Eating Late at Night May Trigger Weight Gain and Hair Loss

The much-documented link between hair loss and other conditions such as diabetes may mean that new research into the consequences of late-night eating has wider-reaching implications than scientists set out to find.

Experts at the Perelman School of Medicine at the University of Pennsylvania wanted to see how eating later in the day affected the body when set against more traditional meal times. To do this, they recruited nine adults to first eat three meals and two snacks between 8am and 7pm for eight weeks, and then switch this to a noon-11pm window for a similar time-frame.

Participants also undertook a two week “washout” period between the two to ensure there was no carry-over effect, and blood was drawn at key stages so that it could be analysed. Metabolic measures were taken, too, allowing researchers to assess changes in weight, metabolism and energy used.

The team found that eating later led to weight gain. Other tests showed that eating later led to metabolising fewer lipids and more carbs. Negative effects in terms of insulin, fasting glucose, cholesterol and triglyceride levels were also observed when participants were on the late-eating regime.

“These findings suggest that eating earlier in the day may be worth the effort to help prevent these detrimental chronic health effects,” said Kelly Allison, PhD, an associate professor of psychology in Psychiatry and director of Perelman’s Center for Weight and Eating Disorders.

The results of the study certainly don’t mean that a couple of late-night snacks will make your hair fall out; it’s more the idea that consistently eating late may lead to increased strain being placed on the body; in certain circumstances this cause adverse reactions including weight gain and hairloss.

Lifestyle and health issues play a part in hair loss


When the body is viewed holistically, there are several hair loss conditions that suddenly make a lot more sense. The food we eat, the way we exercise and a wide variety of other lifestyle-related elements all play a part in how the body hair included behaves.

Diabetes and Hair LossDiabetes, the risk of which appears to increase when adopting a late night eating routine, can lead to a temporary hair loss condition named Telogen Effluvium. Whilst the all-over hair thinning this causes only usually lasts for up to six months, it can still be an extremely difficult thing to go through in the aftermath of a diabetes diagnosis. Various medications, including some diabetes drugs can also lead to Telogen Effluvium as a side effect until the body gets used to the new drugs, too.

What’s surprising, perhaps, is that diabetes and instances of telogen effluvium can also speed up or exacerbate the genetic hair thinning conditions Male Pattern Baldness and Female Pattern Hair Loss in people who are predisposed, because of the way it affects hormone levels. With poor diets and sugar spikes so often linked to both diabetes and hair loss, it’s not hard to see how unhealthy eating patterns, now proven to have adverse effects by the University of Pennsylvania team, could feasibly lead to thinning hair, too.

Hair loss conditions need to be thoroughly understood and correctly diagnosed in order for experts to offer the best chances of recovery. There are clinically-proven hair loss treatment options available for both men and women with thinning hair who want to stabilise their shedding and promote regrowth.
