Let me clarify, the satiation factor is what I was getting at, but totally forgot the word for it
You will feel better eating the so called "good calories" than sugar filled products that will make you hungry just a short time afterwords.
I'm in complete agreement with you, but just wanted to bring up some of the qualitative differences in eating crap ("bad calories") and eating healthier foods ("good calories"). You will feel better and satiated longer with the "good calories". Sorry for the confusion.
Well, we're saying the same thing, I just don't refer to it as "bad" or "good" calories, because it gives the impression to less informed people that there is actually a difference in let's say a fruit calorie and a meat calorie. They are the same thing, they just give your body different signals.
However, it's wrong to say that even the "empty" calories are bad. Usually, we're talking about high-carb calories that are mostly sugar based when saying "bad" calorie. However, even these products have value. After a good workout that involves a lot of energy expenditure (think swimming, running, cycling, elliptical or other cardio intensive workouts), sugar filled calories can quickly replenish your energy levels while also providing your muscles with a source of glycogen to replenish them. Ingesting a low carb - high protein calorie source after such an exercise would mostly be usually as the workout didn't really destroy your muscles like a weight-training or other strength-based workout would have.
While both could provide the same amount of calories, and the weight gain/loss effect would be the same for both, one or the other will result in a difference in your body. One might help you burn fat and leave you feeling relaxed and ready for more while the other might result in you burning some muscle mass and leaving you tired.
That's why I bring 2 supplements with me to the gym : One high-glucose source of energy for post-cardio and one high-protein supplement for post muscle training. I balance out each to give me proper sugar, protein and calories as to not mess with my weight and leave my body fully functional when I step out of the gym, ready for chores at home or a night out with friends.
There is. For example protein can be used to build muscle, whereas simple carbs are more or less useless to our body in terms of muscle growth. You won't gain fat unless you eat too many calories, but the quality of calories is also important.
I should have clarified a bit more : There is no difference as far as body weight goes in a calorie. A calorie is a calorie as far as your weight gain/loss is concerned. How you gain/lose weight will depend on the type of nutriments found in that calorie and the type of nutriments your body needs (over-dosing on proteins won't magically make muscles appear, it'll just result in high protein based piss coming out while your body will still be gaining fat if you ingest more calories than you spend).
