If you feel like every time you eat carbs you blow up, retain a bunch of water, or have trouble losing body fat… it’s not that carbs are the problem.
It’s likely that your body isn’t handling them well right now, meaning your carbohydrate metabolism is off.
Importance of improving carb metabolism:
- Better body composition: carb-tolerant individuals store less as fat and direct more carbs toward muscle glycogen and training performance.
- More stable energy & focus: poor carb metabolism leads to post-meal crashes, brain fog, and reactive hunger; good carb handling gives smooth, steady output.
- Better training performance & muscle gain:carbohydrates are your primary fuel for strength and hypertrophy work — without good carb metabolism, performance flatlines.
- Improved hormonal & metabolic health: better carb use = lower insulin resistance, better blood sugar stability, and lower long-term risk of metabolic disease.
- More flexibility with food: the better your body handles carbs, the more freedom you have to include foods you enjoy without bloating, fatigue, or fat gain.
Here are some things we can work on to improve that:
→ Build Muscle
Muscle is your body’s biggest glucose sink.
More muscle = more places to put carbs.
You don’t need to be jacked to benefit, but you do need to intentionally build it.
It takes effort, and most people have way less muscle than they think.
Even if fat loss is your goal, building muscle can support it.
In fact, one study showed that increasing muscle mass led to a reduction in body fat over time.
If carbs aren’t sitting well with you, muscle might be the missing piece.
(And no, you don’t have to gain weight to build muscle.)
→ Post-meal movement –
A short walk or some light movement after meals can significantly improve blood sugar management.
This can also help with digestion + it gets you more movement in your day.
Meal → Walk = Better blood sugar control
→ Build your cardiovascular system.
Add some conditioning, minimum of 2x per week.
Start with low to medium intensity.
→ Lower resting heart rate + improve HRV.
A high RHR or low HRV usually means your body’s in more of a stressed (sympathetic) state.
This impacts how well you handle carbs, studies show low HRV is linked to lower insulin sensitivity.
This means moderating your training intensity/volume + focusing on lowering stress load on your body and dialing in overall recovery.
→ Get leaner (to a healthy range).
You don’t need to be shredded, but getting to a leaner body fat % will help.
~10–20% for men and ~20–30% for women is a solid target.
Yes, that might mean lower carbs for a bit to get there.
→ Spend time in a lower carb/lower energy state every so often.
You don’t need to (and shouldn’t) be low carb or in a deficit year-round.
But spending intentional time in a lower energy and/or carb state can improve how your body uses fuel long-term.
→ Time your carbs smarter.
Eat more carbs around workouts and earlier in the day.
Your body’s less efficient at processing carbs late at night.
→ Dial in your circadian rhythm + deep sleep.
Get morning sunlight, limit blue light at night, and stick to a consistent sleep-wake schedule.
→ Include higher intensity intervals 1x/week.
Hard intervals can help improve glucose uptake and carb tolerance.
→ Improve your carb quality.
Choose slower-digesting, fiber-rich carbs like potatoes, sweet potatoes, oats, lentils, beans, berries, and fruit.
Cut back on ultra-processed stuff where you can.
→ Bonus: Magnesium supplementation
Most people don’t get enough magnesium, and it can play a role in carb metabolism.
It’s one of the foundational supplements I include inside my coaching.
In one study, magnesium supplementation improved fasting glucose, insulin levels, and markers of insulin sensitivity.
And that’s just one of the many benefits.
A few extra thoughts:
• The menstrual cycle can impact how your body handles carbs. In the luteal phase, you may need to pay closer attention to these strategies.
• Eating carbs and gaining a pound or two from one day to the next doesn’t mean you don’t tolerate them. It’s usually just water and glycogen.
