Why are carbohydrates the main source of energy in our body instead of lipids?
Carbohydrates are the main source of energy in our body, but its energy value is less than half of that of lipids. (Each gram of carbohydrate provides 17.1 kJ of energy, and each gram of lipid provides 38.9 kJ of energy). So why aren't lipids used as the main source of energy in our body instead?
What is the body's main source of fuel...carbohydrates or fat?
Contrary to the answers above, the body actually uses fat as its main source of fuel at rest. This is because fat is able to provide a lot more energy than carbohydrates. In fact, low intensity exercises such as walking use mostly fat as fuel. Carbohydrates are reserved for the brain as it only wants to use carbohydrates as fuel. The rest of the carbohydrates would be stored in your blood and liver for quick or high intensity movements. The only reason why we don't seem to lose the fat while sitting down doing nothing is because insufficient calories are burnt and when we eat, the excess sugar from carbohydrates will be stored as fat if the body does not utilise it.
Can anyone list good source of carbs food?
6Sweet PotatoesThe intense orange color of sweet potatoes is part of what makes these tubers so healthy. They're chock-full of beta carotene, the precursor to vitamin A, which is essential for vision and a healthy immune system. You can drink your daily dose of sweet potatoes in this.LegumesLentils and beans contain complex carbohydrates, as well as fiber and protein. These qualities make it a food that fills you up.MilkMilk and other dairy products, like yogurt and cottage cheese, contain lactose — a type of sugar. Milk also delivers protein and sodium; the combination of these three components makes it a good beverage after intense workouts, according to research.FruitFruit is the best way to satisfy your sweet tooth. Fruit gets its sweetness from fructose, which is balanced with fiber, water, phytochemicals, vitamins and minerals. While low-carb diets tend to shun sweeter fruits, like bananas and mangoes, these are actually a great source of quick energy.PopcornPopcorn is actually a whole grain and it's high in antioxidants. Since the kernels pop up so big, you get 3 1/2 cups in a 1-ounce serving (if you air pop it, that clocks in at 110 calories and 4 grams of fiber).PotatoesPotatoes are an excellent source of vitamin C and potassium and offer several other necessary nutrients, as well as a good dose of fiber — 4 grams in a medium potato. Although potatoes have a high glycemic index, it's rare that you eat them solo; mashing them with milk, topping with cheese and eating the fiber-rich skin takes that glycemic index down, keeping your blood sugar from spiking.Whole GrainsTwo sources you're probably familiar with are 100-percent whole grain pasta and bread, but explore other truly unprocessed grains — like rye, farro, oats and quinoa — for added health benefits. Each grain offers a slightly different profile: quinoa delivers "complete" protein, while oats are a great way to get cholesterol-lowering soluble fiber.
What is the best protein, carbs and fat sources for bodybuilding while on a budget?
Technically organic sources will always be the healthiest options, though not the best sources for bulking on a budget. If you're okay with that, read on. I read an article on Bodybuilding .com titled: "Bulking on a Budget", verbatim. According to the author, he recommends brown or white rice and loads of beef for bulking on a budget. Both are extremely cheap, especially compared to, say, steak or shrimp; and both offer protein, fats and carbs; with an emphasis on the 2 most important macronutrients required for bulking: protein and carbs. With an even further progression towards cost effective, though a decline in health; I know Kali Muscle recommends dollar store cookies, top ramen, chips, cakes, pies and loads and loads of canned tuna. All of these foods contain high glycemic carbs and protein. (In case you're wondering, he most likely is on steroids, though it's never been proven. Lance Armstrong however was proven to be on steroids after a failed drug test. And he's tiny. So keep in mind steroids can help you get big, but a simple injection once a week won't do anything for you. You still have to get in those macros, train type IIB muscle fibers, sleep 8+ hours a night, supplement correctly, etc...)Be careful not to go overboard though. Hard gainers might need 3, 4 or even 5k+ calories a day to build muscle. But memsomorphs and endomorphs don't need so much. I know a good bulking phase for me is only 2,800 calories. Whereas some hard gainers can actually lose weight with that much, or more. Experimentation is definitely needed. Calorie counting is tricky. I'd recommend getting your body fat taken once a month. If it ever goes over 12%, you're bulking too quickly and gaining too much fat. Lower your calories by 400 per day and try again for another 2 weeks before getting another test done. Good luck with your bulk
Which food has the best energy source, marshmallow or popcorn?
Food energy is measured in calories. I'm assuming you burned the item and measured the temperature difference in water that was in a beaker above the flame, that's exactly how calories are calculated for food. I'm surprised the popcorn had more calories than marshmallows, I'm betting you had a fair amount more popcorn than you had marshmallows by weight but I could be wrong. (I'm also surprised how many of your answerers don't know SUGAR IS A CARB! In fact, it's the most pure form of carbohydrate, more so than starch, more on that later. So, both are carbs.) Popcorn and marshmallows store energy in the same way, carbohydrates. But, they're stored slightly differently. Popcorn is starch. Starch is made out of polysaccharides. Polysaccharides are comprised of several glucose molecules combined, while marshmallows are made of mostly, regular old sugar molecules called simple sugars, made of only one glucose molecule. Simple sugars are easier for the body to digest and they release their energy more quickly than polysaccharides that have to be broken down to be turned into energy. These are all reasons why I'd expect the marshmallow to have more energy, but, it looks like your findings have shown otherwise. That makes me think there's something else going on. Was it just more popcorn by weight? Was it candy coated popcorn, like caramel corn? Were the marshmallows not normal marshmallows, like sugar free sweetened with an artificial sweetener? Those are my best guesses, good luck.
Are blueberry muffins a good source for carbohydrates?
I am doing a project and I want too use blueberry muffins as an example of carbohydrates. If they aren't a good source, what other small, yummy foods with carbs are their? Not like pasta, because I don't want to bring that into my class. But like yummy little foods like muffins are(: Thanks
Want to know why CARBS are the DEVIL!!?
I am 25 y/o, 5'4 and weigh 173lbs.!!!! I have started my own variation of the Atkins diet (bcuz I don't have the book) I only eat lean meats, low-carb veggies/snacks as well as cheese and sugar free drinks/jellos. I've only been doing this for about 2 weeks, with a few slip ups here and there. My question is---I have read atleast 50 different resolved questions on here about how bad low-carb is, and how you need them to be healthy---yet the REASON I have been overweight ALL my life is because of my unhealthy addiction to pies, cakes, breads, pizza, fried chicken, loaded potatoes, french fries, rice, pasta galore, cupcakes, and every other BAD processed---white carb out there. And I HATE HATE HATE---when people say eat wheat bread, or brown rice---bcuz when you have an addiction to these bad carbs---ANY type of similar carb (disguised in color) still can TRIGGER you to eat bad carbs. So my question is---with my new diet (lifestyle change) I am following am I going to lose weight??!!
Is rice a bad carbohydrate?
It depends on what rice you eat and how much of it you eat per serving.White rice is devoid of most of its supportive nutrients. White rice is milled, which removes the bran, the germ and the husk. This is where you get your fibre, your minerals and your vitamins from.The telltale sign is its colour. Its white because it has lost its essence. Its the same story with bread and other white flour products. White bread has been milled, has lost its colour and its nutrients. Brown bread is WHOLE. Whole grain means it still packs the supportive nutrients it was meant to have.Brown rice is the unrefined, whole version of white rice. It has plentiful fibre, an abundant essential amino acid profile (proteins). Although not a ‘complete’ source of protein it can, and commonly is combined with beans and legumes to supply the full array of essential amino acid building blocks to build and maintain muscle cells, nerve cells, neurotransmitters for mood and energy, bones etc.Brown rice is plentiful in important vitamins and minerals such as Magnesium, B6, Iron and fibre. Magnesium and B6 are cofactors to neurotransmitter synthesis for cognition and focus as well as being important for the synthesis of the bodies energy currency ATP, made in our bodies cells. Iron is also a key player in energy synthesis, providing the transport network in red blood cells for oxygen to be used to create energy from our food.Doesn't sound so bad so far, right?One of the biggest points to take away from this is that white rice has little fibre, whereas brown has loads. This is important because it affects the way the sugar is absorbed and stored by your fat storage hormone, Insulin.Little fibre means rapid absorption of sugar causing blood sugar spikes, and consequentially energy lows afterwards. Energy lows lead to quick fixes which again tend to be sugar to get the blood sugar back up and energy back - its a viscous cycle and the same cycle that leads to fat storage in the unlucky ones.You also want to be aware of the glycemic load, that is the amount of carbohydrate that you eat. Eat until you are 80% full. Its easy to do with brown rice as fibre is filling and helps the uptake of other nutrients in the rice to keep you satiated and satisfied.How carbohydrates affect blood sugar
