Blood donation and fever numbers are close to real figures.
Why we say that›
Tapeworms, cancer tumors and bad sunburns do not reliably burn hundreds of extra calories a day.
Blood donation burns around 600-700 calories and fever raises calorie burn by about 7% per degree. No good evidence supports the specific numbers for tapeworms, shivering, catastrophic sunburn or cancer tumors. The reel frames life-threatening conditions as fun, cheap ways to lose weight.
Based on only a few sources, so read this as a first look, not the last word.
Blood donation and fever numbers are close to real figures. The reel leaps from that to present tapeworm infection, severe sunburn and cancer as safe, desirable calorie burners with specific high numbers that lack supporting evidence.
Tapeworm infection is a serious health risk that can lead to malnutrition, organ damage and death, not a cheap weight loss method.

Claims
2 true · 4 unchecked
- Couldn't check
Tapeworms burn 500 or a thousand calories per day.
What's actually true
We couldn't verify this claim with a reliable source. No sources confirm this specific number. Tapeworms are dangerous parasites that can cause serious health problems.
- Couldn't check
Every extra degree of fever burns 7% extra calories.
What's actually true
Fever increases resting energy expenditure by about 7% per degree Fahrenheit.
- Couldn't check
A crazy catastrophic sunburn causes you to burn an extra 400 plus calories per day.
What's actually true
No evidence supports an extra 400 calories per day from severe sunburn. Healing costs are minor or negligible.
- Couldn't check
Cancer tumors burn an extra thousand plus calories per day easily.
What's actually true
Tumors increase overall calorie needs in cancer patients through cachexia, but the exact extra burn varies widely by type and stage and is not typically a fixed thousand calories easily.
- True
Donating blood burns 600 to 700 calories.
What's actually true
Studies and blood centers confirm you burn around 650 calories per pint donated.
- True
Shivering from being cold burns 100 to 400 extra calories per day.
What's actually true
Cold exposure can increase calorie burn by around 188 calories a day on average with shivering, but the range and daily total vary.

From reporting
What else it leaves out (2)›
- Severe sunburn and cancer are dangerous medical conditions requiring treatment, not calorie-burning strategies.
- The specific calorie numbers for tapeworms, catastrophic sunburn and cancer tumors come from unverified internet tropes rather than medical studies.

Burn calories Worried about skipping a workout after donating blood?
you can burn up to 650 calories per pint of blood donated (UC San Diego research cited; spread over weeks).
cold exposure significantly boosted calorie burn ... with an average increase of around 188 calories a day from acute (short-term) exposure (shivering produces up to 5x resting heat; range aligns with per-hour estimates).
Fever increases REE by approximately 7 percent per degree Fahrenheit (or about 13 percent per degree Celsius) (direct corroboration of the per-degree rule).
What are the dangers of the tapeworm diet?
While weight loss may seem tempting, tapeworms can be very dangerous.
