Your character starts at 80 and drifts up or down with what you eat and how hard you work. Stray too far and you lose Fitness, damage and stamina. This page covers the weight bands, how the calorie pool works, what protein does, and how to move your weight on purpose. Updated for Build 42.21 Stable and 42.22 Pre-Release, November 2026.
| Band | Weight | Effect |
|---|---|---|
| Emaciated | 50 or less | Melee damage 40%, endurance recovery 30% (one source) |
| Very Underweight | 51 to 65 | -2 Fitness, melee damage 60% (one source) |
| Underweight | 66 to 75 | -1 Fitness |
| Normal | 76 to 84 | None |
| Overweight | 85 to under 100 | -1 Fitness, slower running |
| Obese | 100 or more | -2 Fitness |
Health damage starts at a weight of 35. Being Obese does not cost health by itself. The exact edges (50, 75, 85) differ by a point between sources.
Calories sit in a pool held between -2,200 and +3,700. You burn them every second, faster when active, and the burn scales with your body weight and the temperature. There is no fixed daily requirement, and no source gives a number per activity.
In Build 42 the level at which you start gaining weight moves with your weight. One guide gives it as 1,000 + (weight - 80) x 40: 400 at a weight of 65, 1,000 at 80 and 1,800 at 100 (one source). Older advice built on a fixed figure of about 1,600 is out of date.
Hunger and calories are separate. You can feel full while the calorie pool is still low, which is why a character living on vegetables keeps losing weight.
See exercise and fitness for training.
Eat the densest food you can find. Calories per item, from one Build 42 guide:
| Food | Calories |
|---|---|
| Whole pizza | 5,940 |
| Lard | 4,095 |
| Pasta | 3,360 |
| Butter | 3,200 |
| Mayonnaise | 3,000 |
| Rice | 2,880 |
| Peanut butter | 2,660 |
| Cereal | 2,360 |
| Ice cream | 1,680 |
| Chocolate | 850 |
See the food list for more.
Eat low-calorie vegetables and keep moving: cabbage 180, lettuce 54, zucchini 33, tomato 14, broccoli 11. Exercise burns the rest. Keep some protein in the diet so Strength training is not penalised.
| Moodle | Hunger | Effect |
|---|---|---|
| Peckish | 15% | None listed |
| Hungry | 25% | -1 carry capacity, healing 35% slower (one source) |
| Very Hungry | 45% | -2 carry capacity, healing 60% slower (one source) |
| Starving | 70% | -2 carry capacity and health loss (one source) |
On the good side the tiers are Satiated, Well Fed, Stuffed and Full to Bursting. Any of them gives +2 carry capacity and faster healing, and the last two stop you eating more. See moodles and cooking.
76 to 84. Inside that band you have no penalties. The character starts at 80.
Eat calorie-dense food such as lard, butter, pasta, rice and peanut butter. High carbohydrates or fats speed up the gain.
Eat low-calorie vegetables such as cabbage, lettuce and tomato, and exercise.
Yes. Protein between 50 and 300 gives 1.5 times Strength XP. Fitness XP is not affected.
Hunger and calories are tracked separately. Low-calorie food fills you up without refilling the calorie pool.
The Build 42 weight-gain formula and the 400 and 700 multipliers come from one guide; the official wiki page still describes an older build.
