Hello TRACTORLADY ; sorry for the delay in replying, I've been cleaning my freezer and kitchen, and it took longer than expected
KETO is short for KETOGENIC
You don't need to know how the word was originated or derived, but just to know that a ketogenic or keto diet is one that is very low in carbohydrates, so it is also known as a low carb diet
The idea is that if you are consuming hardly any carbohydrates your body has to use up its existing stores of carbohydrates and also has less carbohydrate floating around in the body
And as the carbs are used up, so the body then uses its fat
Thus a keto diet is beneficial for anyone trying to lose weight, and for diabetics, or both
Instead of carbs people eat more fat & protein, plus veg - but be sensible about it
Obviously if you are consuming huge great bucketfuls of fat then you will gain weight anyway
And these should be the 'good' fats, like oily fish, avocados, and olive oil
You will notice that a keto diet is a change from earlier advice of eating bulky, starchy carbohydrates and reducing fat
With a keto diet you needn't be afraid of fat!
A keto diet is very popular at the moment, so there are lots of videos about it on YouTube, and also books - just Search Amazon!
There are so many that I haven't watched them all, but here is one explanation that is fairly straightforward -
'A keto diet for beginners' by Diet doctor
This channel adds a bit of fun and liveliness to the subject - 'Headbangers Kitchen'
Other than that it's a question of Searching YT for videos on keto diet, and keto diet for beginners, and watching a few
You will soon get the idea
