One of the primary goals of the ketogenic diet is to lower insulin levels so that fat stored within cells can be utilized for energy. This is why keto is low carb.
Stevia does not do much to blood sugar levels, but blood sugar is only an easily measured proxy for insulin and Stevia does have an impact on insulin levels just as if you had consumed sugar.
I would not use Stevia, nor any sweetener.
Fruit? Once in a blue moon I will eat a bit of bitter berries or have a spritz of fresh lime on fish. I can’t recommend any fruit other then foods that are technically fruits that we are unlikely to think of when we talk about fruit; an avocado.
Watching calories? As long as your are keto, you can eat very few calories and watch a great volume of calories melt off your body.
Drink when thirsty.
Exercise if you enjoy it.
Trust that your body is smarter then your doctors.
There is also nothing wrong with feeling a bit hungry. It is not a sin and won’t hurt you, but gluttony will eventually kill anyone. I am not even hinting that you are a glutton, I am just pointing out that hunger is natural and their is nothing at all wrong with skipping meals and having an appetite at dinner time. Eat a bit of food, slowly, and then just stop when you no longer feel hungry, or even before. No worries, It is not like your hunger will never come back and one of the great joys of keto is that many people experience only modest hunger while loosing a great amount of body fat. Your energy needs are being met by the body fat you are burning.
Set a hunger goal … try to feel hungry at least 8 hours each day. Embrace that feeling, enjoy that feeling.
I always find it amusing that in America we have so many fat kids and the government has massive “hunger” programs. I would assert that we would be better off with more kids experience a git of hunger then with so many fat kids. Experiencing hunger is not something that should be banished from our existence.
