Not trying to stir any trouble, but I have an honest question about LC eating.
Many on Paleo or LC sites seem to think that carbs are the devil as the carbs are eventually just are stored as fat in the body. However, it seems like these people are forgetting that dietary fat is also stored as fat much more easily than carbs. Therefore, replacing carbs with fat really solves no fat storage problem. I understand that reducing carbs burns more fat, but if you are just replacing the burned fat with more dietary fat (which is stored as fat), are you really losing that much overall fat? (Sorry for confusing wording)
As a personal anecdote, I was already in low body fat range but could not lose last pounds on low carb. Then I reduced my dietary fat intake, added more starchy carbs, while still eating tons of protein, and voila -- I began losing. I am not saying I don't eat fat -- I just reduced it a ton and replaced it with protein. That was the trick for me. Just sharing my experience in case others are having same problem
Any ideas about this?

"Carbs are the devil as the carbs are eventually just are stored as fat in the body."
Sure, some people still believe that, but it is not true. Your body rarely stores excess carbs as fat, so not sure why people would say carbs are eventually stored as fat. Instead, when you have an excess of carbs in the diet, your body will then store all dietary fat first before it attempts de novo lipogenesis. It's just more efficient.
In any case, eating too many calories, at the end of the day will make you gain weight and vice versa.
When going low carb, to me, you are using a strategy to help you get into a caloric deficit. I know for me, eating more fat keeps me satiated longer, and I can go longer between meals. For some, going into ketosis helps them eat less and help promote their body to ketones for fuel, thus decreasing hunger.
Of course there are other factors, but please don't fall into the type that carbs are evil and equal fat gain. One macronutrient is not good or evil. Sticky with safe starches, healthy fats, good sources of protein. Tinker with lowering fat or carb when trying to lose weight. In you example, cutting back on fat did the trick. We are different and thrive on different ratios.

It's not that carbs are stored and fat isn't, it's that carbs cause a hormonal cascade that favours fat gain.

Fuels for the body in the order your body uses them are carbs, fat and protein. The reason your body uses the carbs first (at least as I've come to understand it) is that it doesn't need carbs to survive (though you're still getting carbs from vegetable obviously)...if you remove carbs as a source of fuel and give it something besides the refined carbs i.e. fat...It has no choice and burns the fat for fuel...fat goes in...Fat is burned away...I could be totally wrong, but this is how I see it working in my brain under a factory type setting.

if paleo/LC diets was only about the oversimplification carbs=stored/ fats=burned [which is false], I wouldn't be on paleo whatsoever.
What "convinced" me, was a list of other hormonal/biochemical facts. I cannot say it is the "holy truth", but it is largely supported by physiology studies and mechanisms. Here's the list:
- carbs are insulinogenic, unlike fats, insulin switches on lypogenesis and switches off all those wonderful catabolic pathways that makes us leaner and burner-organisms.
-carbs are pro-inflammatory and drive the glication process. Glicated proteins are impaired proteins, suboptimally functioning. Enzymes are proteins as well, our metabolic machines.
Carbs do not satisfy us as fats and proteins do. We are likely to fall hungry easier and earlier after a meal: when gluconeogenesis and glicolysis produce glucose for your blood, glicemia is steady. When glucose is eaten, bad.carbs in particular, glucose levels are more unsteady and cravings,hunger,energy drops ensue.
for sugar-sensitive people (like I am...) "the more carbs you eat, the more you crave".
These are good points to me, physiology- based. "Absolute" truth?don't think so. Genes can add lot of different outcomes indeed, not to mention that a single hormonal inbalance could affect metabolism.
Generally speaking, if the goal is to lose weight, you can do in thousands different styles with the condition to stay on HYPOCALORIC mode. If the goal is to "heal" the metabolism, the "burning system" and get rid of the skinny-fat body type (kind outcome of all my low fat diets...), I'd go for something different.
last: 1g carbs=4.5 Kcal; 1g fat=9 kcal. I wouldn't be surprised by the weight loss after replacing fats with carbs. That's not the point, the point is the switch to less calories.
Within isocaloric intake (life long/no hungry all day), 25% carbs make the difference...for me).

Have you tried working out with a trainer? That's been kicking my butt. I'm new to Paleo but not to low-carbing. In the same boat - at a standstill. I feel like our bodies have a "set point" and breaking it is sometimes hard. Try counting calories too perhaps.

Actual preneolithic diets could not possibly have been high fat. Read the following summary by Matesz:
Fat was not easily retained before cooking vessels. Matesz speculates on a 55% carb, 25% fat diet in Paleolithic Africa. Even modern low fat diets contain that much. The macronutrients in the paleo diet were similar to the Med diet.

If you want to know the science behind proteins, fats and carbohydrates, there are numerous chemistry sites online that display the molecular structure of the different fats and carbohydrates.

How long did you try alternate diets each? How long did it take on your low carb to lose the initial weight?
Do you consume any sweetners/diet drinks etc.. anything other than whole real food? What was your % of dietary fat/carbs on LC?
What are you doing now?

I lost 35-40 pounds since going paleo.. I ate high fat and very little carbs, till I flat lined at 190 lbs.. I tried to shake it up and eat some carbs .. and i didn't gain a pound i just felt sluggish.. I tried to go real strict and I didn't lose a pound... I switched to lower fat .. nothing...I switched to higher fat.. nothing I stuck where I was ... I would like to lose another 30 which would be ideal as a 5'4" male, I know Ideal is a meaningless term but for once in my 32 years on the earth i would like to say I know what the FDA says I should be and what a crock it is. Frankly I can't diss the medical records till I prove them wrong, I know i still have High body fat. I still have a large keg belly and man boobs ..
I know its going to take a cleanse, some time with out carbs at all, with low fat, maybe a liquid fast, a raw veggie fast and full time exercise, but I would to know what that is like while still young enough to feel it ..
any one else
