The order you eat things in: worth it, or a social media myth?

It isn’t a myth, but it is a small effect on a small evidence base. Eating vegetables and protein before carbohydrate lowered the rise in blood glucose after a meal in short studies of a few dozen people. Nobody has shown it gives you more energy, and in type 2 diabetes there was no evidence it adds to standard advice.

Where did the food order idea come from?

Mostly from one small study. In 2015, Shukla and colleagues gave 11 people the same meal on two days a week apart: ciabatta and orange juice first, then chicken, salad and broccoli fifteen minutes later, and the other way round. When the chicken and vegetables came first, blood glucose after the meal was lower at 30, 60 and 120 minutes.

Look at who those 11 people were. All of them had type 2 diabetes and all were taking metformin. The authors called it a pilot study, and it measured glucose and insulin, nothing else. That is a promising signal in a small, specific group. It has since been passed around as advice for everyone.

Does food order work if you don’t have diabetes?

In the short term, it seems to. A review published in 2026 searched more than two thousand records and found six studies in healthy adults, 107 people in total, aged roughly 20 to 37. Most of them found that eating vegetables, fruit or protein before carbohydrate lowered the glucose rise after the meal compared with eating carbohydrate first or everything mixed together.

The reviewers were clear about the limits. Most of the studies only measured short term responses after eating, which makes it hard to say anything about long term glucose control, and the participants were mainly healthy Asian adults. With 107 people spread across six studies, the samples were small too. And because these were glucose studies, none of what they summarised tells you whether anyone felt different afterwards.

Does it make a difference over months?

The best answer we have comes from people with type 2 diabetes, the group it was first tested in. A 2022 review pooled eight trials with 230 people, including some that ran for more than two months. Eating carbohydrate last made slight to no difference to HbA1c, the long term blood glucose measure, and the certainty of all the evidence was rated low or very low. The authors concluded that “There was no evidence for the potential efficacy of recommending CL beyond standard dietary advice on T2DM”, where CL is carbohydrate last.

So in the group where you would most expect it to matter, it did not add much to eating well in the first place.

The evidence at a glance

Will eating vegetables first stop my afternoon slump?

No, and this is where the claim goes furthest past the evidence. None of the food order studies above measured energy or sleepiness. They measured glucose.

The early afternoon dip in alertness is largely built into the body clock. It shows up even in people who have had no lunch at all and have no idea what time it is. A heavy or high carbohydrate lunch makes it worse, and so does a disturbed night’s sleep. A dip in glucose after a meal has been linked to hunger and eating more later, and in a study of 1,070 people, the dip was not linked to how alert people felt. So even if eating carbs last smooths your glucose line, there is no evidence that it keeps your eyes open at two o’clock.

If the slump is your reason for looking into this, start with why you crash after lunch and the afternoon crash quiz, which looks at sleep and the shape of your day as well as what is on the plate.

So is it worth doing?

Here is how I see it.

The good. It costs nothing, it needs no special food, and starting with the salad or the vegetables is a good way to get them eaten before you are full. In short studies, it lowered the glucose rise after a meal.

The bad. The evidence is a handful of small, short studies, the first of them in people taking diabetes medication. Nothing shows it changes how you feel. Turned into a rule, it can make an ordinary dinner into a performance, and you won’t hear any of this in a thirty second video.

The verdict. Do it when it is easy, and don’t give it a second thought when it isn’t. What is on the plate matters far more than the order it goes in: vegetables, some protein and a wholegrain, roughly in the proportions of the Eatwell Guide. If a glucose sensor is part of the pitch you have seen, read whether you need a glucose monitor first. For a breakfast that holds you to lunch whichever end you start at, see breakfasts that keep you full.

If you have diabetes

The original research was done in people with type 2 diabetes on medication, so it may be more relevant to you than to anyone else reading this, and that is exactly why it is a conversation for your own diabetes team rather than a video. Speak to them before you change what or when you eat, especially if you take medication timed to meals. This post is about appetite and energy in people who do not have diabetes, and nothing in it prevents or manages diabetes.
