QUOTE from Dr Fung (emphasis mine):
“The simple truth is that weight loss comes down to understanding the hormonal roots of obesity. Insulin is the main driver. Obesity is a hormonal, not a caloric imbalance. There are not one, but two main considerations for proper food choices:
What to eat
When to eat
In considering the first question, there are some simple guidelines to follow.
Reduce intake of refined grains and sugars,
moderate protein consumption and
increase natural fats.
Maximize protective factors such as fiber and vinegar.
Choose only natural, unprocessed foods.
In considering the second question, balance insulin-dominant periods with insulin-deficient periods: balance your feeding and fasting.
Eating continuously is a recipe for weight gain. Intermittent fasting is a very effective way to deal with when to eat.
In the end, the question is this: If you don’t eat, will you lose weight? Yes, of course. So there is no real doubt about its efficacy. It will work.
There are other factors that affect insulin and weight loss such as sleep deprivation and stress (cortisol effect). If these are the major pathways of obesity, they must be directly addressed, not with diet, but with techniques such as proper sleep hygiene, meditation, prayer or massage therapy.” 
NOTE (my commentary)
The simple truth is that weight loss comes down to understanding the hormonal roots of obesity. Insulin is the main driver.
balance insulin-dominant periods with insulin-deficient periods: balance your feeding and fasting.
