Quick answer

What to do first

Hunger and body weight are separate systems. If weight keeps falling while hunger is satisfied, increase the energy in your meals and reduce unnecessary exertion while you stabilize. Check the weight trend in the character information panel and compare available foods by calories, not just hunger reduction. Do not wait for an immediate weight change after one meal.

Choose useful food from what you have

Where nutritional values are visible, compare the energy supplied by the portions you actually eat. Packaged staples and richer foods can help when a diet built around low-energy forage keeps hunger down but weight falling. Availability matters more than copying an ideal shopping list.

Exercise and long, demanding trips affect energy needs. Plan recovery and food together rather than responding to weight loss with even more risky looting while already exhausted.

Maintain the improvement

Record the direction of the trend and change one thing at a time. Once weight is moving toward your goal, avoid continuing an emergency high-energy diet indefinitely. Hunger still needs attention even when you are trying to lose weight.

Food safety comes before calorie optimization. Do not eat rotten or unidentified items simply because you need more energy. If nausea or general health loss accompanies the weight problem, diagnose that separately rather than assuming calories explain everything.

Version notes & limits

Nutrition applies only when enabled by the world. Food values, activity and traits affect the result; older tables should not be used as a guaranteed current daily calorie target.

Nutrition decisions, not an exhaustive calorie database, exact daily menu or guaranteed rate of weight gain.
