Keto Diet Results for Weight Loss

Posted by

“Keto Diet Results for Weight Loss” The carbohydrate-insulin
model of obesity, the underlying theory that ketogenic diets have some sort of metabolic advantage, has been experimentally falsified. The keto diet’s proponents’ own
studies showed the exact opposite: ketogenic diets actually put
you at a metabolic disadvantage and slow the loss of body fat. How much does fat loss slow
down on a low-carb diet? If you cut about 800 calories a
day of carbohydrates from your diet you lose 53 grams of body fat a day, but if you cut the same
number of fat calories, you lose 89 grams a day. Same number of calories,
but nine pats of butter worth of extra fat melting off your body every day on a low-fat diet,
compared to the low-carb diet. Same number of calories, but
about 80 percent more fat loss when you cut down on
fat instead of carbs. Here’s the graph. Cut 800 calories from
your diet by cutting carbs and you do lose body fat, but cut out the same number
of calories by cutting fat, and you lose even more body fat—
80 percent more body fat lost. The title of the
study speaks for itself: “Calorie for Calorie,
Dietary Fat Restriction Results in More Body Fat Loss
than Carbohydrate Restriction in People with Obesity.” But just looking at the
bathroom scale, though, would mislead you into
thinking the opposite. After six days on the low-carb diet,
study subjects lost four pounds. On the low-fat diet they
lost less than three. So, step on the scale
and it looks like the low-carb diet
wins hands down. So, you can see why low-carb
diets are so popular. But what was happening inside
their bodies tells the real story. The low-carb group was
losing mostly lean mass— water and protein. This loss of water weight helps
explain why low-carb diets have been such “cash cows” for
publishers over the last 150 years. That’s their secret. As one weight loss expert noted, “Rapid water loss is the
$33-billion diet gimmick.” When you eat carbohydrates,
your body bulks your muscles up with glycogen for quick energy. Eat a high carbohydrate
diet for three days and you may add about
three pounds of muscle mass onto your arms and legs. Those glycogen stores drain
away though on a low-carb diet and pull water out with it. And the ketones also need to
be flushed out of the kidneys, pulling out even more water. On the scale, that can
manifest as four more pounds coming off within 10 days, but that all can be
accounted for in water loss. The bottom line: keto diets
just don’t hold water. But the thrill of seeing the
pounds come off so quickly on the scale keeps
many coming back. When the diet fails, the
dieters often blame themselves. But the intoxication of that
initial rapid weight loss may tempt them back, like getting
drunk again after forgetting how terrible the last hangover was. This has been dubbed
the “false hope syndrome.” The diet industry thrives
off of repeat customers, something low-carb diets were built for, given that rapid initial water loss. But what we care about is body fat. In six days, the low-fat diet extracted a total of 80% more fat from
the body than the low-carb diet. And it’s not just one study. If you look at all the
controlled feeding trials where researchers compared
low-carb diets to low-fat diets, swapping the same
number of carb calories for fat calories or vice versa. If a calorie is just a
calorie then all the studies should have crossed that
zero line in the middle, and indeed six did. One study showed more fat
loss on a low-carb diet, but every other study
favored the low-fat diet, more loss of body fat eating
the same number of calories. Put all the studies together…
and we’re talking 16 grams more daily body fat loss
on the low-fat diets, that’s four more pats of butter melting off your body
on a daily basis. Less fat in the mouth,
means less fat on the hips, even taking in the
same number of calories.


  1. This is the 3rd installment of my keto series. In case you missed the first two, see Is Keto an Effective Cancer-Fighting Diet? ( and Keto Diet Theory Put to the Test (

  2. LMAO!!! Gregor is basing his results on a 6 day test!!! OMG, for some people, it takes that long just to get into Ketosis! But the real kicker, is that it takes 30 days to 12 weeks to get fat adapted when on a Keto diet, and that’s when the real power of Ketosis helps you!

    And of course you lose water on a Keto diet. That’s because glycogen attaches to several water molecules, and so when you cut back on carbs, you burn up your glycogen and shred water. But that doesn’t mean your losing muscle mass, your just losing the water that was in your muscles! That’s why body builders “carb-up” the day before a competition. But did Gregor explain this? Of course not! But AFTER you lose your water (which oddly takes about 6 days, which was the length of this flawed test), you then lose fat!!

    If you look at any long term Keto diet study, they all show that Gregor is clearly wrong (see below). Once again, Gregor shows he knows how to cherry pick flawed studies, to appease his potato head cult followers.

    Does Thomas DeLauer, a long time Keto diet advocate on YouTube look like he has a problem with muscle mass (see below):

  3. Somebody send this to Joe Rogan. He’s probably responsible for 100k fans upping their risk of heart attack and stroke.

  4. Notice that everyone of the studies references are from Kevin Hall, the notorious keto diet hater. Can you say confirmation bias?

  5. so i guess the 171lbs i lost doing keto after being diagnosed with heart failure and dilated cardiomyopathy was not only bad for my heart, but my doctors were wrong. nice try! cherry pick some more. oh and by the way keto not only saved my life but i also don't need a heart transplant anymore! thanks to KETO

  6. What I have found out in years of study and blood analysis on my body is that fat does not cause arterial inflammation like carbs and sugar. After four heart attacks I quit allopathic western medicine, not one MD talked to me about food and diet, I am now a trained medicinal herbalist and diet/food researcher. My knowledge way exceeds the doctors I used to go to, Dr. Greger is the only one that’s even close. My world revolves around arterial inflammation and what foods/herbal extracts suppress it and what foods cause it. Even the vegetable world has foods I won’t eat.

  7. This really explains the drastic change of appearance for Jordan Peterson, who has eaten an all beef and salt diet for well over a year now. He has lost a lot of weight, that’s for sure. However, I wouldn’t say that he looks very healthy as he looks like he’s lost a lot of muscle..

  8. Perhaps people have success on low-carb because they feel satisfied eating less calories? I think people like low-carb diets because they are easy to follow, it’s easier to eat less because you feel satisfied sooner. Any studies on the feeling of fullness on low-carb diets vs non low-carb diets?

  9. I tried the keto thing before I was better educated on how to verify legitimate research. Let me tell you, even when I was increasing my fiber intake and staying keto, I was constantly wiping my butthole. All that extra fat was doing something awful inside my guts. I would go on runs and my butt itched. It was horrifying.


    Read it and weep.
    A proper long term study my Carb loaded vegetable happy friends.

  11. The main thing about the keto diet is that you eat fewer calories because you're satiated quicker. Think about your personal experience. How easy is it to overeat pizza or cereal or cookies? It's much more difficult to eat the same number of calories of meat, eggs, avocado, etc. Dr. Greger doesn't even go into this fact AT ALL. Hopefully he'll address it in a future video. It definitely feels like he's cherry picking the studies for this video.

    Personally, I'm still on the fence which way to go – ketosis vs WFPB w/ fish, but leaning towards WFPB. It seems like every person on YouTube is biased and cherry picks their info….so frustrating. Are there any unbiased and open nutritionists out there?

  12. You do keto for a couple of weeks and then limit the carbs you bring back into your diet you idiots! Keep the carbs under 150 grams a day as lifestyle. I average about 100 if that and am happy and healthy. And grateful as all hell that I kept an ear open to opposing views all along. Go ahead and eat a bunch of fruit and grains for all I care; want to talk about a diet that doesn’t last long for most.

  13. Wow apparently i lost 100+ lbs in the last 2 years the "wrong" way (keto)! I should go back to my old low-fat diet where I was getting fatter and fatter for 15 years. Thanks doc!

  14. Diet regimens should ideally be long-term lifelong strategies for remaining healthy and living long, not for overweight fat and obese people to temporarily invoke just for the purpose of dropping some quick body poundage. People are easily tricked, following the hyped commercials and media intent on shrinking their wallets. This presentation today reinforces what I have intuitively thought all along, and it's great to see valid studies finally putting this modern myth to bed for good. It will be quite fascinating to see if and how the Keto community will respond to your talk Michael. The Keto industry is huge these days, with too much money, reputation, and pride invested to simply roll over and admit they were on the wrong course, misleading people all along, whether by intent or innocent ignorance of the facts. Let's see what happens now!

  15. All I know is going on a keto diet makes it easier for me to eat less and not feel hungry. No other diet has ever helped me do that. 1500 calories a day, fasting long periods, not feeling terrible after eating tons of carbs. the study needs to measure the human component not just the theory of increased fat loss based on calories on vs calories out.

  16. I wonder if this has something to do with it being "low carb" and not "0 carb". Pretty much only fat, non statchy vegetables and low protein. Combined with fasting and refeeding days. I wonder if that would have different results
