I found a great article today, written by Sue Montague, and I am reprinting it here: it’s food for thought….
“I do aerobics 3 times a week and I just don’t seem to lose weight” Does this sound familiar?
Losing weight is based on a very simple principle……. energy balance.
If you burn up more energy than you take into your body in the form of food etc., you will be in a negative energy balance and your body will burn up your own store of energy to make up the deficit, with the result being……..you will lose weight. It all sounds too easy doesn’t it but there are other factors at play.
It’s common for those who decide that they need to lose weight to think that the answer is to do more exercise… walking, running or other cardio type exercises.
This does work in a few cases but research has shown that this type of exercise alone is not enough to lose weight.
A study completed at Appalachian State University shows that aerobic exercise has little effect on body composition over a 12-week period.
The research team assigned a group of 91 over weight women to one of four groups. Group 1 followed a restricted calorie diet (1,200 – 1,300 calories per day) Group 2 performed aerobic exercise for 45 minutes five days per week Group 3 combined exercise and diet Group 4 acted as controls.
The exercise-only group (Group 2) lost just three pounds. This is despite the fact they were exercising for almost four hours each week. Not surprisingly, the women combining diet and exercise (Group 3) got the best results, losing 16 pounds (7 kilos) of fat. However, this was only one pound more than the group on the calorie restricted diet (Group 1). These disappointing results led the researchers to conclude that aerobic exercise has only a “minor, nonsignificant effect” on fat loss. So why is that?
Lets look at the facts on aerobic exercise.
It is true that you will burn some calories with this type of exercise, but only a small amount. For example if you jog for 30 minutes you will only burn up around 200-300 calories which is the equivalent of one large apple and a banana. A hamburger would be around 500-600 calories and that’s without the fries so you would need to exercise for a lot longer..
It’s not that aerobic exercise is no good for you, on the contrary, there are many scientific studies that have shown that aerobic exercise helps to reduce the risk of heart disease, the onset of diabetes and helps prevent many other health problems….but aerobics alone is not very effective for weight loss. Reason being the relatively small amount of calories you burn up for the time you spend exercising. There is also a potential for loss of muscle mass with heavy aerobic exercise especially when coupled with a calorie reducing diet.
If you are participating in a heavy aerobic program your body will need to burn more carbohydrates than fat and unless you are consuming extra carbohydrates your body will manufacture them from protein. It obtains this protein from your muscles, this process is called catabolism and results in the loss of muscle mass. Add to this the fact that you are also reducing your intake of carbohydrates and protein and you have a recipe for failure.
How does this affect long term weight loss?
It will seem that you are losing weight judging from your bathroom scales but this actually is sabotaging your long term permanent weight loss. When you lose muscle, you lose the ability to burn calories. With less muscle we burn less calories resulting in a lower metabolism.. Metabolism is the process of turning stored calories into energy. The higher the percentage of muscle to fat in your body, the faster your metabolism.
If you are a so called ‘yoyo’ dieter your fat to muscle ratio is high. Therefore you have a low metabolism and gain weight very easily. You need to maintain or increase your lean muscle tissue which helps in increasing your metabolism.
So what’s the answer to Permanent Weight Loss?
The answer to a permanent weight loss solution is a combination or all three elements.
1. Light aerobic exercise for health and some calorie burning.
2. Eat a balanced diet with some reduction in calories and increase in your protein intake.
3. Weight training, resistance or strength training.
Resistance or Weight Training
The most important of these three is weight training. You need to increase your lean muscle mass to help speed up your metabolism and if you are already reducing your calorie intake you will burn fat even quicker and get better and more permanent results. I do suggest using some form of Nutritional Supplementation to ensure that you are getting everything your body needs to remain healthy whilst losing weight.
