Fasting is an ancient practice that is often associated with religions over the ages. Fasting gives our body time to rest and heal.
Intermittent fasting (IF) is today one of the most popular fitness
and health trends in the world.
People use it to lose weight, improve health and make their
lifestyles simpler.
Studies show that it can have potent effects on your body and
brain and may even help increase longevity.
Here, is the ultimate beginners guide for beginners to intermittent
fasting.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern where you follow a cycle
of feeding and fasting.
It doesn't say what foods to eat but WHEN you should eat them.
There are several different intermittent fasting methods, all
dividing the day or week into eating times and fasting periods.
Every day, most of the people are already fasting while they sleep.
By extending this fast a little bit longer you can easily do intermittent
fasting.
It can be done by skipping breakfast or eating your first meal at
noon and your last meal by 8 pm.
If you are someone whole wakes up early in the morning, then you
can shift this window as per your preference.
By doing this, ideally, you are fasting for 16 hours a day, and
that is the 16/8 method of intermittent fasting.
You may think now that its difficult to do but many people have
reported feeling better and more energetic during the fast. Hunger can be an
issue in the beginning but give your body some time to get used to the change. After all, it takes some time to build a habit and get accustomed to it.
Methods of Intermittent Fasting
Different methods of intermittent fasting require splitting the
day or week into eating and fasting periods.
During the periods of fasting, you either eat very little or
nothing at all.
Here are the most popular methods:
- The 16/8 Method: or Leangains protocol involves skipping breakfast or eating your first meal at noon and your last meal by 8 pm. If you are someone whole wakes up early in the morning, then you can shift this window as per your preference. By doing this, ideally, you are fasting for 16 hours a day, and that is 16/8 method of intermittent fasting.
- The 19/5 Method: 19/5 Fasting limits the eating period to five hours, just a little more. This method allows 2 meals a day.
- The 5:2 Diet: On two non-consecutive days of the week you consume only 500–600 calories but normally eat the other 5 days.
- Alternate Day Fasting (ADF): Many people fast more than once a week for 24–36 hours, in a practice, called alternate-day fasting. Under this system, people are fasting every other day, so their diet is unrestricted on eating days. The eating period is most usually 24 hours, meaning that people eat a small dinner on fasting days just before bedtime.
If you are a beginner, don’t worry start at your own pace and
listen to your body.
How IF Affects Your Body: Cells and Hormones
When you fast, your body undergoes several changes at cellular and
hormonal levels. Your body adjusts the hormone levels to increase the accessibility
of stored body fat.
Also, your cells initiate important processes of repairing and
change gene expression.
Here is a list of changes that occur in your body when you fast:
- Human Growth Hormone (HGH): Skyrocket growth
hormone levels, rising as much as 5-fold. This has benefits for fat loss and
muscle development.
- Insulin: The sensitivity to insulin improves,
and insulin levels drop dramatically. Lower insulin levels improve the accessibility of stored body fat.
- Cellular repair: Cellular repair processes are
initiated by your cells when fasted. This includes autophagy, in which cells
digest and extract old and damaged proteins that form within cells.
- Gene expression: Gene function changes related
to longevity and disease defense.
These changes are responsible for the benefits of intermittent fasting.
Powerful Tool for Weight Loss
People are opting for intermittent fasting mainly for weight loss.
As you are eating fewer meals, intermittent fasting automatically results in
reduced calorie intake.
As mentioned above, due to the changes in hormonal level it
facilitates weight loss.
This increases the release of the fat-burning hormone
norepinephrine (noradrenaline) in addition to reducing insulin and rising
growth hormone levels.
Studies have shown that due to the changes in hormone level, short
term fasting may increase your metabolic rate by 3.6-14%.
However, the key explanation for their popularity is that
intermittent fasting lets you consume fewer total calories. If you binge during
eating cycles and eat huge quantities, you may not lose any weight at all.
The Science and Health Benefits of Intermittent Fasting (IF)
Studies have shown that it can have powerful benefits to your body
and brain for weight control and health. It can also help you carry on living
longer.
Here are the main benefits of intermittent fasting:
- Weight Loss: intermittent fasting, as
described above, will help you lose weight and fat in your belly without consciously
restricting calories
- Resistance to Insulin: intermittent fasting
can minimize insulin resistance, decrease blood sugar by 3–6 percent, and fasting
insulin levels by 20–31 percent, which will protect against type 2 diabetes.
- Heart Health: Intermittent fasting can reduce
"bad" LDL cholesterol, triglycerides in the blood, inflammatory
markers, blood sugar, and insulin resistance — all risk factors for heart
disease.
- Cancer: Research on animals indicate
intermittent fasting can prevent cancer.
- Brain Health: Intermittent fasting increases brain
hormone BDNF which can help in the growth of new nerve cells. This can also help prevent
Alzheimer's disease.
Safety Measures
If you have a medical condition, then consult with your doctor
before trying intermittent fasting.
- Have diabetes or irregular blood sugar level.
- Have low blood pressure.
- Taking medications.
- Are underweight (You must read - 20 Best Healthy Foods to Gain Weight)
- A woman who is trying to conceive. (You must read - Diet and Nutrition Tips for Women)
- A woman with a history of amenorrhea.
- Are pregnant or breastfeeding.
Intermittent fasting has an excellent safety profile. If you are
healthy and well-nourished overall there is nothing dangerous about not eating
for a while.
Take Away!!
Should You Try it?
Intermittent fasting is a lifestyle strategy to improve your
health. Eating real food, exercising, and taking an adequate amount of sleep are
some of the most important factors to consider.
If in the beginning, you are facing issues, then try for 1-day
fasting and other day eating normally, or you can also increase the eating
window to 14/10 (14 hours of fasting and 10 hours of eating.
Listen to your body and try it once... if it works for you then great!
For some people intermittent fasting is perfect. The only way you
can find out which party you belong to is to try it once.
If you feel good at fasting and consider it a healthy way to eat,
it can be a very useful tool for weight loss and health improvement.
