n.b., if you're a 5'9", slightly-overweight 50 year old man with an office job level of activity, you'll not be in a caloric deficit with 2000 Cal/day according to https://tdeecalculator.net/ https://tdeecalculator.net/ Actual nutrition -- getting the right micronutrients and such -- is the most questionable part of my interpretation, but it can still feel true to someone, they can still feel like their body just isn't getting what it's telling them it needs to feel right.
