Studies have shown that extended fasting, such as water fasting for a week or more, can result in positive effects like weight loss, body fat loss, reduced levels of perceived stress, increased ketogenesis, and decreased blood sugar levels.
What Are The Benefits of A 7-Day Fast? The benefits of a 7-day water fast include weight loss, cell regeneration (autophagy), regulation of insulin levels, and liver rejuvenation, all resulting from low caloric intake and absence of sugars.
Some studies showed a weight loss of around 4–6kg within the first week alone. This is not all fat, however, as the weight loss also contains water and muscle glycogen. Still, it's a great way to kick-start your diet.
Water fasting will likely result in lean muscle wasting, or muscle mass loss that occurs when you don't take in protein, she says. To compensate, your body starts to break down muscles. You might develop other nutrient deficiencies as well.

Without water, a person can die after 3 days, and usually no one can survive for more than 5-6 days. Dr. Claude Piantadosi of North Carolina's Duke University says 100 hours is around the limit.
Therefore, even if don't feed your tummy it won't just shrink down. In fact, the repercussions of hunger might result in drastic weight gain. Your metabolism will eventually become slower which in turn will make future weight loss difficult.
This makes sense, since protein is functional tissue and there is no point to burning useful tissue while fasting when there is plenty of fat around. So, no, you do not 'burn' muscle during fasting.
The body needs the nutrients in food to survive. Without them, it will start to break down its own tissue to use as food. Starvation affects all of the body's systems and processes. It is difficult to determine how long someone can go without food, but experts believe that it is between 1 and 2 months.
Longer periods without food, such as 24-, 36-, 48- and 72-hour fasting periods, are not necessarily better for you, and may be dangerous. Going too long without eating might actually encourage your body to start storing more fat in response to starvation.
Can I Exercise While Fasting? Yes, it is OK to work out while fasting because the key to weight loss and muscle gain is not just calories and exercise, but hormone optimization.
Many medical experts agree that a one-day fast can feel great. But extending beyond three days can begin to cause harm, especially if you have other medical conditions, such as diabetes or heart disease. “A fast longer than a day or two can deplete vitamins, minerals and electrolytes,” Dr. Hopkins says.
A 48-hour fast can serve as a reset for the body, allowing it to take a break from digestion to focus on other tasks. This break may allow it to focus energy elsewhere, such as on repairing the body.
Eating processed foods or foods high in simple carbohydrates, particularly if you consume too much too quickly after prolonged fasting, can lead to refeeding syndrome, which is when fluid imbalances occur following a period of fasting.
A water fast is when a person does not eat and drinks nothing other than water. There is no set time that water fasting should last for, but medical advice generally suggests anywhere from 24 hours to 3 days as the maximum time to go without food.
The truth about lemon water and intermittent fasting
Long story short - the answer to the question “Does lemon water break a fast?” is no, lemon water does not break a fast. Lemon water contains almost no calories and zero sugars, it doesn't raise insulin levels, which means it will not break your fast (1).
Stay hydrated.
In addition to being essential for health, drinking plenty of water during a fast can also fill up your stomach and help you to feel full. Proper hydration will make your fast a whole lot easier, and help ease your transition back to food.
Your Slow Metabolism:
When you have a slow metabolism, your body doesn't convert food into energy in sufficient quantities. So most of the food you eat is stored in the form of fats. This is the main reason why some people get fat even though they don't eat much.
You can survive for 3 Minutes without air (oxygen) or in icy water. You can survive for 3 Hours without shelter in a harsh environment (unless in icy water) You can survive for 3 Days without water (if sheltered from a harsh environment) You can survive for 3 Weeks without food (if you have water and shelter)
As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this.
If a survivor where to find themselves in a situation where water was scarce they would obviously become dehydrated and the rate of urination would drop, for arguments sake to 500ml<. This leaves a rough figure of 1 Litre or 32 ounces to keep the average human alive whilst resting in a temperate environment.
