A nutrition coach that adjusts to your weigh-in, not to a fixed formula.
Any calorie calculator gives you a number on day one. The problem shows up in week three, once your body has adapted and the number no longer holds. FitForm's nutrition coach starts from your estimated needs, then corrects them against your actual loss — one weekly weigh-in is enough to recalibrate the plan.

What an adaptive nutrition coach does
It starts from an estimate, then corrects it
The starting point comes from your data (height, weight, age, activity). Everything after that comes from reality: if loss is slower than projected the deficit tightens, if it is too fast it loosens to protect lean mass.
Macros, not just a calorie total
Protein, carbs, and fat are split according to your goal. The protein target is held first: it is what preserves muscle during a deficit and what keeps you full.
A concrete meal plan and a grocery list
The plan turns into real meals and a shopping list you can take with you. A plan you cannot convert into a supermarket basket is a plan abandoned in week two.
Rebalancing, not dieting
No food is banned and no deprivation phase is scheduled. The goal is a deficit sustainable over months, because duration is what produces the result.
Gym vs home
Your whole gym fits in your living room.
Weight loss doesn't come from a membership or a commute. It comes from your consistency — and nothing kills consistency like the friction of getting to the gym.

AI nutrition coach — frequently asked questions
Do I have to weigh every food?
No. The coach works with portions and meals rather than gram-level weighing. The data it genuinely needs to recalibrate is your weekly weigh-in, not the precision of each plate.
How is this different from a regular calorie calculator?
A calculator produces one number, valid for a few weeks at best. An adaptive coach compares your actual loss to the expected loss and corrects the target accordingly. It is the difference between a photograph and a feedback loop.
How much protein preserves muscle in a deficit?
The commonly cited range is 1.6 to 2.2 g per kilogram of bodyweight per day when trying to hold on to lean mass during weight loss. Our protein calculator gives a range matched to your weight and goal.
Does the nutrition coach handle specific diets?
The plan is built from your food preferences. For a medical condition, pregnancy, a history of disordered eating, or a prescribed diet, medical supervision remains essential: FitForm is a wellness tool, not a medical device.
