Can protein be used for energy by the body?
proteins can be used for energy .The amino group is stripped off ( oxidative deamination ) and transferrred to an acceptor.The deaminated amino acid is now a keto acid that is a carbon skeleton. Of the 20 common amino acids 14 of them give a carbon skeleton that cab be used to make glucose .....4 of the others make one fragment for glucose and one fragment for fat. ( acetyl CoA or acetoacetyl CoA ). Only two common amino acids produce carbon skeletons that produce only acetyl or acetoacetyl CoA viz., leucine and lysine. The liver is quite able to o make GLUCOSE for blood glucose and tissue energy from the amino acid alanine ( from muscle )which is deaminated to pyruvate..and thence to glucose. Since one must have carbohydrate or a precursor of carbohydrate to burn fat...when carbs are low ( such as in Adkin's dieet ) then protein/amino acids will supply the carb skeletons to burn fats . Even chain fatty acids cannot produce any glucose .
When you exercise, does your body burn off the last thing you ate or the most fattening thing you ate first?
Your body burns off the most readily available energy first. If you want to compare chocolate and a sandwich, you first need to look at what they are composed of. Chocolate, of course, is mostly simple sugars. Sugars are extremely easy for the body to convert into energy, so almost as soon as you eat it, the energy is ready to be used. (That's how you can get a sugar high.) A sandwich however is going to be composed complex carbohydrates (bread) and some fat and protein (meat.) Both of these take a while to be broken down into the components that the body uses for energy. So, consider your first situation. Once you eat the chocolate bar, the calories are either used right away, or stored in the body. Later, when you eat the sandwich, and immediately go on the run, your body hasn't had the chance to break down the energy in the sandwich into usable forms, so the energy you use will be from energy stored in your body (i.e. the chocolate bar.) **Note that this only works if you run immediately after eating the sandwich. In the second situation, you ate the sandwich, and over time, the carbohydrates and proteins are broken down and used as energy. Then you eat the chocolate bar, and immediately go on a run. In this case, you are probably using energy from both. The sandwich because it is still providing energy as it is slowly digested, and the chocolate because those sugars are ready right away. Regardless, a calorie is a calorie no matter where it comes from. Chocolate, bread, meat, it doesn't matter because it will all turn into fat if you don't exercise.
Getting rid of negative energy?
I have this horrible feeling that for a long time now i've got some type of negative energy/spirit... something attached to me and that's why i'm in such a funk. I don't even know if i believe in such things but i'm beginning to...what can i do?
Is there such thing as permanent fat storage in your body?
um actually if u drink the alcohol is the first thing that is burned off so say u drink and u have 200cals in beer and like 400cals in buffalo wings (just and example)rite...well if u burn 400cals, 200cals from the buffalo wings will be stored as fat..but if u burn say 600cals nothing will be stored as fat..alcohol like anything else is a calorie the only difference is that it's burned off before your other calories in ur body stored up for energy so no its not Permanat fat storage just tougher to get off..
Does your body burn visceral fat at the same rate as subcutaneous fat or is one preferred over the other?
Hey! I actually just answered a question like this the other day, so I'm gonna borrow a lot from that one...Your body doesn't select where it adds to or takes from. You don't have any control over this - you just have to reduce overall levels until it starts to impact your visceral fat.There are a couple of things you need to do if you want to reduce fat.Most importantly, you have to create an energy deficit. The easiest way to do that is with mild calorie restriction and an increased level of exercise.I don't know what you're doing currently, but there are a number of ways you can accomplish this. They're the topic of another answer, but I'd be happy to include them if you like. - Start exercising if you haven't already. Focus on things that burn a lot of energy once you've created the proper base of muscle and aerobic fitness for yourself: High intensity interval training, weight lifting, and swimming are all great ways to burn energy.*There are a ton of other benefits to this beyond just losing weight - you'll feel better, have more energy, and be generally healthier.**If you find it enjoyable, I would definitely recommend swimming. Not only is it low-impact, it can be a lot of fun, and it's incredibly energy intensive. You burn a ton of energy.- Lean muscle will burn more energy every day than fat - as you build muscle and get stronger, your expenditure with actually go up.Weight training can also be specifically beneficial in reducing fat.In a study published in April, 2014 in the Journal of Sports Sciences. Researchers found that aerobic training combined with resistance training was much more effective at improving the levels of visceral and subcutaneous fat, compared to those who did just aerobic training alone.Anyway, all of this to say that a proper diet, combined with the right exercises (and possibly weight lifting), will help you reduce both visceral and subcutaneous fat.
Why do some things burn faster than others?
It depends on many factors. The amount of surface is a big one but it relates to size and shape. If you hold size and shape and surface area constant and you hold the source of ignition constant, then it gets down to the chemical reaction. Different materials produce different amounts of heat when they react with, for example, oxygen. If you react 1 kg of Al to Al2O3, it releases 7 times more energy than a kg of dynamite exploding. So, different compositions of paper will generate different amounts of energy when burned. If the paper contains some that releases more energy, say wax or gasoline, it will burn faster than paper that does not have these "fuels".
How far, in miles, would the person have to walk to burn off a pound of body fat?
On a brisk walk, a person burns about 325 Cal/h. If the brisk walk were done at 4.0 mi/h, how far, in miles, would the person have to walk to burn off a pound of body fat? (A pound of body fat stores an amount of chemical energy equivalent to 3500 Cal.)
