Is Fasting Actually Effective For Weight Loss Here’s What The Latest Research Says
Some research has hinted that eating within certain windows, aka intermittent fasting or IF, might align better with our circadian rhythms and may improve blood sugar and cholesterol and boost longevity. For this reason, IF has been having a moment over the last decade.
Celebrities from Jennifer Aniston to Jimmy Kimmel have given it a shot, and dozens of diet books have been released explaining how to follow one of the plans, be it the 5:2 method, 16/8, eat-stop-eat or the warrior method.

Not to mention, for most of us it’s just downright difficult to stick with for the long haul. What about those birthday dinners that involve reservations at 8 p.m. after we have a business lunch at noon?
A new study, published April 21 in the New England Journal of Medicine, clarified that last detail. Scientists at Southern Medical University in China found that over the course of a full year, people who only ate from 8 a.m. to 4 p.m. didn’t lose significantly more weight than those who ate at any time throughout the day. Let’s break down this new research.

There Is Interest In Whether Autophagy Can Increase The Lifespan Of Whole Organisms Though So Far This Has Only Been Replicated In Animals
There is interest in whether autophagy can increase the lifespan of whole organisms, too though so far this has only been replicated in animals, like 1mm-long nematode worms and mice, and not humans . Until there are longitudinal studies of human intermittent fasters, it is too soon to say that it will extend our lifespans.
But, other animal studies have linked autophagy to improvements in immune system memory. The fact that autophagy is essential to maintain cell health has also generated interest in its role in cancer suppression. There might be more reasons than increasing lifespan to take interest in autophagy.

With these FAQs and scientific research results, you now have an in-depth understanding on the weight loss benefit of intermittent fasting. Let us share our final thought:
Is Intermittent Fasting Right For You
Intermittent fasting is safe for many people, but it’s not for everyone. Skipping meals is not recommended for people under 18, those with a history of disordered eating, or those who are pregnant or breastfeeding. Athletes may find it difficult to fuel and refuel appropriately for an active lifestyle. If you have diabetes or other medical issues, talk with your health care team before starting intermittent fasting.
Also, note that the key to weight loss with intermittent fasting is not to overeat during your eating windows. Eating fewer calories than you expend remains the basis for losing weight.
Shortening the eating window may make it difficult to get the vitamins and minerals you need. While on this diet, it is important to eat meals made from quality, healthy ingredients, such as fruits, vegetables, whole grains, low-fat dairy and lean protein.
Intermittent fasting can be dangerous if taken too far. A technique called dry fasting restricts food and fluid intake, resulting in severe dehydration and posing serious health concerns. Malnutrition can occur if the caloric restriction is too severe, such as averaging fewer than 1,200 calories a day long term.

How Does Intermittent Fasting Affect My Body
When you fast, you consume fewer calories than normalor no calories at allwhich reduces your overall calorie intake. Reducing your calorie intake can help you lose weight, but it also causes several changes to the way your body stores and burns fat.
Insulin, a hormone produced by the pancreas, converts glucose in your blood into energy that your cells use as fuel. Insulin also drives fat storage. Your bodys insulin levels increase when you eat and decrease when you fast. Lower insulin levels resulting from fasting can prevent additional fat storage and help your body mobilize stored fat.

Does Fasting Work Fasting And Your Hormones
Fasting is so effective for weight loss because it helps normalize your fat storing hormones, it helps liberate fat stores in your body, it reduces inflammation, helps normalize your appetite and it reverses hormone resistance syndromes.
Let’s break apart each one of these into more detail.
#1. Fasting helps normalize fat storing hormones.
Restricting the food you eat for 4 to 8 hour periods has been shown to help reduce body weight, improve fasting blood sugar and level out blood sugar throughout the day.
Much of this is accomplished through the effects of insulin.
Insulin is a fat storing hormone which is secreted in large amounts after you eat meals high in carbohydrates.
Bread, pasta, cereal, etc. all of these foods trigger the release of insulin because your body wants to take those foods and store the calories for later use.
This is great if you have a temporary abundance, but if you have a consistent abundance it leads to insulin resistance and chronic fat storage.
#2. Fasting helps liberate fat stores in your body.
In order to get in and break down your fat, you must first activate an enzyme known as hormone-sensitive lipase.
If you don’t activate this enzyme then your body will hold onto your fat cells with a lock and key.
Hormone-sensitive lipase, as the name suggests, is sensitive to hormones!
In this case, it is sensitive to insulin levels.
In the presence of high insulin, your body will lock up your fat cells and you won’t be able to get in.
