrates
When it comes to carbohydrates or fats producing more ATP, fats tend to produce more ATP per gram. Fats contain about 33 percent more ATP than carbs.
Fats are more reduced than carbohydrates, therefore there is more oxidation that occurs in the breakdown of fats, and hence, more energy is produced.
yes they are
Carbohydrates are the body's main source of energy and should be the major part of total daily intake. There are two types of carbohydrates: simple carbohydrates (such as sugar or honey) or complex carbohydrates
Fats provide a form of store energy. Fats can provide more than half the energy that the body needs and twice as much as than carbohydrates
Fats are a better source of energy than carbohydrates on a per carbon basis because fats contain more carbon-hydrogen bonds, which store more energy when broken down compared to the carbon-oxygen bonds in carbohydrates. This means that fats provide more energy per carbon atom when metabolized.
Fats actually contain a lot more energy than carbohydrates. The reason carbohydrates are used for energy before fats is because carbohydrates are easier to break down; reactions involving carbohydrates generally have a lower activation energy. This means that less energy is used to release the energy in the bonds of the carbohydrates than fats. In other words, although fats contain more energy, it is more efficient for the body to break down carbohydrates than fats. Once carbohydrate supplies diminish, fat stores can be broken down to use for energy, but doing so is not the body's favorite thing to do.
Fats have more energy because they contain more carbon-hydrogen bonds, which store more energy than the oxygen-hydrogen bonds found in carbohydrates and proteins. When these bonds are broken during metabolism, fats release more energy in the form of ATP, making them a more efficient energy source.
Carbohydrates are preferred over fats for providing quick energy because they can be broken down and converted into energy more rapidly than fats. This is because carbohydrates are more easily and quickly metabolized by the body, making them a quicker source of energy for immediate use.
fats are more complex than other forms of carbohydrates so it take more energy for the body to break them down, so generally if it doesn't need to it doesn't break them down if your body needs the energy it will break down the fats
fats and proteins
