    Not currently fat, perhaps. But if that have never been fat, they lack first hand experience of weight loss, which is probably worse from an advice point of view.

    Though I would still take advice from a never-fat dietitian.

    I would never take advice from a "nutritionist". It's not a real thing.

    A fat Personal Trainer or Nutritionist would get immediately ignored.

    So I've read on here how when it comes to weightloss, all calories are equal. A calorie is a calorie is a calorie. However, a friend of mine just told me that her nutritionist explained to her that this isn't so. She said that when you consume let's say, an apple, for 100 calories vs candy for 100 calories, the way your body is able to digest and break down each of these foods is different (using diff amounts of energy) there making the calories of these 2 foods not equal. Is there any merit to this idea?

    Regardless of what many on here preach, she isn't wrong. The type of calories you take in does effect the calories out. Proteins, in particular, require more calories to digest. Sugar, on the other hand, doesn't take much at all.
    TEF is given in digestion. And explain how calories out is affected?

    TEF is part of calories out. Calories out = BMR + TEF + non-exercise activity + exercise.

    to answer your question simply, digestion burns calories

    Yes different macronutrients effect energy expenditure through TEF/DIT, but unless you're making substantial changes to the macronutrient composition of the diet it's not going to amount to a significant change in energy output.

    Now you might see an appreciable difference in the long term when you make large changes and add up the additional energy expenditure over months.

    For all intents and purposes, speaking purely in terms of weight loss, a calorie is a calorie. There is a difference in the metabolic "cost" of processing between micronutrients (Google "TEF" or "thermic effect of feeding" if you want to geek out on the nuts and bolts of it), but for most people on diets of mixed macronutrients, it's all but completely irrelevant.

    When you factor in satiety/adherence, nutrition, workout performance and overall health, micro- and macronutrients matter. We're not talking purely about calories and weight loss anymore at this point, so it's a whole different discussion.

    We should just sticky this answer right here.

    The apple will have a higher TEF (Thermic Effect of Food)...it'll burn a few more calories in digestion than the candy will...it'll also provide more nutrition obviously.

    I wouldn't say the difference in TEF is significant enough to really say that a calorie (as a unit of energy) isn't a calorie...don't drown in this kind of munitia. Nutrition is a whole other ball game...on that front, eat a balanced and varied diet rich in whole food nutrition...and have a piece of candy once in awhile.

    The subject you're alluding to is the thermic effect of digestion. To be clear, the sugars in apples and candy are slightly different, but the thermic effect of digesting all of them is very low. The calorie from an apple is the same in your body as the calorie from a candy. The apple has some fiber and phytonutrients which are probably not present in the candy, so your 100 calories of apple is better for you then your 100 calories of candy, but it's still 100 calories. There is a place for the thermic effect of digestion to matter, and that is in the digestion of protein. Protein is hard to digest and the thermic effect of digesting protein is high. Therefore 100 calories of egg whites (the most pure protein) will deliver about 70 calories to your blood after the thermic tax is paid. The 70 calories, though, are the same calories as the 70 you might find in a lesser volume of your candy.

    It depends on the context. There is definitely a time and place for fast acting carbohydrates, especially if you are training for extended periods of time. So comparing foods in isolation is fairly worthless. The diet in context and the exercise requirements are what is important.

    The only significant difference between calories for the purpose of weightloss in my opinion is degrees of saiety. It varies person to person but most people find some foods more satiating than others and if you choose the foods that leave you satisfied more per calorie then you'll have an easier time losing weight.

    If instead you try to eat only the foods that have the "least" number of calories due to some sort of difference in metabolism or breakdown that isn't going to help nearly as much if those foods aren't satisfying for you.

    Eric has already answered this nicely. Are you under the impression that the digestive process doesn't require energy? Everything our bodies do requires energy. Those calories count just the same as if you burned them running.

    Eat the apple, it will fill you up more. Unless the candy is a delicious Reese's peanut butter cup, in that case, why not both?

    A calorie is just a calorie when it comes to weightloss or weightgain, this is thermodynamics. Those of us who follow iifym, dont really care where our carbs come from, as long as at the end we have our micronutrients. I diet eating pizza 4-5 times per week. Thermodynamics.

    Is your friend overweight? (Or her "nutritionist?") If so, I wouldn't listen to a word she says.

    If you're obese or overweight, count your calories and assume a calorie is a calorie.

    Don't listen to fat people? lol - that's your advice. Note we can't see a picture of you so how do we know to trust what you say? ;) (Your post made me chuckle mate)

    If people know what they're doing they wouldn't be fat. That would be my take on it.

    I've lost 90+lbs. I am still fat. I guess I don't know what am doing or talking about when it comes to weight loss....

    If you knew what you were doing, you wouldn't have gained 90lbs+

    I think he is saying if this person has been using this advice and hasn't lost weight then it probably doesn't hold water. Great job on losing 90+ pounds

    And in my experience, this should NOT be underestimated. This is an incredibly important part of anyone's dieting plan, and I think it is given way too little consideration.

    Figuring out what to eat so you aren't hungry, while maintaining a deficit, is so important... it prevents all those bad things from happening (overeating, binge eating, snacking on bad food choices... )

    I think that's ridiculous.

    I never said that people couldn't learn. You mean that people gain fat on purpose? What I said was that at the point (many years?) when people gain 100+ lbs they obviously have no idea about CICO.

    It is important. And everyone has to find out themselves what makes them satiated, despite some people asserting a certain way will always make you satiated or hungry.
