Having issues eating enough.

I’m fairly new to IF, I’ve been 16:8 now 18:6 for almost 2 months now. Last month I started hitting the gym 5 days/week and am killing it; reaping all the benefits of IF, however, my problem right now is eating enough. Getting through my fast is super easy for me, eating is the hard part.

I usually make a pretty thick smoothie/shake right after my workout to break my fast with 40-50 grams of protein (goal is 100-130g protein per day), but then I find myself feeling really full for the next couple of hours and end up eating an actual meal later and later. Now I can’t even finish my meal and am worried I might start hitting a calorie deficit or relying too heavily on protein shakes (I basically force down another before bed if I’m still too full to continue eating).

Any advice or tips? I’m mid-30s F, vegan and keto. I used to be a chef and cook all my meals, usually stir-fry, spinach salads or soups; all with a bunch of tofu. I used to snack on nuts/seeds and sugar free chocolate but can’t even get to that anymore. I want to eat more, but just feel too full. Help!
