The Critical Importance of Meal Timing for Weight Loss

There have been two main changes in dietary habits from the 1970s (before the obesity epidemic) until today. First, there was the change is what we were recommended to eat.

How to Eat: Fast and Break-Fast

Fasting and Ghrelin – Fasting 29

It...

Fasting and Brain Function – Fasting 24

How does fasting affect brain function? There is very little reliable human data, but some very interesting animal data, as recently reviewed. There are many potential benefits. While I tend to focus on weight loss and type 2 diabetes, there are many other benefits, including autophagy (a cellular cleansing process), lipolysis (fat burning), anti aging...
