If you are still hungry, that is a sign that you should absolutely take a break from the fast. Making the choice to break a fast without feeling guilt is very important at the onset of this process. Your body is still adjusting, so be gentle with yourself.
In contrast, those who are starving can develop brain dysfunction, heart failure and convulsions and ultimately die of starvation if the condition persists. The longer an individual fasts, the more likely he is to expose himself to some type of starvation.
Intermittent fasting does not mean starving yourself, which can cause the body to hold onto stored fat instead of burning it off as fuel.
There's a strong biological push to overeat following fasting periods because your appetite hormones and hunger center in your brain go into overdrive when you are deprived of food.
How Long Does It Take For Intermittent Fasting To Work? After beginning your intermittent fasting routine, you could see changes in your body in as little as ten days. More significant weight loss is seen after two to ten weeks.
Myth or Fact: If you cut down on your food intake, you'll eventually shrink your stomach so you won't be as hungry. Answer: Myth. Once you are an adult, your stomach pretty much remains the same size -- unless you have surgery to intentionally make it smaller.
Strictly speaking, any amount of calories will break a fast. If a person follows a strict fasting schedule, they should avoid any food or drinks containing calories. Those following a modified fasting diet can often eat up to 25% of their daily calorie needs while fasting.
If you don't eat for 10–16 hours, your body will go to its fat stores for energy, and fatty acids called ketones will be released into the bloodstream. This has been shown to protect memory and learning functionality, says Mattson, as well as slow disease processes in the brain.
Metabolic switching through intermittent fasting results in improved metabolism, increased health span, and increased longevity through multiple processes [16,30].
Final thoughts on stopping intermittent fasting
Extreme hunger, excessive weight loss, dehydration, low blood pressure, and weakness can be adverse health effects of fasting. If fasting is impacting your emotions, decreasing your energy levels, or causing extreme hunger, it may be time to stop.
Intermittent fasting is commonly associated with weight loss. However, Newgent explains that many people actually gain weight due to overeating during non-fasting times. She also points out that “any long period of fasting can ultimately slow down your metabolism.”
This is how much weight you can lose with intermittent fasting. In doing the fast correctly and ensuring that it is aligning with your mind, body and soul–you can expect a good weight loss of anywhere between 2 to 6 kgs a month with excellent inch loss and increase in energy levels and brain function.
Over the long term, it's smart to aim for losing 1 to 2 pounds (0.5 to 1 kilogram) a week.
That suggests that fasting could have benefits for weight loss if it helps people reduce their calorie intake without tracking or restricting certain foods. The results of this study, however, suggest that fasting by itself, without calorie reductions, does not have any particular benefits for weight loss.
Remember, fat-free mass includes any mass on the body that does not have fat, such as the bones, organs, and lean muscle. Because starvation leads to not only a loss of fat, but a loss of lean muscle, organ tissue, and skeletal mass, the body begins to work to regain the lost mass.
