How Intermittent Fasting Can Help You Lose Weight

Intermittent fasting sounds pretty daunting, but it has been all the rage for the past few years now. Fasting has been practiced during many religious ceremonies for centuries, so it is nothing new. Today intermittent fasting, otherwise known as IF is trending within the health and wellness world, specifically amongst some weight loss gurus. Intermittent fasting is practiced by many for a host of health benefits and involves cycles of not eating food or a limited amount of food for several hours, sometimes days.

Fasting Varies For Everyone

Many people sail through a fasting period, and others struggle. Some people can continue with their exercise program, and others have to rest. It is often best to schedule your fasting period for the weekend, so if you need to relax, you can. Also on the weekend, you can go and do fun things which are a good idea to keep your mind occupied, instead of thinking of food. As with most things in life, the more you practice, the easier it gets. The same applies to fasting. Fasting does get easier. Some feel full of energy during a fast and have no problems with fasting at all. Most people love the renewed energy, clear mind, sharper thoughts, clearer skin and other health benefits intermittent fasting has to offer.

Before you sail into intermittent fasting, let’s take a look at all the incredible benefits of intermittent fasting. If you know about the health benefits of fasting it might help you succeed with your first fast and it may even make the whole job of fasting easier.

Intermittent Fasting Benefits

One of the benefits of intermittent fasting is it will certainly lower the cost of your grocery bill. Most intermittent fasting programs suggest only drinking water and herbal, decaffeinated tea during your fast. While other intermittent fasting plans limit the amount of food you eat during a fast. Studies and many experts including Dr Michael Mosley say intermittent fasting helps us with a host of health conditions such as improvements in blood pressure, cholesterollevels, and insulin sensitivity (1). Intermittent fasting may also help improve the health of your heart, brain, waistline, immune system and health conditions including:

Alzheimer’s

Brain health including mental clarity and protection against Alzheimer’s have been shown to improve with intermittent fasting. These suggestions come from studies only done on rats, but these studies are looking good for us humans (2). Regardless of whether you have Alzheimer’s disease you often hear IF helps many people with a sharper thinking process and a clearer mind.

Diabetes

Intermittent fasting has been shown to lower insulin resistance, which may protect you from type 2 Diabetes (3). Diabetes is a complex health condition. Insulin is essential for the conversion of glucose into energy. When people with diabetes eat carbohydrates such as; slices of bread, cereals, fruit and starchy vegetables, legumes, milk, yoghurt and sweets, they can’t convert carbohydrates into energy. The glucose from carbohydrates stays in their blood resulting in high blood glucose levels.

Recent studies are showing success stories involving people with diabetes (4). After a few months of intermittent fasting, their diabetic condition had considerably improved (5). According to this study, the intermittent fasting made the pancreas start producing insulin again. The fasting days seemed to give the pancreas enough of a rest which allowed it to recharge many of its cells. When food was reintroduced, the new cells were capable of producing insulin again. Although this trial was done on mice, another trail on humans has been done which suggests fasting may also be helpful for diabetics (6). We require more studies before we can make any claims but intermittent fasting is looking a promising regime to follow for not only diabetics but also for cancer, anti-aging and cardiovascular disease.

Pre-diabetes, also known as glucose intolerance is a term for metabolic health conditions which result in higher than normal blood glucose levels, otherwise known as Hyperglycemia. Studies are suggesting that alternate day fasting for three weeks may improve your glucose tolerance. A study found that alternate day fasting improved glucose tolerance (7).

Cancer

Anything associated with benefiting cancer can be a tricky subject. So far, we only have studies on animals that have shown promising results suggesting intermittent fasting may help with cancer (8). However, extended fasts have additional benefits on cancerous cells and are very promising due to increases in autophagy.

Gut Conditions

Many experts believe that an unhealthy gut is the cause of all diseases. Healthy gut conditions directly influence the functioning of your immune system, digestion, hormonal balance and nutrient absorption.

An unhealthy gut may lead to many bowel disorders, inflammatory bowel disease, allergies, gas, bloating, constipation, diarrhoea, bad breath, flatulence, burping, poor skin health, imbalanced hormones, obesity, autoimmune diseases and diabetes. For optimal health, it is advised to improve and balance your gut microbiota, otherwise known as your gut flora. Food, lack of exercise and stress, has a direct influence on your gut flora.

Along with prebiotics and probiotics, fasting has also been shown to improve the integrity of your gut flora by cleansing cells of accumulated toxins, strengthening the gastrointestinal mucosal lining, reducing inflammation, enhancing metabolism and balancing your gut flora.

Heart Disease

Intermittent fasting may indirectly help heart disease. Findings are that intermittent fasting lowers your LDL cholesterol, blood triglyceride, inflammation levels and improve your blood sugar and insulin resistance which are all directly related to heart disease (9).

Inflammatory Conditions

Along with gut health, many experts suggest that your inflammatory levels may also be key drivers behind many health conditions and diseases we see in our society today. Studies show that intermittent fasting helps with reducing your inflammatory markers (10).

Obesity

According to the World Health Organization obesity is a global epidemic. Obesity can be a complicated condition to address. There are many contributing factors other than overeating which needs addressing. As mentioned before, fasting helps improve the integrity of your gut flora. A healthy gut flora, many believe directly helps with weight loss. Thousands of people globally have lost significant amounts of body weight with an intermittent fasting program combined with a regular exercise routine and healthy diet.

Stress

Scientific studies are showing that the process of intermittent fasting and the strain this puts your cells under may help your cells’ become more resistant to stress (12).

How Intermittent Fasting Can Help With Weight Loss

The verdict out there is, yes, intermittent fasting can be an effective method of weight loss (13). If intermittent fasting seems like some form of torture which sends you into a spin of fear, then I’m sure there will be a far more effective way for you to lose weight. Although losing weight is a hard job, your weight loss journey should be an enjoyable and realistic one.

On the other hand, if you thrive and strive towards your next day of fasting, then yes, this popular method of weight loss could be for you. How beautiful to be practicing intermittent fasting for weight loss, but also at the same time improving your health with the host of other health benefits intermittent fasting boasts.

As you’ll learn inside the 131 Method program, weight loss is not as simple as eating less food, cutting the calories and exercising more. If it was, we wouldn’t have an obesity epidemic on our hands at the moment. The disappointing thing is that with prolonged restriction of calories your body adapts to the calorie restriction and prevents further weight loss. You will most likely lose weight initially then after a while you will hit a weight loss plateau. Hitting a weight loss plateau is where intermittent fasting may suddenly become your new best friend. Evidence-based research does indicate that intermittent fasting may also help with your body composition and energy metabolism (14).

How Intermittent Fasting Improves Your Metabolism

Metabolism is when your body converts what you eat and drink into energy. Metabolism is linked to weight loss because theoretically, the faster your metabolism is working, the more calories your body will burn and the more weight you will lose. A slow metabolic rate may cause weight gain and many other symptoms. Sometimes this is the case. Unfortunately, weight gain is complicated, and often it is also due to hormones, diet, stress, poor sleep, environmental impact, work conditions and lack of physical activity.

Intermittent fasting indirectly boosts your metabolism by improving a host of conditions including lowering your levels of insulin which facilitates fat burning (15). Interestingly, your levels of human growth hormone (HGH) increase during a fast (16). HGH aids fat loss and muscle gain. Also, your nervous system sends norepinephrine to your fat cells making them break down your body fat into free fatty acids. These free fatty acids are used for energy (17). These studies lead us to believe that short-term fasting increases fat burning. Short-term fasting refers to fasting for a length of time less than two days. Fasting for any amount of time more than two days may suppress your metabolism.

How Intermittent Fasting Changes Your Belly Fat

Adipose tissue is the term given to your body fat. There are two different types of adipose tissue, white adipose tissue and brown adipose tissue. Brown adipose tissue, or brown fat, is sometimes called the ‘good’ fat as its main function is to burn calories to generate heat. White adipose cells or white fat is considered ‘bad’ fat. White fat is often the result of overeating. Excess calories are converted into an energy reserve in the form of white fat. White fat around the abdominal area, otherwise known as ‘belly fat’ is associated with various metabolic diseases including; obesity and diabetes. Studies show that ‘every other day’ type of fasting program may stimulate brown ‘good’ fat development within the white ‘bad’ adipose tissue (18).

Intermittent Fasting Diet Plans

There is always a new diet that seems to hit the headlines of the health and wellness world. There are various new and trending diets which are versions of intermittent fasting. These diets seem to base themselves on either alternate day fasting, whole day fasting or time restricted fasting.

Alternate Day Fasting

Alternate day fasting is just as the name implies. You alternate between days of no food, or limited amount of certain foods, with days of eating what you like.

Whole Day Fasting

Whole day fasting involves 1 or 2 days per week of fasting or eating only a limited amount of calories with days of eating what you like on the other days of the week. Probably the most popular intermittent fasting plan of this type of whole day fasting method is Dr Mosley 5:2 Fast Diet. Dr Michael Mosley suggests no food restrictions for five days of the week and a 500 calories for women and 600 calories for men diet on the other two days of the week.

Time Restricted Fasting

The other type of fasting is the time restricted fasting. Time restricted fasting involves following a meal plan every day with a scheduled timeframe for starvation. You eat your meals from 8 am – 3 pm and fast for the remaining hours. Also not too much of a daunting thought considering you will be sleeping for the majority of these fasting hours. Studies suggest that both alternate day fasting and full day fasting are effective at reducing body weight, body fat and reduce total cholesterol.

If weight loss is your goal, we have the evidence to suggest that alternate day fasting and whole day fasting will do just that (due to the downstream effects). Let’s take a look at some of the trending intermittent fasting diets out there at the moment.

5:2 Fast Diet

The 5:2 Fast Diet has helped thousands of people with weight loss and a host of health conditions including lowering inflammation. Dr Michael Mosley created the diet which suggests you eat what you like for five days and on the other two days you restrict your calorie intake to 500 calories for women and 600 calories for men. Luckily, if the whole fasting process daunts you, you can separate your two fasting days.

16:8 Diet

This diet is also known as Leangains. Nutritional consultant and personal trainer Martin Berkhan created the name though this style of eating in a shortened window has been around for years. He suggests fasting for 16 hours overnight and into the morning and then you can eat for 8 hours during the afternoon and evening. There is a calorie restriction involved during your eating window, depending on how severe your weight loss goals are. During the fasting window, you can eat some food and drink, but only with a small number of calories such as a coffee with a splash of milk. This diet plan is popular if you are not a fan of eating breakfast. Effectively, you are eating between the hours of 12 pm – 8 pm.

Warrior Diet

Ori Hofmekler created this type of intermittent fasting diet plan. This diet is more of a radical, but simple lifestyle overhaul. Ori Hofmekler has based this diet on our primal habits of earlier cultures. He draws on historical and scientific studies suggesting that healthy and lean bodies are achieved by living how our ancestors did. Eating sparingly during the day and filling up at night. You fast for 20 hours every day and then enjoy one large meal every night. During this fasting period, you can eat raw fruit and vegetables, fresh juice and small amounts of protein. There are also restrictions on what you can eat for your evening meal.

Eat Stop Eat

Brad Pilon devised this fasting diet which is similar to the 5:2 diet. This diet suggests doing one or two 24 hours fasts every week. For weight loss, this plan advises you to continue with working out.

Fat Loss Forever

This intermittent fasting diet plan allows you to have one cheat day each week. This cheat day is to be followed by a 36 hour fast. For the remainder of the week, you follow different fasting protocols. The fasting and eating schedule vary each day.

131 Method

The 131 Method teaches you how to use various methods of fasting that fit the individual’s needs best. The goal is to address underlying hormonal imbalances, inflammation, insulin resistance, etc that can be supported by various types of fasting. Click here to learn more.

Concerns With Intermittent Fasting

Fasting for longer than 24 hours, particularly for 3 or more days should be done under the supervision of your healthcare professional or after education on proper prepping and refueling. Fasting is not recommended for children, if you are underweight or if you are on any certain medication.

While you are sleeping, your body is naturally fasting. Fasting during your sleep allows your body to rebuild and detoxify. However, fasting can be stressful for your body if you continue to fast during the day as you are conscious of being hungry, possibly feel starved and sometimes feel exhausted because you have not eaten for hours. This lack of food triggers your sympathetic ‘fight or flight’ nervous system to kick into gear. This is temporary stressor and in the longer term, can be a healthy stressor when used correctly.

Stress

Working out during your fast is sometimes encouraged but it’s very individualized. Generally, this is not recommended during your first few fasts but once you’re experienced, it’s easier to exercise while fasting. Exercising during fasting often causes cortisol levels to increase to a staggering 105% by the end of the workout. This study was conducted in comparison to a group who had eaten a protein and carbohydrates before their workout. This group showed no increase in cortisol levels. However, another study suggests that alternate day fasting may improve your stress resistance (19).

Fertility

Intermittent fasting has been shown to impact fertility both positively and negatively. In the case of amenorrhea which is a health condition when you have a loss of menstrual cycle fasting may not be ideal. Additionally, if you are under your recommended body weight due to lack of nutrients and food, fasting is not for you. However, fasting can reduce inflammation and have hormonal impacts due to the ketones produced which can positively impact hormones and fertility. It’s best to know what potential underlying factors are leading to infertility and make decisions from there.

Athletes

If you are an athlete, you need to be on your peak performance while you are competing and for most of your training sessions. You may be able to squeeze in a fast between your training sessions but be careful of fasting close to your competition (unless you have practiced these before and can easily slip into ketosis). Fasting may leave you feeling mentally and physically flat the first day or two, which is not your ideal training condition. Intermittent fasting has been touted to reduce your inflammatory levels. Therefore, intermittent fasting is excellent when practiced during your training and competition resting period. As an athlete lowering your inflammatory levels is one of your many areas of focus. Sports Dietitians Australia suggests that intermittent fasting has the potential to positively impact on your recovery (20). The Sports Dietitians Australia also indicate that intermittent fasting may help with weight loss, fat burning, reduced inflammation, increased growth hormone secretion and a host of metabolic and performance benefits.

How To Start Intermittent Fasting

We suggest starting slowly and gradually increasing your intermittent fasting hours. Learn exact details inside the 131 Method. Begin by eating your evening meal at 7 pm and don’t eat anything until 7 am the next morning, giving you a good 12 hours of fasting. Continue to do this 12 hour fast once a week for a couple of weeks before stretching out your fast to 16 hours.

For a 16 hour fast, eat your evening meal at 7 pm and don’t eat your breakfast until 11 am the next morning. Continue doing your 16 hours fast for one day every week for the next couple of weeks.

During these 12 to 16 hours of fasting, you are not eating anything. You need to be drinking as much water, herbal teas and other healthy decaffeinated liquids as possible. Once you feel you can master 16 hours of fasting you may like to try some of the other intermittent fasting programs.

Add some deliciously nutritious flavors to your filtered water. You might like to try adding some fresh slices of lemon, or a few slices of oranges, or a few blueberries or some sprigs of mint. The juice of a freshly squeezed lemon in water may help boost your metabolism, give you some strong antioxidants and may also help protect your cells from damage. Lemons also contain a really important potassium which may help support the health of your heart. Many weight loss programs suggest drinking a glass of lemon juice in warm water first thing in the morning. This will assist with overall weight loss, is fantastic for your digestion and also excellent for cleansing your body.

Create A Positive Mindset

Schedule your fast for the weekend when you can rest if you need to. Don’t overcommit yourself before, during or after your fasting days. Create space for yourself, free your mind and take time out to cleanse and nourish your mind, body and soul (21). Create an enjoyable ritual for your fast days, so fasting becomes something you enjoy. Practice a restorative yoga sequence or maybe meditate for a few hours. Buy yourself some beautiful flowers, take some long hot baths, spring clean your wardrobe and do anything else that will uplift you. Drink plenty of water with a delicious slice of lemon in it. Spoil yourself in other ways other than food. You might be amazed at how much you enjoy the simple things in life.

Who Should Be Careful Of Intermittent Fasting

Intermittent fasting reviews vary enormously. As we have established, fasting is not for everyone, but from all the health benefits we have discussed, we encourage you to give intermittent fasting a try. If you are pregnant, breastfeeding, a child, an adolescent, on medication, have a medical health condition, diabetes, hypothyroidism, underweight, malnourished or have an eating disorder consult your healthcare professional before you start any intermittent fasting program.
