What Is A Crash Diet?

Crash diet Canadian Academy of Sports Nutrition 1Some people like to have a "beach body". Some people want chiselled abs. And some want their love handles to be melted away. Interestingly, most of them expect a quick fix towards their goals.

A genuine fat loss requires intellectually customized diets and carefully designed exercise plans. The growing rate of obesity around the world has made it a global challenge. This imposes a huge cost on health care systems through the consequences it gives birth to.

Weight loss seekers should keep in mind that there is no silver bullet to their problems. A sustainable weight loss requires setting realistic goals, scientific dietary changes, behavioral modifications and biochemical manipulations of the body.

The fact that the human body is very intricate and beautiful in its complex delicacy makes weight loss difficult and challenging to many. An increase in the number of so-called "fitness gurus"―who lack the basic knowledge of physiology and biochemistry―the bombardment of junk science through social media, nutritional quackery, and the profiteering of supplement industries are the major factors driving the promotions of unhealthy weight loss―also known as a crash diet.

The criteria of a crash diet:Crash diet Canadian Academy of Sports Nutrition 4

Crash diet is also called "fad diet" or "diet cult". There is no consensus about the definition of a crash diet. In general, people think of a crash diet as losing large amounts of weight in a short period of time. The general public believes that a fad diet promises quick weight loss through what is usually an unhealthy and unbalanced diet. However, that is not the case.

As per definition of the CAASN (Canadian Academy of Sports Nutrition), a crash diet has the following three criteria:

a) The person attempts to lose weight in a short period of time.

b) The total daily calorie count is less than 50% of that of BMR.

c) There is a decrease in muscle mass.

The speed by which you attempt to lose weight is an essential criterion for a crash diet. Generally if you are trying to lose more than 5 Ibs in a week, you meet the first criterion. You should bear in mind that "crash diet" and "quick weight loss" are two different concepts. Quick weight loss (also called rapid weight loss or sharp weight loss) is when you lose more than 3 Ibs in a week. In fact, every crash diet leads to a quick weight loss, but not every quick weight loss comes from a crash diet.

The second criterion to label a diet as a crash diet is the total amount of calories consumed. Overall, the total calories in a crash diet could be as low as 500 calories in a day. The Canadian Academy of Sports Nutrition defines a crash diet as when the total daily calories are less than 50% of that of BMR (basal metabolic rate). For example, if your BMR is 1268 calories and your total daily calories drops to below 634 calories, you meet the second criterion.

A decrease in muscle mass must also exist to define a crash diet. If your diet is very low in calories but your daily protein intake is high enough to save your muscle mass, you do not meet the third criterion. For instance, if you are a 45-year-old female with a body weight of 70 kg, then your BMR would be 1190 calories. If you go on a diet with 520 calories in a day, but your daily protein intake is 90 grams per day, you do not meet the third criterion because your protein intake is high enough to sustain your muscle mass.

What are some examples of crash diets?

Examples of crash diets include, but are not limited to: Crash diet Canadian Academy of Sports Nutrition 2

IgG4-Related Disease (IgG4-RD): Canadian Academy of Sports Nutrition IgG4 Related Disease 1Immunoglobulin G4 (IgG4)-related disease is a chronic inflammatory condition recognized as a systemic disease recently. It is characterized by dense infiltrates of lymphocytes and IgG4-secreting plasma cells in different tissues in the body. IgG4-RD is associated with an increased level of IgG4 in the blood in about 60-70% of cases especially during the acute phase.

The exact mechanism by which the IgG4-RD occurs is poorly understood. However, it has been postulated to be an autoimmune in nature. This condition could affect any organs in the body. The many faces of IgG4-RD requires that all health care professionals to get to know this newly proposed clinical-pathologic entity.

IgG4-RD has a relapsing-remitting nature associated with a tendency to form a destructive mass in the affected organs. In fact, the initial inflammatory infiltrates will be replaced by fibrotic lesions followed by forming pseudo-tumors in the affected organs, often leading to biopsy or excision for fear of true malignancy.

Several different diseases that have been known in medicine for many years are Canadian Academy of Sports Nutrition IgG4 Related Disease 2now considered to be the manifestations of IgG4-RD. This disease could affect one or multiple sites in the body such as salivary glands, thyroid, kidneys, pancreas, lungs, bile ducts, eyes, sinuses, mediastinum, skin, nerves, lacrimal and pituitary glands, prostate and cardiovascular system. Interestingly, IgG4-RD does not have much musculoskeletal involvements and manifestations.

There are no specific criteria to diagnose IgG4-RD clinically, and its definitive diagnosis requires histopathologic analysis. However, an increase in inflammatory markers in the blood and an elevation of IgG4 should make a health practitioner be suspicious of this culprit!

Once it is correctly diagnosed, IgG4-RD responds well to corticosteroid therapy. Natural adjuvant therapies for this disease are chelation of heavy metals, anti-inflammatory diets and immunity-targeted nutraceuticals.

What Are Functional Foods and Novel Foods?

Functional Foods:

Functional food is a food that has been modified to offer an additional function by adding a Canadian Academy of Sports Nutrition functional foods 1new ingredient or more of existing ingredients. Functional food is created with the hope of improving the health benefits the nature has already provided. They are usually enriched with some "bioactive compounds". Functional foods are usually confused with nutraceauticals and novel foods.

Example of functional foods are:

- Eggs with Omega-3 fatty acids.

- Calcium-enriched orange juice.

- Potatoes enriched with anthocyanin.

- Tomatoes enriched with lycopene.

- Cereals fortified with vitamin B12.

Even though the claimed benefits of functional foods have already rendered them quite appealing, whether they can truly affect human health positively or negatively has made them be highly controversial and debateable.

Novel Foods:

Any food that meets any of the following three definitions is called "novel food": Canadian Academy of Sports Nutrition functional foods 2

a) A food or product that does not have a history of safe use as a food.

b) A food that results from a process that has not been previously applied to food.

c) A food that has been modified by genetic manipulation. It is also known as genetically modified foods (GMO foods). GMO foods are also called "Frankenfoods".

Example of novel foods:

a) Foods or products with no history of safe use:

- Eggs with increased levels of lutein

- Camelina oil

- Phytosterols

b) Foods prepared by never-before-applied processes:

- Meats prepared under high hydrostatic pressure.

- Ultraviolet light treated Apple Cider.

c) GMO:

It is estimated that up to 70% of all those products that are currently sold in grocery stores in the USA to have some GMO ingredients. More than 50 GMO crops have been approved for sale in the USA. Even though producing GMO foods facilitate their mechanical harvesting and make them resist insects and pesticide sprays, two major concerns regarding GMO foods are their decreased nutritional values and their potential negative effects on cancers.

Top 12 fruits and vegetables/plants that are highly possible to be GMO:

1) Alfalfa.

2) Beets.

3) Canola.

4) Corn (about 90% of them are GMO).

5) Papaya.

6) Potatoes

7) Soybeans (about 90% of them are GMO).

8) Squash.

9) Sunflower.

10) Tomatoes.

11) Watermelon (seedless).

12 ) Zucchini.
