The subjects had a mean BMI of 42.2, mean age of 56 years, and were of either African-American or Caucasian descent. In their intervention, subjects consumed a LCKD diet with the goal of eating less than 20 grams of carbohydrates per day while reducing dosages of diabetes medication. Subjects also received nutritional counseling and medication adjustment every two weeks.
On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids. Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.
You have about 160,000 Kcals of fat available to burn – producing your own glucose in the process when needed (for anaerobic bursts). In contrast you only store around 400 to 500 Kcals of glucose/glycogen ready for use so if you are not adapted to burning fat then you are physically dependent and addicted to eating carbs. When you hear of a runner “hitting the wall” it’s only because of their unnatural carb addiction – an efficient fat burning athlete can run all day and will never have this problem. The human body is specifically designed to run long distance and can outrun almost every other animal on this planet – we can even run though intense heat because we sweat.
Some antidepressant medications can cause weight gain, especially the older tricyclic antidepressants (TCAs) such as Tryptizol, Saroten, and Clomipramine; as well as newer drugs such as Remeron (Mirtazapine). Lithium (for manic-depressive disorder) often causes weight gain. The most common antidepressants known as SSRI’s (for example Citalopram and Sertraline) usually don’t impact weight significantly.

You are so biased against Keto, this can be noticed very quickly because almost every positive thing you say about Keto, you immediately follow with a “but…” negative statement. And most of your negatives are simply saying it’s hard to maintain. You completely exaggerate the negatives “If you have one bad day and your body is kicked out of Ketosis, you immediately gain all of your weight back”. That is simply not true; if someone is on a Keto diet for 3 months, they will not gain that weight back in a day. Also, their body will be back into Ketosis the next morning. You say that the ADA doesn’t recommend 60-70 grams per meal, but it does (coincidentally I just left their website before coming here). I don’t claim to be a Diabetes expert; I admit that. But your bias is leaning heavily against Keto. “Moderation” is not your goal if you have diabetes. When you compare HbA1C levels, for example, you compare them with someone in Keto at less than 20 g of Carbs per day as compared to someone at a 70-90 gram of carbs per day diet. You should be fair and compare them with someone on a 200 g of Carbs diet. If you want to get rid of the effects of Diabetes, get on a Keto Diet, period. It MAY get rid of the effects completely, but in the very least it WILL reduce your Insulin needs to very low and you’ll have little-to-no side effects other than a relatively restrictive diet (most diets are WAY more restrictive than Keto). You back up everything with “science” and misleading numbers/arguments without providing any real evidence.
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
The following measurements were made every other week: anthropometric and vital sign measurements; urine testing for ketones; and assessment for hypoglycemic episodes and other symptomatic side effects. Weight was measured on a standardized digital scale while the participant was wearing light clothes and shoes were removed. Skinfold thickness was measured at 4 sites – the average of 2 measurements at each site was entered into an equation to calculate percent body fat . Waist circumference was measured at the midpoint between the inferior rib and the iliac crest using an inelastic tape; 2 measurements were averaged in the analysis. Blood pressure and heart rate were measured after the participant had been seated quietly without talking for 3 minutes. Certified laboratory technicians assessed urine ketones from a fresh specimen using the following semi-quantitative scale: none, trace (up to 0.9 mmol/L [5 mg/dL]), small (0.9–6.9 mmol/L [5–40 mg/dL]), moderate (6.9–13.8 mmol/L [40–80 mg/dL]), large80 (13.8–27.5 mmol/L [80–160 mg/dL]), large160 (>27.5 mmol/L [160 mg/dL]). Hypoglycemic episodes and symptomatic side effects were assessed by direct questioning of the participant and by self-administered questionnaires.
The ketogenic diet has the potential to decrease blood glucose levels. Managing carbohydrate intake is often recommended for people with type 2 diabetes because carbohydrates turn to sugar and, in large quantities, can cause blood sugar spikes. If you already have high blood glucose, then eating too many carbs can be dangerous. By switching the focus to fat, some people experience reduced blood sugar.
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger portion sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant. The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of avocado oil daily lost nearly two percent of their belly fat in just one month.
From an outpatient clinic, we recruited 28 overweight participants with type 2 diabetes for a 16-week single-arm pilot diet intervention trial. We provided LCKD counseling, with an initial goal of <20 g carbohydrate/day, while reducing diabetes medication dosages at diet initiation. Participants returned every other week for measurements, counseling, and further medication adjustment. The primary outcome was hemoglobin A1c.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
