Of all things you can research and read about what makes people fat, The Obesity Code (by Dr Jason Fung, a Toronto-based nephrologist) is the new bible.
We as a society have been led to believe that weight gain is caloric imbalance – eating too much and moving too little. This is simply not true.
Everything about human metabolism, including the body set weight, is hormonally regulated. We don’t consciously control our body weight any more than we control our heart rates, our basal metabolic rates, our body temperatures or our breathing.
Forget about calories. Insulin is the front and centre in why we get fat.
What is insulin?
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use.
Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).
It’s not the biologically beneficial rise in insulin after a meal that makes people obese but the real culprit is the chronically high insulin (along with other hormonal disruptions).
So enter insulin resistance, Public Health Enemy Number One.
What is insulin resistance then?
As you know, one of insulin’s jobs is to help move glucose from the blood into the cells for energy. When blood glucose remains elevated despite normal or high levels of insulin, this is called insulin resistance.
The cells are resisting insulin’s pleas to take up glucose.
Once the body starts to get resistant to insulin, the entire hormonal system goes out of whack, and it can be a difficult process to reverse because of the knock-on effect of insulin resistance.
The formula goes: Damaging Diet => Hormonal Disruption => Fat Storage
So it isn’t just foods that raise insulin that make us fat, it’s foods that lead to insulin resistance that creates the real damage: obesity and obesity-related illnesses including type 2 diabetes.
How does insulin resistance develop?
Simply, bad diet.
What is a “bad diet”?
Mark my words, high carb diet, in a nutshell.
So reversing insulin resistance is the only way to lose weight in the long term.
Without fixing your insulin, you will be stuck on the yo-yo diet bandwagon and be exposed to other health complications.
So how you reverse it
Back to basics: fix your diet. Go low Carb/High Fat. Go Keto!
So in a nutshell, to lose weight, you must keep your insulin and glucose level stable and healthy.
To maximise fat burning, two pathways: go low carb/high fat and do fasting.
