How does keto affect weight loss in people with type 2 diabetes?
The keto diet is a low-carb, high-fat eating plan that has been used to manage weight loss and certain medical conditions, including type 2 diabetes. The diet changes the way the body makes energy, shifting it from carbohydrates to fats and causing the body to enter a metabolic state called ketosis. This process of using fat for energy is known as ketosis and is considered safe for most people if managed properly.
For people with type 2 diabetes, the keto diet may offer several benefits. Firstly, it can help improve insulin sensitivity, making the body more responsive to insulin. Additionally, by reducing carbohydrate intake, the keto diet can lower blood sugar spikes after meals and improve glycemic control. This, in turn, can lead to a reduction in diabetes medication, particularly insulin. The keto diet has also been associated with lower hemoglobin A1C levels, which is an important component of type 2 diabetes management.
Several studies have shown that the keto diet can promote weight loss and improve blood glucose levels and insulin production in individuals with type 2 diabetes. A 2013 review reported that a ketogenic diet can lead to more significant improvements in blood sugar control, weight loss, and discontinued insulin requirements than other diets. A 2017 study also found that the keto diet outperformed a conventional, low-fat diabetes diet over 32 weeks in terms of weight loss and A1C levels.
However, it is important to note that the keto diet may not be suitable for everyone with type 2 diabetes. Some people may experience side effects such as "keto flu," which includes symptoms like headaches, vomiting, constipation, and mood swings. Additionally, the restrictive nature of the diet can make it challenging to follow long-term. There are also potential long-term side effects, including an increased risk of nutrient deficiencies, kidney stones, and cardiovascular problems.
Before starting the keto diet, it is crucial for individuals with type 2 diabetes to consult their doctor and dietitian to ensure close supervision and make any necessary adjustments to their diabetes medication. While the keto diet may offer benefits for weight loss and blood sugar management in people with type 2 diabetes, more long-term studies are needed to fully understand its safety and effectiveness.

Does keto help with weight loss in the long term?
The ketogenic diet is a high-fat, moderate-protein, and low-carb diet. It works by lowering insulin levels, producing ketones, and increasing fat burning. There is evidence that ketogenic diets can help with weight loss in the short term, but more research is needed to determine their long-term effects.
Short-term effects of keto on weight loss
Some studies suggest that a ketogenic diet may be more effective for weight loss than a low-fat diet, even when total calorie intake is matched. For example, in one older study, people on a ketogenic diet lost 2.2 times more weight than those on a low-calorie, low-fat diet. Triglyceride and HDL ("good") cholesterol levels also improved. However, both groups reduced their calorie intake by a similar amount, which may have contributed to the weight loss.
Another 2007 study compared a low-carb diet to the Diabetes UK's dietary guidelines and found that the low-carb group lost 15.2 pounds (6.9 kg), while the low-fat group lost only 4.6 pounds (2.1 kg). Over three months, the low-carb diet resulted in three times more weight loss. However, there was no difference in HbA1c, ketone, or lipid levels between the groups, and the low-carb group also decreased their calorie intake.
Other ketogenic diet studies have found that the diet may lead to reductions in appetite and food intake, which can be beneficial for weight loss. Additionally, a ketogenic diet can be effective for weight loss without the need for calorie counting, as it eliminates certain foods and requires tracking total grams of carbs consumed daily.
Long-term effects of keto on weight loss
While the ketogenic diet has been shown to be effective for short-term weight loss, the long-term effects on weight loss are less clear. Most of the studies mentioned above evaluated only the short-term effects of the diet, and additional research is needed to determine its impact on weight loss over the long term. It is also unknown whether weight loss is sustained once a normal diet is resumed.
Furthermore, while a ketogenic diet can lead to a rapid initial weight loss, further weight loss may be difficult to achieve after the first six months. Weight loss induced by a ketogenic diet is also relatively modest and comparable to other dietary interventions such as intermittent fasting and the Mediterranean diet.
Factors to consider with keto for weight loss
It is important to note that individual metabolism, genes, body types, lifestyles, taste buds, and personal preferences differ, and no single diet is suitable for everyone. While a ketogenic diet can be beneficial for people with obesity or a higher risk of developing metabolic syndrome, it may not be suitable for everyone. For example, it is not recommended for people with disorders of fat metabolism, carnitine deficiency, or pyruvate kinase deficiency.
Additionally, there may be some negative effects when first starting the diet, such as "keto flu," which can include poor energy and mental function, increased hunger, sleep issues, nausea, digestive discomfort, and poor exercise performance. More long-term investigation is needed to determine the precise long-term effects of the diet, but there may be a risk of kidney or liver problems. Dehydration is also a risk, so it is important to drink plenty of fluids while following this diet.
Before starting a ketogenic diet, it is recommended to consult with a doctor to ensure it is safe and suitable for the individual. It can also be challenging to stick to a ketogenic diet, and other low-carb diet options, such as carb cycling or a standard low-carb diet, may be better alternatives for some people. Additionally, a ketogenic diet may not be the best option for elite athletes, those wishing to build large amounts of muscle, vegetarians, or vegans.

How does keto affect weight loss in people with type 1 diabetes?
The ketogenic, or keto, diet is a very-low-carb, high-fat diet that has been shown to offer several health benefits. However, the question of whether the keto diet is safe for people with type 1 diabetes does not have a simple yes-or-no answer. Many factors need to be considered.
Diabetic ketoacidosis vs. nutritional ketosis
On a keto diet, you significantly reduce your carb intake to less than 50 grams per day and increase your fat intake instead. This shift in metabolism results in nutritional ketosis, which means your body uses ketones in your blood for energy. Diabetic ketoacidosis is a medical emergency that occurs mostly in people with type 1 diabetes if they don't take insulin. Thus, the main difference between nutritional ketosis and diabetic ketoacidosis is as follows:
- In ketosis, only ketone levels are elevated, allowing your body to use mostly fat for energy.
- In diabetic ketoacidosis, blood sugar and ketone levels are very high, resulting in a critical health state.
May lower blood sugar too much
The keto diet has been shown to significantly lower blood sugar levels in people with type 1 and 2 diabetes. However, some participants experienced episodes of their blood sugar levels falling too low. This can happen if your blood sugar levels drop below 70 mg/dl (3.9 mmol/L) and is likely due to improper insulin dosing. The keto diet raises the risk of your blood sugar levels becoming too low. This could lead to potentially serious complications, such as confusion, dizziness, slurred speech, and loss of consciousness.
May cause unwanted weight loss
Strong evidence suggests that the keto diet can promote weight loss. A number of factors are believed to be responsible, including appetite suppression, food elimination, and higher protein intake. While some people with type 1 diabetes may be interested in losing weight, this is not the goal, or even safe, for everyone. It's important to take this possible side effect into consideration before starting the keto diet.
May require insulin reduction
To control their blood sugar, people with type 1 diabetes use short-acting insulin in varying doses that depend on how high their blood sugar levels are and how many carbs a given meal contains. When drastically reducing your carb intake, such as with the keto diet, blood sugar levels trend much lower, requiring less insulin to manage them. Insulin dosing must be properly adjusted to account for your current blood sugar levels, which will likely be lower after starting the keto diet. If you administer the same amount of insulin as before starting the diet, you may experience hypoglycemia (low blood sugar), a serious side effect.
Who should avoid the keto diet?
Due to potentially negative overall health effects, some people with type 1 diabetes should not follow a keto diet, including:
- Those with a history of chronic low blood sugar levels
- People who are underweight or have an eating disorder
- People undergoing or recovering from a medical procedure
- Children or adolescents under 18 years old
- Pregnant or breastfeeding mothers
- Cholesterol hyper-responders
With proper medical guidance, the keto diet can be a relatively safe option for some people with type 1 diabetes while others should avoid it altogether. It's best to start by trying a lower-carb diet before implementing a full ketogenic diet to see how your body responds. If you have type 1 diabetes and want to try the keto diet, speak to your healthcare provider and a dietitian to set up a personalized program to minimize your risk of potentially dangerous side effects.

How does keto affect weight loss in people with metabolic syndrome?
The ketogenic diet is a high-fat, moderate-protein, and low-carb diet. It works by lowering insulin levels, producing ketones, and increasing fat burning. Research has shown that the diet can be beneficial for people with obesity and can help with weight loss.
Metabolic syndrome is a cluster of metabolic abnormalities, including type 2 diabetes, high blood pressure, high waist-to-hip ratio, and low HDL (good) cholesterol. It refers to five risk factors that increase the likelihood of developing type 2 diabetes, heart disease, and stroke. These are:
- High blood sugar levels, including high fasting glucose levels (insulin resistance)
- High triglyceride levels
- Excess fat in the abdominal area (around the waist)
- Low levels of good HDL cholesterol
- High blood pressure (greater than 130/85 mmHg)
The ketogenic diet can be beneficial for people with metabolic syndrome. It can help to lower insulin levels and improve insulin resistance. Research has shown that the ketogenic diet is more effective at improving factors like triglyceride levels, fasting insulin levels, and metabolic syndrome when compared to a low-fat diet. The diet can also help to reduce calorie intake and increase feelings of fullness.
However, there may be some negative effects of the ketogenic diet. Some people may experience flu-like symptoms when they first start the diet, known as "keto flu". There is also a risk of dehydration, so it is important to drink plenty of fluids. Additionally, the ketogenic diet may not be suitable for everyone, such as people with disorders of fat metabolism, carnitine deficiency, or pyruvate kinase deficiency. It can also be hard to stick to the diet for a long time.
Overall, the ketogenic diet can be an effective way to lose weight and manage metabolic syndrome, but it is important to speak to a doctor before starting the diet to ensure it is safe and suitable for you.

How does keto affect weight loss in people with obesity?
A ketogenic diet is a high-fat, moderate-protein, and low-carb diet. It works by lowering insulin levels, producing ketones, and increasing fat burning. It has been shown to be an effective weight-loss diet that is well-supported by evidence. It is filling and usually does not require calorie counting.
There is evidence that ketogenic diets can help with weight loss in people with obesity. They may help them lose fat, preserve muscle mass, and improve markers of disease. Some studies have suggested that a ketogenic diet may be more effective than a low-fat diet for weight loss, even after matching the total calorie intake. However, more research is needed to determine how the diet may impact weight loss in the long run and whether weight is regained once a normal diet is resumed.
Ketogenic diets promote weight loss by increasing protein intake, converting fat and protein into carbs for fuel, suppressing appetite, improving insulin sensitivity, and decreasing fat storage.
In addition to weight loss, ketogenic diets can also improve many aspects of metabolic syndrome, a major risk factor for obesity, type 2 diabetes, and heart disease. They are extremely effective for lowering insulin levels, especially for people with type 2 diabetes or prediabetes.
Overall, a ketogenic diet can be beneficial for people with obesity, but more research is needed to fully understand its long-term effects.
