Ketosis is a normal metabolic flow or process, when your body continues in a steady working flow. A state in which our system gathers energy from food in order to be burned / turned for energy. As part of this process, it makes ketones.
Commonly is society, this is when it takes energy from carbohydrates but in normality, these carbs also tend to settle in those unwanted areas. When one changes to a low sugar and low carb lifestyle, it now gathers energy saturates from food for your cells to burn for energy, thus it burns fat instead at the same time providing that necessary energy requirement. In short; fat is broken down and ketones are made when one’s diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly (meaning many turn to large doses of carbs and sugar in a need for energy but far too much is not an energy source but rather a buildup of unnecessary bodily fat and weight gain).
For those practicing a healthier lifestyle and those whom don't have diabetes and aren't pregnant, ketosis can kick in around approx 3 or 4 days (or possibly a week to two, dependent on the individual as well but, in normal cases within the week) of eating less than 50 grams of carbohydrates per day and 10 grams of straight sugar per day. One can go into deeper ketosis by going less than 30 grams of carbs per day and less than 5 grams o sugar per day. Only important note here; the deeper one goes into true ketosis, it should be noted those whom go zero sugar and zero (or near to zero) carbs that ketosis can actually be a negative factor and somewhat dangerous / High levels lead to one being dehydrated and change the chemical balance of your blood where it can become far too acidic and lead to Ketoacidosis (believe me, nobody want’s to be in this situation – note to add; this can also occur in some with extreme high blood sugar levels and/or high levels of stress and/or drug abuse). Our systems “do” need healthy carbs to feed our necessities (a whole other topic here of course) so, a zone of 50 to 100 grams/day with very low sugar (straight sugar is not necessary in our lives at all, of course a life ailment is in requirement of ‘some’ (again, another large topic), is very safe and sufficient for moderate state of ketosis as well a very healthy, liveable and manageable lifelong lifestyle and very safe from the danger of a far too deep ketosis state (especially long term).
In addition to helping your burn body fat, ketosis can make you feel less hungry, which in itself is a plus in the battle of weight loss BUT ALSO in daily maintenance. But, in recommendation, a moderate state and feeding ourselves healthy carbs and keeping our sugar intake very low is the proper and safe way to manage and maintain.
Have a Great Day All,
