user: I've been trying to adjust my diet and fitness plan, and I really need to get my nutritional needs dialed in. I'm a 30-year-old guy, weigh about 100 kilograms, and I'm 170 centimeters tall. I'm not the most active person – my activity level is pretty low, around 1. I want to lose weight. Can you calculate what my daily nutritional intake should be?
