Ketosis: What is the Best Ketone Range for Fat Loss- Thomas DeLauer…
Ketone Ranges Overview:
-Below 0.5 mmol/L is not considered ketosis
-Between 0.5-1.5 mmol/L is light nutritional ketosis
-Around 1.5 – 3 mmol/L is optimal ketosis and is ideal for fat loss
-Over 3 mmol/L do not mean better or worse results than being at the 1.5-3 level
-Between 0.5 & 3 mmol/L

**Nutritional Ketosis = 1.5-3 mmol/L, which is the optimal range for fat burning**
-Ketones in the 1-3 mmol/l range are not acidifying the body
-Over 3 mmol/L

Because ketones are acid substances, high ketone concentrations in the blood may create acidosis. Ketoacidosis, commonly referred to diabetic ketoacidosis, is a very dangerous state where an individual with uncontrolled diabetes is effectively starving due to lack of insulin. In normal individuals, or those with well controlled diabetes, insulin acts to cancel the feedback loop and slow and stop the overproduction of ketones (insulin has a suppressant effect on ketone production.) Without this feedback loop, dangerous levels of ketones build up, acidifying the body. The levels can build up to a state that is highly toxic. If someone is in this state, they are usually accompanied with excessive thirst and urination, hyperglycemia, pain, nausea, and deep, labored, gasping breathing (2)
