When Will Ketosis Start

Ketosis: What Is Ketosis?

Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to av Continue reading >>

    Experienced fasters: How long does it take you to reach ketosis?

    It seems that it takes about 3 days for the average person to get into a state of ketosis when fasting.
    For those of you who are veterans of fasting, especially longer fasts (5+ days), how long does it take you to get into ketosis?
    I'm curious about this due to this guy going into ketosis in only 2 days on his second 5 day fast. Was wondering if it was due to the avocado or his body just adapting faster.

    You should be in ketosis once your liver glycogen stores are depleted. In a fast this should occur in 24-48hrs after your last meal and will be influenced by your insulin sensitivity (which affects you basal insulin level) and the amount of glycogen in your liver (ie what you ate leading up to the fast). It's entirely possible (some would argue desirable) to be in ketosis before fasting. Nutritional ketosis generally starts when you have a betahydroxybuterate level greater than .5 mmol/L which can't be accurately measured through urine ketostix which only show excreted acetoacetate (not blood concentrations of BHB). You can turn those keto sticks dark purple just by restricting fluid intake and becoming slightly dehydrated or equally make them not register by drinking half a gallon of water.
    Ketosis is brought on by a lack of carbohydrates/insulin and not by the presence of fat.
    Eat under 20g of net carbs per day (don't count fibre) for 3 days and you will be in ketosis. You will probably be in ketosis sooner, but 3 days is pretty true for everyone.
    Remember that as you produce ketones you will start to use them as well as free fatty acids for fuel (less is excreted in urine and blood levels don't increase indefinitely). In the end ketones will be used primarily for your brain and other tissues not able to use FFA while glucose will be reserved for cells that can only use glucose (eg red blood cells and some parts of the brain). The breakdown of triglycerides into FFAs also releases glycerol that is converted into glucose to supply the now reduced demand for glucose. This doesn't happen as soon as you produce ketones but over a few days as your levels increase.
    Edit: nutritional ketosis defined as starting at .5 rather than .3 mmol/l

    this should occur in 24-48hrs after your last meal
    Actually in the link I posted it took 3 days initially for the guy to go into ketosis, then on the second time through it only took him 2. I'm very interested in to why this was as I am planning on doing a series of longer fasts and want to make it as easy as possible.
    and will be influenced by your insulin sensitivity
    So perhaps the reason why the 2nd fast was quicker to get into ketosis with due to increased insulin sensitivity from his initial fast?
    and the amount of glycogen in your liver (ie what you ate leading up to the fast).
    This is my current plan: eat under 20g carbs for two days, start water fasting on the third and lifting heavy squats and dead lifts; then taking apple cider vinegar before bed.
