Eating Low Glycemic Carbohydrates Is Important For Losing Weight

Maintaining a steady blood sugar level is very important component of your dieting effort. While your body breaks down all digestible carbohydrates into blood sugar, some are converted into blood sugar faster than others. Thus, some carbohydrates cause a spike in your blood sugar level which causes you to feel hungry faster and to crave more sugary foods. While other carbohydrates are converted into blood sugar more slowly leveling out you blood sugar resulting in less hunger and less food cravings.

For this reason, the Glycemic Index (GI) was developed to classify how quickly your body converts carbohydrates into blood sugar as compared to pure glucose. Glucose has a GI of 100 and all other carbohydrate based foods are ranked against it. Foods with a score of 70 or more are defined as having a high GI while those with a score of 55 or less are considered as low.

Eating lots of food with a high GI causes spikes in your blood sugar level which can lead to many health issues such as type 2 diabetes, heart disease, and obesity. While eating low GI foods causes your blood sugar level to stay even thus, keeping your energy level balanced and causing you to fill fuller longer between meals. The following are some additional benefits of eating low GI carbohydrates.

· Helps you to lose and manage weight your weight.
· Increases your body's sensitivity to insulin.
· Decreases your risk of developing type 2 diabetes.
· Reduces your risk of heart disease.
· Improves your blood cholesterol levels
· Reduces hunger and keep you fuller for longer.
· Helps you prolong physical activity.
· Helps you to re-fuel your carbohydrate stores after exercise.

The GI is very interesting because some foods that you intuitively think would have a high rating do not. For instance, fructose which is fruit sugar has a minimal effect on blood sugar while white bread and French-fried potatoes are nearly converted to blood sugar as fast as pure glucose. In other words, you can’t classify foods as having a high or low GI according to the sweetness of taste. Many factors affect a foods GI such as:

· Processing: Grains that have been milled and refined have a higher GI

· Type of starch: Starches come in many different configurations. Some are easier to break into sugar  molecules than others. For example, starch in potatoes is digested and absorbed into the bloodstream relatively quickly.

· Fiber content: The sugars in fiber are linked in a way that is hard for your body to break down. Thus, the more fiber a food has, the less digestible carbohydrate, and consequently the less sugar it can deliver into your blood stream.

· Fat and acid content: The more fat or acid a food contains, the slower its carbohydrates are converted to sugar and absorbed into your bloodstream.

· Physical form: Finely ground grain is more rapidly digested, and so has a higher GI than more coarsely ground grain.

The basic technique for eating the low GI way is simply a "this for that" approach - i.e., swapping high GI carbohydrates for low GI carbohydrates. You don't need to count numbers or do any sort of mental arithmetic to make sure you are eating a healthy, low GI diet. Follow these easy to implement suggestions.

· Use breakfast cereals based on oats, barley and bran
· Use breads with whole-grains, stone-ground flour, sour dough
· Reduce the amount of potatoes you eat
· Enjoy all other types of fruit and vegetables
· Use brown rice
· Enjoy whole-wheat pasta and noodles
· Eat plenty of salad vegetables with a vinaigrette dressing

Strength Training Over 50; The Benefits

While I can personally attest to the benefits of strength training in my life, below is additional information from the Fitness Professional's Guide to Strength Training Older Adults by Thomas R Baechle, and Dr. Wayne L Westcott.  After reading this, you will not have any doubts about the value of incorporating a regular strength training program has in your life.

Research indicates that older adults may experience many health-related benefits from a sensible program of strength exercise that is performed at a relatively high effort level.  Some of the possible benefits include the following:

  • Better body composition with up to 4 pounds more lean weight, and 4 pounds less fat weight after 2 months of regular strength training.
  • Increased metabolic rate of up to 7 percent higher resting metabolism and up to 15 percent greater daily calorie requirements after 3 months of regular strength training.
  • Decrease low-back discomfort, as evidenced by approximately 80 percent of patients reporting less or no pain after 3 months of specific low-back strengthening exercise.
  • Reduced arthritic pain, as indicated by subjective ratings of symptoms in strength trained adults who have arthritis.
  • Increased bone mineral density that minimize age related bone loss and offer protection against osteoporosis.
  • Enhanced glucose utilization that may reduce the risk of type 2 diabetes.
  • Faster gastrointestinal transit that may reduce the risk of colon cancer and other motility disorders of the gastrointestinal system.
  • Reduced resting blood pressure, including lower diastolic readings and lower systolic readings.
  • Improved blood lipid profiles, including lower levels of LDL cholesterol and higher levels of HDL cholesterol.
  • Improved postcoronary performance resulting from higher muscular functional capacity and lower cardiovascular stress from routine and unplanned physical activity.
  • Enhanced self-confidence, as reported by previously sedentary men and women following 2 months of regular strength training.
  • Relieved depression in older adults clinically diagnosed with mild to moderate depression.

Build Your Fitness Program Around Strength Training If You Are Over 50

I'm in my 50s and I've spent over 20 years in the health and fitness industry as a personal trainer so, I believe I'm qualified to say this "If you are over 50 and you neglect to make strength training the major emphasis of your fitness program you're making a big mistake".

Building and maintaining muscle is key in staying health and fit as you age and strength training is the most effective means for accomplishing this.  Beginning as early as your 30s, if you are inactive you begin to lose muscle mass as a natural process of aging called sarcopenia.  You can lose as much as a pound to a pound and a half of muscle each year beginning in your 40s, and this process accelerates with age if left unabated.

Losing muscle is detrimental to your long term health and fitness in two ways.  One, your metabolism decreases as you lose muscle causing your body to store more fat and consequently increasing your risk of obesity and associated metabolic syndrome.  Two, you lose strength along with muscle loss which leads to an increased risk of falls, broken bones, and a loss of independence.

Building and maintaining your muscle helps to:
  • Strengthen and improve your bone density
  • Decrease your risk for developing type 2 diabetes
  • Improve your balance thus, reducing your risk of falls
  • Strengthen your joints thus, reducing the pain of arthritis 
  • Lose weight more easily
  • Improve your mood
  • Improve your self-image
  • Improve your sleep
  • Perform your everyday activities more easily
While regular cardiovascular activities should be an important part of your fitness routine, it does not build nor maintain your muscle mass.  Strength training is the most proven way to build and maintain lean, and healthy muscle.  You should strength train 2 to 3 times each week in which target all your major muscle groups.  I suggest you seek a nationally certified personal trainer to custom design a strength training program for you.  You can also download my Beginner, Intermediate, and Advanced Strength Training Programs for Over 50 by following this link: Forever Fit and Firm.

Do You Know Fat is Good for You?



Fat has also taken a bad rap over the years, but it is very essential to your health and well-being. Like in all things, balance and moderation is the key.


For decades, the mantra for healthy eating has been “eat a low-fat, low-cholesterol diet.” Touted as a way to lose weight and prevent heart disease and other chronic conditions, millions of people have followed this advice. Seeing a tremendous marketing opportunity, food companies re-engineered thousands of foods to be low-fat or fat-free. The low-fat approach to eating may have made a difference for the occasional individual, but as a nation, it has neither helped us control our weight nor has it helped us become healthier. In the 1960s, fats and oils supplied Americans with about 45 percent of their calories. About 13 percent of the population was obese and less than one percent had type 2 diabetes. Today, Americans take in less fat, getting about 33 percent of calories from fats and oils; yet 34 percent of the population is obese, and eight percent has diabetes (mostly type 2)



Research has shown that the total amount of fat in your diet is not linked to weight or disease. What actually matters is the type of fat in your diet. Trans fats and saturated fats increase your risk of cardiovascular disease, while monounsaturated and polyunsaturated fats do just the opposite. But then you ask, “What about cholesterol in food?” The answer is, for most people the mix of fats in their diets influences cholesterol in their bloodstreams far more than cholesterol in food.

Almost all foods contain some fat. Even foods like carrots and lettuce contain small amounts of fat. That’s a testament to how important fats are for your health and well-being. Fat provides a terrific source of energy for your body as well as a great depot for storing it. It is an important part of cell membranes, helping govern what gets into and out of your cells. Your body uses cholesterol as the starting point to make estrogen, testosterone, vitamin D, and other vital compounds. Fats are also biologically active molecules that can influence how your muscles respond to insulin. Also, different types of fats can fire-up or cool down inflammation in your body.

 

You can basically break the fats in your diet into three categories; good, bad, and very bad.
 Good Fats

Unsaturated fats are called good fats because they can improve blood cholesterol levels, ease inflammation, stabilize heart rhythms, and play a number of other beneficial roles. Unsaturated fats are predominantly found in foods derived from plants, such as vegetable oils, nuts, and seeds. They are liquid at room temperature. 

Furthermore, there are two types of unsaturated fats: monounsaturated and polyunsaturated. Monounsaturated fats are found in high concentrations in canola, peanut, and olive oil, in avocados, nuts like almonds, hazelnuts, and pecans, and seeds such as pumpkin and sesame. Polyunsaturated fats are found in high concentrations in sunflower, corn, soybean and flaxseed oil. They also are found in foods such as walnuts, flaxseeds and fish.

Research has shown that replacing carbohydrates in your diet with good fats reduces harmful levels of LDL and increases protective HDL in your bloodstream. A randomized trial called the Optimal Macronutrient Intake Trial for Heart Health showed that replacing a carbohydrate-rich diet with one rich in unsaturated fat—predominantly monounsaturated fats—lowers blood pressure, improves lipid levels, and reduces the estimated cardiovascular risk.

Bad Fats

Saturated fats are called bad fats because they increase your total cholesterol level by elevating harmful LDL. Your body can produce all the saturated fat that it needs, so you don’t have to get any from your diet. In the U.S. and other developed countries, saturated fats come mainly from meat, seafood, poultry with skin, and whole-milk dairy products. A few plant sources, such as coconuts and coconut oil, palm oil and palm kernel oil, also are high in saturated fats.

As a general rule, it’s good to keep your intake of saturated fats as low as possible. Saturated fats are found in many foods, including vegetable oils (that are mainly unsaturated fats), so you cannot completely eliminate them from your diet. Because red meat and dairy fat are the main sources of saturated fats for most people, minimizing them in your diet is the primary way to reduce your intake of saturated fat.

Very Bad Fats

Trans fatty acids, more commonly known as trans fats, are made by heating liquid vegetable oils in the presence of hydrogen gas—a process called hydrogenation. Partially hydrogenating vegetable oils makes them more stable and less likely to spoil. It also converts the oil into a solid which makes transportation easier. Partially hydrogenated oils can also withstand repeated heating without breaking down, making them ideal for frying fast foods. This is the reason partially hydrogenated oils have been a mainstay in restaurants and the food industry.

Trans fats are worse for cholesterol levels than saturated fats because they raise bad LDL and lower good HDL. They also increase inflammation, an over-activity of the immune system that is associated with heart disease, stroke, diabetes, and other chronic conditions. Even small amounts of trans fats in your diet can have harmful health effects. For every extra two percent of daily calories from trans fat (the amount in a medium order of fast food French fries) the risk of coronary heart disease increases by 23 percent. It is estimated that eliminating trans fats from the U.S. food supply would prevent between six and 19 percent of heart attacks and heart attack-related deaths (more than 200,000) each year.

Recommendations for Fat in Your Diet

Are you confused at this point about the type of fats and their varied effects on your health? If so, remember to replace the bad fats in your diet with the good fats. Here are some suggestions to help you limit the bad fats in your diet.

·        Eliminate trans fats from partially hydrogenated oils. Check food labels for the presence of trans fats and avoid fried fast foods.
·        Limit your intake of saturated fats by cutting back on red meat and full-fat dairy products. When possible replace red meat with poultry, fish, beans, and nuts. Also, try switching from whole milk and other full-fat dairy foods to lower-fat versions.
·        Use liquid vegetable oils rich in polyunsaturated and monounsaturated fats in place of butter in your cooking and at the table.
·        Eat one or more sources of omega-3 fats every day. Good sources are fish, walnuts, canola or soybean oil, ground flax seeds and flaxseed oil.

Make Strength Training the Foundation of Your Fitness Program

It's the first of the year and I already see my gym flooded with people eager to get healthy and fit for the New Year.  Most of the new comers spend most of their time on the cardio equipment, then they spend a few minutes lifting weights, and then they go home.

While cardio is a very important component of your fitness program, it shouldn't be where you spend the majority of your time in the gym.  I recommend you build your fitness program around strength training, also known as weight lifting and here's why:

Strength Training builds and helps to maintain your muscle mass.  Muscle tissue is always active and thus burns calories even when you are at rest.  Thus, by building and maintaining your muscle mass you  increase your resting metabolism, which means you burn more calories even while you are sleeping.

Muscle is key to long-term weight loss and body fat reduction.  As a personal trainer I often hear statements like this "ever since I tuned 40 I can't seem to lose weight and I've developed these areas of fat that I can't get rid of either."  Muscle loss is the primary reason for this scenario.  Beginning as early as your 30s you start to naturally lose muscle mass, and this process accelerates with age if you don't do anything to stop or slow it down.  As I previously mentioned, muscle is that active part of your body that burns calories even when you are resting.  Thus, as you lose your muscle mass your metabolism decreases, and consequently your calorie burning capacity also decreases.  Additionally, body fat is the fuel of choice for your muscles while you are at rest, and also for low intensity activities such as casual walking, cleaning house, and yard work.

Strength training increases your bone strength and makes your joints stronger.  Regular strength training has been proven to decrease the risk of developing osteoporosis, and also to make the activities of daily life easier to perform.

Strength training helps reduce blood sugar, and thus, reduces the risk for developing Type 2 diabetes.  Strength training plays a particular role to in reducing blood sugar and improving insulin sensitivity because when you lift weights the main fuel used is that stored as muscle glucose. Building extra muscle also provides a larger storage area for glucose, so the combination of these two factors -- increased muscle and regular emptying of these muscle stores -- improves the body's glucose processing, a factor crucial in preventing and managing type 2 diabetes.

Hopefully you can see why I think strength training should be the foundation of your fitness program.  If you are new to weight lifting, I suggest you find a nationally certified fitness professional to help you develop a strength training program, and to teach you the proper form and lifting techniques.

Eating Some Fat is Part of a Healthy Diet

Fat has taken a bad rap over the years but, it is very essential to your health and well being.  “Eat a low-fat, low-cholesterol diet” has been the mantra for healthy eating for decades now. Touted as a way to lose weight and prevent heart disease and other chronic conditions, millions of people have followed this advice. Seeing a tremendous marketing opportunity, food companies re-engineered thousands of foods to be lower in fat or fat free. The low-fat approach to eating may have made a difference for the occasional individual, but as a nation it has not helped us control our weight or become healthier. In the 1960s, fats and oils supplied Americans with about 45 percent of their calories and about 13 percent of the population was obese and less than 1 percent had type 2 diabetes. Today Americans take in less fat, getting about 33 percent of calories from fats and oils, yet 34 percent of the population is obese and 8 percent has diabetes (mostly type 2).

Your body packages fat and cholesterol into tiny protein-covered particles called lipoprotein in order to get them into your blood stream. Some of these lipoproteins are big and fluffy, and others are small and dense. However, the most important ones to remember for your health and well-being are low-density lipoproteins, high-density lipoproteins, and triglycerides as explained below.

Low-density lipoproteins (LDL) carry cholesterol form your liver to the rest of your body. Your cells latch onto these particles and extract fat and cholesterol from them. When there is too much LDL cholesterol in your blood, these particles can form deposits in the walls of your coronary arties and other arties throughout your body. These deposits, called plaque can cause your arties to narrow and limit blood flow resulting in a heart attack or stroke. Thus LDL cholesterol is called your bad cholesterol.

High-density lipoprotein (HDL) scavenge cholesterol from your bloodstream, from your LDL, and from your artery walls and ferry it back to your liver for disposal. Thus HDL cholesterol is referred to as your good cholesterol.

Triglycerides make up most of the fat that you eat and that travels through your bloodstream. Triglycerides are your body’s main vehicle for transporting fats to your cells and thus, are very important for your good health. However, an excess of triglycerides can be unhealthy.

The type of fat your diet determines to a large extent the amount of total and LDL cholesterol in your bloodstream. Cholesterol in food matters too, but not nearly as much. You can basically break the fats in your diet into three categories; good, bad, and very bad.

Good Fats

Unsaturated fats are called good fats because they can improve blood cholesterol levels, ease inflammation, stabilize heart rhythms, and play a number of other beneficial roles. Unsaturated fats are predominantly found in foods from plants, such as vegetable oils, nuts, and seeds. They are liquid at room temperature.

A randomized trail known as the Optimal Macronutrient Intake Trial for Heart Health showed that replacing a carbohydrate-rich diet with one rich in unsaturated fat, predominantly monounsaturated fats lowers blood pressure, improves lipid levels, and reduces the estimated cardiovascular risk.

Saturated fats are called bad fats because they increase your total cholesterol level by elevating your harmful LDL. Your body can make all the saturated fat that it needs, so you don’t need to get any in your diet. In the US and other developed countries saturated fats come mainly from meat, seafood, poultry with skin, and whole-milk dairy products. A few plant sources are also high in saturated fats, such as coconuts and coconut oil, palm oil, and palm kernel oil.

As general rule it’s a good idea to keep your intake of saturated fats as low as possible. Saturated fats are a part of many foods, including vegetable oils that are mainly unsaturated fats, so you can’t totally eliminate them from your diet.
