Fasting retrains your body to become fat adapted. This means you burn stored body fat for energy, rather than being dependent on sugars from food. This is empowering because you become completely self-sufficient. Not only will you lose weight, you will be FULL of energy all day long, no longer reaching for caffeine or nicotine or sugar to get you through the day.

Recent studies have shown that intermittent fasting has some amazing benefits:

It resets the body to burn fat for energy rather than sugar, which has been shown to dramatically decrease the risk of chronic disease.
Increases insulin sensitivity, which can help combat type 2 diabetes and metabolic disease
Your hunger hormones stabilise, which means you feel LESS hungry! Giving you control back over your body and impulses.
You switch on your bodies innate cleansing and healing properties known as a process called Autophagy, this has been shown to boost the immune system.


Here’s The Technical Bit
When you extend periods of non-eating some amazing things happen:

Growth Hormone (GH) increases which not only preserves muscle mass but can actually help cause growth in muscle, bone density, and cartilage. An increase in GH effects adipose tissue (Fat) by breaking stored body fat into fatty acids which can be used for energy throughout the body; in fact, they are worth more than carbohydrates (this explains the stable energy levels).
Norepinephrine increases which has been shown to have an effect on the mind as well as the body. High Norepinephrine levels have been shown to increase mental alertness, and boost the metabolism of fat. Conversely, scientists now think that low levels can cause depression.
Insulin Sensitivity increases. Short term this can benefit you by directing carbs to your muscles for muscle gains, rather than being converted to fat. Conversely being insulin insensitive long term can lead to Type 2 diabetes, Alzheimer’s and heart disease.
Ghrelin (“the hunger hormone”) levels are normalised.
Cortisol levels are at their highest in the mornings, eating with raised cortisol levels have been shown to increase post-meal hunger and increase insulin resistance (This is why people find it much easier to control cravings when using IF.)
As well as these processes going on in the body fasting has been shown to:

Increases gene and cell repair
Increase longevity
Reset the body to burn fat for energy (ketosis) rather than sugar, which has been shown to dramatically decrease the risk of chronic disease.
Lowering triglyceride levels and improving other biomarkers of disease
Reduce oxidative stress
Being insulin sensitive boosts mitochondrial energy efficiency (all cells are more efficient at using energy)
Reduces cancer risk. There is also evidence to suggest fasting can decrease the effects of chemotherapy.v
Improves cardiovascular health
Reduces Alzheimer’s risk

Fat Burning Machine
Our bodies are naturally fat burning machines, but because of clever marketing and an abundance of ‘food like products’, we have become dependent on sugar to supply us with energy. Every time we have that mid-morning snack we create a blood sugar spike, which causes the hormone insulin to be released. Excess insulin not only causes us to put on fat, but it actually stops us from burning the fat we already have. Long term this can lead to type 2 diabetes, obesity, Alzheimer’s and heart disease.

Eating ‘little and often’ or ‘grazing’ has become the social norm with the myth that it keeps the metabolism ring. Unfortunately, we are encouraged to snack in between meals by companies who create ‘food like products’ which are cheap, nutrient sparse, and highly processed. To achieve your fat loss goals, avoid these products.

You may feel that there is a lot of food on this meal plan, but what you are trying to achieve is to turn your body into a fat burning machine. This is called ketosis. It is important to fuel your body with nutrient-dense foods, especially when exercising.

Eating enough at meal times is crucial so you aren’t tempted to snack on poor quality food in-between meals. Digestion takes up a lot of energy and contributes to energy slumps throughout the day. Fasting will help stabilise blood sugar levels and force your body to draw on its own fat reserves for energy, rather than being dependent on a constant stream of food.

It will take time for your body to get used to this way of eating, and it may be difficult for some of you. But once your body goes into ketosis you will quickly reap the benefits of stable energy levels, feeling “real hunger” (every 12-24 hours), dropping body fat, and not being a slave to hunger.

Most importantly skipping breakfast or dinner does NOT slow down your metabolism, in fact, short-term fasting actually increases your metabolic rate by 3.6-14%, helping you burn even more calories.

Actually skipping breakfast is only bad for a normal nutrition diet, but if you are on a detox diet for example you dont skip meals but you replace them with high-fiber juices - juice cleanse. It is a very effective way of fasting, where you clean your body with natural detox juices

It helps boost your metabolism, in the effect you burn more calories or just maintain your existing weight. Another bonus is you are always full of energy.
