great argument in here fellas..
IMO, carbs don't make you fat, fat doesn't make you fat.. it's the combination when in a caloric surplus. One of Lyle's books even touch on this briefly. If you are in a calorie excess and taking in more carbohydrates than needed, all dietary fat will be stored....
The real culprit is a high carbohydrate and high fat diet made up of refined and processed foods since near birth that just destroys our insulin sensitivity. Our cells get desensitized to the insulin and therefore the nutrients end up getting stored rather than burned for fuel. Once you increase your insulin sensitivity it gets much easier to drop and nutrient partitioning is much more pronounced at that point.
I haven't read a nutrition book in ages, so I would look like a jackass if I tried using big words.. haha..
This is my only issue with whats been said. Dietary fat has a bigger potential to be stored as fat. This is a fact and really can't be argued. At the end of the day, excess Calories is what matters, but in a surplus, fat always wins. I mean just think about it.. think about what carbohydrates have to go through in order to help be stored as fat. Then compare it to actual dietary fat. Heres an excerpt for you.
"After consumption, dietary fat is broken down repackaged into something called a chylomicron, absorbed into the lymphatic system, and appears in the bloodstream about 3 hours after you eat. While a certain percentage of ingested dietary fat will be used for energy or go to the liver or skeletal muscle for either storage or burning, some proportion will always make it to the fat cells where it can potentially be stored. This is unavoidaable" --Lyle McDonald
So, let me you ask you this.. how exactly does excess carbohydrate trump excess fat is storage capabilities? And explain the study I linked that demonstrated..
"After 8 control days of isocaloric energy balance, subjects on the 9th day were given an additional 1000 kcal in order to create a hypercaloric energy balance. As a result, carbohydrate and protein balance were achieved (oxidation equaled intake) while fat storage was preferential over fat oxidation."
Remember, a high carb diet also has a high carbohydrate oxidation..(not storage) While this DOES suppress fat oxidation, it does not contribute to a large fat gain. So, I'll simply say, there are advantages to lower carb diets if fat loss is your goal.. but I think we are talking about hypercaloric conditions where body masses increases.
This is really splitting hairs, because thermodynamics matters most. But I'll gladly split these hairs because everyone learns from it. I know I learn more and more when challenged and am forced to look up facts over matters.
I guess I should have said I believe carbs make a bigger difference when consuming all 3 macro nutrients, not necessarily by themselves. Obviously dietary fat can be stored easier than carbohydrates can be converted. I think many people underestimate/forget about insulin however.
Threads like these make me think us lifters are taking things off-the-deep-end!
I'm way to simple minded to bother truly understanding all of this. I'm sort of on the side with Allen, you gotta find what fits your body best.
Also gotta agree with Rich, if you eat an excess of calories then you will store fat regardless of where it came from or what it came from. Maybe one day I'll read this thread again and it will make more sense.
