Advice plz

Hello, I I am new to low carb Keto .  A little about myself I am 44 years old female 5 foot 8 296 pounds I have lost 50 lbs so far but have stalled out lately and I'm trying to get back into weight loss.  for breakfast I was eating a smoothie made from a banana blueberries spinach and unsweetened almond milk.  for lunch I ate chicken and bell peppers with a little bit of shredded cheese on top. dinner was basically meat and a veggie.  Too many carbs and too little fat am I correct?  

Today I started with changing my smoothie to 1/2 avocado, 1/2 cup blueberries spinach and unsweetened almond milk.   More fat, less carbs.  I am considering adding a bullet proof coffee.   Any other advice, help you can offer?  What's a good yet simple app I can use? 

Thank you so much!
