The US recommendation for minimum protein intake is 0.8g of protein per kg of body weight... so at 97 kg, your minimum intake should be 77.6. So it sounds like you're in a good range! (The WHO minimum is only 0.45g protein per kg body weight, so even on your low days you're probably still at a healthy level.)
A lot of weight-loss plans recommend much higher protein intake than this anyway... I think it's because 1) if you're working out harder you're probably building some muscle so *maybe* you'll need the extra, 2) if you replace some fat with protein, you'll be eating less calories (4/g for protein vs 9/g for fat), and 3) protein tends to make you feel more full than carbs, or feel full longer, so replacing carbs with proteins may lead to eating less.
