HYDERABAD — In a 2025 study of 345 information technology employees in the city’s IT hub, 89 worked outside the standard 9 am to 5 pm shift, and 241 reported sleeping fewer than seven hours a day. For Vinay Kumar Nevatia, a Hyderabad dietician who plans around everyday Indian food, those figures sketch the people who keep asking him a question standard advice never answers: when, exactly, is dinner?

“A lot of diet advice assumes a day that starts at seven,” Nevatia says. “Breakfast, lunch, dinner, bed. Someone on a client shift asks what dinner means at 2 a.m., and I’m out of tidy rules. I’m not sure anyone has the full answer.”

What the research says, and how little it settles

The headline association is modest. A 2015 meta-analysis pooled 12 observational studies with 226,652 participants and reported an odds ratio of 1.09 (95% confidence interval 1.05 to 1.12) for diabetes among people who had ever done shift work. The authors called it an association. They are based in China and the abstract gives no India breakdown, so this is foreign evidence. A separate overview by Lowden and colleagues adds that some metabolic complaints in shift workers may be linked to diet quality and irregular eating times, but stress, disrupted circadian rhythms, sleep debt, inactivity and too little rest are likely to play a part.

“A ratio like that describes crowds,” he says. “It’s a reason to take night-shift meals seriously. It isn’t a verdict on the person in front of me.”

The most direct test of timing is smaller still. In a randomised US laboratory study, 19 healthy adults aged 18 to 35 went through a 14-day protocol that included simulated night work. Among those who ate on a night schedule, the blood sugar response to a test meal rose 19.4% from their own baseline (95% confidence interval 4.7% to 34.2%). Among those whose meals were restricted to daytime hours, the change was not significant. The authors say studies of real shift workers are still needed.

Would he tell a night-shift worker to eat only in daylight on the strength of 19 people in a lab? “No,” Nevatia says. “I haven’t seen what that looks like in a flat in Gachibowli, with a family, a pressure cooker and a cab at 8.40.”

Official advice on timing and food

Two bodies word the basics differently, and Nevatia keeps them apart. ICMR-National Institute of Nutrition’s Dietary Guidelines for Indians advise restricting meal frequency to two to three times a day and not snacking in between. They describe a healthy meal as generous vegetables, adequate whole grains and pulses or beans, modest nuts or seeds, some fruit and plain curd, with little added sugar, oil or salt. A US page for night-shift nurses, from NIOSH at the CDC, advises avoiding or reducing food between midnight and 6 a.m., eating three meals per 24 hours (more often if energy dips), and avoiding sugar-rich and low-fibre carbohydrate foods when staying alert matters, because it says they can increase sleepiness. That page is foreign guidance, written for nurses.

He approaches meal timing as a question about the person’s day.

“‘Don’t eat after eight’ is the advice I disagree with most,” he says. “It’s written for someone asleep by ten. On a 9 p.m. shift, a midnight-to-six rule means skipping the middle of your working night. Some people manage that. Plenty can’t. What I take from both documents is the shape, a few anchored meals, not the clock times. I could be wrong about that.”

What goes on the plate at 2 a.m.

In a consultation, everyday Indian meals get much messier. “I ask what you’ll actually eat at 3 a.m.,” he says. “Dal, a sabzi, a roti made with whole wheat or millet, curd, a green-gram pesarattu if there’s time. A salad box that needs a plan and a fork doesn’t last the week. And the chai? I care less about the number of cups than what sits next to them. Irani chai with a packet biscuit is the habit I’d look at.”

First questions Vinay Kumar Nevatia asks about a Hyderabad shift

Hyderabad is an odd place to argue about this, because the national guidelines are written here: ICMR-NIN publishes them from Tarnaka. The same document does not treat outside food as one category. It calls street foods generally wholesome and fresh, with a warning on hygiene, and says most made-to-order fast food is fresh, though some items, such as milkshakes, chips, pizzas, burgers and fries, are flagged as unhealthy because of fat, sugar and salt content or ultra-processing.

Note: Source — ICMR-NIN, Dietary Guidelines for Indians, 2024, pp. 3 and 95-96. https://nin.res.in/dietaryguidelines/pdfjs/locale/DGI_2024.pdf

Vinay Kumar Nevatia builds every plan for night-shift meals from the person’s clock, not the calendar: when they sleep, how long the commute runs, when the cab leaves, when the canteen shuts, what the delivery app shows at 1 a.m. He plans two or three anchor meals around the sleep window, then asks what happens on the night those fall apart. Biryani isn’t banned. He asks what arrives with it, and when. “Never eat outside” doesn’t survive a shift where the canteen closes at midnight, he says.

Where the advice runs out

Most of this, including the evidence on meal timing, is association and small samples, plus guidance written for other workforces. The Hyderabad study that opened this article was cross-sectional. Its authors note that 85.2% of the sample was male, that behaviour was self-reported and unverifiable, that selection and information bias were possible, and that longitudinal studies are needed to establish a causal relationship.

None of it tells a person with a medical condition what to do on Tuesday night. Rotating rosters are hardest to plan, with no single sleep window. Meals tied to medication or insulin timing, pregnancy and any history of disordered eating each change the question. On the last, he is blunt: a rule that says don’t eat between midnight and six can be exactly the wrong one.

The fourth night

A night-shift plan, he says, only counts if it survives the fourth night, when the cab is late, the canteen is shut and the dal in the dabba has gone cold. “Cold dal is a plan with no future,” he adds, “and I’ve written a few of those.” That is the standard Vinay Kumar Nevatia applies to every plan he writes, and the ones that pass are usually dull: the same few everyday Indian meals, packed before the cab arrives.

General information, not medical advice. This article summarises research and one dietician’s general approach. People with diabetes, pregnant or breastfeeding women, anyone on regular medication and anyone with a history of eating disorders should consult a qualified doctor or dietician before changing when or what they eat.
