Ketosis is the process where your body converts carbohydrates into energy. When you are fasting or eating very low carb diets, it’s possible to go without food for long periods of time and still maintain good health. However, if you’re trying to lose weight while following such a diet, then your body will eventually begin using up all its stored fat stores (the kind that don’t come from exercise) in order to provide enough fuel for your brain and other vital organs. If you do not consume any carbs during these times, your body will turn to fatty acids for energy instead. Fatty acid metabolism is known to be more efficient than carbohydrate metabolism, so the result is that you burn through less fat stores over time.
The problem with this approach is that it doesn’t work well when combined with high amounts of protein intake (which also causes ketones production). So, you need to combine the two approaches in order to get maximum benefits.
A ketogenic diet is one that involves restricting carbohydrate consumption in favor of fats and proteins. The idea behind this type of diet is that it will cause your body to convert dietary carbohydrates into ketone bodies which are used for energy rather than being stored as fat. These ketones can then be burned off by your liver, muscles, heart and other tissues when needed. This is known as metabolic flexibility or mitochondrial flexibility.
Other studies have shown great benefits of combining a regular aerobic exercise routine with a ketogenic diet. There is also evidence to suggest that a regular short term fast which is what we are doing here, not something to undertake regularly but more of a short sharp shock to the system to kick start the ketosis process. Lastly, the other variables of good health include stress management, getting enough sleep, exercise and playing a variety of bodily systems.
It’s also important to note that not all exercise is equally effective when it comes to boosting your metabolism. The best results come from interval training, where you switch back and forth between higher levels of activity and periods of complete rest. Rather than walking at a steady pace on a treadmill, run for a few minutes, then walk for a few minutes to recover.
There is very little risk to a healthy person of doing a 3 day fast. If you are worried about it, you can always talk to your doctor and he can confirm that there should be no issues as long as you don’t have some rare allergy that we don’t know about, or are not already in a debilitated state.
Ketosis occurs mainly in times of low glucose availability.
