slimness - is it related to eating habits?

the person's metabolism is associated with this. even if they eat a lot, their body burns up the energy fast. thus, not much fat is stored. those with slower metabolism tend to be more on the heavy side. genetic is also a factor. i am diabetic and i had a few nutrition class before. if you would count your daily calorie intake thru monitoring the food that you eat and then you'll hit the gym, they have some counters there that helps you see how many calories you burned thru an hour in the treadmill/elliptical trainer, that is closely related to weight gain or weight loss too. well, thats just what i know. maybe a medical doctor can explain more about this.

I am one such person who can eat chocolate and lot of fatty foods, but yet put on no kind of weight...if I do gain a few pounds it comes right back off. When people ask me how I manage to retain my figure I say good genes, even though this may not be the case. To me, in my case, it is a mental thing, I tell people I can't get fat, and I have never gotten fat...but I also think it has ot do with how you really eat. I do not eat chocolate everyday or fatty foods everyday...I have what I call my detox days when I would just eat a salad and be ok. Then too, I also eat a lot of fruits and steam vegetables.

Yes it is right that slimness is not affected by eating habits. I eat a lot but still remain very slim. It depends on the amount of energy you burn. It is not necessary that you play sports, using your brain, like in mathematical problems, burn a lot of energy. So it's just a myth that eating a lot makes you fat.
