How Does It Differ From The 1: 8 Method
This plan may sound very similar to the 16:8 intermittent fast with just a smaller feeding window, however, it is actually very different to execute. Heres why:
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.
Is Cycling Better Than Running
The debate of which cardio exercise is better, running or cycling, has been around for a while. Both have their pros and cons, but which one is better for you?
Running is a great cardio workout because it is low impact and can be done anywhere. You dont need any equipment other than a good pair of running shoes. Running also burns more calories than cycling, so it is great for weight loss.
However, running can be hard on your joints and can lead to injuries such as shin splints or a runners knee.
Cycling is also a great cardio workout that has low impact and can be done indoors or outdoors. You do need some equipment, such as a bike, but once you have that, youre good to go. Cycling is easier on your joints than running and there is less chance of injury.
Side Effects Of Intermittent Fasting
Intermittent fasting can have unpleasant side effects. They could include hunger, fatigue, insomnia, irritability, decreased concentration, nausea, constipation and headaches. Most side effects go away within a month.
Sticking with an intermittent fasting routine can be easier for some people rather than trying to watch calories every day. Other people, especially those with busy or variable schedules, have more difficulty maintaining an intermittent fasting routine.

What Are The Different Intermittent Fasting Patterns
Intermittent fasting involves consuming all of your calories within a short period of time. There are many intermittent eating patterns, so its important to choose one thats right for your body, your activity level and your lifestyle. Here are two popular options:
The 16:8 DietThe 16:8 diet involves fasting for 16 hours each day and consuming all of your calories during an 8-hour window. Many people who follow this 16-hour fast eat 2 meals between noon and 8 pm, but you can adjust the 8-hour window to suit your lifestyle, exercise habits and work schedule. With this option, however, plan your eating so that the majority of the fast occurs during your normal sleeping hours. This will help you avoid feeling hungry during your waking hours.
The 5:2 DietAnother popular option is the 5:2 diet, which involves 5 days of normal eating and 2 days of eating around 500-600 calories per day. The 5:2 diet gives you the flexibility to choose the 2 fasting days that work best for you, as long as theyre separated by at least one normal eating day.

Intermittent Fasting: What Is It And Is It The Best Weight
SAN ANTONIO Once the holidays are over, many of us will be trying to lose some weight. More will fail than succeed, but is that because we arent going about it the right way? Here we take a look at a popular trend called intermittent fasting.
Statistics show that 19 out of every 20 people fall short in their dieting efforts, and half of the weight we gain happens during the holidays. If youre looking to shed a few pounds, intermittent fasting may be for you.
So what is it? For that we turn to Brenda Morgan, a personal trainer and owner of the wellness business A Health Warrior. She described the practice of intermittent fasting as not eating at certain times of the day when you choose not to eat, or you can choose certain days that you dont eat.
Morgan claims its more efficient than simply cutting back calories because it gives the body a chance to repair itself.
Dr. Vidhya Illuri, an endocrinologist with the Texas Diabetes Institute within University Health, said the benefits of the weight-loss method come down to the individual.
I think we all have to think about what our motivation is for intermittent fasting, Illuri said, adding that even though it could be a good way to lose weight, other problems could develop. I think a lot of people are doing it for quick weight loss. And I can see that as problematic if it creates disordered eating.
For some it can even become downright dangerous.
If you get into the cycle of fasting and binging, Illuri said.

Fast For 12 Hours A Day
The rules for this diet are simple. A person needs to decide on and adhere to a 12-hour fasting window every day.
According to some researchers, fasting for 1016 hours can cause the body to turn its fat stores into energy, which releases ketones into the bloodstream. This should encourage weight loss.
This type of intermittent fasting plan may be a good option for beginners. This is because the fasting window is relatively small, much of the fasting occurs during sleep, and the person can consume the same number of calories each day.
The easiest way to do the 12-hour fast is to include the period of sleep in the fasting window.
For example, a person could choose to fast between 7 p.m. and 7 a.m. They would need to finish their dinner before 7 p.m. and wait until 7 a.m. to eat breakfast but would be asleep for much of the time in between.
Eating Tips For Intermittent Fasting For Weight Loss:
- Try to eat food rich in fiber during your eating windows like beans, veggies, nuts, etc, and high protein food like tofu, cotton cheese, meat, etc.
- Eat plenty of water, this will not just keep you hydrated but also help in controlling hunger during fast.
- During fasting, you can eat and drink low-calorie drinks and foods such as black coffee, tea, and vegetables.
- Avoid artificially flavored drinks as these are not good for controlling your appetite and even bad for health. Soda, soft drinks, flavored milk, etc are all belongs to the same category.

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 youre 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 werent fasting. But the weight loss didnt last over time.

Caloric Restriction Versus Fasting
Caloric restriction means eating less all the time, whereas fasting means eating less, sometimes.
With caloric restriction, instead of consuming, say, 2000 calories per day, one would consume 25 percent or even 30 percent fewer calories per day. Caloric restriction has shown to extend lifespan and reduce the risk of many aging-related diseases .
However, its not easy to continuously eat less, and to do so for years or even the rest of your life. Some people believe you will always feel hungry, but this is also somewhat relative: after a while many people get used to it.
In fact, caloric restriction does not have to be that difficult. A simple way to eat less is just by eating two meals per day. Not only will this save you some money, but a lot of time, too !
While caloric restriction means restricting calories throughout the day, fasting means going without food for specific periods.
Often, the boundaries between caloric restriction and fasting are somewhat blurry. After all, if you fast regularly then youre also likely to restrict calories overall.
How To Successfully Do The : 4 Intermittent Fast
The Warrior Diet plan involves fasting for 20 hours during the day followed by overeating in a 4-hour window at night.
For example, you may set your feeding window at 6:00 pm to 10:00 pm. During this time you can eat as much as you want with an emphasis on unprocessed, organic whole foods particularly those high in dietary fats and protein.
After 10:00 pm, you fast or eat very small portions of specific foods such as raw fruit and vegetables until 6:00 pm the next day. Its important youre eating as fewer calories as possible during this time.
The method is best suited for people who have tried intermittent fasting before or who already consume a low-carb/ketogenic diet.
Hofmekler recommends you follow a three-week, three-phase plan initially before starting the Warrior Diet. This helps the body adapt to the eating and fasting schedule and become accustomed to using body fat as energy. This three-week introduction includes:
Once you have completed the three-phase diet, it is recommended you start it again before following the 20:4 guidelines.
