Do You Have to Exercise and Work Out to Lose Weight? The answer is YES & NO:
NO you don't have to work out and exercise like fanatic or athlete, YES you need to move around. More often than not, you will hear that weight loss plans that do not include exercise are not serious. This is accentuated by the fact that some of the weight loss scams deliberately advertise that you can lose weight without exercising. The difficulty with most traditional weight loss programs is that they often have confusing goals. They want you to change all of your foods and at the same time ask for your regular physical exercise, sometimes as much as 2 or 3 hours a week in a gym. Overwhelming you with a complicated, time-consuming exercise plan while eliminating and adding all kinds of new food at the same time will more then likely lead to failure in achieving both goals. The typical result is a few weeks of diet and work out stress and a few pounds of weight loss. You will miss the gym a few times, for whatever reason and that ends the whole plan. It's often and "all or nothing" attempt that turns into nothing.
Many researchers believe that sedentary, overweight individuals can be successful with their weight loss plans with a simple and slight increase in the amount of physical activity in their daily lives. Call this life “lifestyle exercises” or as Dr James Levine from the Mayo Clinic, NEAT. In the figure below you see that even daily movement not even approaching the
Benefits of Lifestyle Exercises:
Strengthens your cardiovascular system
The term “cardiovascular system” refers to the heart and blood vessels. Cholesterol buildup in the arteries can cause strokes and heart attacks. Regular physical activities prevent this from happening in three different ways:
· Lower the buildup of bad cholesterol (LDL) in arteries by increasing the concentration of good cholesterol (HDL) · Prevent the onset of high blood pressure if one is at increased risk of developing this condition · Lower your blood pressure if already high
Keeps bones and muscles strong
Regular physical activities are one of the best methods to prevent osteoporosis and strengthen muscles. Choose lifestyle exercises that bear your body’s weight, such as walking and jogging.
Can help to break through plateaus
Physical activities will help to increase metabolism again after the normal slowing that accompanies weight loss. In this case, I do recommend working a little harder while doing your lifestyle exercises. Walk a little faster and maybe a little longer to break a sweat. And maybe add one or two more physical activities a day during those periods.
Prevents and manages diabetes
Regular physical activities, coupled with weight loss, are important ways to control blood sugar. Exercise helps insulin work and can lower blood sugar.
Eases depression and manages pain and stress
Regular physical activities can help fight depression by activating the neurotransmitters (chemicals used by your nerve cells to communicate with one another) serotonin and norepinephrine. Exercise also stimulates the production of endorphins, other neurotransmitters that produce feelings of well being.
Reduces your risk of certain types of cancer
Regular physical activities may help lower the risk of cancers of the colon, prostate, uterus, and breasts.
Helps you sleep well
A good night’s sleep helps maintain your physical and mental health. Moderate physical activities at least three hours before bedtime can help one relax and sleep better at night.
In addition to making you feel better, regular physical activities definitely prolong life expectancy.
1. If you are not exercising, consider “lifestyle” exercises. The are equally or more effective than structured aerobic or weight lifting exercise for weight loss.
2. Look at the calories you are doing with any activity. Get a pedometer, look at the calories meters, measure off a mile with you car if you are walking outside. Having an idea about the calories you really burn during exercises permits one to understand the effort it takes to burn off the calories of bad food choices.
3. Exercise plays only a minimal role in short-term weight loss; the obsession with hours of working out in gyms often diverts attention from what is really important—the foods that that one eats.
4. Diet and/or exercise cannot remove genetically determined fat deposits in most individuals. (Both figures from Dr James Levine, "Nonexercise activity thermogenesis (NEAT): environment and biology"
