• Participants were less full• Bodies released less
ghrelin, hormone regulating appetite

• Participants were more full• Bodies released more

The surprising part?
All the smoothies had the same number of calories.

Sleep
fMRI of Non-REM versus Deep (REM) Sleep

Rats allowed to sleep but deprived of REM
were dead in 33 days.

During Sleep:
• Growth hormones are released• Neurotransmitters are synthesized• Protein breakdown in cells slows• Toxins removed• Long-term memories are formed

Hydration
Your Brain is 60% Water
Dehydration causes shrinkage.
Source: UCSF
Diameter of an axon is directly related to signal transduction capacity.
Dehydration:

• Slows Neuron Processing Speeds• Impairs Short-Term Memory• Attentional Deficits

Healthy Gut There are more non-human cells in your body than human ones.
100 Trillion Bacteria Responsible for nutrient absorption and influence production of hormones like Serotonin, 90% of which is in gut.
