We’ll wait to see your veggie diet before pronouncing bacon fueled judgement from the top of Mount Keto
But… on the exercise front, it is often wise to do little to no exercise while you are fat adapting (4-8 weeks) since your body needs to divert all its energy and efforts to making that switch. While the Fitbit is good at knowing what you are doing, it is very flawed in understanding what you are actually achieving. Your actual calorie burn is very personal based on your genetic and physical capabilities and the quality/intensity of the exercise so it is somewhat irrelevant to your early keto journey for now. If you are raising your TDEE with exercise, all you are doing is increasing your calorie deficit which counter-intuitively is BAD on keto where you want to maintain your BMR while adapting and NOT lower it via a starvation response. You can reduce calories and increase burn later when fat adapted and using body fat (if you have any).
Looking forward to seeing veggie keto.
Now they are revealed, it seems good from a macro perspective, low carb, low protein, high fat. From a quantity POV, eating 2000 kcal and burning 2700 (if Fitbit is to be believed) is creating quite a deficit. As I said above, in the early stages, a calorie deficit works against you.
My advice would be, cut out the exercise and/or eat more (fat - e.g. the macadamias) and see what happens? You could also increase the protein which is not bad but definitely on the low side.
What is your weight and Lean body mass - should have asked that first
