Why do fats have about 9 calories per gram and carbs have 4 calories per gram?
I think it is for the same reason that the sky is Blue, there is a huge scientific reason that will not affect anything we have control over…But, it brings up a Great Point.My journey started while studying Anti-aging, all data points to lowering your caloric intake. No matter what the end goal is though, weight loss, wellness, or anti-aging, everyone agrees that less calories per day is the way to go.Well great!! more hunger pains I thought, but learning that fats contained twice the calories, I would have to eat less, but why?Turns out that fat is the primary fuel for our body, mind and gut, not carbs. Fat keeps insulin low, and that causes better use of the fat we eat, and the bodies fat stores, so this actually gives us more energy between meals, and stops the cravings.I was not trying to lose weight, so I stayed on my 2000 calorie diet, and even up it to 2200 calories per day. Problem was I couldn’t consume even 2000 calories each day because I wasn’t hungry, at all. I keep my carbs well below 70 grams and ate no fruit or veggies, and my Body Fat Dropped to 15%.So what’s all that mean? At 63 years old this summer, I lost body fat, have way more energy, and all my joint pain and IBS went away. Plus I eat less Calories per day, just as directed for anti-aging, not bad.To me carbs are like e85 gasoline, and fat is like Jet Fuel. That’s the difference, and probably the reason as well. If our bodies had a Sticker where we add Fuel, like on our vehicles, it would say, High Fat Only.
How many calories are there per gram of body fat?
It is sadly in no way as simple as reducing your calories by a number to burn a number of fat calories. Lyle McDonald explains it well below.The mathematics of dietingWhen people try to set up weight or fat loss diets, they tend to doit based on fairly simple math. The typical approach is this: first they set a 500 calorie per day deficit and multiply that by 7 to get 3,500 calories. Well, 3,500 calories is one pound (kind of, as above 3,500 calories is only for one pound of fat and represents 5 lbs of muscle) so they should lose exactly 1 pound per week. And it basically never happens.7 Usually they lose faster than predicted initially and then more slowly than predicted after that. But it's basically never as the math would predict it to be. At least some of this is due to the differences in tissue composition of what is being lost.8 There is an early loss of water and glycogen (moreso on a low-carbohydrate diet) that is far faster than predicted since water contains no calories and glycogen contains far less than 3,500 calories per pound. This is primarily what led to the erroneous idea that low-carb diets have a metabolic advantage.9 After that, some proportion of fat and LBM will be lost and the percentage of each will determine the calorie value of every pound lost. Only when 100% fat is being lost (and this can and does occur) will a 3,500 calorie deficit per week yield exactly one pound per week weight loss.But even when that supposed 500 cal/day deficit is set up and the body is losing 100% fat, the real-world fat loss is never the same as the predicted fat loss, it's basically always lower. There are many possible causes of this including simply not-adhering to the diet, mis-tracking food intake or water retention but I'm going to assume that none of those are occurring here. Rather, and here I'm finally getting to the point of this article, is the fact that the body adapts to dieting and fat loss in a way that slows fat loss.
How many grams of protein, carbs, and fats per day?
This is a GREAT site for calculating your macros and basically all you need. http://forum.bodybuilding.com/showthread... It's a lot to read, but very useful. Normally, one would have an intake 100-250 calories above their maintenance when trying to gain muscle mass so that it's not too little to not gain, and not too much to gain fat. I'm not sure that you can lose fat and build muscle at the same time since one is anabolic and the other is catabolic and your body can only be in one state. So you can try focusing on losing body fat right now where you'd basically eat and train like you would if you wanted to gain muscle, but with a calorie deficit, and once you're happy with you're weight, go gain. Or, you can build some muscle now and go on a cut later. Since Insanity is cardio, if you plan on continuing that while gaining muscle, you'd have to weight train at least 3 times a week as well.
How many grams of carbs should we eat after a workout?
Depends on your gender and weight. Typically women need slightly less than men. Also you need to consider the intensity and duration of the workout. Basic 30 min speed walk would be different then if you did a 1 hour powerlifting routine.There's always controversy with these types of questions. The important thing to remember is that carbs are your body's first go-to resource for fuel during your workout. Then protien and lastly fat. There are too many factors that determine what is right for your personal digestive & metabolic needs. You have to consider this equation:For Carbs, Protien, & Fats:Daily needsPre-workout needsDuring workout needsPost-workout needsAfter all of that is calculated then from you "Daily" needs you'll know how much you need for the rest of your day.For a simple answer that you can use now:Take your weight - 60% = Carbs50% = Protien20% = FatMeaning for example you weigh 100 lbs.100 - 60% = 40 carbs etc..Goodluck!
How do you convert grams of carbonhydrates, proteins, and fats to percentages to go on a pie graph?
Assuming you're asking how to convert grams of carbohydrates, proteins, and fats to the percentage of calories you have taken in, I don't think Drum's method will work. The reason why is carbohydrates contain 4 calories per gram. Protein contains 4 calories per gram. Fat contains 9 calories per gram. That means per gram, fat contains over twice as many calories as carbs and proteins, so let's say you do it his way and multiply straight out. 100 grams of carbohydrates, 100 grams of protein, 100 grams of fat. Doing it his way, you'd divide the pie chart up into thirds. One-third of your calories from carbohydrates, one third from protein, one third from fat. The trouble is, if you consume 100 grams of each, you have taken in 400 carbohydrate calories, 400 protein calories, and 900 fat calories, for a total of 1700 calories. Divided out, that means only about 23.5% of your calories have come from carbohydrates, 23.5% have come from protein, and 53% of your calories have come from fat. So how do you figure out what percentage of your calories come from each source? Multiply the grams of carbohydrates by 4. Multiply the grams of protein by 4. Multiply the grams of fat by 9. Take all three numbers, and add them together. Then, divide the calories from each individual nutrient by the total number of calories to get a decimal value. Added together, all three decimal values should equal approximately 1. For instance, take the 100 gram example I gave you above. 100 grams carbohydrates. 100 x 4 = 400 100 grams protein. 100 x 4 = 400 100 grams fat. 100 x 9 = 900 400 + 400 + 900 = 1700 Carbs: 400 / 1700 = 0.23529... (rounded off, 0.235) Protein: 400 / 1700 = 0.23529... (rounded off, 0.235) Fat: 900 / 1700 = 0.5294... (rounded off, 0.53) 0.235 + 0.235 + 0.53 = 1.00 Now all you have to do to convert to percentages is multiply each decimal value by 100 (just scoot the decimal point two spaces over to the right, so 0.235 becomes 23.5 and 0.53 becomes 53). That's how you do it.
Calories,carbs,fats..!?
foods are made up of carbs, fats and proteins, they are called macro nutritents and are the main 'building blocks' of food. Generally in 1 g of carbs = 4 calories, same with protein. In 1g of fat = 9 calories. It depends whats in the food how many grams of each there are. Food doesn't have to include all 3, although most do. 3,500 calories =1 pound. Most people burn on average 1,500 calories/day. So 10 calories is nothing compare to that. There is a lot to your answer, so I hope this helps a little bit.
How many calories are in 35 grams of fat?
1 Gram of fat contains 9 kcal, meaning that 35 grams of fat will contain 315 calories. Fat is the most calorific macro out there, because carbs and protein only contain 4 kcal per gram. But this doesn’t mean that you should cut out all the fat in your diet to save calories! Your body needs every macro nutrient because they all have different roles in your body. Carbs are your main energy source, protein is the building block and fats make sure your hormone system is in balance.If you’d like to learn more about the different macro nutrients, this link will help you out: Macros 101 : Part 1
Is 50-100 grams of carbs per day good for steady weight loss?
If you typically eat over 100g of carbohydrates per day you should notice a weight loss by reducing this to 100g and even more if you reduce it to 50g.The amount of carbohydrates you consume (if trying to lose weight and get into ketosis) is directly related to your current weight.You must first figure out how many calories you need each day and then break down your percentages of macronutrients (carbs, protein, and fat).Example:Weight: 200Normal Diet: 2000 caloriesActivity: SedentaryDesired weight loss: 1lb per weekFirst, you figure out your BMR - how much you need to eat to liveBMR = 200 * 10 = 2000 - this is how many calories your body needs for normal daily functions like breathing.Then you figure out your TEF - Thermal Effect of Food2000 calories * .10 = 200Next, you figure out your TEA - Thermal Effect of ActivityBMR * Activity Level = X - BMR2000 * 1.2 = 2400–2000 = 400Then you figure out your TDEE- Total Daily Energy ExpenditureBMR+TEF+TEA2000+200+400 = 2600 calories.This is what you need to maintain your current weight.If your aim is to lose weight then you need to find your weekly calories and minus 3500 calories (1lb of fat).2600 * 7 = 18,20018,200 - 3500 = 14,700/7 = 2100 calories (calories for weight loss)Then to figure out your macros.Fat = 70%2100*.70=1470/9 (cal per g fat) = 163.33g of Fat should be consumed.Protein = 25%2100 * .25 = 525/4 (cal per g of protein) = 131.25g of Protein should be consumed.Carbs = 5%2100 * .05 = 105/4 (cal per g of carb) = 26.25g of carbohydrates should be consumed.So if you weigh 200lbs and your goal is to reach ketosis you should consume only 26.25g of carbohydrates per day.
How do I figure out what 960 calories of carbs is in grams?
Well I need 3200 calories daily to build muscle and 30% of those calories has to be carbs. So I need a total of 960 calories coming from carbs alone. How do I figure out what the 960 calories coming from carbs is in grams? To ask it in a different way, how much grams of carbs do I need daily with this diet?
Calories in grams....??
1 gram of carbohydrate = 4 calories 1 gram of protein = 4 calories 1 gram of fat = 9 calories 1 gram of alcohol = 7 calories It depends on what is in that gram. ^^^ then you use _grams carbohydrates x 4calories/gram = 36 calories Or use this, http://www.freedieting.com/tools/nutrien... it's easier
