Considering everything said, let’s evaluate the answers to all the queries relating to intermittent fasting and its commonly discussed role in weight loss
What is Intermittent fasting?
The term “intermittent fasting” describes a diet strategy intended to lengthen the time your body remains in a fasted condition. Some short-term scientific studies mainly done on animal models and very few involving humans found it to be quite effective in improving insulin sensitivity, weight loss, antioxidant defenses, and mitochondrial function.
The three main approaches to intermittent fasting are:
- Time-restricted eating restricts your food consumption to a particular number of hours per day (e.g., You could try 16/8 fasting, which involves eating for eight hours and fasting for sixteen).
- The 5:2 diet includes sticking to your usual eating patterns for five days a week and then going on a caloric deficit (500-600 kcal) plan for the remaining two days.
- Alternate day fasting-you eat regular meals one day and fast or consume very few calories the next.
How does intermittent fasting promote weight loss?
When practicing intermittent fasting your body experiences the fed-fast cycle, which is characterized by adjustments to your hormone levels and metabolism.
Following a meal, the fed state sets in as your body begins to process and assimilate the nutrients.
Your body enters the early fasting state 3–4 hours after eating, and it lasts for the next 18–20 hours.
As your blood sugar and insulin levels drop, your body begins converting glycogen into glucose (sugar) for use as energy.
In a completely starved condition, the body uses ketones to maintain proteins in the cells and to meet the energy needs of the brain and other glucose-dependent organs. This cellular signaling promotes cellular repair and recycling mechanisms while decreasing cellular growth pathways.
It is conceivable that fasting may help lower diabetes, high cholesterol, hypertension, and obesity given how much of chronic disease is caused by intrinsic insulin resistance and inflammation.
Now comes the tricky part, as how soon your body enters the phase where it breaks down glycogen or ketone bodies extensively depends on the following three variables:
- Quality of meals consumed during the eating window
- Quantity of meals eaten during the non-fasting time
- The general level of physical exercise you engage in
