Groci needs two: calories a day and protein a day. Tell it about you and it will do both, then shop for them.
You burn about 2,602 calories a day — 1,679 at rest, the rest from moving. Eating that holds your weight. Protein is set at 1.6 g per kg of body weight.
An estimate, not medical advice. Real burn varies by roughly 10% between two people with the same stats. If you are pregnant, managing a health condition, or want to lose a lot of weight, talk to a doctor or a dietitian first.
