Atkins Diet Basics

The Atkins diet is not a new phenomenon. The diet first appeared in the late 1970s and has grown popularity in recent years in response to the low-fat diet craze. As dieters had trouble with low-fat plans, they searched for a new solution and Dr. Atkins? New Diet Revolution book found a new audience.

A lot of people have jumped on the Atkins bandwagon and there has been a lot of hype as a result. But what are the basic principles of the Atkins diet?

The Atkins diet is based on a theory of why we get fat. According to Dr. Atkins, the over-consumption of carbohydrates and simple sugars leads to weight gain. The way your body processes the carbohydrates you eat have more to do with your waistline than the amount of fat or calories that you consume. In his book, Atkins outlines a phenomenon called ?insulin resistance.? He theorizes that many overweight people have cells that do not work correctly.

When you eat excess carbohydrates and sugar, your body notices that sugar levels are elevated. Insulin is released from the pancreas in order to store sugar as glycogen in the liver and muscle cells for extra energy later on. However, your body can only store so much glycogen at once. As soon as your body reaches its limit for glycogen storage, the excess carbohydrates are stored as fat. This happens to everyone who eats too many carbohydrates.

However, insulin resistant individuals have an even harder time of using and storing excess carbohydrates. The more insulin that your body is exposed to, the more resistant it becomes. Overtime, the pancreas releases more insulin and cells become insulin resistant. The cells are trying to protect themselves from the toxic effects of high insulin. They create less glycogen and more fat.

As a result, insulin resistant individuals gain extra weight. The carbohydrates get converted into fat instead of energy. Other side effects include fatigue, brain ?fog? (the inability to focus, poor memory, loss of creativity), low blood sugar (which can leads to hypoglycemia), intestinal bloating, sleepiness, depression and increased blood sugar. There is much more than weight at stake when you are insulin resistant.

The remedy for people who are insulin resistant is a diet restricted in carbohydrates. The crux of the Atkins diet is a limitation of carbohydrates in all of its forms. The foods restricted on the Atkins plan include simple sugars (like cookies, sodas and sweets) and complex carbohydrates (like bread, rice and grains). Even carbohydrates that are considered healthy, such as oatmeal, brown rice and whole wheat bread, are restricted on the program.

The diet has you restrict your carbohydrate intake to less than 40 grams a day. This will put your body in a state of ketosis. While in ketosis, your body will burn fat as fuel. According to Dr. Atkins? research, the ketosis state will also affect insulin production and it will prevent more fat from being formed. Your body will begin using your stored fat as an efficient form of fuel, and you?ll lose weight.
Another benefit of the Atkins plan is that ketosis will end your cravings for carbohydrates. If you?ve been living on a carb-heavy diet, you may have found that you simply cannot get enough carbohydrates. With carbohydrate restriction and ketosis comes a reduction in carbohydrate cravings. People who have been on the Atkins diet for some time report that they do not crave carbohydrates as they once did.

Although the initial phases of the Atkins diet are rather strict, the program teaches you to restore balance to your diet in the long run. People who use the diet slowly reintroduce minimal amounts of carbohydrate into their eating until they find a comfortable balance between their health and carbohydrate use.

The basic principles of the Atkins diet have been adapted to many other low-carb diet plans. However, Atkins popularity still remains strong as one of the most effective low-carbohydrate solutions for those who are insulin resistant.

Alcohol And Exercise

On Friday afternoon after you leave work, you probably think about going out and having a few drinks with friends to relax and wind down. Even though you may think you deserve to go out and have a few drinks,there are some things that you should certainly keepin mind.

Like any other day, tomorrow is going to be a day for exercise, and since you are exercising on a regular basis, a few drinks of alcohol won’t really hurt anything, right? Before you decide to rush out to the local bar, there are a few things below that you should think about before you make your choice about going out to drink some alcohol.

Research has proven that even small amounts of alcohol with increase muscular endurance and the output of strength, although these types of benefits are very short lived. After 20 minutes or so, the problems will begin to surface. All of the negative side effects associated with alcohol will easily outweigh any possible benefits that it can have.

No matter how you look at it, alcohol is a poison that can really harm your body if you aren’t careful.

The negative side of alcohol can reduce your strength, endurance, aerobic capability, recovery time, ability to metabolize fat, and even your muscle growth as well. Alcohol will also have an effect on your nervous system and brain. If you use it long term, you can cause severe deterioration of your central nervous system. Even with short term use, nerve muscle interaction can be reduced which will result in a loss of strength.

Once alcohol reaches the blood cells, it can and probably will damage them. With alcohol users, inflammation of the muscle cells is a very common thing. Over periods of time, some of these cells that have been damaged can die which will result in less functional muscle contractions. Drinking alcohol will also leave you with more soreness of your muscles after you exercise, which means that it will take you a lot longer to recuperate.

Alcohol will also have many different effects on your heart and circulatory system as well. When you drink any type of alcohol, you may begin to see a reduction in your endurance capabilities. Anytime you drink, your heat loss will increase, due to the alcohol simulating your blood vessels to dilate. The loss in heat can cause your muscles to become quite cold, therefore become slower and weaker during your muscle contractions.

Drinking alcohol can also lead to digestive and nutrition problems as well. Alcohol cause a release of insulin that will increase the metabolism of glycogen, which spares fat and makes the loss of fat very hard. Due to alcohol interfering with the absorption of several key nutrients, you can also become anemic and deficient with B type vitamins.

Because your liver is the organ that detoxifies alcohol, the more you drink, the harder your liver has to work. The extra stress alcohol places on your liver can cause serious damage and even destroy some of your liver cells.

Since alcohol is diuretic, drinking large amounts can put a lot of stress on your kidneys as well. During diuretic action, the hormones are secreted. This can lead to heightened water retention and no one who exercises will want this to happen.

If you must drink alcohol, you should do it in moderation and never drink before you exercise, as this will impair your balance, coordination, and also your judgement. Think about your health and how you exercise - and you may begin to look at things from a whole new prospective.
