Watching what you eat: does mindfulness work for binging and weight loss?


An early exercise for newcomers to mindfulness is to mindful-y eat a strawberry (a raisin, grape or other small fruit is allowable if strawberries are out of season).  Look at it, smell it, bite into it, feel its texture in your mouth, taste its juice, chew it, swallow it: be aware that you’re eating it (try not to be the one who swallows it straight away and has to get another one to do the exercise properly…).

If you’re a long-standing Elf-devotee you will not be a newcomer to mindfulness, which is popping up all over the woodland for use in stress, anxiety, depression, pain, and most recently substance misuse.

Mindfulness, the argument goes, helps you to be more aware and accepting of your internal experiences and yourself. You get better at recognising anger or sadness as different from hunger, you pay more attention to what you are eating and when you are full.  And it reduces stress, thus also decreasing the tendency to reach for the chocolate biscuits, so you’ll lose weight that way too.  It sounds like a pretty convincing argument, and it’s made by many online purveyors of weight loss techniques.

But what evidence is there that it works? The authors of a recent systematic review in the Eating Behaviors journal have kindly done the legwork for us by reviewing all the existing studies of mindfulness-based techniques for binge eating, emotional eating and weight loss.



The authors pre-registered their review online, and followed PRISMA recommendations. They searched appropriate databases using appropriate terms, and reviewed reference sections for articles they had missed.

Study selection

To be included, articles had to be original, published, include pre/post measures and an intervention, include mindfulness training in every session, and measure binge eating, emotional eating or weight loss. They were excluded if they included participants with anorexia or bulimia nervosa, those undergoing chemotherapy, case studies or those with a sample size of less than five.

Data extraction

Two authors independently evaluated selected studies for data extraction, including calculating within and between group Cohen’s d effect sizes. Information was then compared to check accuracy.

Risk of bias

Bias within studies was assessed, including whether outcomes were primary or secondary.

50 studies were identified as potentially relevant; only 14 met all the eligibility criteria; 11 were conducted in the USA. Length of interventions ranged from 6-16 weeks; age from 18-75; percentage of male participants from 10-37%, except in one study with 87.5% men. The majority used binge or emotional eating as a primary outcome measure, with recognised scales.

Only 7 studies had a control group of any sort. The number of participants in these studies ranged from 10-108. This summary includes only results where there was a control group for comparison, as comparing before and after without a control group is not meaningful. Results presented in the text and tables are contradictory as to which studies used binge eating and which used emotional eating as their outcomes. I have referred to the tables here, and scurried back to check the original references where possible.

Binge Eating

  • Was reduced in comparison to control group in 1 study (effect size of 1.10)
  • Was very slightly reduced in comparison to CBT in 1 study (effect size 0.31), and no different from CBT in another study

Emotional Eating

  • Was reduced in comparison to control in 2 studies (effect sizes 0.53 and 0.57) but not in a third


  • Did not change in relation to control in 3 studies
  • Weight loss was less than for CBT in one study
  • There was slightly less weight gain (sic) in comparison to controls in one study

Mindfulness is a promising intervention for many mental health conditions, but this review does not provide sufficient evidence to recommended it for treating or preventing binge eating


So can mindfulness work its magic on binging and emotional eating? The authors conclude that:

Mindfulness training may be an important contributor to positive changes in disordered eating.

I think this is an overstatement given the current literature. They acknowledge that the studies were small and that the outcomes used were different between studies, making comparison harder. They also acknowledge that, as with any review, it is likely that effects will be overstated, because negative or “null” results are less likely to be published.  However, in this case, the authors found and then discarded 10 unpublished studies, which is a pity.

Mindfulness may do many things, and is queuing up to take its place with CBT as the panacea of mental illness, but I don’t think it can lay claim to binge eating yet.

As to our waist lines: the authors state that:

A standard Mindfulness-Based Stress Reduction program alone does not appear to invoke weight change.

I agree entirely. Chew your strawberries slowly ladies and gentleman, and savour each one as you go. It may add to your enjoyment, but I’m afraid there’s no evidence that by doing so you will lose weight.

This review finds that Mindfulness-Based Stress Reduction

This review finds that Mindfulness-Based Stress Reduction will not help you lose weight. Healthy eating and regular exercise remain the order of the day!
