Everything else on this site describes a way of eating that removes entire food groups. This article is about who should not go anywhere near it, and it is deliberately the last word rather than a footnote.
Depression and disordered eating overlap heavily
They occur together far more often than chance would explain, in both directions. Depression raises the risk of disordered eating; eating disorders carry very high rates of depression. If you have experienced either, the other is more likely than it would otherwise be.
That matters here because a diet that eliminates whole categories of food is, structurally, a set of rules about what you are not allowed to eat. For most people that is just a diet. For someone with a history of restriction, it is a familiar shape, and a legitimising one — a reason to restrict that sounds like health rather than illness.
Who should not try this
Without specialist advice, this is not for you if:
- You have or have had an eating disorder of any kind, including one never formally diagnosed.
- You are underweight, or losing weight without meaning to.
- You find food, eating or your body difficult to think about calmly.
- You are pregnant or breastfeeding.
- You have type 1 diabetes, or liver, kidney or pancreatic disease.
- You are under eighteen.
Warning signs once you have started
Some of these are the ordinary business of changing how you eat. Together, they are a reason to stop and talk to someone.
- The rules are getting stricter on their own, without a reason you could explain.
- Eating anything outside them produces guilt rather than a shrug.
- You are avoiding meals with other people to avoid explaining yourself.
- You are pleased by weight loss you did not set out to achieve.
- Thinking about food is taking up more of the day than it used to.
- Mood is getting worse rather than better.
The last one deserves emphasis. Under-eating reliably lowers mood. If this way of eating has left you eating less overall — which is common, because it is monotonous and appetite falls — then the thing you are doing for your mood may be working directly against it.
There is no weight-loss content on this site
Deliberately, and it will not be added. No calorie targets, nothing to weigh, no before-and-after pictures and no testimonials. People lost weight in the studies described here and that is reported as a study finding, not as a selling point.
A site about depression that also sold weight loss would be doing something careless with a group of people who do not need it.
Where to get help
If any of this is familiar, please speak to your GP. Eating difficulties are common, treatable, and nothing to be ashamed of — and you do not have to be at any particular weight, or have any particular diagnosis, to deserve help.
Beat is the UK’s eating disorder charity and offers free, confidential support, including a helpline and online groups. Your GP can refer you for specialist treatment.
If your mood is the more pressing problem, the Samaritans are on 116 123, free and open at any hour. For urgent medical help that is not an emergency, call NHS 111. In an emergency, 999.
The honest summary
This site describes an emerging research area and a restrictive way of eating, with the evidence reported as it is: one modest randomised trial in depression, some more striking findings in other conditions, a three-person case series, and a review that flags real risks and declines to recommend the diet long-term.
For some people it is a reasonable thing to discuss with a doctor. For others it is a bad idea, and this page exists so that nobody has to work out which group they are in by themselves.
Where to go next
General education, not a diagnosis and not a treatment. If your mood has been low for weeks, your GP is the next step.
