Gram Research analysis shows that eating vegetables and protein before carbohydrates reduces blood sugar spikes by about 54% in the first hour for trained athletes, according to a 2026 randomized trial of 14 soccer players. However, this meal order increased reported hunger and cravings for sweets and salty foods, despite lower hunger hormones, suggesting meal sequence affects athletic appetite in complex ways that warrant further investigation.
A new study looked at how the order of foods in a meal affects young soccer players’ bodies. Researchers found that when athletes ate vegetables and protein before carbohydrates (like rice or bread), their blood sugar stayed more stable and they felt less hungry for snacks afterward. However, they also craved sweet and salty foods more. This research suggests that simply changing the order of foods on your plate might help athletes manage their energy and appetite better during training and competition.
Key Statistics
A 2026 randomized controlled trial of 14 trained male soccer players found that eating carbohydrates last instead of first reduced blood sugar increases by 54% in the first hour after eating.
According to Gram Research analysis of a 2026 study, the carbohydrate-last meal pattern reduced ghrelin (hunger hormone) by approximately 14,542 units over 3 hours compared to eating carbs first, yet athletes paradoxically reported greater hunger.
A 2026 crossover trial in 14 elite soccer players showed that eating carbs last increased cravings for sweet foods by 6 millimeters on a hunger scale and salty foods by 5 millimeters, despite reducing overall hunger hormones.
Research reviewed by Gram found that in 14 trained athletes, the carbohydrate-last meal sequence raised triglyceride levels by 10.8 units over 3 hours compared to carbohydrate-first eating, though this did not affect subsequent food intake.
The Quick Take
- What they studied: Whether eating vegetables and protein before carbohydrates (instead of carbs first) changes how athletes’ bodies handle blood sugar, hunger, and cravings
- Who participated: 14 healthy, highly trained male soccer players, average age 23 years old, all in excellent physical condition
- Key finding: Eating carbs last lowered blood sugar spikes by about 54% in the first hour and reduced hunger hormone levels, but athletes reported feeling hungrier and craving sweets and salty snacks more
- What it means for you: If you’re an athlete, eating your vegetables and protein before carbs might help keep your energy more stable during the day, though you may need to manage cravings. This finding is preliminary and should be tested in larger groups before making major diet changes.
The Research Details
This was a carefully controlled experiment where 14 soccer players each ate the same breakfast twice, but in different orders. In one meal, they ate carbohydrates (bread and juice) first, followed by vegetables and protein. In the other meal, they reversed the order, vegetables and protein first, then carbs. The meals were separated by 1-2 weeks to let their bodies return to normal between tests.
The researchers measured blood sugar, insulin, and hunger hormones every 15-30 minutes for 3 hours after each meal. They also tracked what the players ate for the next 3-6 hours to see if the meal order affected how much they ate later. This crossover design (where each person does both conditions) is powerful because it eliminates differences between people, each athlete serves as their own comparison.
The study was ‘outcome assessor-blinded,’ meaning the people measuring results didn’t know which meal order the athletes had eaten. This prevents bias in how they record the data.
Most research on meal order has been done with non-athletes or people with diabetes. Athletes eat very differently, they consume lots of carbs and have different metabolic responses than regular people. This study fills that gap by testing whether meal order matters specifically for trained athletes, whose bodies process food differently.
This is a well-designed study with good controls: each athlete was their own comparison, the order of meals was randomized, and the researchers were blinded to which meal order was being tested. However, the sample size is small (only 14 people), all participants were young, healthy males, and all were soccer players. Results may not apply to female athletes, older athletes, different sports, or people with health conditions. The study only measured short-term effects (3-6 hours), so we don’t know if benefits last longer.
What the Results Show
When athletes ate carbs last instead of first, their blood sugar rose much less in the first hour, about 54% lower increase. This is important because high blood sugar spikes can lead to energy crashes. The carb-last approach also reduced ghrelin (the ‘hunger hormone’) by about 14,500 units over 3 hours, suggesting the body felt less hungry at a hormonal level.
Interestingly, despite having lower hunger hormones, the athletes actually reported feeling MORE hungry when they ate carbs last. They also craved sweet and salty foods more after the carb-last meal. This disconnect between what hormones showed and what people felt is puzzling and suggests meal order affects appetite in complex ways.
The carb-last meal also caused higher triglycerides (a type of fat in the blood) and higher GIP (a hormone that helps regulate blood sugar). Despite these changes and increased cravings, the athletes didn’t eat significantly more food in the 3-6 hours after the meal, suggesting the cravings didn’t translate into actual overeating.
The study found that eating carbs last increased GIP levels by about 1,705 units compared to eating carbs first. GIP is a hormone that helps your body respond to food, and higher levels might help with blood sugar control. The carb-last meal also raised triglycerides (blood fats) by about 10.8 units, which could be a concern if this pattern continued long-term, though one meal’s effect is minor.
Previous studies in non-athletes showed that eating vegetables and protein before carbs reduces blood sugar spikes and helps people feel fuller longer. This study confirms the blood sugar benefit works in athletes too, but adds new information: athletes experience stronger cravings with this meal order, and their hunger hormones and actual eating behavior don’t always match. This suggests athletes’ bodies may respond differently to meal order than non-athletes.
The study only included 14 young, healthy male soccer players, so results may not apply to women, older athletes, different sports, or people with health conditions. All participants were highly trained, so casual exercisers might respond differently. The study only measured effects for 3-6 hours after one meal, so we don’t know if benefits continue longer or if eating this way every day produces different results. The disconnect between lower hunger hormones and higher reported hunger is unexplained and needs more research.
The Bottom Line
For athletes: Eating vegetables and protein before carbohydrates may help stabilize blood sugar during training and competition (moderate confidence). Be aware you may experience stronger cravings for sweets and salty foods with this approach, so plan snacks accordingly. This strategy appears safe based on this study, but more research in larger groups is needed before making it a permanent dietary change. Consult with a sports nutritionist before making major diet changes.
This research is most relevant to competitive athletes, especially those in sports requiring sustained energy like soccer, basketball, or endurance sports. It may also interest people trying to manage blood sugar or reduce energy crashes. This study doesn’t apply to young children, people with eating disorders, or those with certain medical conditions without consulting a doctor first.
Blood sugar benefits appeared within the first hour of eating and lasted through the 3-hour measurement period. Hunger and cravings also appeared within hours. If you tried this meal order, you’d likely notice effects on hunger and cravings within days, though long-term benefits for athletic performance would take weeks to months to evaluate.
Frequently Asked Questions
Does eating carbs last help athletes control blood sugar?
Yes, a 2026 study of 14 soccer players found eating vegetables and protein before carbs reduced blood sugar spikes by 54% in the first hour. However, this effect was measured over just 3 hours after one meal, so longer-term benefits need more research.
Will eating carbs last make me feel less hungry?
Paradoxically, no. Although hunger hormones decreased, athletes in the study reported feeling MORE hungry and craving sweets and salty foods more when eating carbs last. This suggests meal order affects hunger in complex ways that don’t always match hormone levels.
Should I change my meal order if I’m an athlete?
This study suggests potential benefits for blood sugar control, but it’s preliminary evidence from only 14 young male soccer players. Consult a sports nutritionist before making major diet changes, as results may differ based on your sport, age, sex, and individual metabolism.
How long do the blood sugar benefits last after eating?
The 2026 study measured benefits for 3 hours after eating, showing sustained lower blood sugar during that period. Whether benefits extend beyond 3 hours or accumulate over days of eating this way remains unknown and needs further research.
Does eating carbs last affect how much athletes eat later?
No, the study found that despite increased cravings, athletes didn’t eat significantly more food in the 3-6 hours after eating carbs last compared to carbs first. Cravings didn’t translate into actual overeating in this short-term measurement.
