Calcium intake affects how hungry you feel. Getting enough calcium reduces total food intake.
See the scientific wording
Calcium intake plays a role in appetite regulation, and satisfying calcium needs reduces overall food intake.

What the research says
1 study reviewedSupporting (1)
Randomized Controlled TrialHuman2009
The study found that women who didn't get enough calcium ate less fat and lost more weight when they took calcium supplements, suggesting that calcium helps control appetite and reduce eating.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When the body does not get enough calcium, it creates a strong urge to eat foods that contain calcium. These foods are often high in fat, so the person eats more fat and gains weight. Taking calcium supplements stops this urge, so the person eats less fatty food and loses fat.

Calcium intake affects how hungry you feel. Getting enough calcium reduces total food intake.
Mechanism
1 studyThe body develops a strong desire for calcium when it is low on it, and this desire makes people eat more fatty foods that contain calcium. Taking calcium supplements stops this desire, so people eat less fat and lose weight.
When the body does not get enough calcium, it creates a strong urge to eat foods that contain calcium. These foods are often high in fat, so the person eats more fat and gains weight. Taking calcium supplements stops this urge, so the person eats less fatty food and loses fat.
Low calcium intake leads to a calcium-deficient state, activating a physiological drive for calcium-specific appetite.
Calcium-specific appetite biases food selection toward calcium-rich foods, which are often high in fat, thereby increasing lipid intake.
Increased lipid intake contributes to positive fat balance and hinders fat mass loss during energy restriction.
Calcium supplementation corrects calcium deficiency, reducing the calcium-specific appetite, thereby decreasing lipid intake and facilitating fat mass loss.

Calcium plus vitamin D supplementation and fat mass loss in female very low-calcium consumers: potential link with a calcium-specific appetite control.
The study found that women who didn't get enough calcium ate less fat and lost more weight when they took calcium supplements, suggesting that calcium helps control appetite and reduce eating.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Randomized Controlled Trials on Calcium Supplementation and Appetite Regulation
Systematic review and meta-analysis of RCTs comparing calcium supplementation (any dose, duration) vs placebo in adults, with outcomes including subjective appetite ratings, ad libitum food intake, and total energy intake
Double-Blind RCT of Calcium Supplementation vs Placebo on Appetite and Food Intake in Healthy Adults
Double-blind, placebo-controlled randomized trial with 200 healthy adults aged 20-50. Intervention: 1000 mg calcium (as calcium carbonate) daily for 8 weeks. Placebo: identical tablet. Outcomes: visual analog scale appetite scores (hunger, fullness, desire to eat) at baseline and weekly, ad libitum buffet meal intake at weeks 0, 4, 8, and total daily energy intake via food diaries
Prospective Cohort Study of Dietary Calcium Intake and Changes in Appetite and Food Intake Over 1 Year
Prospective cohort of 500 adults aged 30-60, assessed at baseline and 12 months. Dietary calcium intake measured by food frequency questionnaire and 24-hour recalls. Appetite assessed by validated questionnaire, food intake by 3-day food diaries. Outcomes: change in appetite scores and total energy intake
Effect of Calcium Infusion on Hypothalamic Appetite-Regulating Neurons and Food Intake in Rats
Male Sprague-Dawley rats (n=40) randomized to intracerebroventricular infusion of calcium chloride (0.5, 1, 2 mM) or artificial CSF for 2 hours. Measure food intake 0-24h, c-Fos expression in arcuate nucleus, and plasma ghrelin/leptin levels
