I originally stated that 1000 calories of healthy food is healthier than 1000 calories of fast food.
You are correct in that eating 1000 calories of both would be equal as far as weight gain and loss. However, 111 g of fat equals 1000 calories. Whereas 250 g of protein or carbs equals 1000 calories. So to achieve 1000 calories you could either eat 111 g of fat or 250 g of protein and carbs. Of course, all foods are a mix of the three but fast food tends to have a higher percentage of fat than healthier foods. So you could eat greater quantities of healthy foods than fast food for the same caloric intake.
Also, your body requires more carbs and protein than fat for nutrition.
So yes, 1000 calories is the same for weight gain and loss. But if you ate the same weight of both healthy and fast food you'd end up with a lot more calories from the fast food.
If there are any nutritionists on this board feel free to supplement or correct this information. I still find it a bit difficult to understand. |

I am a registered and licensed dietitian under the American Dietetic Association and the International Dietetic Association. I live in Incheon.
However, there is just something "special" about this website that turns people into raving contrarians when it comes to nutrition. For them, the only valid nutrition science come not from evidence based practices but from some grassy knoll in Dallas (or a rare mountain flower only accessable by yurt living sherpas who exist only on yak fat and berries shot by arrows at fast gallop). Therefor I seldom comment unless someone implied that they were feeding K+ through a PIC line.
But to lightly touch on what you said, source of calories is less important than total kcal. How one responds to hunger after eating in a source-resticted diet is another matter. You might want to look into volumetrics to get clearer understanding of wt vs. volume vs. kcal. as well as what really constitutes "healthy food". |

| Another thing to add is weight gain or loss is different from fat % and fat gain or loss. For me weight is not the issue, it's reducing fat %. More importantly it's the fat inside the organs that is the toughest to reduce, not the fat that lays on top of the muscle. So personally calories is just a top level check, it's more about the quality of ingredients i'm ingesting as well as the amount of fat is in each meal. |

But health is not simply about weight loss and weight gain. Are you suggesting that what a person eats is irrelevant as long as his weight (and maybe fat percentage too) is optimal? Too low fat percentage is unhealthy too. As long as you stay within a healthy weight and body composition, the focus should be on eating healthy food and not about the number of calories you eat.
But I agree with the nutritionist that must health discussions here take a wrong turn somewhere along the road, but it's always fun to read about mountain flower extract infused with indigo tea which cures cancer and gives you super powers. |

"Too low fat %" that'd be a nice problem to have...although it depends on the body structure. Bruce Lee purportedly had very very little body fat % and was healthy until his sudden death of course.  But i think this is where standards such as BMI and 2000 calorie intake suggestions can come in handy. |
