Why Eating More Carbs Might Be the Fix for Your Bloating, Not the Cause
If you lift, deal with chronic bloating, and have decided that carbs are the enemy…I want to change that.
Let me start by affirming that I understand how you got there. First of all, carbs have been demonized by diet culture, so we’re all under the impression that they will make us fat, bloated, and puffy. So you cut carbs, and maybe the bloating eased up for a while so the math felt obvious: fewer carbs, less bloating. But that short-term relief is hiding a longer-term problem. For most women I work with, chronic carb restriction makes the gut more reactive, more inflamed, and more dependent on an ever-shrinking list of "safe" foods.
Carbohydrates aren't causing your bloating, but they may be revealing some issues related to your gut and digestion that need attention. And in the meantime, they're doing structural work your body genuinely can't do without.
Let me walk you through why carbs are essential, especially for women who strength train, and then I'll give you a practical target to aim for.
Your gut bacteria literally eat carbs
The fiber and resistant starch in carbohydrates are the one thing your own digestive enzymes can't break down, and that’s a good thing. They travel to your colon intact and become fuel for your gut bacteria, which ferment them into short-chain fatty acids like butyrate.
Butyrate is the preferred energy source for the cells lining your colon, the same cells responsible for keeping your gut barrier intact. When you starve your gut of fermentable carbs, you're starving the cells that protect you. Over time, low-fiber intake has even been shown to push certain bacteria into eating away at your protective mucus layer instead, because you've stopped feeding them what they actually want.
So the irony is that the restriction you adopted to calm your gut can actually degrade the very environment a healthy gut depends on.
Carbs keep your metabolism (and thyroid) running
If you've been eating clean, training hard, and still constantly feel tired and are plateauing in your training, under-fueling carbs is one of the most common hidden culprits.
Low carbohydrate availability downregulates the conversion of your thyroid hormone T4 into its active form, T3. That's the form that actually drives your metabolic rate. So you can have lab values that look "fine" and still feel like your body is running at half speed.
Carbs also refill muscle glycogen, which is what powers your lifts and your recovery between them. Chronically depleted glycogen signals to your body that there is low energy availability, which is a stressor with downstream consequences for everything from your menstrual cycle to your sleep.
Carbs help regulate your stress response
Your blood sugar and your cortisol are tightly linked. When blood sugar drops, cortisol rises to mobilize stored energy. This is a normal and essential feedback loop. But when you chronically under-eat carbs, you keep that feedback loop engaged, and your body interprets low carb availability as an ongoing stressor.
For women especially, that sustained stress signal causes strain on your sex hormones, your thyroid, and your sleep. It's often the hidden reason behind the "I do everything right but my hormones are a mess" frustration.
Carbs also support your mood and sleep directly. Eating carbohydrate helps tryptophan reach your brain, which is the precursor to serotonin and melatonin. This is the real physiology behind why a modest evening carb portion can blunt your cortisol response and help you fall asleep, rather than the "no carbs after 6pm" rule you've probably heard.
So why do carbs seem to cause bloating?
Because the same fermentable carbs that build a healthy gut can produce gas and distension when they're fermented in the wrong place or by the wrong bacteria. That's what's happening with conditions like SIBO, or when your microbial community is out of balance. When bloating shows up alongside carbs, this is a clear sign that your gut needs attention.
This is why a low-FODMAP diet or reduced-carb approach can help you feel better quickly. And it's also why it's meant to be a temporary, diagnostic tool, not a long-term diet. If you stay in restriction too long then you will starve your beneficial bacteria, lower your microbial diversity, and end up tolerating fewer and fewer foods. Clients come to me convinced they're "intolerant to everything," when really their gut has just been under-fed into fragility.
The actual path forward is the opposite of restriction: identify and address the root causes, such as poor digestive function, and then reintroduce carbohydrates gradually to rebuild both your tolerance and your microbial diversity.
A practical target: aim for roughly 50–60g of carbs per meal
If you're an active woman who lifts, a good anchor to build toward is about 50 to 60 grams of carbohydrate per meal. Across three meals, that lands you in a moderate, well-fueled range, which is enough to support your training, your thyroid, your stress response, and your gut, without being extreme in either direction.
Think of this as a target to move towards rather than a goal you need to hit immediately. If you're currently very low-carb or actively symptomatic, ramping straight to 60g of beans and cabbage will not feel good. Start with gentle, well-tolerated starches and build up as your gut heals.
Here's roughly what 50–60g looks like with gut-friendly choices:
About 1¼ cups of cooked white rice (white rice is naturally low-FODMAP and easy on most guts)
One large sweet potato, or a large white potato
A cup of cooked oats with a piece of fruit
A cup of cooked quinoa plus a small banana
Two slices of sourdough with a side of berries
Notice these lean toward simpler, easier-to-digest starches: rice, potatoes, oats, sweet potato, sourdough. As your gut gets stronger, you widen the variety, because remember: diversity of plant carbs is what builds a diverse, resilient microbiome.
The bottom line
Bloating from carbs is a signal to investigate. Your body needs carbohydrates to fuel your training, protect your gut lining, keep your metabolism and hormones humming, and regulate your stress. The goal is to fix the gut terrain underneath so you can actually eat them again.
If you've been stuck in the restrict-react-restrict cycle, you need to find out what is driving this response in your gut. That's exactly where The Bloat Breakthrough Method comes in.
