True or False? A Calorie is a Calorie is a Calorie.

My nephew and his wife follow Paleo religiously. He says that calories from different sources behave differently in the body. I always thought that too. I was taught in nursing school that the body converts carbs to glycogen and in turn glucose, and it's readily absorbed into the bloodstream. Much glucose is absorbed by brain as it has no capacity to store fuel and needs a continuous supply. Only when there is an excess of glucose will it be stored as fat. On the other hand, fat calories are stored in the adipose (fat cells) cells to be used when needed.

So it begs the question, is excess sugar calories better than excess fat calories? Or does the end result make no difference? I'm only asking because I wondered if there is less risk if I blow the diet and eat a candy bar instead of an extra slice of pizza. Not that I'm planning to do either one. It's just something I'm curious about. I'm pretty new to MFP, so I apologise if this is redundant and has already been posted somewhere. Anyone have thoughts?

    I think a lot of studies suggest that sugar is worse, hence the success of low carb diets. Although I have read recent studies suggest that in the long run low fat vs low carb are about equally effective. I think everyone's body reacts differently and you don't know until you try. For me, if the calories are approximately equal I will gain weight from the candy bar. The pizza won't affect me as much.

    Yes, a calorie is a calorie. Too many calories from any source (carbs, fat, or protein) will be stored as fat. The grams of fat in your food are not automatically stored as fat.

    Excess calories of one macro are not better than excess calories of another macro. Excess calories cause weight gain.

    A calorie is a calorie. Just like a foot is a foot, a yard is a yard and a liter is a liter. What comprises those calories will obviously have a different effect on hormones, how they are stored and what they are used for.
    The biggest issue here is usually when carbs become the conversation and it becomes a long drawn out argument of whether they are needed by the body or not.
    Both sides have great arguments, but the reality is that when it comes to weight loss, it's usually going to just come down to calories in/out.

    Excess calories are stored as fat. It doesn't matter whether they started out as protein or carbs or what have you.

    Some people have medical issues and should watch their carbs.

    For me it's not about losing weight (?!). The more important thing is keeping the weight off. I've lost weight eating low fat....gained it back. I've lost weight eating low carb....gained it back.

    Lifestyle changes.....if you see yourself going paleo (low carb, low fat) forever....go for it. Making a temporary change and expecting a permanent result is silly (guilty as charged). Obviously many people do the temporary change because regaining most of the weight they lost is really common.

    a calorie is a unit of measure.

    If a calorie is not a calorie- than a tape measure is not equal to another tape measure. period.

    sucrose(s), carbohydrates, lipids, amino acids (proteins), will eventually be used to create energy for the body. They undergo different process, but when the body needs it, it will take it. Sugar > carbs > lipids > amino acids is the order in which the easiest way your body will obtain energy from. That's why when you eat a candy bar, you immediately feel the energy, because it's easy to break down.

    I'm no expert, but there are so many recent books and studies that suggest that a calorie is not a calorie. So it's open for discussion.

    Except on this site, where suggesting that a calorie may not be a calorie will be responded to with hostility, vitriol, ridicule and incredulity.

    You aren't kidding. So many here think they are experts and have the worst attitudes. I hope none of these people are actual professional teachers. Maybe they're so bitchy because despite being diet/nutrition/fitness experts they are still fat like a lot of us regular folks.

    My thought process was going more toward the likelihood that a sugar calorie will quickly be swept up into the bloodstream and used as 'brain food' rather than being stored, while the fat calorie will be stored unless there is a deficit. So I if I screw up and have my Reece's it will be brain fuel and not stored and if I screwed up and ate the pizza it would be more likely to be stored rather than immediately used. Just a thought. Nit-picking I'm sure, but it makes for interesting idea sharing. Thanks for your thoughts on both sides of the debate.

    In b4 prettykitty starts claiming members on MFP claim we recommend people eat a diet of all donuts but yet He never provides proof.

    Prettykitty, is this going to be the thread where you actually back your claims with evidence? Is it? Don't just say studies or evidence exists. Bring it forward.
    You don't recommend the Twinkie diet?

    OP use MFP to count calories and track your nutrients. Asking questions about sugar versus fat is like herding cats on here. So if you want to drop 21 pounds eat a slight deficit to your TDEE. Good luck.

    Protein speeds your metabolism and fat gets you into ketosis so those both have benefits that sugar doesn't...

    Interesting thoughts on both sides! I don't really have any investment, either way. I'm not planning to go paleo any time soon. I did try vegan and found it a bit more labor intensive than I care for and proteins ended up lacking because I just got sick of beans. But otherwise, I had no complaints. I do prefer to work out a balanced diet regime that works for me. Sometimes that includes meat or fish and sometimes it doesn't. I think I have more issues with portion control than on where those calories are coming from.

    Yes, a calorie is a calorie..but...the source of our calories are very different, and it matters greatly. For mere weight loss, eat whatever but have a slight deficit. For weight loss and optimal health, you need to give attention to the source of your calories.
    A simple example:

    A bowl of white sugar = 400 calories
    A bowl of grapes and a salad with olive oil and lemon juice = 400 calories

    The energy is the same, but the nutrition is different.
