I agree with Saphire, you are definitely not eating enough fat.
It might be helpful to use a macro calculator. I have never needed this but many friends in this forum do use one with tremendous success.
Keep in mind that this plan is not a calorie deprivation plan. Eat as many calories as you need to be satiated. However, only 5% of those should be carbs and fewer than 15% should be proteins so that ALL the rest are from fat.
If you are still hungry at the end of any meal, eat more fat. Grass fed butter, literally by the spoonful. Coconut butter, macadamia nuts, an entire avocado. It’s insane the foods, the amount of fat, that I eat, personally everyday. I’m 5’2” and am under 120lbs and I eat a ridiculous amount of fat everyday. Fried eggs, sautéed veggies in butter, fatty fish and butter on everything.
The more fat I eat, the better I feel
Two things; I don’t supplement anything, I get everything in natural forms and two, I don’t use processed foods, including shakes or drinks ( except for Kombucha).
Having said all of that, it’s really a journey to figure out what works for you.
Keto is fat oriented, not just low carb
Over exercising is contraindicated while using keto (listen to the obesity code podcast)
I hope you find this helpful
Keep calm and keto on
