Every few months a new diet shows up, promises everything, and delivers nothing. A TikTok creator decided to collect the receipts.
Dietitian Cassandra Lepore, known online as @dietitiancass, asked her audience to share the worst diet they ever tried, according to Bored Panda. The answers rolled in. Keto, raw vegan, egg fast, cabbage soup, the seafood diet (you see food, you eat it), and a deeply sad "anxiety and being poor in college." It is a buffet of regret.
At a glance:
- TikTok dietitian @dietitiancass asked users to share their worst diet.
- Keto, raw vegan, egg fast, and cabbage soup dominated the replies.
- Some users mentioned restrictive diet culture starting at a young age.
- One influencer diet was a punishing low-calorie plan with absurdly tiny portions.
- General practitioner Iris Gorfinkel told Bored Panda most diets fail because of shame, not calories.
The horror stories people actually shared
The cabbage soup diet left one user so traumatized by the smell that she claimed it would still make her throw up. A low-calorie influencer plan involved "2 tbsp of rice" and "3 almonds," which is not a diet, that is a hostage situation. The raw vegan two-year stretch turned one user into "the girl in the math problem buying 20 mangos." The egg fast went badly on day three, in a car, and we will leave the rest to your imagination.
One athlete described a very low daily calorie target that was nowhere near what her training actually burned. Another user was counting the calories in sticks of gum and worrying that five calories would make them gain weight. Several people said they were put on restrictive diets as children, including Slimming World at age 11.
Our analysis: why bad diets keep winning online
The simple answer is shame. General practitioner Iris Gorfinkel told Bored Panda that the "eat kale and move" approach makes people feel bad about themselves, which she says can drive weight gain in some cases. The diet industry profits when people feel broken. The cycle is that ugly.
There is also an attention economy angle. Extreme diets get clicks. A reasonable, balanced plan does not. So the algorithm keeps surfacing the worst options, and people keep trying them. The losers are the readers stuck in the loop. The winners are the rare creators, like Lepore, who use their platform to call it out.
Then there is the survey backing. A recent UK poll of 2,000 adults, cited by Bored Panda, found that a sizable share would not bother researching a new weight loss method before trying it. Among those who have tried a fad diet, the majority did not hit their goal, while some ended up heavier than when they started. Read those numbers together and the picture is grim. Most people walk in blind and walk out heavier.
What it means for you
Say you are tempted by a new viral diet. Read the plan out loud. If it bans entire food groups, prescribes tiny portions, or promises fast results, that is a red flag. Ask one question. Could I see myself doing this in five years. If the answer is no, your body will not either.
Quick gut-check before you start the next big thing:
| Red flag in a plan | Why it usually backfires |
|---|---|
| One food or food group rules everything | Nutrient gaps and cravings hit fast |
| Portions are measured in "tbsp" or "almonds" | Hunger wins, binge follows |
| Weight loss promised on a tight deadline | Sustainability |
| Shame is the marketing hook | Compliance collapses when willpower runs out |
Background: the science behind the struggle
According to Dr. Gorfinkel, more than 140 different genes influence body weight. Epigenetics and environment shape how those genes express. A Good Housekeeping reader poll cited by Bored Panda found that nearly half disagreed or strongly disagreed that they were happy with the way their bodies look and feel, and a striking share said they would shave years off their lives in exchange for their ideal body. That is not a willpower problem. That is a culture problem.
What to watch next
Watch the creator economy. As more dietitians like Lepore turn TikTok into a public confessional, expect the next wave of viral diets to get roasted in the same place they were born. The real story is not the cabbage soup. It is the loop between shame, shortcuts, and algorithms. Break it on day one.
Key takeaways
- The worst diets work on shame, not science.
- Extreme rules almost always fail long term.
- A plan you can maintain for years beats a plan that wows for a week.
- The body you have is shaped by more than what you ate last Tuesday.
Frequently asked questions
What was the worst diet mentioned in the TikTok thread?
There was no single winner. Cabbage soup, punishing influencer plans, raw vegan, egg fast, and restrictive childhood diets all came up.
Why do fad diets usually fail?
According to general practitioner Iris Gorfinkel, they often rely on shame and one-size-fits-all rules that ignore genetics and lifestyle.
How many genes affect body weight?
More than 140, per Dr. Gorfinkel, which explains why no single diet works for everyone.
Is dieting as a child common?
Several TikTok respondents mentioned being put on restrictive diets at a young age, including Slimming World at 11.
What is a healthier starting point than a fad diet?
Dr. Gorfinkel suggests starting with mental health and self-image, since those drive sleep, motivation, and food choices more than any rulebook.
