Question:
My son (age 20) has Type 1 Diabetes. He was diagnosed at the age of 9. His
problem is as follows: He works out at the gym 3 times a week and lifts
weights. He also rides a stationary bike 10 miles during his workout. He
watches his fat intake and has good control over his diabetes. But he wants
to lose what he calls his love handles around his mid section. His body is
very muscular, legs arms chest. However his stomach needs work. He also works
out with a Tony Little Abdominal Machine that is similar to sit-ups without
the strain on his lower back. Nothing seems to work. It is really bothering
him and I thought maybe your team would have an idea for perhaps a diet
change, or a particular exercise he could try.
Answer:
I do not know your son's height, weight, body composition, the amount of time
or the intensity at which he does his bike riding at the gym or what his
daily diet consists of. All of the above are things to consider when looking
at the entire picture. I really think it is great that your son is taking
time to workout at the gym
3 times a week; engaging in a 10 mile bike ride, lifting weights as well as
watching his fat intake. I trust that he is in good control of his diabetes
without any complications that may affect his exercise routine (i.e.,
retinopathy or high blood pressure) and that he does check his blood glucose
before and after each exercise session.
With regard to what he calls his "love handles," it seems as if you are
actually asking for information about spot reducing. The Myth of Spot
Reducing: What is it? Many individuals exercise to improve their body
appearance. Spot reducing involves localized exercise in the belief that it
reduces fat stores in the active areas. The underlying basis for this belief
is that by exercising a specific body area, more fat will be selectively
reduced from that area than if exercise of the same caloric intensity was
performed by a different muscle group. So an advocate of spot reducing would
encourage or recommend engaging in countless numbers of sit ups or using an
abdominal machine to get rid of that mid section. It is believed that an
increase in a muscle's activity facilitates or aids in a relatively greater
fat mobilization from the specific storage areas.
Current knowledge of energy supply indicates that exercise stimulates the
mobilization of fatty acids through hormones delivered through the blood to
act on the fat depots throughout the body. The areas of greatest fat
concentration probably supply the greatest amount of the energy. The is
simply no evidence the fatty acids are released to a greater degree from the
fat pads directly over the exercising muscle.
Where the promise of spot reducing with exercise is extremely attractive to
many of us from the aesthetic point of view, let's take a look at what
research supports. The most convincing evidence against the spot reducing
concept is that of high caliber tennis players. Comparisons were made of the
circumferences and subcutaneous fat stores of their right and left forearms.
The circumference of the dominant or playing arm was significantly larger
than the non dominant arm. This was the result of a moderate muscular
hypertrophy associated with the muscular overload provided by tennis. In
essence, the dominant arm's muscles were worked more, therefore they became
larger. However, measurements of fat fold thickness showed that there was no
difference between arms in the quantity of subcutaneous forearm fat. Clearly
prolonged exercise of the playing arm was not accompanied by reduced fat
deposits specifically in that forearm.
The well know fact remains: exercise cannot rid the body of fat in specific
places. Muscle tone can be improved in some areas of the body and thus may
help to improve appearance somewhat. So keep up with the sit ups. In choosing
an activity, however, the focus should be on caloric expenditure as well as
enjoyment (to promote compliance) rather than spot reducing.
Finally, here is a reference you may like to read with
regard to the piece of research I cited. I hope I have been of some help to
you:
