Why do people juice?
Juice fasting is also referred to as juice cleansing. Many people who undergo a juice fast aren’t just trying to lose weight, they’re also looking to beef up the nutrients in their bodies.

Juicing is a process that extracts the juices from whole fruits and vegetables. What’s missing from juice is the fiber that’s found in the pulp. While fiber is a healthy part of your diet, some people have digestive issues when they consume too much. Read more about the risks of consuming too much fiber.

Pure juice contains most of the vitamins, minerals, and phytonutrients in fruits and vegetables. People who juice say it gives their digestive systems a break while allowing them to better absorb a great deal of nutrients. Others swear by juicing as a way to:

boost the immune system
remove toxins from the body
lose weight
Some people even claim that juicing helps reduce the risk of cancer, though there’s no evidence to support this claim.

Safety:
Before you go on a strict juice fast, understand that most doctors don’t recommend drinking only juice. There are several reasons why.

Drinking only juice may be rich in vitamins and minerals, but it lacks protein. Your body uses protein to build and maintain muscle. When you’re drinking only juices, you may lose weight, but some of that weight may come from healthy muscle.

Juices may contain more sugars than you think, which can possibly lead to weight gain. Not only that, but since juice lacks protein and fat, it may lead to severe blood sugar swings as well.

Juices loaded with green leafy vegetables like kale, spinach, or collards may also lead to health issues. These veggies contain what’s called goitrogen. Goitrogen is a substance that can affect your body’s absorption of iodine. If you get too much goitrogen, it may result in slowed thyroid function.

The following research is from DukanDiet.com

One of the strongest points in favor of this diet is the fact that you never have to weigh or measure your food and you can eat as much as you like. There is no counting of carbs, calories or any other nutritional values in any phase of The Dukan Diet. In The Dukan Diet, you eat from the list of 100 foods, while including other foods in the Consolidation phase. Portion sizes are based on how hungry you feel. If you are still hungry you can eat some more! Anyone who reads the official book will immediately see that the Dukan Diet encourages you to eat as much as you want! No starvation here. Furthermore, the Dukan diet has 4 phases which are: attack phase, cruise phase, consolidation phase, and stabilization phase.

By explaining the first stage which is attack phase it is also known as the Pure Protein (PP) phase. The sudden change in your eating habits triggers a fast and encouraging weight loss, which works to motivate you for the rest of your diet. The second stage; the cruise phase reintroduces vegetables with Proteins and Vegetables (PV) days and establishes the 100 unlimited allowed foods as a base. The goal of the Dukan Diet Cruise phase is steady weight loss until you reach your True Weight. The third stage; consolidation phase is about how to preserve and maintain your True Weight reached at the end of the Cruise phase. The last stage, which is the stabilization phase it maintains permanent Stabilization after your weight loss.

In addition, the Dukan Diet gives you many options, including a list of 100 approved foods. Examples are eggs, chicken, fat-free daily products, vegetarian’s proteins, shellfish, lean meat, and poultry. You don’t have to think about the food you’re eating and whether or not it will cause you to gain weight – you can be confident the approved foods will not cause you to put on any pounds. It’s auto-pilot for weight loss.

However, there is a tendency to consider anything new a fad. Yes, the Dukan diet is new to the USA and Canada, but this weight loss program has a long history. The official book is translated into 10 different languages and has been the diet of the French for the last 20 years.

The science behind the Dukan diet is nothing new and is based on proven nutrition principles and it affects one's health in different ways.

The Dukan diet encourages you to eat whole unprocessed natural foods free of chemicals and preservatives. Dr. Pierre Dukan emphasis’s the importance of preparing your own food from scratch and savoring each meal. The diet urges you to drink plenty of water, to eat healthier, more balanced meals and to avoid high sodium processed foods as well as fatty, sugary snacks and desserts.

The Dukan Diet focuses on lean protein including non-fat dairy – which is great for your heart. Fresh vegetables, fruits, and whole-grain products plus your daily serving of oat bran are the foundation of the Stabilization phase that you will follow for the rest of your life. Many people eat too many carbohydrates, particularly bread, potatoes, rice, and pasta. The Dukan diet teaches us that it’s possible to cut down on these carbohydrates dramatically without sacrificing taste, flavor, and enjoyment.

Moreover, the Dukan diet affects one’s health by preventing them from type two diabetes, heart and stroke. This is proved by that the Dukan Diet is low in carbs, The Dukan Diet is low in fat, The Dukan Diet is low in salt, The Dukan Diet prescribes exercise, and The Dukan Diet is a long term solution,

Finally, the Dukan Diet is not just about nutrition, it also incorporates regular exercise as an essential part of the program. It should be no surprise that many people who follow the Dukan Diet report better overall health conditions beyond weight loss, including decreased cholesterol levels, lower A1C readings, and lower blood pressure.

What is Keto Diet?
The Keto Diet or known as ketogenic diet is a very low-carb, high- fat diet that offers many health benefits and it shares many similarities with the Atkins and low-carb diets.

This type of diet can help you lose weight and improve your health and it may even have benefits against diabetes, cancer, epilepsy and Alzheimer’s disease.

Although the ketogenic diet is safe for healthy people but there may be some initial side effects and it often referred to as the “keto flu” and is usually over within a few days.
Keto Flu includes poor energy and mental function, increased hunger, sleep issues, nausea, digestive discomfort and decreased exercise performance.

A ketogenic diet can also change the water and mineral balance of your body, so adding extra salt to your meals or taking mineral supplements can help.

What is carb cutting or a low carb diet?
Carb cutting is a form of diet in which a person lowers or cuts the consumption of carbohydrates and is also considered as a fad diet. People mostly follow this diet style when they are trying to lose weight. It can also deprive the body of needed nutrients if taken to extreme measures.


What are carbohydrates?
Carbohydrates are macronutrients found in foods like sugar, fibre found in food, vegetables, grains and milk. They are considered as power bodies which provides energy to us. The main goal of carb limitation is to burn off the body’s fat stores.

• Benefits of low carb diet.
Low carb diet, according to livescience.com and Fitzgibbon is used to treat or prevent some chronic diseases such as diabetes, high cholesterol which is harmful for our heart, hyperinsulinemia and obesity. It is also proven that low carb diet helps people lose weight faster. According to website livescience.com and writer Alina Bradford, a study published in the New England Journal of Medicine found that subjects who ate a low-carbohydrate diet lost more weight than subjects on a conventional diet for the first six months.

• How it maybe affects one’s health in a negatively.
This diet may work for several people, but it has some weak points. The main weak point is that that it often cuts out healthy carbs as well as unhealthy carbs and replaces them with high fat meats, cheese, fish and poultry. Consuming an unlimited amount of fat and meat and restricting carbs is a dangerous practice that many health professionals criticize the Atkins Diet for advocating. Some people may also take carb cutting diet to extreme measures and forgets that carbs are the also used to generate power in our body. Human body needs fibres obtained from carbs to digest properly, colon health and insulin regulation.

paleo diet is a dietary plan based on foods similar to what might have been eaten during the Paleolithic era, which dates from approximately 2.5 million to 10,000 years ago.

A paleo diet typically includes lean meats, fish, fruits, vegetables, nuts and seeds — foods that in the past could be obtained by hunting and gathering. A paleo diet limits foods that became common when farming emerged about 10,000 years ago. These foods include dairy products, legumes and grains.

Other names for a paleo diet include Paleolithic diet, Stone Age diet, hunter-gatherer diet and caveman diet.

Purpose
The aim of a paleo diet is to return to a way of eating that's more like what early humans ate. The diet's reasoning is that the human body is genetically mismatched to the modern diet that emerged with farming practices — an idea known as the discordance hypothesis.

Farming changed what people ate and established dairy, grains and legumes as additional staples in the human diet. This relatively late and rapid change in diet, according to the hypothesis, outpaced the body's ability to adapt. This mismatch is believed to be a contributing factor to the prevalence of obesity, diabetes and heart disease today.

Why you might follow a paleo diet
You might choose to follow a paleo diet because you:

Want to lose weight or maintain a healthy weight
Want help planning meals
Details of a paleo diet
Recommendations vary among commercial paleo diets, and some diet plans have stricter guidelines than others. In general, paleo diets follow these guidelines.

What to eat
Fruits
Vegetables
Nuts and seeds
Lean meats, especially grass-fed animals or wild game
Fish, especially those rich in omega-3 fatty acids, such as salmon, mackerel and albacore tuna
Oils from fruits and nuts, such as olive oil or walnut oil
What to avoid
Grains, such as wheat, oats and barley
Legumes, such as beans, lentils, peanuts and peas
Dairy products
Refined sugar
Salt
Potatoes
Highly processed foods in general
A typical day's menu
Here's a look at what you might eat during a typical day following a paleo diet:

Breakfast. Broiled salmon and cantaloupe.
Lunch. Broiled lean pork loin and salad (romaine, carrot, cucumber, tomatoes, walnuts and lemon juice dressing).
Dinner. Lean beef sirloin tip roast, steamed broccoli, salad (mixed greens, tomatoes, avocado, onions, almonds and lemon juice dressing), and strawberries for dessert.
Snacks. An orange, carrot sticks or celery sticks.
The diet also emphasizes drinking water and being physically active every day.

Results
A number of randomized clinical trials have compared the paleo diet to other eating plans, such as the Mediterranean Diet or the Diabetes Diet. Overall, these trials suggest that a paleo diet may provide some benefits when compared with diets of fruits, vegetables, lean meats, whole grains, legumes and low-fat dairy products. These benefits may include:

More weight loss
Improved glucose tolerance
Better blood pressure control
Lower triglycerides
Better appetite management
However, longer trials with large groups of people randomly assigned to different diets are needed to understand the long-term, overall health benefits and possible risks of a paleo diet.

Questions about paleo diets
Concerns or questions about the paleo diet include both food selection and the underlying hypothesis.

Dietary concerns
A paleo diet is rich in vegetables, fruits and nuts — all elements of a healthy diet.

The primary difference between the paleo diet and other healthy diets is the absence of whole grains and legumes, which are considered good sources of fiber, vitamins and other nutrients. Also absent from the diet are dairy products, which are good sources of protein and calcium.

These foods not only are considered healthy but also are generally more affordable and accessible than such foods as wild game, grass-fed animals and nuts. For some people, a paleo diet may be too expensive.

Questions about the paleo diet hypothesis
Researchers have argued that the underlying hypothesis of the paleo diet may oversimplify the story of how humans adapted to changes in diet. Arguments for a more-complex understanding of the evolution of human nutritional needs include the following:

Variations in diet based on geography, climate and food availability — not only the transition to farming — also would have shaped the evolution of nutritional needs.
Archaeological research has demonstrated that early human diets may have included wild grains as much as 30,000 years ago — well before the introduction of farming.
Genetic research has shown that notable evolutionary changes continued after the Paleolithic era, including diet-related changes, such as an increase in the number of genes related to the breakdown of dietary starches.
The bottom line
A paleo diet may help you lose weight or maintain your weight. It may also have other beneficial health effects. However, there are no long-term clinical studies about the benefits and potential risks of the diet.

You might be able to achieve the same health benefits by getting enough exercise and eating a balanced, healthy diet with a lot of fruits and vegetables.
