How Zenith handles nutrition
Not a calorie counter.
An adaptive nutrition engine.
Most nutrition apps are databases with a logging UI bolted on. You find your food, log it, and hope the math works out. Zenith starts from the opposite direction.
It calculates your TDEE from your stats and goal, sets protein, carb, and fat targets that match the training phase, then generates a 7-day meal plan around those targets. When your training changes — a heavy week, a deload, a skipped session — the nutrition plan adjusts with it.
Photo logging exists for the days you just want to snap and move on. The AI estimates macros with a confidence score. You accept, adjust, or override. Nothing is hidden.
