Observations
Each observation Calk can show you has a page here: which data it uses, what it means, what you can do next, and the evidence behind it. Choose a topic below.
Weight Trend & Calorie Range
Individual weigh-ins move for many reasons. Calk uses repeated measurements and a calorie range to make decisions from the pattern.
Where Your Calories Come From
The weekly total becomes easier to understand when it is traced back to specific foods, meals and portion changes.
Protein, Muscle & Macro Balance
Calk separates total protein, protein per meal and protein's share of energy. Each view answers a different question.
Fats & Oils
Total fat, fat type and cooking fat answer different questions. Calk keeps all three visible.
Fiber & Carbohydrate Quality
The carbohydrate total does not show whether meals contain fiber-rich foods. Calk reads both.
Sugar & Carbohydrate Load
Calk reads the amount, source and repetition of sugar in the diary. It does not measure blood glucose.
Salt, Water & Potassium
Calk names the foods behind the salt estimate, checks whether drinks were recorded and shows how often potassium-rich foods appeared.
Minerals: Iron, Calcium, Magnesium, Zinc
Calk can describe mineral intake in the diary. It cannot measure absorption, blood levels or deficiency.
Vitamins & Food Sources
Calk can show which vitamin sources appeared in the diary. It cannot measure absorption, blood levels or deficiency.
Meal Timing & Rhythm
Calk describes when recorded food appeared and what accompanied it. It does not prescribe one correct eating schedule.
Food Quality & Cooking
The calorie total is only one view. Calk also shows how food was prepared, how dense it was and which patterns repeated.
Variety, Produce & Plants
Variety shows breadth. Calk counts what appeared in the diary and names the food groups that repeated or stayed sparse.
Small Changes to Repeated Meals
A useful change keeps the meal recognizable and changes one part that matters.
High Days, Recovery & Consistency
Calk reads the sequence—what contributed to a high day and what followed—without grading you.
Alcohol & Caffeine
Calk puts drinks back into the same record as food: amount, timing, repetition and the next recorded day.
Suggestions Built from Your Meals
Each suggestion names a food or meal from the diary and the specific gap it could address.
