    The dietitian wasnt wrong but the average American diet has too much everything, thats why they lead the world in obesity.

    Theres 9 calories per gram of fat, 4 calories per gram of protein and carbs. On average, a person uses about 10% of their daily energy expenditure digesting and absorbing food, but this percentage changes depending on the type of food you eat.

    Protein takes the most energy to digest (20-30% of total calories in protein eaten go to digesting it). Next is carbohydrates (5-10%) and then fats (0-3%).

    Thus, if you eat 100 calories from protein, your body uses 20-30 of those calories to digest and absorb the protein. You’d be left with a net 70-80 calories. Pure carbohydrate would leave you with a net 90-95 calories, and fat would give you a net 97-100 calories.

    Im not going to diatribe at you, but I did a lot of deep diving into diet science and macronutrients over the past 2 years in regards to weight loss vs muscle gain diets and the best advice I can give you is to track your macros because once you establish “Im holding a steady weight at 2800 calories a day” then you can reduce that number by a reasonable figure like 10% and work out a sustainable diet. That bowl isnt sustainable, at best you will feel flat, unenergetic and start losing muscle mass. At worst you will throw it in the fuck-it-bucket and order a pizza.

      No, I completely agree with you; especially the breakdown of calories per gram of each macro. My professor told the class that protein cannot be burned like fat and carbohydrates. Excess protein that is not needed for muscle repair and growth, is excreted by your body, and can be exceptionally hard on your kidneys in large amounts. Your body will store extra carbs and fat, making those be stored as fat cells in the body. The extra protein can’t be stored. This is why she gave such lectures on how we don’t need large amounts of protein in our diets.

        Again, not wrong. Just reads like selective facts.

        Out of curiousity how much protein do you think you need and how tall are you?

        While the facts are correct, the interpretation isn’t.

        • Protein itself can’t be stored. That doesn’t mean that the excess is useless. They’re converted into glucose, which your body can use directly or store for later as fat or glycogen.
        • This process happens in the liver, so if you consume more protein, the liver does more work. The question you should be asking here is whether or not that’s a problem. And it isn’t, unless you already have liver problems to begin with.

        And while it’s true that the average person needs very little protein, there’s also a large distribution of protein needs even after normalizing for your size/sex, so you can’t prescribe a hard number based on this information alone.

          Your body turns carbohydrates into glucose first for energy. If carbohydrates aren’t readily available, then it utilizes fat in the diet. Your body does not turn to protein first, or even second. You would have to have most of your calories coming from protein and not be over on calorie count to make your body utilize protein.

            There’s no such prioritization on your body. Everything happens concurrently. It’s constantly turning glucose into fat and fat back into glucose. It’s constantly breaking down amino acids and reforming them. Different processes will just occur at different rates depending on the concentration of reactants and products. So going from amino acids to glucose happens a lot slower when you have other energy sources, but it still happens.

            I also don’t see how your comment supports your claim. Even if this prioritization takes place, the protein you consume still serves the purpose of being an energy source. That’s very different from being unable to burn amino acids for energy at all as you said earlier.

              I don’t know. All I know is that a couple of biology teachers and one dietitian have told me that the body converts carbohydrates to glucose first. I haven’t conducted any of my own experiments, but then again I believed my biology teachers about Punnet squares with regard to blood types of offspring, too. Ask my AB+ ex boyfriend where all of our non-existent children, prior to 2009, are.
