A plant phenolic acid found in grains, berries, peanuts, tomatoes, herbs, and spices; it should not be confused with coumarin or anticoagulant drugs such as warfarin.
A cluster of symptoms in the first days or weeks of low-carbohydrate eating is often related to water and sodium loss, fuel transition, under-eating, sleep and stress. It is not an infection or a required stage, but a signal to check electrolytes, food and safety.
A dangerous state in which ketone bodies accumulate together with a serious acid-base disturbance. It should not be confused with ordinary nutritional ketosis: ketoacidosis requires urgent medical assessment, especially in type 1 diabetes.
The liver’s production of ketone bodies increases when insulin is low, carbohydrates are limited, fasting occurs and fatty acid use rises. It is a normal energy adaptation, but it must be distinguished from ketoacidosis and interpreted in context.
The body’s shift toward using fatty acids and ketone bodies takes time, electrolytes, adequate protein, sleep and gradual training adjustment. It is not just ketones appearing in urine; muscles, liver, brain, water and minerals all adapt.
Amino acids whose carbon skeletons can become acetyl-CoA or acetoacetate can participate in ketone-body-related pathways. This does not mean protein automatically “makes ketones”; amino acid fate depends on tissue needs, energy status and hormones.
A very-low-carbohydrate diet shifts the body toward using fats and ketone bodies, but it requires adequate protein, electrolytes, nutrient density and medication awareness. Therapeutic keto, practical LCHF and trendy sugar-free products are not the same thing.
A calculated way to estimate how strongly a food may support ketone production based on fat, protein and carbohydrate balance. It can be a useful guide, but it does not replace real metabolic response or overall food quality.
Water-soluble energy molecules made by the liver from fatty acids when insulin is low, during fasting or carbohydrate restriction. The main forms are beta-hydroxybutyrate, acetoacetate and acetone, each with different roles and measurement methods.
Urine test strips mainly detect acetoacetate, so they are useful as a simple early keto indicator but do not precisely measure adaptation or fat loss. Color depends on hydration, timing, diet stage and illness; in diabetes, a high result must be read together with glucose, symptoms and medication context.
The presence of ketone bodies in the blood shows that the body is producing and using an alternative fuel from fatty acids. During low-carbohydrate eating it may be a normal adaptation, but in diabetes, infection, vomiting, pregnancy or marked weakness, high ketones must be interpreted together with glucose, symptoms and medication context.
In nutrition and metabolism, ketones usually mean ketone bodies produced by the liver from fatty acids when available glucose is lower. They can be normal fuel during keto, fasting and exercise, but high levels during illness, diabetes or dehydration require careful interpretation.
The presence of ketone bodies in urine can be normal during fasting, low-carbohydrate eating and exercise, but in diabetes with high glucose it becomes an important warning sign. Urine strips mainly reflect acetoacetate and are affected by hydration, so the result must be read with symptoms and context.
A state in which blood ketone bodies rise and the body uses more fat as fuel can be nutritional, fasting-related or illness-related. Nutritional ketosis differs from ketoacidosis by normal pH, adequate insulin and stable wellbeing.
These paired organs regulate water, sodium, potassium, acid-base balance, blood pressure, waste elimination, and vitamin D activation. In low-carb nutrition, hydration, electrolytes, medication effects, blood pressure, and actual kidney function matter more than a blanket fear of protein in healthy people.
