Intermittent fasting is a well-known, science-backed way to lose weight by alternating the cycle of eating and fasting and changing the metabolic state. It is considered one of the most beneficial fasting and works in different stages, depending on the number of hours you spend without food, and its results appear, according to what was published by the “Times of India” website, we explain to you What really happens once you start intermittent fasting and how the different phases affect weight loss.
The first stage: feeding
The state of "nutrition" begins a few hours after you eat food. This is the stage where food begins to be digested and nutrients are absorbed and transported. This usually occurs 2-3 hours after eating.
Initially, blood sugar levels rise and insulin secretion increases, depending on the type of meal you ate and the extra sugar is converted into glycogen, which the body uses as an energy source when needed (when food is not available).
This is the stage where other important hormones are managed, including ghrelin and leptin (the hunger hormones), and depending on the type and amount of food you eat, your body tends to stay in a nourished state for hours.
The second stage: the state of early fasting
The pre-fasting state begins 3-4 hours after you stop eating, and tends to last up to 18 hours. It is also referred to as a transitional state when the body switches to using 'extra' stored glucose (glycogen) as fuel.
Slowly, after the sources of glycogen are depleted, the body begins to break down amino acids (proteins) and triglycerides to use them as energy sources and carry out vital functions. This is the primary way intermittent fasting works, and some of the more popular ways to do intermittent fasting, such as the 16:8 method that alternates Among the cases of early fasting.
The third stage: the state of fasting
The "fasting" state is an extension of the pre-fasting state and can occur between 18 hours and two days of fasting. During this state, glycogen storage is depleted and amino acids and other fat sources are broken down as well, which then triggers production of ketones, a compound produced when the body converts Fats for fuel, forcing the body into a ketogenic state, extracting primary energy from fats and not carbohydrates.
At this stage, initial signs such as a change in breathing, decreased appetite, fatigue, and rarely a decrease in body weight can occur at this stage.
Fourth stage: state of hunger
The state of starvation follows long hours of fasting, most of the time 48 hours after a reduction in food intake. Muscles from collapsing.
