Depends. How far along are you post op? My nutritionist said to keep my ratio around 45% carbs 30% protein and 25% fat. I eat around 1200 calories a day (but I'm also training for a half marathon and exercise a min. of 90 min a day and often more if I have a long run that day). So if you run the numbers back, carbs have 4 calories per gram, so does protein and fat has 9 calories per gram. At 700 calories that would be 315calories or 78 grams of carbs, 53grams of protein and 19 grams of fat. But looking at those numbers I would increase the protein to at least 60-80 grams and decrease the fat and carbs to accommodate that. So more like: 70g protein, 15g fat, 71g carbs. That's how I would spread the calories out if I were doing 700 cals a day. It ends up being 40% protein, 40% carb (obviously all complex carbs), and 20% fat.

I know that each doctor and nutritionist has a different plan. My nutritionist said at least 60 grams protein per day, no more than 20 grams carbs for each meal, and protein-only snacks. She is less concerned about the fat, but focus on whole foods and lean proteins.

Follow your nutritionist.

If you are VSG then you have a capacity restriction. At each meal choose the protein portion first followed by a veggie or fruit. Half the capacity should be the protein (ie if you can eat 8oz then the protein should be at leat 4 of those ounces). If you follow these guidelines your calories, carb and fat consumption will fall in line and stay balanced. No need to focus on calories.
