Weight Loss & Liver: How Dehydration Slows Fat Loss- Thomas DeLauer…
Dehydration and Fat:
Organ function- If your kidneys become dehydrated, their main job of filtering the blood becomes inhibited, and so passes a lot of the job onto the liver. One of the liver’s functions is to metabolize stored fat in the body, and therefore only has half the fat burning capacity if your kidneys are malfunctioning from dehydration. Liver is babysitting two kids instead of just one.
Endocrine system- Growth hormone (hgH) is a potent fat burning hormone. It binds itself to the receptor sites of fat cells and breaks down triglycerides, shrinking the fat cell.
However, hgH production is hugely reduced when the body is dehydrated, limiting fat metabolism.
Cognitive function- The brain is made of roughly 80% water, and is therefore very sensitive to changes in water level. Just 2% dehydration can reduce cognitive function by up to 30%.
This can lead to a feeling of tiredness and fatigue, which negatively promotes a lack of motivation to exercise and eat correctly – indirectly hinders fat burning (1)
Study- One study looked at dehydration and obesity and used urine samples provided for the U.S. National Health and Nutrition Examination Survey 2009-2012 from 9,500 participants ages 18 to 64. The study found that nearly one-third of participants were inadequately hydrated and that the odds of being obese were 1.59 times higher for people who were not well-hydrated – also found that a lack of proper hydration was associated with higher body mass index. (2,3)
Improve Your Hydration- Drink a full glass of water on waking. Six to eight hours of sleeping leaves us dehydrated first thing in the morning. The worst thing you can do at this time of the day is immediately drink tea or coffee – they act as diuretics and will dehydrate you even further. It is important to include electrolytes (salt) in your water to mitigate the risk of hypernatremia (condition where the sodium concentration of your blood becomes too low due to drinking too much plain water when dehydrated) By doing this you’ll also rehydrate more effectively as the salt helps the water pass from your gut into the blood and keeps it there (if you only drink plain water when you’re severely dehydrated you’ll only absorb 50% of the amount you drink.) (1,4) Highly polarized water is attracted to positively charged sodium in the blood.
