I haven't worked out at all this week and I feel like I've been gaining weight…
I checked your records — you did get one workout in this week! Your protein intake has been solid, and your weight is only up 0.3 kg from last week, which is basically noise. How about a 20-minute walk this weekend to get things moving again?
A walk sounds doable. How many calories would I burn?
At 150 lbs, a 20-minute walk burns roughly 80–100 kcal. Try Saturday morning and gradually increase the distance if it feels good
