According to a study published in the European Journal of Clinical Nutrition, eating your food in a certain order — vegetables first, protein and fat second, and carbohydrates last — can lower your blood sugar spike after a meal by as much as 73 percent. Same food. Same number of calories. Just a different order. You can use this food order hack at your next meal.
I get what that sounds like. Not enough. It’s too good to be true.
That’s what I thought when I first read this study about six months into my own weight loss journey. I had already lost some weight by cutting back on refined carbs, but I kept getting tired in the afternoon and hitting plateaus that made me angry. Then I came across a study that shocked me.
Scientists gave participants the same meal in different orders and measured how their blood sugar levels changed. When the participants ate vegetables before carbohydrates, their glucose spike dropped by as much as 73% compared to when they ate the same foods mixed together or in the opposite order.
After reading that, I stared at my screen for a long time.
The same food. In a different way. A 73% difference in blood sugar levels.
That’s not a small change. That is a completely different way that your body reacts to the same plate of food.
Why Does the Order in Which You Eat Food Have Such a Big Effect on Your Blood Sugar?
The way it works is simple: fiber makes a physical barrier in your digestive system.
When you eat vegetables first, the fiber in them protects your gut. That layer makes it harder for the body to break down the food that comes after it. When the carbohydrates get to your digestive tract, they hit this fiber barrier instead of quickly getting into your bloodstream.
Eating protein and fat second adds another layer of protection. Both slow down the emptying of the stomach, which means that food moves out of it more slowly. This makes the glucose curve that follows even flatter.
Three things are already working against a spike by the time carbohydrates come into play:
- The barrier of fiber is there
- The protein and fat have already slowed down digestion
- You probably don’t need as many carbs because you’re already somewhat full
Studies on this mechanism indicate that the difference in glucose spikes is significant. In studies on food sequencing, participants who consumed protein and vegetables prior to carbohydrates exhibited markedly reduced insulin levels in the subsequent hour after the meal. Less insulin means less signaling for fat storage. When your body sends fewer signals to store fat, it can burn the fat it already has more easily.
How Do You Really Do It?
This is the hands-on part, and it’s really easy.
Step 1: Start With the Vegetables (About 10 to 15 Minutes)
Before you do anything else, eat all the vegetables on your plate. Not a few bites. Every one of them. This includes salads, cooked vegetables, leafy greens, broccoli, asparagus, cucumbers, and anything else on the plate.
Vegetables should take up half of your plate. A few pieces of lettuce won’t make a real fiber barrier. Volume is important here.
Don’t put the vegetables on your plate with the other food. Eat them first and keep them apart. Mixing takes away the sequencing effect.
Step 2: Add Protein and Healthy Fats Second (About 10 to 15 Minutes)
Once the vegetables are done, move on to the protein. It doesn’t matter if your protein comes from chicken, fish, beef, eggs, tofu, or something else. At this point, you can also eat healthy fats like avocado, olive oil, nuts, and cheese.
Carbohydrates have a much stronger effect on insulin than protein does. Healthy fats don’t really change the amount of insulin in your body. Eating them second means you are still slowing down digestion and making yourself feel full before the carbs come.
Step 3: Carbs Come Last (and Usually Less Than You Thought)
When you get to the carbs, two things usually happen. First, you’re already fuller than you would be if you had eaten in the usual order. Second, the glucose response to those carbs is greatly reduced because your digestive system is slowed and buffered.
From what I’ve seen, eating carbs last usually means I eat a lot less of them than I would have otherwise. Not because I was holding back. Just because I was already happy.
At this point, a reasonable amount of carbs is about the size of your fist, or half a cup to a cup of cooked grains, legumes, or starchy vegetables.
What Does This Look Like With Real Food?
At Home
If your dinner is chicken, broccoli, and brown rice, eat all of the broccoli first. Then the chicken. Then a little bit of rice, if you still want it. In my experience, the rice portion is usually much smaller than it would have been otherwise, and I don’t miss it.
In a Restaurant
Before the main course comes, eat all of your side salad or vegetable appetizer. Eat the vegetables on your plate first, then the protein, and finally the starch. You can skip the bread basket altogether or ask the server not to bring it.
At a Fast Food Place
If you have no other choice, order a side salad and eat it first. Then, eat the protein part of what you ordered and leave the bread or starch for last or skip it.
The pattern stays the same no matter where you are. First, eat fiber and vegetables. Second, protein and fat. Last are carbohydrates.
What Happens When You Stop Mixing Things Up?
This is where people often say no. People today eat by scooping up forkfuls of everything at once, like rice, vegetables, and chicken. It seems normal.
But that mixed approach completely gets rid of the protective sequencing effect. The fiber, protein, fat, and carbs all get to the gut at about the same time. This means that there is no fiber barrier, digestion doesn’t slow down, and the glucose spike goes up faster and higher.
At first, it feels strange to eat in order. It becomes second nature in a week or two. The part you notice the most is that your energy changes after you eat. The afternoon crash that used to happen after a lunch full of carbs seems to go away. The desire for something sweet after dinner usually goes down or goes away.
That is not a coincidence. The insulin spike that happens after fast glucose absorption is mostly what causes the crash and the cravings. Lessening the spike will also lessen the crash and the craving that comes with it.
Mistakes That Make the Effect Go Away
Putting Different Kinds of Food on the Same Plate
If you mix vegetables into pasta or rice, the order of the sequence is lost. You should eat foods in order, one at a time.
Eating Too Fast
It takes time for the protective effect to work. It takes about 10 to 15 minutes for each stage of digestion to work. Eating the whole meal in five minutes takes away the benefit.
Not Getting Enough Vegetables in the First Stage
A little bit of lettuce on top is not a barrier to fiber. Try to get a big serving, at least half of the plate.
Eating Carbs First When You’re Hungry
If you’re really hungry and the bread basket comes before anything else, eating it makes everything else go away. Ordering a vegetable appetizer ahead of time stops this from happening.
Frequently Asked Questions
Will this work with all types of carbs?
Studies indicate that the food order effect is applicable to both refined and whole-grain carbohydrates, although the baseline glucose response varies between the two. Eating whole-grain carbs last makes your blood sugar rise less than eating refined carbs last. The sequencing adds extra protection to the quality of the carbohydrates.
Do you have to do this for every meal?
No. This is one of the useful things about this hack. You don’t have to perfectly restructure every meal. Starting with this method at your biggest meal of the day, which is usually dinner, is already helpful. Most people naturally use it on other meals as well as it becomes a habit.
What if the restaurant doesn’t have a vegetable appetizer?
Get a side salad to start. A lot of restaurants have one. Finish it before the main course gets there. This is the restaurant version of the first stage, and it has the same effect.
Will this method help me lose weight even if I don’t change what I eat?
Studies indicate that consistently mitigating postprandial glucose spikes generally leads to a decrease in overall insulin exposure over time. Having less insulin in the body is linked to better fat burning. In my experience, many people see changes in their weight just from ordering food. However, combining it with other habits that lower insulin levels makes the results much stronger.
Is this the only thing that needs to change to fix insulin resistance?
No. Changing the order of my meals is one of seven practical ways I lowered my insulin levels and lost 80 pounds in four years. It is the easiest to start with because you don’t have to plan meals, eat new foods, or follow any dietary rules. Start with this habit because it works right away and helps the other changes happen faster.
The Bottom Line
It doesn’t cost anything, doesn’t need any new ingredients, and doesn’t take any extra time to change the order in which you eat your food. The research that went into it is good. People know a lot about how the mechanism works. And the practical experience of putting it into practice, for me and for the readers of my book, always shows the same pattern: less hunger after meals, fewer cravings, more stable energy, and better metabolic health over time.
You don’t have to change what you eat for your next meal. You just need to change the order.
Give it a shot tonight. First, eat your vegetables. Second, protein and fat. Carbs come last.
