Eat in moderation and ensure that your nutrient needs are met. Mostly protein based may mean that you're not getting enough nutrients from veg and fruits, which are essential for your well being too. Count your calories to know how much you're eating. it'll be a hassle for a while, but that will tell you how much you're actually consuming. Protein is calorie dense, so you may be eating more than you think.
Keep your daily activity level up - go for brisk walk first, add strength training into your routine .
Thank you!!
