If you listen to his dietary advice, about frequency, types of food to eat, he is basing his knowledge on historic Yogic tradition.
The western mind asks for explanation, that is the logic. Faith is less relevant than scientific proof.
I have been advocating, longer periods of giving your metabolism a rest, completing your days nutrition within a 10 hour period.
Here I am quoting from a scientific article published in the Proceedings of National Academy of Science in the USA 2014, I am not editorializing but quoting verbatim from their article. If you watch Sadhguru first and read the excerpts from the article second, you would see the connection between the Spirit and the Science.

Meal frequency and timing in health and
disease
The most common eating pattern in modern societies,
three meals plus snacks every day, is abnormal from an evolutionary
perspective. Emerging findings from studies of animal models and human subjects
suggest that intermittent energy restriction periods of as little as 16 h can
improve health indicators and counteract disease processes. The mechanisms
involve a metabolic shift to fat metabolism and ketone production, and
stimulation of adaptive cellular stress responses that prevent and repair
molecular damage.
Some of the advice provided by physicians and
dieticians to their patients is consistent with the current scientific
evidence, including the benefits of vegetables, fruits, fiber, nuts, and fish,
and the value of reducing or eliminating snacks. However, there are many myths
and presumptions concerning diet and health, including that it is important to
eat three or more meals per day on a regular basis
Unlike modern humans and domesticated animals, the
eating patterns of many mammals are characterized by intermittent energy
intake. Carnivores may kill and eat prey only a few times each week or even
less frequently , and hunter-gatherer anthropoids, including those living
today, often eat intermittently depending upon food availability . The ability to function at a high level, both physically and mentally,
during extended periods without food may have been of fundamental importance in
our evolutionary history.
A metabolic shift to ketogenesis that occurs with fasting bolsters neuronal bioenergetics. Liver glycogen stores are typically depleted within 10–12 h of fasting, which is followed by liberation of fatty acids from adipose tissue cells into the blood. The fatty acids are then transported into liver cells where they are oxidized to generate Acetyl-CoA. Acetyl-CoA is then converted to 3-hydroxy-3-methylgluaryl-CoA, which is in turn used to generate the ketones acetoacetate and β-hydroxybutyrate (β-OHB). The ketones are released into the blood and are transported into various tissues, including the brain, where they are taken up by neurons and used to produce acetyl-CoA. Acetyl-CoA enters the tricarboxylic acid (TCA) cycle to generate ATP.
Obesity has also become a major health problem in
dogs and cats, which are often fed ad libitum ,
and even laboratory rodents can often be considered overfed and sedentary .
Indeed, animals in the wild and hunter-gatherer humans rarely, if ever, suffer
from obesity, diabetes, and cardiovascular disease
Compared with those fed ad libitum, the lifespans
of organisms from yeast and worms, to mice and monkeys can be extended by
dietary energy restriction .
Data collected from individuals practicing severe dietary restriction indicate
that humans undergo many of the same molecular, metabolic, and physiologic
adaptations typical of long-lived CR rodents .
IER/fasting can forestall and even reverse disease processes in animal models
of various cancers, cardiovascular disease, diabetes, and neurodegenerative
disorders
The high rates of childhood and adult obesity and
the diseases they foster is a major burden to our society. As findings from
basic research studies and controlled interventional trials accrue, consensus
recommendations for healthy patterns of meal frequency and diurnal timing may
eventually emerge. If sufficient evidence does emerge to support public health
and clinical recommendations to alter meal patterning, there will be numerous
forces at play in the acceptance or resistance to such recommendations. First
and perhaps foremost is cultural tradition. Three meals plus snacks daily has
become the norm during the past half-century, such that a majority of American
children are accustomed to this eating pattern. Second, the agriculture, food
processing, food retail, and restaurant industries and all of the affiliated
industries that serve or promote food—from airlines to concert stadiums to
television cooking shows to advertising and others—still all have established
practices and financial interests and these interests may affect receptivity to
proposed shifts in eating patterns and potential decreases in total food
purchased. Third, the willingness and ability of the American health care
system, including medical training and practice, to emphasize prevention and
lifestyles will be a key factor in success or lack thereof.
