keto flu
According to Harvard Medical School, ketoacidosis is a common symptom in the first week of this diet. People who eat can face headaches, fatigue, irritability, constipation and even insomnia.
Sudden carbohydrate deficiency causes dehydration and electrolyte imbalance, says Dr. Marcelo Campos, lecturer at Harvard Medical School and Tufts University School of Medicine. This is like putting the body in a state of fighting for survival.
Lack of fiber
The keto diet eliminates almost all grains and fruits, which are an important source of fiber. According to a study in the journal Science, fiber helps nourish gut bacteria, creating short-chain fatty acids, substances that have anti-inflammatory and regulating blood sugar properties.
Lack of fiber not only affects digestion but also increases the risk of colon cancer, the warning was given in an overview article in The BMJ. A unbalanced diet can easily damage the gut microbiome, leading to a series of health consequences, says Dr. Walter Willett, a nutritionist at Harvard University.
Reduced sports performance
A study in the Journal of Sports Medicine and Physical Fitness found that short-term keto regimens reduce performance in activities that require high endurance. Lack of carbohydrates depletes the energy quickly, causing athletes to quickly exhaust themselves.
Risk of ketone acidosis
keto diet can cause ketone acidosis - a serious condition commonly found in people with type 1 diabetes. A study published in the Journal of Medical Case Reports warns: People who are breastfeeding or have underlying medical conditions need to be especially careful, because keto can trigger life-threatening acidosis.
higher risk of death from cardiovascular disease and cancer
At the European Cardiovascular Congress, researchers from the University of Lodz (Poland) published research showing that keto dieters, meaning a low-carb diet, are significantly more likely to die from cardiovascular disease and cancer than people on a balanced diet.
