What is Diet?

- The word diet comes from the Greek work, diata. This meaning of diet acknowledges that all
parts of our lifestyle and our relationships impact on health and wellbeing. Diet usually describes
foods that is low in calories. It also refers to the food and drink a person consumes daily and the
mental and physical circumstances connected to eating. It is regulating one’s food intakes for the
purpose of improving one’s physical condition.

Purpose of Diet?

- Diet is to maintain good health, to prevent chronic diseases, and overall sense of wellbeing and
vitality. It can help to ward off numerous diseases and health complications, as well as help
maintain a healthy body weight, provides energy, allow better sleep, and improve brain function.

Benefits of Diet?

- Control Body Weight - Eating a healthy variety of nutrient-dense foods leaves less room for
those calorie-dense foods that typically lead to weight gain. Eating carbohydrates like whole
grains, oats, vegetables, fruits, legumes, and quinoa that have a low glycemic index will allow the
body to stay fuller over a longer period of time. These complex carbohydrates break down and
release into the blood stream over an extended period of time preventing triggers in the brain to
crave simple sugary snacks.
- Fight off Disease - When eating a balanced diet, essential nutrients will produce and help
maintain key germ-fighting cells in the immune system, and greatly improve vascular function.
The immune system relies heavily on blood flow, so better vascular function will help provide
disease fighting cells to areas of need quickly.
- Have More Energy - The food we eat has a tremendous impact on the energy we have
throughout the day. Eating well keeps our energy on a relatively level base from morning until
night. Proteins can help provide satiety much more effectively then processed foods or simple
carbohydrates.
- Sleep Better - It is important to not overeat at nighttime, which many people are guilty of due to
poor eating habits during the day. Making sure meals are spaced out effectively becomes an
important rule once again.
- More Brain Power - We have an opportunity to keep it healthy and functioning at a high level
based on our eating habits. Omega 3 fatty acids provide a number of important benefits, such as
improved memory and the ability to learn. They also help fight against debilitating mental
disorders, for example, depression, dementia, and schizophrenia.
Types of Diet

- The Paleo Diet - This is a natural way of eating, one that almost abandons all intake of sugar.
The only sugar in a Paleo diet comes from fruit. A Paleo diet consists of fish, fowl, vegetables,
fruits, nuts, oils, sweet potatoes, eggs and meat, so long as that meat is grass-fed and not grain-
fed.
- The Vegan Diet - This diet is a form of a vegetarian diet as it eliminates meat and animal
products. One of the primary effects of this diet is that it reduces the intake of cholesterol and
saturated fat. It takes some planning, but if a vegan diet is rationed out properly, it can have many
positive effects.
- Low-Carb Diet - The primary aim of the diet is to force your body to use more fats for fuel
instead of using carbs as a main source of energy. Low-carb diets emphasize unlimited amounts
of protein and fat while severely limiting your carb intake. When carb intake is very low, fatty
acids are moved into your blood and transported to your liver, where some of them are turned
into ketones. Your body can then use fatty acids and ketones in the absence of carbs as its
primary energy source.
- The Dukan Diet - The Dukan diet is a high-protein, low-carb weight loss diet split into four
phases — two weight loss phases and two maintenance phases. How long you stay in each phase
depends on how much weight you need to lose. Each phase has its own dietary pattern. The
weight loss phases are primarily based on eating unlimited high-protein foods and mandatory oat
bran. The other phases involve adding non-starchy vegetables followed by some carbs and fat.
Later on, there will be fewer and fewer pure protein days to maintain your new weight.
- The Ultra-Low-Fat Diet - An ultra-low-fat diet restricts your consumption of fat to under 10%
of daily calories. Generally, a low-fat diet provides around 30% of its calories as fat. Studies
reveal that this diet is ineffective for weight loss in the long term. Proponents of the ultra-low-fat
diet claim that traditional low-fat diets are not low enough in fat and that fat intake needs to stay
under 10% of total calories to produce health benefits and weight loss.
- The Atkins Diet - The Atkins diet is the most well-known low-carb weight loss diet. Its
proponents insist that you can lose weight by eating as much protein and fat as you like, as long
as you avoid carbs. The main reason why low-carb diets are so effective for weight loss is that
they reduce your appetite. This causes you to eat fewer calories without having to think about it.
- The HCG Diet - The HCG diet is an extreme diet meant to cause very fast weight loss of up to
1–2 pounds (0.45–1 kg) per day. Its proponents claim that it boosts metabolism and fat loss
without inducing hunger. HCG (human chorionic gonadotropin) is a hormone present at high
 levels during early pregnancy. It tells a woman's body it's pregnant and maintains the production
of hormones that are important for fetal development. It has also been used to treat fertility issues.

- The Zone Diet - The Zone Diet is a low-glycemic load diet that has you limit carbs to 35–45% of
daily calories and protein and fat to 30% each. It recommends eating only carbs with a low
glycemic index (GI). The GI of a food is an estimate of how much it raises your blood glucose
levels after consumption. The Zone Diet was initially developed to reduce diet-induced
inflammation, cause weight loss, and reduce your risk of chronic diseases (89Trusted Source).
- Intermittent Fasting - Intermittent fasting cycles your body between periods of fasting and
eating. Rather than restricting the foods you eat, it controls when you eat them. Thus, it can be
seen as more of an eating pattern than a diet.
