As both study groups acknowledge, additional research is needed to tease out any and all of the factors that may be producing the weight loss and decrease in HbA1c, says Dr. Gonzalez-Campoy, for example there may be other mechanisms of action that are helping these individuals to achieve weight loss, including changes in the gut microbiome, increased insulin sensitivity, enhanced leptin response, and decreased ghrelin levels, each of which contribute to weight loss.
After the depletion phase, your body will enter a survival mode where it starts to signal the liver to produce ketones from available dietary fat sources and body fat stores. These ketones will replace glycogen as the body’s fuel source in the absence of glycogen. The body will go back to burning glycogen for energy when you start eating carbs again.
Glucose is stored in your liver and released as needed for energy. However, after carb intake has been extremely low for one to two days, these glucose stores become depleted. Your liver can make some glucose from amino acids in the protein you eat via a process known as gluconeogenesis, but not nearly enough to meet the needs of your brain, which requires a constant fuel supply.
The average person's diet contain about 55% carbohydrates, 30% fat, and 15% protein. On the keto diet, you eat a whole lot more fat, and a lot less carbs: 80% of the diet is comprised of fat, 15% is protein, and a mere 5% of calories come from carbohydrates. For someone on a 1,500-calorie diet, that translates to 19 grams of carbohydrates per day, which is less than what you find in one medium-sized apple.
A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

Well… what are many people on a Keto diet trying to do? Lose weight right? I would guess that prior to discovering the Keto diet many of these people were caught in the trap of low fat dieting. This lead to months or years of low fat intake and consequentially low gallbladder activity. The gallbladder wasn’t needed to digest fat and so it sat idle and stones were more likely to form. Once they made the shift to a ketogenic lifestyle and their fat consumption increased upwards of 1000%, the gallbladder kicked into high gear. If the previous period of low fat dieting had caused stone formation they are going to have to deal with flushing those stones out now while on a high fat Keto diet.
A second counterintuitive approach to healing the gut for children who are having a hard time gaining is to encourage a nice long ‘fast’ over night. When the gut is less full, and the body can digest the food that’s in there completely and then it can repair an inflamed or leaky gut better. If the gut is inflamed, food may be passing right through without being absorbed. In addition, growth hormone raises during periods of fasting.
“When you start the keto diet, you lose sodium and other electrolytes in the urine due to reductions in insulin,” says Yawitz. “This is a major contributor to symptoms of keto flu.” So it’s important to replenish sodium through the diet, especially if you exercise or sweat a lot. “This can help ward off more serious side effects that are seen with long-term sodium deficiencies,” says Yawitz. These include lethargy and confusion — and in extreme cases, seizures, coma, and death, according to the Mayo Clinic.
Here’s another controversial yet promising area of study: Research suggests that when patients with diabetes take on a low-carb diet (like keto), they experience improvements in insulin sensitivity by up to 75 percent, as well as a reduction in blood sugar control medications. What we aren’t sure of, however, is whether these improvements are due specifically to the effects of ketosis or to weight loss in general, so similar results could theoretically be found with any successful diet.
Truly Dr. Colbert is also a reputable source for more thorough science and modification of previous Keto extremes. The statements about Keto diets with dairy everyday are not true…I am a 66 year old professional (University trained) and have found medical people often very unknowledgable or partially knowledgeable which may be worse. I ask you Abbey to dig deeper…meet Dr. Colbert-not a quack and more in depth than your overview. Personally I am finding switch to more green’s and low glycemic vegetables and fruits with healthy fats, occasional dairy and healthy protein; a way of life that is helping our whole family. Please watch The Magic Pill…the help for family’s caught in old thinking from poor science (ie. Alex Keys) and with autism etc. and so much modern disease is in itself, motivation to search out more truth.
I actually clicked on the story just to see if they included anything about it’s use in managing chronic migraine. I have chronic migraine, basically intractable. Nothing has helped. I’ve tried medications, meditations, and everything in between including a bunch of dietary changes. Keto is my next consideration. I’m happy to hear it helped you! Thanks for sharing
Luckily today, we do not have to treat any type of diabetes with this barbaric method. There are so many healthy food options for most people today in modern society. In America, most of us are blessed to have access to healthy food options. I did see the research that Dr. Westman has completed at Duke University and did reference one of his articles above (reference #7 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1325029/). I have no doubt the diet works, I’ve done it and lost weight really fast, so I know from firsthand experience that it works. You will lose weight which will have wonderful effects on every aspect of your health. The problem I have is, can anyone go the rest of their life without consuming anything white EVER? Do you think every author of all those books actually does that? I would offer to put them all on a lie detector to prove that they haven’t lived 40 years without consuming one white thing or one fruit or anything with sugar in it. My question is, what quality of life do they really have if they have? I for one will NOT be giving up my or my family’s birthday cake!
I am a 7 year stroke survivor that is partially paralyzed from the stroke. I work part time and while working I walk at least 2 miles at work three to five times per week, but I can only walk 1 mph if even that speed. Which I know average speed is 3 mph when walking. I am 40 pounds overweight due to not being to do cardio workouts. I take aspirin daily as a blood thinner. I have considered getting on the keto diet. I drink sweet tea and one dr pepper per day along with coffee and water. I talked to my dr about this diet all he could tell me was he hasn’t researched it enough but knew of someone that lost weight on it. For my health I need to maintain a healthy weight and not be overweight. I have a b12 deficiency along with folic acid. I have not been taking any supplements for either.
