to create fuel. Correspondingly, fast-twitch
muscle fibers are much better at generating
more immediate muscular response needed
to sustain short bursts of strength and speed
that resistance-training individuals are en-
gaged in. Uni quely, surmised here, tomatidine
has conclusively shown the ability to increase
strength and workload capacity. Despite this
attribute, fast-twitch muscle fibers fatigue at
a faster rate. Conversely, slow-twitch muscles
use aerobic metabolism (with oxygen) to
create fuel. They fire at a slower pace than
fast-twitch muscle fibers and don’t fatigue
as rapidly and are suited for more sustained
workouts or events like marathons.
Regulating Fat-Storing Mechanisms
In a related study appearing in The Journal Of
Nutritional Biochemistry, Japanese research-
ers were looking for natural ways to curb the
rising obesity epidemic. In this study, some of
the subjects maintained a normal diet (ND)
and others were administered a high-fat
diet (HFD) for four weeks. At the end of the
four-week period the subjects were spilt into
four groups. Group one maintained the same
normal diet, and group two was fed the same
high-fat diet. However, group three con-

sumed the HFD plus two-percent red tomato
extract (RTE), and group four maintained the
HFD plus two-percent green tomato extract
(GTE) for an additional 13 weeks. At the com-
pletion of this phase of the study, the body-
weight of subjects on the high-fat diet plus
green tomato extract was significantly de-
creased to the level of those on a normal diet.
Interestingly, the bodyweight was only slightly
reduced in those on the high-fat diet plus
red tomato extract. These researchers noted
that the subjects who were administered the
green tomato extract realized a much more
substantial decrease in the expression of
a receptor called the peroxisome prolifera-
tor-activated receptor gamma. This receptor
regulates how fast one developing fat cell dif-
ferentiates or split into an additional fat cell.
The green tomato extract group also realized
reductions in the expression of the CCAAT/
enhancer-binding protein alpha receptor. This
receptor controls the expression of leptin, a
hormone made by fat cells, which regulates
the amount of fat stored in the body.
Moreover, and even more uniquely, sub-
jects in the green tomato extract group also
realized reduced activity of a protein in fat
called perilipin. Perilipin also known as lipid
