The whole idea that low fat high complex carbs is a healthy way to eat has been around for 30 or 40 years. The evidence to the contrary is growing all the time, yet the so called professionals still churn out the old advice.
Finally someone can see that the rise in obesity levels coincides with the rise in processed and refined foods and our increased carb consumption. Someone also needs to make the same connection with the corresponding rise in type 2 dieabetes. Zoe Harcombe isnt the first person to make this connection though, there is an absolute ton of research out there that points in this direction.
Fat isnt the enemy, insulin is the enemy. Carbs convert to glucose, glucose causes insulin to be released, insulin forces our bodies to store the glucose in our fat cells, converting it to yet more fat. Get rid of carbs, insulin levels out, and your body burns the fat instead of storing it. Its more complex than that of course, but thats the problem in a nutshell.
Also, eating carbs causes you to crave more carbs. Eating protein does not do that. And this is again all to do with the effect of glucose levels and how your body deals with it by producing insulin, causing the high/low glucose and insulin responses. Protein does not convert to glucose in the way that carbs do.
The whole low fat diet revolution has been around so long now that its ingrained in us to believe. Its the tooth fairy im afraid, and we need to wake up to the truth, and the real scientific evidence.
I have been dieting for 30 odd years, following all the 'good' advice about low fat diets, and all that has done to me is make me bigger and bigger, and type 2 diabetic to boot. Low carb eating was forced on me in May this year, and ive lost 5 and half stone as a result. 5 and half stone in barely over 5 months, somethings got to be going on.
