Glycemic Index

Why the The Glycemic Index (GI) is of little significance


The Glycemic Index (GI) has received a lot of attention lately as the standard for determining "good" carbs vs. "bad" carbs. But it’s actually quite misleading.

The GI ranks foods based on how much the blood sugar increases after it is consumed. The higher the number on the GI scale, the greater the increase in blood sugar. When blood sugar goes up, insulin levels rise. And because high levels of insulin are associated with increased fat storage and suppressed fat burning, it is said that eating high GI foods can make you fatter than eating low GI foods.

However, the mistake in adhering to the GI for your carb choices is this:
The index is based on those carbs being eaten by themselves and on an empty stomach, something you should never do if you want to lose fat. You always want to combine a protein source with your carbs, and you want to eat frequently throughout the day.

For example, a potato has a very high GI, but if you combine it with a chicken breast, the GI of the combo is much lower than the potato by itself. Rice cakes also have a high GI. But if you spread a little peanut butter on them, the fat slows the absorption of the carbs, thereby lowering the GI of the combination.

So, when you combine a protein source with your carbs at every meal, and you eat frequently throughout the day, like you should for fat loss, the GI becomes very insignificant.

So, instead of using the Glycemic Index as the criteria for choosing your carbs, as so many people do, simply choose natural carbs over those that are processed.

Natural carbs are those picked from the ground or a tree: fruits and vegetables, oatmeal, yams, brown rice, potatoes, beans, lentils, yams, etc.

Processed carbs are “man-made,” and you want to especially limit those that are white and refined, such as the pasta, white bread, bagels, crackers, white rice, pretzels, chips, and refined sugars.

Key points to remember:

  1. The index is based on those carbs being eaten by themselves and on an empty stomach, something you should never do if you want to lose fat.
  2. When you combine a protein source with your carbs at every meal, and you eat frequently throughout the day, like you should for fat loss, the GI becomes very insignificant .
  3. Choose natural carbs over those that are processed (“man-made”).

Veggies

Vegetables – Extremely Important for Fat Loss


Veggies are perfect for those who want to lose fat. If there’s any one type of food that's the most helpful to fat loss, it’s vegetables. Here’s why:

1. They are very low in calories. You’d have to eat 5 bags of spinach, or 3 heads of broccoli, to equal the calories of just 1 cup of pasta or 1 tiny tablespoon of butter. So, you absolutely do not have to go hungry on tiny portions when you load up on veggies. In fact, it’s almost impossible to eat too many.

2. Here’s the next point about veggies. They are high in fiber. This is both good for your digestion and good for weight loss as that fiber expands in the stomach, making you feel full and satisfied. A bowl of spinach has 8 grams of fiber, about 1/3 of your daily requirement. Broccoli, green peas, and other green leafy vegetables are also good sources of fiber.

3. The third reason fibrous carbs are perfect for fat loss is because they have almost NO adverse affects on blood sugar levels. While it’s still a good idea to balance veggies out with a protein source, even eaten alone they’re okay because they don’t cause an increase in insulin.

4. And finally, they’re loaded with vitamins and minerals and other very beneficial nutrients, such as antioxidants and phytonutrients, that will help you look and feel better, fight off disease, and improve your overall health.

So if fibrous carbs are so great, so perfect for fat loss, why shouldn’t we eat them at every meal? That’s a very good question. And it will be discussed in another post after this one.

The key point to remember is that starting at meal 3, or around lunch-time, make the majority of your carbs vegetables or fibrous carbs.

How to Eat a Lot and Lose Weight

Did you know that you can eat a lot and still lose weight? It sounds too good to be true, right? Here are some ways to make it happen.

1.Eat a lot of healthy, low-fat foods rather than junk food. Adding a lot of vegetables and fruits to your diet will help you. Drink bouillon made with filtered water to help you feel full.

2.Go ahead and have that donut or slice of pizza, but before you do, drink a few glasses of water and eat a bowl of raw veggies such as cucumbers, celery, carrots, and tomatoes. They will fill you up and you will have very little room to eat the "junk" food.

3.There are two things you eat and drink that contain no calories: water and fiber. The more of these you get into your diet, the better off you will be. For example, you can eat a pound of mixed salad greens with assorted raw vegetables (carrots, red cabbage, celery, broccoli, onion, etc.) with a low or no-calorie salad dressing and only have eaten 100-150 calories. This is because of the high water and fiber content of the salad and low calorie dressing.

4.Always use utensils and sit at the table. This stops you from descending into "binge hell" where you have your head in the fridge eating with your hands.

5.Eat slowly and stop when you're full. If you can't stop then say "OK, I can't stop so that means I can't______." Fill in the blank with something you like to do other than eating. Maybe you can't put on make up, use the computer or go to town.

6.Exercise every day! Get your heart rate up and start out at 10 minutes then work your way up by adding 5 or 10 minutes each day.

7.Craving chocolate usually means you need more magnesium. Take the RDA of magnesium a day beyond what you would get from your food.

8.If you eat 100-150 calories or so every two hours, your body stays in a high-metabolism digesting mode. This allows you to burn more calories than eating just 3 meals a day.

Tips
Avoid calorie dense, unhealthy food. Unhealthy food is food which contains calories, but little nutritional value. These calories are called "empty calories." You will probably be best served if you also avoid foods that would contain empty calories if they were not fortified with vitamin C (like some gummy bears) or calcium (like some cookies). Fortification with vitamins doesn't always make unhealthy food healthy.

Try to do a little bit at a time until you get used to it.

Get a friend to follow a healthy living diet with you. Sometimes, when following a diet by yourself, you'll break the rules because it's just you. But following it with a friend, you have a partner who will help keep you on track and responsible.

Expect to cheat or binge once in a while. (A word of caution: if you're binging more than once or twice a month, consider a different approach to your weight loss goals.) Don't despair when you realize you've strayed from your goals. It took you many years to achieve your current weight, and it will take time to achieve your new weight and size goal.

Remember:
You have to exercise and eat healthier, otherwise you will not notice any improvement and—even worse—you will gain weight.

4-6 Smaller Meals

Why eating 4-6 smaller meals more frequently is better than 3 large meals



Now that you understand the importance of creating a caloric deficit each day and listening to your body to serve as your guide of when and how much to eat, let's look at another effective strategy to ensure your success:small, frequent meals – around 4 - 6 meals/day, about 2½ - 3 hours apart.

Eating a large meal increases the opportunity for fat cells to extract fat from the blood and, therefore, grow bigger. Fat cells can actually adapt to a pattern of large, infrequent meals by becoming more efficient at storing fat. In addition, a 2-3 meal-a-day pattern causes the body to face long stretches without food. By the time lunch or dinner rolls around, you’re so famished you’re more likely to make unwise food choices and overeat.

Eating smaller meals more frequently throughout the days not only prevents you from gorging on unwise food choices; it helps you feel energized and satisfied throughout the day.

In addition to eating smaller meals more frequently, try to plan so that you don't eat your largest meal late at night. The body's metabolic rate has a natural cycle of highs and lows, peaking late in the day and dropping to its lowest level during sleep. So, it makes sense to avoid putting a large meal into your system 2 to 3 hours before bedtime, when your metabolic rate is beginning to slow down. If you do feel hungry after this time, you don't need to go to bed hungry; just eat something especially low in calories and in a small portion.

It is important to note, just because you eat at night, it doesn’t necessarily mean you’ll gain fat. If you’re still in a caloric deficit, whether you eat at night or not, you’ll still likely lose fat. But eating less at night is an easy way to keep calories under control, especially since these extra calories aren’t needed at night before you go to bed because you’ll be inactive while you’re sleeping.

Key points to remember:

1. Eat small, frequent meals (4 - 6 meals/day) about 2½ - 3 hours apart, and try to eat fewer calories later in the day.

Daily Activity

How being more active throughout the day helps you lose fat


Now, just as it’s important to consume fewer calories, it’s also important that you’re active throughout the day to expend more calories.

You can help create a caloric deficit not only by eating small portions of the right types of foods, but also by being more active throughout the day. If the goal is to expend more calories than you consume, then it only makes sense that you’d want to be more active to make sure you create a caloric deficit.

Take every opportunity to be as active as possible throughout the day. The more active you are, the more calories you'll burn, and the easier it'll be to create a caloric deficit for maximum fat loss.

Exercise doesn't have to be limited to the track or the gym. You can greatly increase the amount of physical activity your body gets (and the total calories you burn) by making small lifestyle changes to be as active as possible throughout the day..



Here's a few simple examples:

  • Get in the habit of taking the stairs instead of the elevator.
  • Keep your sport shoes in the car so you're always prepared to get out and be active when you have some extra time. You could take a brisk walk or shoot some baskets after lunch before returning to work.
  • Choose a hike or a bike ride instead of a movie.
  • Play with your kids in the backyard rather than dropping them off at the video arcade.
  • Instead of catching up with friends over a few drinks, play racquetball or tennis.

Any extra bit of activity adds up and over the long-run and makes a big difference in how much fat you lose.

Key points to remember:

1. Take advantage of every opportunity to be more active throughout the day to help create the caloric deficit.

Exercises at Home

Here are some resistance training exercises that you can do using just your own body weight:
  1. Pushups- standard, on knees, feet propped up on a chair, leaning on a wall, upper body propped up on a couch, etc. There are even more variations by changing body placement and hand-width.
  2. Crunches- feet on floor, lets bent in air, legs straight in air, bicycle crunch, full sit-ups, oblique crunches, plank.
  3. Lunges- walking lunges, stationary lunges, side lunges, reverse or front lunges.
  4. Squats- feet together, feet shoulder-width, feet wide, back on wall (holding wall sit), holding extra weight (dumbbells, full Buccee's jug, baby), one-legged squats (advanced!)
  5. Bridges- lie on your back, legs bent, feet on floor. Lift hips toward ceiling, squeezing glutes the whole time. Challenge yourself by keeping one leg up in the air.
  6. Cardio- climbing your stairs, running/walking/jogging outside, hiking, jumping rope (or just jumping period), kickboxing routines, fitness videos, biking, etc.

Fat Facts


Fat Facts

Dietary fat is found in both animal and plant foods. There are three basic classifications of fat: (1) monounsaturated, (2) polyunsaturated and (3) saturated. Unsaturated fats--especially monounsaturated fats--are considered the "h
ealthier" ones. Sources of unsaturated fats include nuts, seeds, vegetable oils and soft margarine products.

Research indicates that an excessive intake of saturated fats tends to raise blood cholesterol levels, thereby increasing risk for heart disease. Animal products--such as beef, butter, dairy products and lard--typically contain more saturated fat than do vegetable products. But some vegetable oils, such as coconut and palm oil (also known as tropical oils), contain large amounts of saturated fat.

There's also an unclassified newcomer in the fat realm--trans fatty acid. Trans fatty acids are the end products of a process called hydrogenation, in which vegetable oils are hardened. The implications that trans fatty acids may play a negative role on health is currently being reviewed, but many nutrition professionals are already advising a limited intake.

The Bottom Line

Health authorities recommend that Americans consume 30 percent or less of their total daily calories from fat, with 10 percent or less of those calories from saturated fat. Use the Nutrition Facts panel on food labels to help determine how much fat is in food. The following chart can help guide your fat intake. Determine how many calories are in your diet and use the chart to discover how many grams of fat are in 30 percent and 10 percent of your calorie intake. Remember, the recommended percentages refer to your total fat intake over time, not the fat in single foods or meals.

Calories per Day--Total Fat per Day (grams)- -Total Saturated Fat per Day (grams)
1,200-- 40 or less- -13 or less
1,600-- 53 or less- -18 or less
2,000-- 67 or less- -22 or less
2,200-- 73 or less- -24 or less
2,500-- 83 or less- -27 or less

10 Tips to Reduce Fat

To help cut down on your fat intake, use the following tips when preparing foods:

1. Use evaporated skim milk instead of cream when preparing sauces or desserts.

2. Create your own nonfat salad dressing by mixing balsamic vinegar, mustard and herbs. If you really prefer an oil-based dressing, try using three parts vinegar to one part oil.

3. Drain nonfat yogurt through a sieve or cheesecloth overnight in the refrigerator, and use in recipes that call for cream.

4. Sauté foods in chicken broth, vegetable stock, tomato juice or wine instead of frying them in oil or butter.

5. Keep olive oil in a spray bottle to a lightly coat sauté pans.

6. You can make your own taco shells. Hang soft corn tortillas directly over the oven rack (with the sides of the tortilla hanging down) and bake at 400 degrees until they're crisp. (Taco shells sold in supermarkets are usually fried.)

7. Whip up your own french fries. Place 1/2-inch-thick potato slices on a nonstick baking pan and coat with a light spray of oil. Sprinkle with paprika or salt, and bake at 350 degrees for 35 to 40 minutes. Turn once during baking. (For a different flavor, try this recipe with sweet potatoes.)

8. To maximize flavor, toast nuts before baking with them. That way, you'll be able to use less. Or sprinkle nuts on top of a home-baked dessert instead of mixing them into the batter.

9. Substitute six egg whites plus one whole egg for every three eggs in your favorite recipes.

10. Substitute an equal amount of applesauce or any baby-food fruits for up to half of the total oil in your favorite dessert recipes. Strained prunes actually enhance the chocolate flavor in brownies!

Interval Training

Ok, so most of us have a goal of getting lean and losing fat, right? Well, we're doing that in bootcamp by using efficient exercises--full-body exercises that allow you to train several muscle groups at once. Obviously the more muscles used per exercise the better. By doing pushups, for example, we can train our chest, shoulders, and abs all at once. Lifting moderately heavy weights for a lower number of repetitions will help gain muscle (not bulk you up) at the same time as you lose body fat, and it will also help you burn a lot more calories during your workout and after. To lose fat, you have to choose the right total body exercises, exercise at the right intensity and perform shorter bouts of metabolism-boosting interval training to get results. If you do this, you'll not only reach your goals faster, but you'll cut down on your workout time. Click on the "Interval Training" and "More Interval Training" links under "Additional Resources" on the right column to learn more, and contact me with any questions. These are great things to do on your non-bootcamp days or over the weekend for your cardio. Also, below is a link with some more information regarding interval training.

Diets Don't Work!


Many Americans view a healthy lifestyle as something difficult to attain--and something that's not much fun. Traditional diets have taught us that to lose weight, we must count calories, keep track of everything we eat, and deprive ourselves by limiting the amount--and kinds--of foods we eat. Diets tell us exactly what and how much food to eat, regardless of our preferences and individual relationships with hunger and satiety. Dieting can help us lose weight (fat, muscle, and water) in the short term but is so unnatural and so unrealistic that it can never become a lifestyle that we can live with, let alone enjoy!

While very few diets teach healthy low-fat shopping, cooking, and dining-out strategies, many offer unrealistic recommendations and encourage health-threatening restrictions. Even more important, diets don't teach us the safest, most effective ways to exercise; they don't teach us how to deal with our cravings and our desires, or how to attend to our feelings of hunger and fullness. Eventually, we become tired of the complexity, the hunger, the lack of flavor, the lack of flexibility, the lack of energy, and the feeling of deprivation. We quit our diets and gain back the weight we've lost; sometimes we gain even more!

Each time we go on another diet of deprivation, the weight becomes more difficult to lose, and we become even more frustrated and discouraged. Then we eat more and exercise less, causing ourselves more frustration, discouragement, depression. Soon we are in a vicious cycle. We begin to ask ourselves, "Why bother?" We begin to blame ourselves for having no will power when what we really need is clear, scientifically-based information that will help us develop a healthier lifestyle we can live with for the rest of our lives.

Deliberate restriction of food intake in order to lose weight or to prevent weight gain, known as dieting, is the path that millions of people all over the world are taking in order to reach a desired body weight or appearance. Preoccupation with body shape, size, and weight creates an unhealthy lifestyle of emotional and physical deprivation. Diets take control away from us.

Many of us who diet get caught in a "yo-yo" cycle that begins with low self-acceptance and results in structured eating and living because we lack trust in our body and are unwilling to listen and adhere to our body's signals of hunger and fullness. On diets, we distrust and ignore internal signs of appetite, hunger, and our need to be physically and psychologically satisfied. Instead, we depend on diet plans, measured portions, and a prescribed frequency for eating.

As a result, many of us have lost the ability to eat in response to our physical needs; we experience feelings of deprivation, then binge, and finally terminate our "health" program. This in turn leads to guilt, defeat, weight gain, low self-esteem, and then we're back to the beginning of the yo-yo diet cycle. Rather than making us feel better about ourselves, diets set us up for failure and erode our self-esteem.

The attitudes and practices acquired through years of dieting are likely to result in a body weight and size obsession, low self-esteem, poor nutrition and excessive or inadequate exercise. Weight loss from following a rigid diet is usually temporary. Most diets are too drastic to maintain; they are unrealistic and unpleasant; they are physically and emotionally stressful. And most of us just resume our old eating and activity patterns. Diets control us; we are not in control. People who try to live by diet lists and rules learn little or nothing about proper nutrition and how to enjoy their meals, physical activity, and a healthy lifestyle. No one can realistically live in the diet mode for the rest of their life, depriving themselves of the true pleasures of healthy eating and activity.

We Don't Fail Diets; They Fail Us!

Decades of research have shown that diets, both self-initiated and professionally-led, are ineffective at producing long-term health and weight loss (or weight control). When your diet fails to keep the weight off, you may say to yourself, "If only I didn't love food so much . . . If I could just exercise more often . . . If I just had more will power." The problem is not personal weakness or lack of will power. Only 5 percent of people who go on diets are successful. Please understand that we are not failing diets; diets are failing us.

The reason 95 percent of all traditional diets fail is simple. When you go on a low-calorie diet, your body thinks you are starving; it actually becomes more efficient at storing fat by slowing down your metabolism. When you stop this unrealistic eating plan, your metabolism is still slow and inefficient that you gain the weight back even faster, even though you may still be eating less than you were before you went on the diet.

In addition, low-calorie diets cause you to lose both muscle and fat in equal amounts. However, when you eventually gain back the weight, it is all fat and not muscle, causing your metabolism to slow down even more. Now you have extra weight, a less healthy body composition, and a less attractive physique.

Diets require you to sacrifice by being hungry; they don't allow you to enjoy the foods you love. This does not teach you habits which you can maintain after the diet is over. Most diet programs force you to lower your caloric intake to dangerously low levels. The common theory is that if you eat fewer calories than you burn, you will lose weight. But when you eat fewer calories than your body needs to maintain its life-sustaining activities, you're actually losing muscle in addition to fat. Your body breaks down its own muscles to provide the needed energy for survival.

Traditional diets which use calorie restriction to produce weight loss are no longer appropriate. Most weight-loss programs measure success solely in terms of the number of pounds lost per weight loss attempt. Diets don't take into account the quality of the process used to achieve that weight loss or the very small likelihood of sustained weight loss. For long-term good health, you need to move away from low-calorie diets and focus on enjoyable physical activity and good nutrition. Exercising regularly and eating lean-supporting calories, protein and carbohydrates, and reducing fat-supporting calories will not only help you look and feel better, it will also significantly reduce your risk of disease.

America spends billions of dollars on different ways to fix people. If we focused more on prevention and on improving our day-to-day behaviors, we could cut health care costs in half. Contrary to popular belief, leading a healthy lifestyle doesn't have to be difficult; it doesn't have to be painful or time-consuming. Making gradual, simple changes in your diet and physical activity will make great improvements in your health and well-being, and they can drastically reduce your risk of disease.

If your weight management program is to be a success, everything you eat and every exercise you do must be a pleasurable experience. If you're not enjoying yourself, it is unlikely that you'll continue your program. It's that simple. These small, gradual changes are not painful or overwhelming but rather the core of an exciting lifestyle that you will look forward to.

Take the frustration, guilt, and deprivation out of weight management, and allow yourself to adopt gradual, realistic changes into your life that will make healthy eating and physical activity a permanent pleasure. You will soon discover what your body is capable of and begin to look, act, and feel your very best. Good luck and enjoy all the wonderful benefits of a healthy, active lifestyle.
