How can we burn a maximum amount of calories in a minimum amount of time? 

A comment from a reader who writes, “You should check the latest research on fat burning. You suggest that long slow distance (LSD) is the way to go for newbies. But that’s not what the new information says.” Well, the reader is correct, but….. read on. 

 Why Not Skip LSD Training and Get Right to the Best Calorie Burns?
 

If you are new to fitness, or have not been doing cardiovascular exercises such as walking, swimming, jogging, elliptical training, biking etc., then the suggested long slow distance training with minimal emphasis on heart rate intensity is used to build a base of endurance for furthering harder intensity calorie burning zones. Think of this slow long training as a necessary “evil” for furthering fat burning ability. A long slow distance base of training aids in the formation of new life changing habits, primes the muscles, ligaments, and tendons, as well as the cardiovascular system for a lifetime of increased fat burning ability and a speedier anti aging higher metabolism by reducing the occurrence of injuries, as well as the occurrence of premature overzealous training which often leads to failure. 

Fat Burning Zone Explained in Brief 

In order for a muscle to function it needs energy. There are three options that a muscle has to use fuel: 

1 Carbohydrates
2. Fat
3. Protein- only used by muscles under depleted circumstances. Consider carbohydrates and fats as the two main sources. 

When using energy our muscles use a mix of carbohydrates and fats, this is based on a number of factors, one of them being intensity and duration of activity. Fats require more oxygen than carbohydrates to burn. As a result, as exercise intensity increases and less oxygen is available, the body shifts from a fat burning zone to using carbohydrates for energy in order to maintain the activity. This doesn’t however mean that less fat is burned. In low intensity exercise the fat being used is coming from the blood stream and this was traditionally called the fat burning zone. In order to understand the whole picture though, we must look at where the source of the fat being used is coming from. 

Energy Source Paramount in Increasing Fat Burn Ability 

With increased intensity and duration of an activity, the muscles need more oxygen and energy, so our hearts beat faster to get blood to the muscles quicker. In medium intensity long duration activities the blood stream gets overloaded with work, including the job of providing an energy source to the working muscles. When looking to increase our fat metabolism, it’s necessary to get to this point of overloading our bloodstream’s energy sources. By doing this, the overloaded blood stream must turn to its own body’s muscle fat – namely the primary muscle mover’s fat (triglycerides) and glycogen (sugar) stores- which provide energy to the working body. Obtaining a state of moderate intensity training, where the body is working harder and the heart rate is being taxed at a perceived exertion of 6 out of a 10 point scale is when fat burning is amplified beyond just a simple calorie burn. To translate this into a target heart rate, achieve a heart rate of approximately 80% of your maximum heart rate and continue for duration of 20 minutes and preferably 30 – 60 minutes continuously.
  

How to Figure Target Heart Rate at 80 Percent 

-Take 220 minus your age.
-Multiply this number by .80.
-Your number is your THR for an increased and more efficient fat burning zone 

Fat burning can be optimized further with high intensity interval training. It’s what all the fitness magazines are writing about.  The secret lies in what is called the after-burn. It breaks all the rules applied here, but you’ll see why it’s absolutely necessary in obtaining a lean more muscular look that includes the difficult to diminish waistline. You can do it! Stay tuned and I’ll help you out.

I am frequently asked by my patients, “What is the best weight loss diet?” (Followed by the question, “What pill can you give me to lose weight?” which is the topic of another article!) My answer is, “Whatever diet works for you.” THERE IS NO SUCH THING AS “THE DIET.” Many diets promote weight loss and improve overall health.

For example, the Ornish diet is the traditional low fat/high vegetable diet. The Mediterranean diet includes significant intake of fish, occasional red wine in some cases, olive oil and mixed nuts. The DASH diet, Dietary Approaches to Stop Hypertension, includes whole grains, some meats and no more than 2/3 tsp salt daily. The DASH diet helps prevent hypertension. Patients who follow high protein, low carbohydrate Atkins or Zone diets also successfully lose weight. Similar to the low carbohydrate diets are the low glycemic diets, such as the South Beach diet, which emphasize carbohydrates that avoid rapid increases in blood glucose after being eaten.  The Pritkin diet is a VERY low fat diet.

Food and supplement replacement diets (Nutrisystem, Optifast, Slimfast) also work, as do group programs such as Weight Watchers that emphasize support systems and group weigh-ins. Confused yet?

The problem with every diet system is that the weight is regained unless the dietary changes become a permanent part of one’s eating routine. So if you can’t eat high protein and fat, or low fat and vegetables, or protein shakes for the rest of your life, you will regain the weight.

What I suggest is small changes that can be a permanent part of your life. Remember, obesity is a lifelong condition, just like allergies or arthritis. If you stop treatment, weight gain, just like other chronic illnesses, will recur.

Here are some strategies to start before going on a radical diet. They are healthy first steps to improving your overall health. I challenge you to do (consistently) just ONE of the following strategies as the first step toward weight loss, health and fitness:

1) Eat a small, healthy protein/fruit rich breakfast.

2) Skip second helpings.

3) Decrease portion size of meats (3 oz, the size of a deck of cards)

4) Increase your activity. Start with five minutes of leisurely walking three times a week to simply incorporate exercise into your weekly routine. If you actually make the initial effort to set aside a small amount of time for exercise several days a week, you will slowly notice that you naturally increase your exercise exertion and endurance without significant effort. Of course, it is ESSENTIAL that you consult with your primary care physician first before starting any exercise program.

5) Stop telling yourself (and your doctor) that your stressful life/job/family responsibilities/joint limitations prevent you from finding time to exercise. The president of the United States exercises. Neurosurgeons and Fortune 500 company CEOs and carpool Moms exercise. Is your life more demanding than theirs? You can’t find five minutes three days a week to go window shopping? (Remember window shopping is the START, not the ultimate GOAL of your exercise program!)

6) Skip second helpings (worth mentioning again).

7) Consider eating six small meals a day instead of three large meals, and make dinner your smallest meal.

 8) Add more fiber, naturally, through whole grains (unless you have celiac disease), or fiber supplements. This is important for better colon health and to help serum cholesterol.

9) Cut out sodas and other sugary drinks.

10) Cut out alcohol.

11) Make a DETAILED food diary.

12) Decrease or eliminate sweets (Don’t buy them for your home, especially if you have children—you want them to develop healthy eating habits at a young age).

13) Cut out fast foods.

14) Walk across the parking lot to your job or up the stairs—this is the starting point, not the ultimate goal, of your exercise program.

15) Incorporate calcium sources into your diet

16) No food from vending machines!

17) No snacks after 7 PM.

18) Think about loving your body with all it’s imperfections. Concentrate on improving your health and well being rather than looking like a movie star.

19) Decrease TV time (and hence “snack time”)

20) Everyone in the family eat together for as many meals as possible, especially dinner. You and your teenagers are more likely to eat healthy meals, rather than fast food, this way.

21) Try to eat at least five fruit and vegetable servings a day.

Even if you don’t follow a “name” diet perfectly, incorporating ONE or more of the above measures is a great starting point, and will give you a sense of mastery and accomplishment. I ask patients to accomplish that FIRST SMALL step in their lifelong odyssey toward a healthy weight, decreased susceptibility to illness and most importantly, feeling energetic and happy!
