Insulin Response in Low Carbohydrate Diets
With the current popularity of the Atkins diet and similar plans
that emphasize a reduced intake of carbohydrates, it is important to
understand both the theory underlying these diets and the effects of low
carbohydrate consumption on one's health. In particular, it is crucial
that anyone considering such a program understand the effects of low
carbohydrate diets on the body's insulin response, as well as
consequences of low and high insulin levels in the blood. Therefore, the
research on the insulin response to reduced carbohydrate energy bars
contained in the article "Glycemic and insulinemic responses to energy
bars of differing macronutrient composition in healthy adults" by Steven
R. Hertzler and Yeonsoo Kim should be considered.
The basic concept of the Atkins diet is that certain high
carbohydrate foods, such as bread and foods high in sugar, should be
reduced or eliminated from the diet, or at least replaced by foods lower
in carbohydrates. An example of an acceptable low carbohydrate food is
the Atkins Advantage Bar, a low-carbohydrate energy bar that is primarily
protein and fat and which represents the low carbohydrate food studied by
Hertzler and Kim. The scientific theory behind Atkins' proposed shift
from carbohydrate and toward protein and fat is that carbohydrates
theoretically elicit an increased insulin response. In this
context, "increased insulin response" means that the pancreas releases
high amounts of insulin into the bloodstream during the digestion of
carbohydrates. The Atkins theory also holds that there is a link between
high insulin levels in the blood and undesired metabolic effects. Such

...response may suggest that these diets do not achieve this objective. A
probable explanation for the increased insulin response of the low and
moderate carbohydrate bars is that protein and/or fat are substituted for
the removed carbohydrate, and both protein and fat can trigger an
increased insulin response. However, it is more likely that the protein
triggered the insulin response since several studies have demonstrated
that dietary protein and certain amino acids, the building blocks of
protein, are insulinogenic, or insulin inducing.
Thus, participants in a low carbohydrate program may continue to
experience the adverse metabolic conditions of inhibited fat breakdown
and increased blood cholesterol. Additionally, these data suggest that
such diets might not contribute to weight loss or to bettering one's
overall health.
Atkins’ Diet is the most influential way to shed the fat that people want to get rid themselves from. After years and years of no success, some people turn to low-carbohydrate diet, Atkins’ diet, and many of them receive results that will forever change their lives. This diet reprograms the body to fuel on the unnecessary fat storages that many individuals wish would go away. The Atkins’ diet makes the body use fat for energy instead of carbohydrates that cause weight loss. Although low-fat is considered
characterized by high blood glucose and insulin resistance resulting in hyperglycaemia and affects approximately 347 million people worldwide (WHO, 2013). Prevention and treatment often include being physically active, maintaining a healthy body weight, eating a healthy diet and avoiding saturated fat and tobacco use (WHO, 2013). However, studies have recently shown that carbohydrate consumption may be a risk factor for the development of the disease. The quality of carbohydrates has been of particular interest
and Atkins diets aim to achieve lower levels of insulin in the bloodstream. The Zone diet reduces carbohydrates by structuring calorie intake to a 40% carbohydrate, 30% protein, 30% fat ratio. The ratio decreases the amount of carbohydrates consumed, inturn lowering overall insulin levels. The Atkins diet also lowers insulin levels by lowering the quantity of carbohydrates ingested. This four phase diet begins with extreme limitation and gradually allows small amounts of carbohydrates. Though
Comparing the Atkins Diet and the Zone Diet The Atkins and the Zone Diet both view carbohydrates as one of the key nutrients in attaining a reasonable weight. The Atkins Diet reduces one's intake of carbohydrates to the bare minimum substituting them with high fats and proteins. Insulin levels within the body are maintained at a constant level with these foods. But many skeptics do not believe that the Atkins choice of food is very healthy. The Zone Diet believes in more of a balance of
It seems like everywhere you look there is some new diet plan making miraculous promises of weight loss through pills, plans, and formulas. The zone diet is no exception. The zone diet was developed by Dr. Barry Sears in his book," Enter the Zone" which was on the bestseller lists for weeks. The zone promises high energy, weight loss, and no hunger to those willing to follow the simple set of zone rules. It sounds great you say, but does it really work? What is the Zone? The "zone" was first
effects of carbohydrates on blood sugar (glucose) levels. The amount of carbohydrates consumed also affects blood glucose levels and insulin responses. The GI is computed in two ways due to the fact that there are two standards of comparison. The glycemic load of a food is calculated by multiplying the glycemic index by the amount of carbohydrate in grams provided by a food and dividing the total by 100. After a high-glycemic load meal, blood glucose levels rise more rapidly and insulin demand is
Diabetes Diabetes is a lifelong disease that can affect both children and adults. This disease is the sixth leading cause of death in the United States. It claims about 178,000 lives each year. Type one diabetes, also known as insulin dependent diabetes mellitus, usually occurs in people less than thirty years of age, but it also may appear at any age. Diabetes is a very serious disease with many life threatening consequences, but if it is taken care of properly, diabetics can live a normal
energy bars seem to be an easy way to diet without having to hunt down the proper nutritional meals; the meal is already prepared for you in the bar. There are a few questions being raised about this method of dieting however. The issue addressed in this paper is the use of energy bars that either have low carbohydrate levels or that use lower glycemic index carbohydrates. The idea behind using an energy bar of this type for dieting is to lower the levels of insulin in the blood, reduce cholesterol levels
Harmful Effects of the Ornish Diet The Ornish diet, a meal plan that emphasizes the consumption of carbohydrates over fats, is an unsafe plan despite its claims to being a safe and effective way to prevent heart disease1 – a claim only a balanced diet can make. Because the Ornish diet cuts out a large number of foods from a person’s meal, many beneficial nutrients are missing that would normally be in a balanced diet. In addition, recent studies have found that diets containing a larger than recommended
All dietary carbohydrates, from the starch in bread to the sugar in a soda, result in the same physiological effect; being digested and converted into glucose. However, the rate and speed of digestion and blood glucose response are determined by the structure of the carbohydrate. Consuming candy with 10 grams of carbs compared to a carrot with 10 grams of carbs will both be metabolized to glucose and yield the same exact amount of energy. The main difference between the candy and the carrot is the
state soon after breakfast. Let’s now summarise the events of digestion and absorption of fats and carbohydrates that Emma experienced during the two-day period. First of all, digestion is the breakdown of large insoluble food molecules into smaller ones that can be absorbed into the blood. Now Emma’s breakfast meal contained bread and sugar which are carbohydrate rich foods. Therefore, these carbohydrate foods were digestion into smaller particles, along the gastrointestinal tract by amylase enzyme
the number of overweight individuals skyrockets, so too does the number of various diets that Americans are willing to try in their search for the thin standard that our culture idolizes. One of the most popular, and many claim successful, of the conglomerate of diets is the Atkins protein diet, named after its founder and guru Dr. Robert C. Atkins. With more than six million copies in print, Dr. Atkins’ New Diet Revolution proclaims to be "the amazing no-hunger weight-loss plan that has helped millions
Diabetes meltus Defention : Diabetes is a syndrome characterized by metabolic disorder and an abnormal rise in blood sugar concentration caused by insulin deficiency, low insulin sensitivity of insulin, or both. Diabetes leads to serious complications or even premature death; however, diabetics can take certain steps to control the disease and reduce the risk of complications. These steps are summed up in weight reduction, and frequent movement . Epidemiology in UAE : Dr. Abdul Razzaq Al Madani

With anything consumed within this period affecting how the resistance training done previously will impact hypertrophy, naturally one would want to weed out things to limit or to even cut out of a diet.

Many indicate that the adaptive response to the low carbohydrate intake is insulin resistance(Miller, Colagiuri, 1994). A study done by J.C. Brand Miller and S. Colagirui proposes that insulin resistance offered a survival and reproductive advantage during the Ice Ages. This study also proposed that a carnivorous diet would have disadvantaged
