Low-fat v. Low-carb diets - new study

Low carb for cutting isn’t about losing more weight or weight faster. It’s about body composition and trying to lose as little strength as possible.

Calories in vs calories out is the only thing that matters for pure weight loss.

I am going to be that guy and say "Close." Calories are all that matter for "fat loss." Macro profile has everything to do with body composition with water weight.

So technically, keto diet will always lose more weight. Fat loss can be the same in both types of diets though.

true, I should have typed it that away.

No worries. I knew you knew. I was mostly saying it so that people start using the wording correctly because it can cause confusion.

It was an inner monologue that went like this " I know 777 knows this stuff but damn did he just make a rookie move. I hate to be the guy to tell him. However tough it may be to his ego that he royally screwed the pooch, he has to be told otherwise he might come off as "special." That's not what I want for my bro. I'll just take the fall and be "that guy" so that he can be protected."

Every time my wife forces us on some low carb diet, I lose weight. Maybe I am eating fewer calories, I have no idea. I just know I lose weight.

No carb intake has been shown to have zero relevance on fat loss.

Like I said above though it has other benefits like blunted hunger that help weight loss in the long run and has a myriad of health benefits.

See the triangle below. It's calories, then did you get enough protein. After that everything else is just lagniappe and trying to get as close to optimal as possible.

And that is 100% true and so is the study in that when calories are constant fat loss remains consistent whether high fat or high carb.

This has been proven to be true over mutiple studies, what you said has also been proven true.

The only study I know of where it was proven macro levels mattered was the original fat fast and protein sparing modified fast studies from the late 50 and early 60s but they were focused on caloric levels well under a thousand calories

That study was a waste of time in comparing:
In the HLF vs HLC diets, respectively, the mean 12-month macronutrient distributions were 48% vs 30% for carbohydrates, 29% vs 45% for fat, and 21% vs 23% for protein.

The difference between ketosis diet and other diets is that when you are in ketosis your body only uses fat as the fuel. All other diets are insulin based. In a carb or protein diet you will still break down muscle for energy if you are in negative calories while the ketosis diet does not. There is no sense at this point in doing anything other than fasting to lose weight. Fasting boosts your growth hormone levels super high and turns on autophagy. Autophagy won the Nobel Prize in medicine in 2016 for its huge health benefits. If you can't not eat to lose weight then ketosis is the next best. Hormones are super important.

What if we told you that following a ketogenic diet does not necessarily mean losing your precious muscle mass? Here is the evidence.

High protein diets are high in cortisol which can lower testosterone. You don't need to go to such stress when there are easier and healthier options for you. High carb diets, if gluten heavy, can wreck your gut and your persona ( How the Gut Microbiome affects the Brain and Mind)

Because to achieve ketosis you are burning the fat you are inputting into your body in the form of food. You burn that fat plus any body fat needed to make up the caloric deficit.

Fat is the easiest macro to burn for fuel once fat adapted. It's also the easiest macro to store as fat.

Again there is not a single study done in the last 30 years that accounts for amount of calories that show low carb, no carb or any form of carb restriction burns body fat at a higher rate than a iso caloric diet over a course of at least 6 weeks. Any difference has been nelgible in studies.
