The Claim
The dropout rate among individuals following ketogenic diets averages 17%, with higher rates observed in stricter diets (e.g., classic KD at 22%) and in populations with serious underlying conditions such as cancer (35%), indicating that tolerability and adherence are major practical limitations to long-term use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among people on ketogenic diets, about 17% stop following them, but this rate rises to 22% for stricter versions and 35% for people with serious illnesses like cancer, showing that sticking to these diets long-term is difficult for many.

When the body runs mostly on fat instead of sugar, it produces chemicals that trigger nausea and fatigue. The brain interprets these signals as unpleasant, making the person want to stop eating this way. The stricter the diet, the stronger these signals become, and if the person is already sick, their body reacts even more strongly.
What the research says
1 studyStudy: Adverse events and tolerability of ketogenic diets – a systematic literature analysis
The study found that about 1 in 6 people quit keto diets, and those on very strict versions quit even more often — which matches what the claim says. It also suggests people with serious illnesses like cancer have a harder time sticking to it.
