Low carb is great for many people, but lots more think it's the only way to lose weight.7

The idea is that carbs are a source of calories that our bodies can use readily. Carbs are long or small sugars which our bodies break down in chemical processes and convert into energy-creating molecules. This process is much faster than with fats or proteins (both of which are also converted to energy-creating molecules).
Theoretically we can even become addicted to them. Have you ever gone off carbs, eat something with carbs, and then all you crave is carb-loaded foods (pasta, pizza, doughnuts, a sandwich, etc.)? Well the thought comes from the fact that our bodies use carbs so readily so we crave the "easy energy."
Then, once we've filled up, our bodies convert it into glycogen, and after a long time of eating too many carbs, the body starts converting carbs into fat.
Carbs are not the devil, but getting our calories from proteins and fats is generally deemed healthier.

FIFY...carbs aren't converted to fat when eaten in excess...calories are26 -
Generally 1 of 2 reasons...
- They are under the impression that they have to restrict/cut out carbs in order to lose weight. This is wrong, or at the very least, REALLY INCOMPLETE advice that often comes from magazine headlines, TV "doctors", or people looking to make money off of diet plans/advice.
- They realize that to lose weight they have to manage/restrict calories, and they choose to do so by cutting back on carbs based on their own dietary preferences (i.e. they'd rather cut carbs and keep fats and/or protein).

They think it's needed in order to loose weight or they do so to control their appetite.
It's not needed to loose weight. You loose weight by being in a calorie deficit.10 -
Once I lost my fear of carbs I discovered that I can moderate most carbs quite easily.
While losing weight more rapidly during my first year on MFP I ate a slightly lower percentage of carbs (44%) instead of my subsequent steady 53% over the next three years.
This is because I prioritized protein, fiber, and fat targets by gram, and in that order, leaving carbs to fall where they may while achieving my caloric goals.
Since my caloric goals were lower, that left less room for carbs as a percentage!
I do still have some trouble moderating caloric sources that combine carbs and fats in a hyper palatable bundle. I indulge often, but do have to keep an eye on things and invest will power to moderate when I do so. (I'm talking baked goods and candy bars -- no problem over eating these if I don't pay attention
)
But baked potatoes are also starches (carbs) and combined with a 0% Greek yogurt instead of butter or sour cream, or topped with some chili they make a solid and usually satisfying meal.17 -
Me personally... Because carbs= sugar and my body is refusing to process sugar now and the diet I’m on to sort out my blood sugar levels, makes my body burn fat if it doesn’t have sugar .

Because it's a huge fad right now (along with intermittent fasting) and people mistakenly believe that weight loss is faster on a low-carb diet. Which has repeatedly been scientifically disproved.34

You have to cut back somewhere - sugar, starches and grains are low hanging fruit.21

Hmm. Not if your workout is physically demanding. But yeah, no/light exercise doesn't require much carbs.12 -

Maybe if you're an elite athlete but whether you eat carbs or not your glycogen stores aren't empty. Eat whatever diet you prefer, train and you'll adjust and progress - humans are remarkably adaptive.13 -

We are adaptable but only a handful of people can train hard 4 times a week with cardio included eating low carbs. You won't last long then eventually regress. But doing something lighter, yes.12 -

I'm not sure what "FIFY" means but the rest is not true. "Calories" are a unit of measurement of energy, while "carbs" are a physical thing (molecules). I did mention I was an organic chemistry student and I have some semblance (albeit not the best) of an idea of what I'm talking about.

Then hopefully you also understand which macronutrient is most easily converted to fat.
(Hint: fat)
De novo lipogenesis only happens under situations of massive, sustained carb overfeeds - far beyond what the average human on a non-ketogenic diet eats on a daily basis.
And hopefully you also understand that there is no net fat storage while in a caloric deficit, regardless of the macronutrient composition of your diet.26 -

FIFY = Fixed It For You
If you are in a calorie surplus, any food you eat, regardless of it's macro ratio, will be stored as fat. If you are in a calorie deficit, there is nothing to store as fat, regardless of what specific food you've eaten.
And I haven't seen anything credible to suggest that eating carbs is not as healthy as eating protein and fat, do you have any sources for that? Check out the Blue Zones.
OP, low carb is popular right now, so many people assume it's "best". The people it works well for are generally more satiated by fats than carbs, so they can more easily keep to their calorie deficit. There are also some medical conditions that there is some anecdotal at least suggestion that a lower carb diet may help.20 -
I think when you exercise you burn mainly carbs and some fats. At lower intensity you will burn a higher percentage of fat, and higher intensity you will burn a lower percentage of fats. But still mainly carbs.
So I think the more you exercise, the more carbs you need to fuel your workouts.
If you don't exercise, I don't think you need that many carbs.23 -
Because people have preferences. Some are smart preferences, and some aren't.
Which ones are smart (or not) is pretty individual - other than proper calories, and well-balanced nutrition, which we all need.
The trick is to figure out your preferences.

Corrected my comment. Some are capable, most aren't. Plus I personally have no reason to not eat carbohydrates.3 -
You might wanna just Google ketosis. This is a very complex question5

Because I am type 2 diabetic with insulin resistance14

Well, I eat low carb because I'm a diabetic so my body doesn't process carbs properly and my blood sugar can quickly rise to dangerous levels if I eat too many. Some people have other conditions such as PCOS which respond well to low carb diets.
Even if you are healthy, carbs digest more quickly than protein or fats, so they may not be as filling for you. This is a matter of individual preferences - some people find that carbs work just fine for their satiety levels, some don't.
The point of super-low diets like the keto diet is to cause the body to use ketones, a byproduct of breaking down fat, for energy, instead of carbs. If you are the sort of person who craves bacon and never craves cake, this may be a good approach for you. But it's not magical and studies have found that people lose just as much weight on a keto type diet as on any other diet, if calorie intake is the same. It's just one way of restricting calories.

I'm sorry that it seemed I implied a calorie deficit, I thought that was easily read. When I said carb excess I did in fact mean a calorie excess as well. I disagree that fat begets fat. Here's an article on the contrary: https://paleoleap.com/demolishing-fat-makes-fat-myth/FIFY = Fixed It For You

Again, I did not intend to imply a calorie deficit! A carbohydrate excess and calorie excess will cause weight gain. No, I can't pull out my textbook right now and tell you exactly where I read that. (Are we all A+ students? No.). Here's an article on the low-down on carbohydrates: http://goaskalice.columbia.edu/answered-questions/does-carbohydrate-become-body-fat (Yes, I admit Alice and I have probably read different articles on how carbs may or may not be directly responsible for fat-creation... I'm just telling you guys what my professor told me
)
Honestly though, the animosity on here is devastating
Sorry I didn't come in here with resources but it didn't look like we needed them considering nobody else has placed links in their posts.

I don't understand this. As far as I can tell you were engaged on your views in a very mild, civilized, and matter-of-fact way. Since when did any confrontation become devastating animosity?
ETA: Also, if you want links yourself feel free to ask. I am sure someone will oblige.21 -

Some of us need to do it for health reasons. I have diabetes and I was told to eat lower carb to help manage my sugar levels. I personally love eating low carb. Carbs were a big part of the problem when I ballooned up to 370 pounds because it was easy for me to eat a lot of carbs and they added a significant amount of calories. Eating low carb feels better for my body too. It's all about personal preference and only you can know exactly what your body requires in regard to macros.2

I can't see any reason not to eat carbs as long as they are the right kind of carbs. Avoid the white flour and starchy kind (especially if you are diabetic) But fruits and vegetables are carbs and fine to eat. Even the dreaded potatoes and corn are okay in small quantities. NOTE: I am not a medical professional. My opinions expressed herein are based on my reading and a meeting with a registered dietician. Take it for what it is worth.20

"Eucaloric" means no caloric excess or deficit. Again, already covered that.

Not diabetic. The only hindrance I have ever noticed to eating the "bad" carbs is that if I don't eat enough protein with it/them I am not satiated for very long. Otherwise I don't see how it makes a difference to my personal progress.
