Before Going Keto, Here Is What You Should Know.
The ketogenic diet has grown in popularity significantly over the past several years. Those who follow this diet report benefits such as rapid weight loss, a greater feeling of fullness, more energy, and improvements in their cognitive abilities. Originally, this diet was designed for people living with seizures. When a person follows this diet, they consume less than 10% of their energy in the form of carbohydrates, 15-20% of their energy in the form of protein, and 75-80% of their energy in the form of fat. This text shows the possible side effects, then some points related to diabetes will be discussed. Possible side effects Positive Rapid weight loss (mostly loss of water, not fat mass); Like any other diet, if there is significant weight loss, for those with type 2 diabetes or with cardiovascular disease, there may be an improvement in the metabolic profile (2); Studies show people assigned to the ketogenic diet have greater weight loss (0.9 kg) than those assigned a low-fat diet after 1 year (3). Negative Increased risk of suffering from kidney stones, malnutrition (nutritional deficiencies), constipation, diarrhea, rash, alterations in lipid profile, weakness, headache, metabolic acidosis (2) and halitosis; Deprivation on many life's pleasures (restaurants, meals with family and friends, etc.). Diabetes To date, the ketogenic diet is not recommended for people with diabetes. No diet had a clinically significant effect on fasting blood sugar (4). In fact, the probability of dropping out is 13% to 84% (3). On the other hand, it has been shown that for patients living with type 2 diabetes and obesity, a diet low in carbohydrates (40% of the total energy consumed), rich in lipids and proteins can improve in the short term (no sustained improvement at 12 months), glycated hemoglobin and triglycerides (5). Medications Since some medications increase the risk of hypoglycemia, some prescriptions need to be adjusted when a person wants to follow the ketogenic diet. This is the case for insulin, sulphonylureas (glibenclamide, gliclazide, glipizide, glimepiride, tolbutamide) and glinides (repaglinide, nateglinide) (6). SGLT2 inhibitors are also contraindicated with the ketogenic diet since they may increase the risk of euglycemic diabetic ketoacidosis (7). Dietitian's Role On the one hand, one must explain the possible side effects. Then the patient can be asked if he can follow this diet for life. If he wishes to do it, we support him by advising him on the best foods to choose while trying to reduce the possible consequences of this diet. Conclusion The best diet is one that we can follow for life, that satisfies us mentally and physically. The ketogenic diet is very restrictive and generally not recommended.
