How Does Intermittent Fasting Works
When you eat, your body releases insulin after consuming a certain amount of calories, and this insulin release makes you store fat for later use.
When you go without food for many hours, the body exhausts its sugar stores and starts burning fat called metabolic switching.
This is one of the reasons that most people who are intermittent fasters tend to see weight loss quickly. That is why, IF is known to be the best fasting diet for weight loss.
Whats good than that? Youll burn off excess body fat, and you can still eat food!
Intermittent fasting increases the duration of time when your body burns through your last consumed calories and begins burning fat.
Do You Think Intermittent Fasting Is Right For You Now That You Know How To Implement Intermittent Fasting Into Your Life As A Woman Over 40 Its Time To Decide If You Want To
To implement intermittent fasting into your life as a woman over 40, the eating plan must mesh with your lifestyle. If you regularly eat out socially for breakfast early in the morning or dinner later in the evening, aiming to fast during these hours is not sustainable.
There are several ways to approach intermittent fasting. Starting out with a 12 hour fast is a good method to begin with.
A popular method is the 16:8 method because it allows women who have a busy schedule to keep up with the demands of their family life, job, and having an active lifestyle. If you have been wondering if IF will be worth your time, there have been several studies that show that it is a safe and viable method to losing weight and offer many health benefits.
Always talk with your doctor before beginning any IF diet and talk with a dietitian to determine the best way to implement it. An interesting diet structure to combine with IF is the keto diet as they both utilize ketones for energy.
Using intermittent fasting can help you reach ketosis faster. Always eat healthy foods and stay away from processed and fast food options, this much is true for any diet or eating pattern. Consider the benefits and the risks to determine if IF is right for you.

Schedule #: Fasting For 12
Near the end of our year-long coaching program, we offer clients a fasting experiment:
Go a full 24 hours without eating.
Its scary, and it makes people uncomfortable. Which is exactly why we do it.
What it involves
There are no rules or protocols. For instance, people can wake up, have breakfast, then not eat again until breakfast the next day. Or they can have dinner on a Monday, then not eat again until dinner on Tuesday. Or whatever suits them.
The point is to simply try the experience of not eating for a while, and see what happens.
Afterwards, eat normally.
People who benefit
A one-day fast can be transformative for anyone who associates the sensation of hunger with emergency. That tends to include people who learned from their parents that they should eat three square meals a day, as well as finish everything on their plate.
Its also great for people who fear being deprived or restricted, assuming that once they start getting hungry, its going to get worse, and worse, and worse .
And finally, its a great first step that allows you to test the waters, seeing if a more extreme fasting schedulesuch once- or twice-weekly fastingmight work for them.
If you try it
When Should I Exercise
When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
That being said, exercise before you eat because people get hungry about half an hour after they finish working out and may find it too hard to stick to their plan if they cant eat anything at all afterwards, Varady noted.
If youre on the 16:8 plan, exercise before or during your eating window. If youre doing alternate day fasting and are exercising on your 500-calorie day, save food for after your exercise session.

Who Shouldnt Try Intermittent Fasting
Not everyone should try IF. A few groups who shouldnt: women who are pregnant or trying to become pregnant , those taking diabetes medication , or anyone on multiple drugs , says Kumar. Also, if you have a history of eating disorders, introducing periods where youre not allowed to eat can put you on a dangerous path to a relapse.
Know that IF has some side effects. You may be cranky hanger is real during fasting periods because low blood sugar can mess with your mood. You also still need to have a healthy diet when you do eat. One thought is that it would be difficult to make up a calorie deficit if you fasted for two days, but in our society with access to calorie-dense items, you could probably do it, says Kumar. Focus on balanced, nutrient-packed choices, like fruits, vegetables, lean meats, legumes, and whole grains . Expect that for the first couple of weeks you may deal with lower energy, bloating, and cravings until your body adjusts, says Shemek.
Can I Exercise While Fasting And When Is The Best Timing
Yes! Its generally safe to exercise while fasted. However, talk to your physician if you have diabetes or have experienced hypoglycemia during or after fasted exercise.
People practicing alternate day fasting choose to exercise on fasted days as often as on their feeding days. However, when approaching the end of a long fast you may want to stick to light to moderate physical activity.
There arent necessarily best practices for exercise timing with fasting. However, theres evidence that fasted exercise can send you into deeper ketosis more quickly. Light exercise right before or after you eat can also help your body soak up glucose more quickly. High intensity exercise can even raise your blood glucose levels temporarily as your muscles release glycogen and your liver produces new glucose, which could leave you feeling uplifted during a prolonged fast. There are many ways to combine fasting with exercise. Learn more here.

How To Lose Weight By Fasting: The 1: 8 Diet
The 16:8 diet is one of the most popular ways of intermittent fasting. Its extremely simple: for 16 hours you fast, avoiding food and any calorie-containing beverages, and then once those 16 hours are up, you eat your meals within a specific eight-hour eating window.
The great thing about this method is that you can choose any eight-hour window that suits your lifestyle. Plus, your 16 hours of non-eating can incorporate sleep time. For example, you could stop eating at 8pm and wait until noon the next day to open your eating window again. Or if you prefer an earlier breakfast you could opt for a 9am to 5pm eating schedule.
A downside of the 16:8 diet is that it may take your body some time to adjust to eating more meals within a shorter time frame. One workaround is to limit your eating to two meals a day, but initially, you may wish to start with three meals spread out over the course of the eight hours.
Research from the journal Nutrients suggests that intermittent fasting methods like the 16:8 diet can help lower high blood pressure, reduce the amount of food consumed and ultimately lead to weight loss. And for those worried about losing muscle, the 16:8 diet can help maintain muscle mass and prevent muscle loss when combined with resistance training, according to studies in the Journal of Translational Medicine and the American Journal of Clinical Nutrition .
Pros Of Intermittent Fasting

How Effective Is Intermittent Fasting
The effects of intermittent fasting are well known. As stated by the American Heart Association, intermittent fasting can induce weight loss, lower insulin resistance, and chances of cardiovascular disorders are also reduced.
This method of weight loss has been found to be efficient in decreasing the risks of disorders associated with diet. Other disorders may include obesity, hypertension, insulin resistance, dyslipidemia, and inflammation. A longer life expectancy is a benefit of regular fasting.
How Does It Work Does It Prolong Life
A fasted state rings physiological alarm bells to body systems. It sets in motion three important processes: maintenance and repair, consolidating security and switches on the survival mode. The body stops using sugar as fuel and instead starts consuming an acid called ketone bodies. When fasting is intermittent or prolonged but provision of essential nutrients is ensured, body systems become better protected and survival is enhanced. Studies in animals show that fasting prolongs life. Indeed, among so many potential options, this may be the only way to prolong life.
Unlike research in animals, whose lifespan is limited hence permitting survival studies, it is impossible to do so in humans. Hence, we look towards other benefits which could be studied over a short time weight loss, decrease in blood sugar and so on. These processes have been studied using three fasting regimens, alternate day fasting, 5:2 fasting and time restricted eating . Results are mostly good in human studies. Body weight, body fat, blood pressure and cholesterol decreases. Weight loss over 6-12 months ranges from 3-10 per cent. Patients with diabetes improve their blood glucose profile. Fat from organs gets dissolved, thus enabling better functional state. Finally, there is some experimental data to show that it may increase memory and delay onset of Alzheimers disease.
