Activation of SIRT1 will extend lifespan and can be particularly effective in conjunction with caloric restriction
. SIRT1 blocks tumor growth and cell death, and protects human cells from gamma radiation.
EFFECT OF CHRONIC CALORIC RESTRICTION
ON THE CIRCADIAN REGULATION OF PHYSIOLOGICAL AND BEHAVIORAL VARIABLES IN OLD MALE B6C3F1 MICE.
"There has been great interest in finding compounds that mimic the benefits of caloric restriction
that could be used to delay the onset of age-associated problems and/or diseases," Luigi Puglielli, MD, PhD, who studies aging at the University of Wisconsin, Madison, and was not involved in this study, said.
This paper, the latest to draw from the data, primarily examines how moderate caloric restriction
impacts heart health and how it may potentially prevent aging-related decline.
But is caloric restriction
the real anti-aging secret?
However, in our study the participants were kept on caloric restriction
after fasting and also provided with fibrous oatmeal (White oats).
Recent aging studies have shown that caloric restriction
and fasting have a prolonging effect on lifespan in model animals," says first study author Dr.
In human studies, garbanzo beans support healthy weight control and weight loss, even without caloric restriction
. (3,4) Part of this effect may be because garbanzo beans encourage the feeling of fullness after a meal, along with beneficial effects on metabolism.
Fasting is believed to help in this goal because of the effects that caloric restriction
and extended periods without food have on metabolism, or simply because people eat less during the restricted-feeding window.
In this study, one group of men ate a calorie-restricted diet for 16 weeks straight, while a second group alternated two weeks of caloric restriction
with two weeks of energy balance (eating the number of calories needed to maintain weight) for eight cycles.
Body weight was determined at day zero and weekly during the 56-day caloric restriction
for all mice.
