With the popularity of low-carb diets today, most of us have at one time or another considered cutting carbs. In this series of articles we have discussed ‘low-carbing’ and whether or not it’s right for everyone.

In this article we’re going to talk about carbohydrates and how they are stored in the body. Does a large supply of excess carbs make us fat?

Many people believe that only dietary fat will lead to body fat. False! Actually, eating more calories than your body needs to perform daily activities and daily metabolism is what causes body fat. It is as simple as putting 20 gallons of gas in a 15 gallon gas tank…..the excess must go somewhere. In the case of human nutrition, the excess is stored as fat.

Just as excess protein can be stored as body fat, excess carbohydrate can be stored as body fat. Unfortunately for the American public, our consumption of simple carbohydrates has skyrocketed over the last ten years! Too many of us took the popularity of the low-fat and fat-free diets as an excuse to fill up on empty carbo-calories. After all, it’s okay to eat the entire package of licorice since it’s all fat free….right? Again, False!

Carbohydrates that the body cannot use are stored as body fat, plain and simple. Carbohydrates usually are ingested in the forms of polysaccharides (starches), disaccharides (sucrose and lactose) and monosaccharides (glucose and fructose). Essentially what occurs in the digestive process is a breakdown of the polysaccharides and disaccharides to the monosaccharides. The primary site of digestion is the small intestine, where the monosaccharides are then absorbed into the blood. Of the three monosaccharides, glucose is of most importance to human physiology. This is called blood sugar. Fructose and galactose are converted to blood glucose either in the intestinal wall or the liver.

A high-carbohydrate meal will lead to a rapid increase in the blood sugar level, usually within an hour. Naturally, the higher the food is on the glycemic index (refined sugars), the higher the blood sugar level will rise. The maintenance of a normal blood sugar level is very important for proper metabolism. The human body regulates blood sugar levels by a hormone called insulin. The rises in blood sugar levels stimulate the pancreas to secrete the hormone insulin into the blood. Insulin then facilitates the uptake and utilization of blood sugar by various tissues in the body, most notably the muscles and adipose tissue.

The fate of blood sugar is dependent on many factors, with exercise being one of the most important.

1) Blood sugar may be used for energy, particularly by the brain and other parts of the nervous system.

2) Blood sugar may be converted to either liver or muscle glycogen. Liver glycogen may then be later converted to blood sugar. Muscle glycogen is, for the most part, locked into the muscle cell once it enters, where it is converted to energy.

3) Blood sugar may be converted to and stored as fat in the adipose tissue. This situation occurs when the dietary carbohydrate, in combination with caloric intake of other nutrients, exceeds the energy demands of the body, and the storage capacity of the liver and muscles for glycogen.

4) Some blood sugar also may be excreted in the urine if excessive amounts occur in the blood, because of rapid ingestion of simple sugars.

So, what happens if we don’t consume enough carbohydrates? Because the carbohydrate stores in the body are rather limited, and because blood sugar is normally essential for optimal functioning of the central nervous system, it is important to be able to produce blood sugar or glucose internally if the stores are depleted by starvation or a zero-carbohydrate diet. This process is called gluconeogenesis, meaning the formation of glucose. In this process, protein is converted to glucose, and fat is converted to glucose by breaking down glycerol in the liver. The by-products of carbohydrate metabolism, lactate and pyruvate, may also be converted back to glucose in the liver.

With this understanding of how carbohydrate is metabolized in the body, it is clear that low-carb or no-carb diets may lead to decreased levels of energy.

Low-carb diets, however, have been proven to take off the weight. In some cases, weight loss has been dramatic when the subjects abruptly switched to a no-carb diet. Such rapid weight loss is attributed to water loss. Low carbohydrate intake depletes liver and muscle glycogen (stored sugars) and water molecules linked to these sugars. This depletion triggers a drop in body weight.

Especially during the introduction phase of a low-carb diet (2 weeks), the dieter is encouraged to eliminate virtually all carbohydrates from the diet. Even a slight intake of high glycemic foods during this phase would cause immediate weight gain by rebuilding glycogen stores.

Because carbohydrate is the body’s preferred fuel source, this first phase of the diet would most certainly challenge exercise enthusiasts.

So, is the low-carb lifestyle right for you? Maybe. We hope that this series of articles has helped you understand low-carb diets and their potential impact on the body.

The South Beach Diet is one of the most popular diets in decades. All over the world, people are taking off weight by stripping carbs and, in the process, learning to eat healthier meals. One of the true beauties of South Beach is that it teaches you a whole new way of eating for a healthier, happier lifestyle. Eating healthy the South Beach way requires an adjustment in your cooking styles, too, though. Once you learn to cook low-carb, you’ll find it easier to maintain your new weight and your new healthier lifestyle. Here are some tips to help you put it all together.

1. Invest in a good cookbook.

The third phase of the South Beach diet is a lifetime maintenance plan that lets you eat a wide variety of healthy foods. If your recipe repertoire was based on high-fat meals with creamy sauces and processed foods, you’ll need to build up a stock of new recipes. The South Beach Diet book is a good start. It contains a lot of easy to cook recipes that will get you started on building a new repertoire of healthy meals. You’ll also find dozens of South Beach cookbooks on the market that will give you some ideas on the best ways to put your new-found food savvy to use.

2. Think fresh!

Processed foods are the very antithesis of healthy low-carb eating. Even processed meats are packed with fillers that add in carbs and calories without offering anything in the way of nutrition. Try to shop the outside aisles of the supermarket – fresh fruits and veggies, meats and dairy – and avoid all the filler meals in between.

3. Learn simple cooking methods.

Learning to cook the South Beach way is surprisingly simple – a lot simpler than the techniques you probably use for cooking now. Steaming, poaching, braising, roasting and grilling involve very little prep time. If a recipe calls for dredging in flour or dusting with breadcrumbs, throw it out. You’ll learn a whole new appreciation for real, whole foods when you cook them simply.

4. Color your plate pretty.

A healthy plate is full of vibrant, brilliant colors. When you prepare a plate for yourself, think in color. Deep green, dark orange and bright red vegetables are low in healthy carbohydrates, minerals and vegetables. White potatoes, rice and breads are not. Your best bet is to eat your veggies when they’re at their peak of color – before overcooking robs them of their minerals and vitamins.

5. Spice it up!

Spices are a great way to brighten up flavors in your foods. There’s a whole world of spices at your fingertips, and learning to use them can really wake up your plate and your palate. Learning about the spices used in various regional cuisines can help you turn a meal from bland to POW with just a few shakes of the spice bottle. Some spices and spice combinations to try are:

Curry isn’t just for Indian food anymore. A sprinkle of curry (use a light hand!) can really wake up the flavor in a fresh fruit salad, especially when you add a dab of vanilla.
Cinnamon is an unusual and delicious spice addition to chicken dishes.
Lemon grass oil adds a tart edge to salads and vegetables. Just a dash added to the olive oil when you sauté chicken also brightens the flavor and really wakes up your taste buds.
Rosemary gives everything an earthy, sharp flavor that is the perfect foil for poultry and pork.

6. Add a little garnish to your life.

Garnishes are more than just pretty things on your plate. Fresh herbs, slices of fruit and strips of raw vegetable are more than a treat for your eyes. They add a healthy balance to your diet as well. Choose edible garnishes – a slice of lemon can be squeezed over fish or chicken to brighten flavors, for instance.

 

The most important things to remember about cooking low-carb for the long term are these:
Skip the white foods. They’re almost always processed
Cook simply. Cooking low carb is usually quick, easy and uncomplicated.
Use olive oil for dressings and sautéing.
Get colorful. The more color there is on your plate, the healthier your meal will be.

I’m diabetic so I have to have low carb bread, but everything I have made thus far tastes horrible. Any ideas?

Unless you’ve been living in a cave for the last few months, you’ve probably noticed that low-carb mania is sweeping the nation. Food manufacturers are in a heated race to see who can get the most low-carb fare into the grocery stores, and every advertiser worth their salt is emphasizing the low-carb message. Popularized by the late Dr. Atkins, the low-carb diet has taken the nation by storm and was by far the biggest trend of 2004.

So, does the low-carb diet work? Anecdotal evidence and recent studies both conclude that following a strict low-carb diet will in fact help you lose weight. Serious questions remain, however, and must be addressed before fully embracing the low-carb lifestyle. Some of these questions include:

* What are the long-term effects (10-20 years) of low-carb eating?

* Can you stick with the low-carb diet, or will your love for carbohydrates keep you cheating and frustrated?

* How does a low-carb diet mix with exercise? In particular, what impact does it have on your muscle?

* Have you read the materials on the low-carb diet, or are you just following the second-hand information you heard from a co-worker?

In this series of articles we will attempt to address these issues.

Real fitness experts emphasize that you should make changes to your diet that you can stick with for the long term. All too often, people start on a new “diet” and willpower their way to weight loss. They don’t enjoy it, mainly because their “diet” is telling them they can’t eat the foods they love. BOOM They’re off the diet. Perhaps a few months later they try another diet, just to find that it is also too restrictive and BOOM they’re off again. This yo-yo dieting takes a toll on the body, often leading to lost muscle mass and even worse a feeling of failure.

For any “diet” to work, it has to be created in such a way that you can live with it. Life is simply too short to be absolutely miserable, and trying to willpower yourself into a “diet” that you can’t stick with is a sure path to misery.

So, should you start a low-carb diet? That’s the million-pound question! And the answer is…..drum roll please…..maybe! If you think you can stick with it, and if you take the time to read about it and get the facts, and if you discuss it with your doctor, and if you know what you are getting into, and if you have the support of your family, then maybe the low-carb diet is right for you.

Why not just a simple ‘yes’ or ‘no’? Because everybody is different and no single plan is going to work for everyone. Weight Watchers, Jenny Craig, Slim-Fast, the Atkins Diet, the South Beach Diet, and hundreds of other plans have all helped people, but not one of them has helped everyone.

What’s important to realize is that you must discover your own nutritional plan: one that works for you.

And finally, a reminder to exercise must be shouted from the gym floor! No matter what nutritional approach you take, all of the experts recommend that you exercise on a regular basis. Think about it: there are hundreds of diet plans out there in the world today, and many of them offer conflicting information, but the one thing that they all have in common is that they strongly encourage you to exercise. So although the experts may disagree on what you should eat, they do agree on what you should do: exercise!

 Following a gluten free, low carb diet can seem a daunting prospect. But with some careful planning gluten free, low carb recipes can become second nature. This article gives ten top tips for making them easier.
#1 – Planning is key
.Ensure that you always plan your meals a few days in advance. Make lists of all the ingredients that you’re going to need for your recipes.
#2 – The perimeter of the supermarket is your friend.
The safe foods tend to be found around the edge of the supermarket. Fresh vegetables, fruit, meat, fish and dairy can usually be found here.
#3 – Don’t just shop in the supermarket.
Learn to look for your foods in health food stores, farmer’s markets and online.
#4 – Plain foods are best.
Whether it’s fresh, frozen or tinned, your safest bets are with food that isn’t processed or covered in sauce and seasoning.

#5 – Always read the label.

Note brands of specific items that you know are safe and stick to these. But keep checking these labels periodically as ingredients do change.

#6 – Keep an eye on the oven.

Gluten free baking needs to be more closely monitored as it is more sensitive to being under or over cooked.

#7 – Cover your baked goods.

Your food will dry out much quicker, so make sure that it’s covered to keep the moisture inside.

#8 – Freeze baked goods for a better texture.

Divide up into portions and freeze it once it has cooled.

#9 – Cook more.

Whenever you are cooking, try to always cook for more people than you are feeding. Bag the extra, label it clearly and freeze it. This enables you to build up a store of healthy fast food that you can use when you don’t have time to cook.

#10 – Practice.

Use these tips and learn from your mistakes, but above all practice! In no time gluten free, low carb recipes will become as easy as pie!
