Fact or Fiction?
Age 40 = A Slow Down in Metabolism = Potential Weight Gain
Fact: But you can make it FICTION
Iit’s true that our metabolism naturally slows down after the age of 40, but it only slows by about 2% – 5% per decade, and there are plenty of things we can do to fight back and speed it up.
What is Metabolism? Metabolism is the amount of energy (calories) your body burns to maintain itself. Whether you are eating, drinking, sleeping, cleaning etc… Your body is constantly burning calories to keep you going.
Metabolism is affected by your body composition. Body composition, meaning the amount of muscle you have versus the amount of fat. Muscle uses more calories to maintain itself than fat. People who are more muscular (and have a lower percentage of body fat) are said to have a higher metabolism than people who are less muscular.
Exercise is key to taking charge of your metabolism, especially at 40.
Aerobic exercise 4 to 5 days a week: Aerobic activities like running, brisk walking, swimming and bike riding burn calories and increase metabolism while you’re working out. Aerobic activities also cause your metabolism to stay increased for a period of time after exercising. Keep in mind, that this afterburn is usually fairly insignificant compared to the amount of calories you burn in total… but every little bit helps.
Work your muscles: Lifting weights and/or other strengthening activities on a regular basis (at least 2-3 times each week) will boost your resting metabolism 24/7. That’s because these activities build muscle, and muscle burns more calories than body fat; if you have more muscle, you burn more calories — even sitting still.
Diet is also key to taking charge of your metabolism.
Because our bodies work hard to digest and absorb the foods we eat, our metabolism gets a boost when we eat. This is called the thermic effect of food. Eating all foods creates a thermic effect and will boost metabolism after consumption. Protein has the greatest metabolic boost when compared to carbohydrate and fat. This means that your body burns more calories to digest protein than it does to burn carbs and fat. (That is one reason that high protein diets were a popular trend)
By eating smarter, keep your metabolism going strong with these tips:
Eat enough food: Your body and metabolism thrive on food; your metabolism revs when it gets food. It is important to note that when you fast, crash-diet or restrict calories below 1000, your metabolism will SLOW down in a response to conserve energy, so know your daily calorie requirements to maintain your weight, and then you can adjust it accordingly if you want to lose weight.
Calorie requirements for weight maintenance
For sedentary people: Weight x 14 = estimated cal/day
For moderately active people: Weight x 17 = estimated cal/day
For active people: Weight x 20 = estimated cal/day
Note: Moderately Active is defined as 3-4 aerobic sessions per week. Active is defined as 5-7 aerobic sessions per week.
Eat every 4-5 hours: This means that you are boosting your metabolism, revving it up throughout the day. You must choose your foods and snacks wisely, though.
Incorporate lean protein with every meal: As I mentioned before, protein has the greatest metabolism boost after consumption, PLUS, eating the appropriate amount of protein helps to maintain and build muscle mass (the more muscle mass you have, the greater your metabolism).
Daily Protein Requirements: At least 50% of your weight = daily grams of protein
Some of the best protein sources include: fish, chicken, turkey, lean sirloin steak, skim milk, yogurt, eggs and egg substitutes, tofu.
So, if you are 40 something, speed up that metabolism! You will be glad you did… especially when you hit 50!
Vigorous Activity (Zone 7)
24 08 2009How vigorous should your workouts be for the most effective weight loss?
You may have heard that exercising at a slower pace is more effective for fat loss than working out more intensely. In fact, many cardio machines have “fat burning” programs that keep you at a slower pace. But this is very misleading.
During low-intensity aerobic exercise, your body does use fat as its primary fuel source. However, and this is key, picking up the pace allows you to burn more total calories, as well as more fat calories. The most important factor in exercise and weight control is not the percentage of fat calories burned, but the total calories burned during the activity. The faster you walk, bike or swim, for example, the more calories you use per minute, and you will be burning more total calories, and in turn, will lose more weight.
Here’s how: If you go walking for 30 minutes at a leisurely roll, you might burn about 100 calories — about 80 percent of them from fat (so that’s 80 fat calories). But if you spend the same amount of time running, you might burn 300 calories — 30 percent of them from fat (that’s 90 fat calories). So at the fast pace, you burn more than double the calories and 10 more fat calories. Which is better for weight loss? Burning 100 calories or 300 calories (in the same amount of time).
Keep in mind; if can’t sustain a faster pace long enough to make it worth your while., a slower pace will allow you to exercise longer, so you’ll end up burning more calories and fat that way. So you need to find a good balance, and change it as you gain more endurance. As your endurance increases, your intensity must increase. For the best weight loss results, you should try to complete at least 15 minutes of your cardio exercise at the most vigorous pace you can. 30 minutes is even better.
There are all sorts of formulas for figuring out your target heart rate and then using that number to calculate your desired intensity. This is another area where my eyes start to glaze over a bit…. One of my favorite websites for advanced training makes this question easy for you to answer on an individual basis without having to figure out all those numbers and continually take your heart rate. Askthetrainer.com has a great chart . (See below)
As you can see, this “formula” is based on how you feel, not a bunch of numbers. Don’t get me wrong, finding out your target heart rate is very beneficial, but for me, this is a better guide and easier to utilize on a consistent basis, especially as I gain more endurance, and strength. It also takes into account how I am feeling on low energy days and high energy days (see exercise tip of the week for more information on that). The zone for the most effective weight loss is zone 7. Vigorous Activity.
