How Does Intermittent Fasting Work
There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.
Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.
Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.
Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.

While 5:2 fasting has some clear potential benefits for weight loss and blood sugar control, it also has some downsides. Restricting your intake to 500 to 600 calories two days a week isn’t right for everyone. If you have a history of an eating disorder, are taking medications or have a condition like diabetes, heart or kidney disease, struggle with hypoglycemia or are pregnant or breastfeeding, the 5:2 diet may not be appropriate. It’s always important to check with your doctor before beginning 5:2 fasting or any type of fasting diet.
The 5:2 fasting plan is flexible in that it doesn’t require calorie or macro counting, but it does limit your calories two days a week. Depending on your work schedule or personal obligations, capping your food intake can be difficult. Plan ahead for days where you have big events, like a wedding to attend or an important presentation at work. Aim to fast on days with less going on.

May Improve Insulin And Leptin Sensitivity
Leptin is a hormone that tells your body to stop eating, and insulin is what helps the glucose get into your cells during fasting . The idea behind water fasting is that you are tricking the body into burning fat stores because there isnt any sugar available for it to use as fuel.
This will result in your body being more sensitive to leptin and insulin. Being more insulin sensitive means your body is more efficient at reducing its blood sugar levels. Meanwhile, being more leptin sensitive could help your body process hunger signals more efficiently, and in turn, lower your risk of obesity.;
Can You Exercise On : 2 Diet
You can still exercise on the 5:2 diet meal plan too and in fact, you should. Exercising on 500 calories a day might sound daunting, but it can speed up weight loss and improve overall health and fitness. Some people even find that exercise alleviates hunger pangs.
Research shows fasting has no negative effects on the ability to do moderate activity. Even so, its important to listen to your body. Also, doing cardio can help your body tap into its fat stores, and maximise the benefit of your fasting days.
High-intensity interval training could be your best choice , as short bursts of intense exercise have been shown to be hugely effective, with the fat burning lasting for hours after the workout is finished. HIIT can be as simple as sprinting in short spurts while jogging. And try saving some calories until after your workout.

So Is Intermittent Fasting As Good As It Sounds
I was very curious about this, so I asked the opinion of metabolic expert Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School. Here is what she told me. “There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally she recommends that people “use an eating approach that works for them and is sustainable to them.”
So, heres the deal. There is some good scientific evidence suggesting that circadian rhythm fasting, when combined with a healthy diet and lifestyle, can be a particularly effective approach to weight loss, especially for people at risk for diabetes.

The Backstory On Intermittent Fasting
IF as a weight loss approach has been around in various forms for ages, but was highly popularized in 2012 by BBC broadcast journalist Dr. Michael Mosleys TV documentary;Eat Fast, Live Longer;and book;The Fast Diet, followed by journalist Kate Harrisons book;The 5:2 Diet;based on her own experience, and subsequently by Dr. Jason Fungs 2016 bestseller;The Obesity Code. IF generated a steady positive buzz as anecdotes of its effectiveness proliferated.
As a lifestyle-leaning research doctor, I needed to understand the science. The;Obesity Code;seemed the most evidence-based summary resource, and I loved it. Fung successfully combines plenty of research, his clinical experience, and sensible nutrition advice, and also addresses the socioeconomic forces conspiring to make us fat. He is very clear that we should eat more fruits and veggies, fiber, healthy protein, and fats, and avoid sugar, refined grains, processed foods, and for Gods sake, stop snacking. Check, check, check, I agree. The only part that was still questionable in my mind was the intermittent fasting part.

Why Fasting For Weight Loss Can Backfire
When you eat less than you need and you lose weight, your body goes into a starvation mode. To save energy, your metabolism slows down.
When you’re done fasting and you go back to your usual diet, you may regain the weight you lost, and then some.
On a fast, your body adjusts by curbing your appetite, so you will feel less hungry at first. But once you have stopped fasting, your appetite revs back up. You may feel hungrier and be more likely to overeat.
Fasting every other day has similar results. It helps people lose weight, but not for long.
In one study, people who fasted every other day shed weight, even when they ate all they wanted on days when they weren’t fasting. But the weight loss didn’t last over time.
How One Man Lost 50 Pounds Using The : 2 Intermittent Fasting Diet
Fasting may seem like a drastic way to lose weight, but it can be safe and effective when done in moderation, according to self-improvement blogger Dave Wentworth.
The mechanical engineer, who lives in Michigan, decided to try the 5:2 intermittent fasting diet after joining a weight-loss competition at his job in 2011. Simply put, the diet required him to eat normally five days a week and fast for two.
In simple terms, its eating as normally as you can for five days of the week and then on two days for two 24-hour periods you dont eat, Wentworth tells NBC News BETTER.
That doesnt mean you starve yourself for two days, Wentworth explains. It means that for two non-consecutive days of the week, you eat only one meal. On fasting days, for example, he skipped breakfast and lunch, and only ate dinner.
Its a simple way to get basically a 20 percent reduction in total calories overall, says the engineer.
Heres the breakdown of Wentworths diet:
- Monday: Eat normal
- Tuesday: Fasting day
- Wednesday: Eat normal
- Sunday: Eat normal
Wentworth says the diet worked because it allowed him to be flexible.
Its a simple way to get basically a 20 percent reduction in total calories overall.

Big Metabolic Changes Kick Start On Day 3
My metabolism switched from glucose to ketones by the end of the 3rd day, which fits with what is generally expected based on the standard biochemistry literature.
On typical non-fasting days Ill hit between 1 and 2 mmol/L ketones because I eat a reasonably high fat diet. It wasnt till day 3 till I broke the 2 mmol/L threshold and went beyond, eventually peaking at nearly 7 mmol/L blood ketones. At the same time my blood glucose hit a stable low of just under 60mg/dL.
Overall, I felt less mentally sharp and found the fast hardest between the end of day 1 till around beginning of day 3. Is this harder part of the fast a rough period of adaptation to using ketone and fatty acids as the main fuel source? Perhaps. In my case the switch in the blood results follows closely the ease of the experience for me once blood ketones and glucose inverted the experience was easier.
Seyfried recommends the use of a Glucose-Ketone Index for monitoring the therapeutic value of the fast against cancer. The goal is to have your value of this index below 1 which is considered the therapeutic zone.
67 hours into the fast my index dove below 1, and it bottomed out around 90 hours, from then on hovering between 0.5 to 0.6. So I was in the therapeutic zone for all of days 4 and 5.
Lagging Metabolism Adjustment at End of Fast
When I hit the 120 hour mark I dug into a couple of big bowls of bone broth. Quickly full and satisfied seemingly as if the fast had never taken place.
