Thomas DeLauer identifies key drawbacks of GLP-1 agonists like Ozempic—loss of lifestyle habits, carb preference, metabolic slowdown, muscle/bone loss, micronutrient gaps, reduced training drive, transient cardiometabolic benefits, and serious gastroparesis risk—and offers strategies to mitigate each.
2
He advises deliberately increasing calorie intake (fats/protein) for 1–2 weeks while on the drug to stall weight loss and prevent basal metabolic rate crash, logging food to ensure it’s purposeful.
3
He recommends using the Lumen device to measure real-time fat vs carb oxidation and tailor exercise timing, and emphasizes a low-carb or keto transition after stopping the drug to activate PPAR-alpha and achieve lasting metabolic flexibility.
4
For gastrointestinal motility, he suggests fasting periods instead of grazing, bitter greens and beets to stimulate bile, and close monitoring of dosage if nausea persists; he calls gastroparesis a “catastrophic” risk.

Carbohydrate elimination after Ozempic
WhatWhen coming off a GLP-1 agonist, eliminate carbohydrates and emphasize protein and healthy fats to prevent metabolic rebound and leverage increased appetite for muscle building.
WhenImmediately upon cessation of the drug.
DoseOngoing transition period.
For whomAnyone stopping GLP-1s.
WhyAppetite will return; eating more protein and fat instead of carbs prevents metabolic problems, supports muscle protein synthesis, and triggers PPAR-alpha for lasting fat oxidation flexibility.
DeLauer argues that as appetite returns, people will eat more; if they eat carbs, it causes metabolic problems. Instead, the higher appetite can be directed to protein and fats, which are muscle-sparing and less likely to be stored as fat. He cites research that low-carb intake triggers metabolic reprogramming via PPAR-alpha, leading to lasting improvements in fat oxidation. This is contrasted with Ozempic's temporary benefits. So this protocol should be started upon exiting the drug, possibly planned ahead. He also mentions that people on the drug tend to prefer carbs, so this is a deliberate shift. It builds a new lifestyle to fall back on.
Mechanism
Low carbohydrate intake combined with higher protein/fat activates PPAR-alpha nuclear receptor, reprogramming cells to oxidize fat more efficiently (metabolic flexibility); also satiety from protein helps control increased hunger without carb-driven fat storage.
When you're coming off, it really makes a lot of sense to actually just eliminate carbohydrates.
Also said
“You might as well eat more protein and maybe some healthy fats because if you start overeating the carbohydrates, that's going to be a metabolic problem.”— Justifies the carb avoidance.
“This could be hugely beneficial to just have our appetite come back, but start ramping up protein.”— Emphasizes the positive reframing.
1–2 week deliberate calorie increase on Ozempic
WhatPlan a 1–2 week period while on the drug where you deliberately increase calories (fat and protein) to stall weight loss and prevent a metabolic rate crash; log food to ensure higher intake.
WhenDuring GLP-1 treatment, periodically (as needed, perhaps every few months).
Dose1–2 weeks of increased intake.
For whomPeople on long-term GLP-1 therapy.
WhyPrevents the basal metabolic rate from dropping too low, maintaining energy flux so that when you cease the drug, you can ramp up activity without massive regain.
CaveatsMentally counterintuitive; must log food to ensure it's not accidental.
He says this is akin to reverse dieting. A low-energy flux state (eating little, moving little) is associated with illness, so the goal is to keep eating and moving high. Since Ozempic encourages low intake, you must force high intake through deliberate effort. After the 1–2 week surplus, when you stop the drug, you increase calories further via fat and protein and pair with high-intensity interval training and resistance training, not low-intensity cardio, which just increases appetite. This protocol ensures you don't crash and have a higher metabolic capacity to sustain weight loss long-term.
Mechanism
By increasing intake, you signal to the body that energy is plentiful, thereby preventing adaptive thermogenesis and keeping metabolic rate elevated (energy flux theory).
You need to take a week to two weeks and you need to actually log your food so that you eat more and stall your weight loss purposely as much as you can for a week or two so you're not crashing your metabolism.
Also said
“We want to eat more and move more. The problem is Ozimpic is encouraging us to eat less.”— Frames the rationale.
Isometric muscle preservation
WhatIf lacking energy for full resistance training, perform isometric exercises (wall sits, static flexing) to preserve muscle mass.
WhenAnytime during low-calorie GLP-1 regimen, when unable to do regular workouts.
DoseUnspecified frequency; as tolerated.
For whomThose too fatigued to sustain regular resistance training.
WhyResearch suggests isometrics preserve almost all muscle compared to bed rest; the mechanical stimulus itself (tension) is key.
DeLauer references Dr. Don Layman's hierarchy that resistance training is the number one stimulus for muscle, protein second. He cites evidence that during bed rest, isometrics preserve muscle while bed rest alone causes wasting. Even simple holds can be effective. So for someone feeling too exhausted to lift, doing wall sits or static contractions can stave off some of the muscle loss associated with rapid weight loss.
Mechanism
Muscle protein synthesis is primarily stimulated by mechanical tension, not just dietary protein; isometric contractions generate sufficient tension to signal maintenance.
When you compare bed rest to isometrics, isometrics preserve almost all their muscle. Bed rest wastess away.
Also said
“Even if you have to go do a wall sit, if you have to hold your arms like this and flex and do an isometric, there is evidence that suggests that even isometrics are key for just preserving muscle.”— Specific example.
Bitter greens and beets for bile/motility
WhatConsume bitter greens (arugula, turnip greens, beet greens, dandelion) and beets to stimulate bile production and release, aiding digestion and gastric motility.
WhenWhile on GLP-1 agonists, especially if experiencing nausea or slow digestion.
DoseRegular inclusion in meals.
For whomGLP-1 users concerned about gastroparesis.
WhyBile helps emulsify fats and promotes movement, counteracting the drug's motility-slowing effects.
CaveatsIf already with full gastroparesis, it's very hard to reverse; consult doctor for dose adjustment if nausea is persistent.
DeLauer explains gastroparesis is a serious risk. He advocates preventive measures: hydration, soluble fiber, healthy bile flow. Bitter greens are a natural way to enhance bile. This may prevent the severe slowing. However, if nausea is constant, the user should consider reducing the dose under medical supervision. He acknowledges this is a hard drawback to solve completely.
Mechanism
Bitter compounds trigger the gallbladder to contract and release stored bile, which speeds up fat digestion and intestinal movement. Beets contain betaine which also supports digestion.
Bitter greens trigger the gallbladder to squeeze and release and contract more bile, which is going to help you emulsify and break down those fats better, which is going to make it move through your system a little bit faster.
Also said
“The bitter greens and also beets themselves, betane can also help this whole process.”— Adds beets as a complement.
Fasting to increase motility
WhatInstead of eating small amounts throughout the day, have clear periods of fasting to increase gastrointestinal motility.
WhenWhile using GLP-1s.
DoseUnspecified fasting window.
For whomGLP-1 users.
WhyFasting increases motility, counteracting the slow-down from the drug.
CaveatsAfter fasting, be careful not to overeat as large meals can cause sickness; plan meals when breaking fast.
DeLauer notes that continuous grazing on Ozempic keeps digestion sluggish. By fasting, the gut gets rest and motility can increase. He suggests having defined fasting windows and then eating within them, rather than constant small bites. This might also help prevent severe gastroparesis. It's a simple behavioral modification.
Mechanism
Gut motility is enhanced during fasting periods by resetting the migrating motor complex.
Fasting actually increases motility. So maybe when you're doing ozic, it's better to have periods of time where you just go without food altogether. Make it a clear fast and then eat rather than just grazing throughout the day.
Also said
“You actually can have the chance of increasing motility a little bit by just fasting and then eating enough.”— Reinforces.
HIIT + calorie increase after cessation
WhatWhen coming off the drug, pair deliberate caloric increase (from fat/protein) with high-intensity interval training and resistance training, not low slow cardio.
WhenAfter stopping GLP-1.
DoseAs tolerated, integrate into new routine.
For whomThose transitioning off GLP-1 agonists.
WhyLow-intensity cardio can increase appetite without sufficiently boosting metabolic capacity, whereas HIIT and strength training paired with more food raises energy expenditure and builds muscle.
He explains that after cessation, many people try to maintain low calories and do low-intensity cardio, which only increases appetite and leads to weight regain. The better approach: increase calories intentionally from protein and fat, and perform high-intensity training with resistance work to create a high energy throughput. This prevents the classic crash and sets a new, more robust metabolic baseline.
Mechanism
HIIT elevates EPOC and metabolic demand, synergy with higher calories improves energy flux.
High-intensity interval training for short periods of time along with more calories, not just low slow cardio, trying to keep your calories as low as you can and you do low slow cardio and just increases your appetite.
Also said
“Be deliberate with intensity and resistance training and increase those calories.”— Concise directive.

deliberate calorie surplus to preserve metabolism
While on Ozempic, DeLauer advises intentionally eating more (fats and protein) for 1–2 weeks to stall weight loss and prevent a crash in basal metabolic rate, recording everything to ensure it’s deliberate.
Why this matters: This goes against the typical assumption that a continuous deficit is optimal; it's a proactive metabolic protection strategy rarely discussed in mainstream GLP-1 guidance.
Background
Standard advice for GLP-1 users is to maintain calorie reduction; DeLauer argues that chronic low energy intake lowers basal metabolic rate, setting up rapid weight regain after cessation.
DeLauer explains that chronic calorie restriction reduces basal metabolic rate, leading to low energy flux—eating little and moving little—which characterizes sick people, not healthy ones. The goal should be to eat more and move more. Ozempic encourages eating less, so to counteract, one must schedule a deliberate period of higher intake, specifically via fat and protein, and log food to ensure intake rises. This stalls weight loss temporarily but keeps metabolic rate from plummeting. He likens it to reverse dieting while on the drug. Upon stopping, he recommends increasing calories further via fat/protein and adding high-intensity interval training, not low-intensity steady-state cardio, because that would just increase appetite without boosting metabolic engine. The emphasis is on intensity and resistance training to build a robust energy flux.
You need to take a week to two weeks and you need to actually log your food so that you eat more and stall your weight loss purposely as much as you can for a week or two so you're not crashing your metabolism.
Also said
“What we want is to keep fluxing at a high capacity and then when you come off of it, you want to increase your calories via fat and protein, but also increase your activity via intentional and intense work.”— Explains the full arc of preserving metabolic flux and then ramping up after cessation.
carbohydrate preference on GLP-1s
GLP-1 agonists reduce appetite for fats and protein, causing users to gravitate toward carbohydrates and processed carbs, undermining metabolic health and muscle preservation.
Why this matters: This is a less-discussed behavioral side effect that explains why some users still don't improve body composition despite weight loss.
Background
While GLP-1s are known to reduce overall appetite, the specific macronutrient shift away from protein and fat is rarely highlighted in patient education.
DeLauer explains that the mechanism of GLP-1, through its digestive and gustatory effects, creates an aversion to fatty and protein-rich foods like burgers, while making simple carbs more appealing. This leads to a diet of salads with chicken and rice, or worse, processed carbs, because the person is nauseous and wants something easy. Carbohydrates don't build muscle or preserve metabolic rate, so this undermines the goal. He references large anecdotal and survey data. His workaround is either adding more protein where possible, reducing carbs, or using tools like Lumen to check if the body is oxidizing fat despite carbs. He also suggests testing ketones for a muscle-sparing effect.
A lot of times when people are on a GLP-1 receptor agonist, they prefer to eat carbs... You have a stronger aversion to fats. You don't want to eat as much fat. You actually don't want to eat as much protein either.
Also said
“Or worse, you start leaning into processed carbohydrates because that makes even more sense to you because you're kind of like, I'm hungry. I just need to eat something. Maybe you're a little nauseous and the last thing you want to eat is a juicy burger or some good protein.”— Details the real-world consequence that leads to poor dietary quality.
transient cardiometabolic improvements
A 68-week study found that upon stopping Ozempic, all cardiometabolic benefits (blood sugar, cardiovascular risk) reverted to baseline by week 120, because the underlying lifestyle hadn't changed.
Why this matters: It debunks the notion that the drug confers lasting health changes; without sustained behavioral shift, the benefits are borrowed.
Background
The Endocrine Society study provides hard evidence that the drug's protective effects are not durable after discontinuation.
DeLauer cites this study and then contrasts with research showing that a low-carb, higher-protein/fat diet can trigger PPAR-alpha, a nuclear receptor that travels to the nucleus and reprograms the cell to better oxidize fat, creating metabolic flexibility. This change can be lasting even without significant weight loss. Thus, adopting a low-carb or ketogenic approach alongside or after Ozempic can solve the problem of fading benefits. He argues that Ozempic's metabolic benefits come solely from weight loss, and when weight is regained, benefits vanish, whereas a metabolic flexibility shift via diet can provide lasting adaptation.
Ozimpic gives you metabolic benefit because you lose weight. But if you gain the weight back, you lose that metabolic benefit.
Also said
“There was a study published in exercise and sports science reviews that found that when subjects reduced carbohydrate intake and increased protein and fat, it actually triggered a metabolic change where something called PP A alpha, which is a nuclear receptor protein, a transcription factor, travels to the inside of the cell to the nucleus and reprograms the cell to be better at oxidizing fat.”— Provides the mechanistic counterpoint showing how to get durable benefits.
gastroparesis risk and motility solutions
GLP-1s can cause gastroparesis (stomach paralysis), a dire complication. Fasting, bitter greens, beets, hydration, and soluble fiber can help maintain motility.
Why this matters: This severe side effect is often downplayed; DeLauer offers practical, food-based interventions to mitigate it.
Background
Gastroparesis is a known risk of GLP-1 agonists due to slowed gastric emptying.
DeLauer calls gastroparesis the “catastrophic” drawback. He explains that once full paralysis occurs, it's hard to reverse. To prevent it, he recommends periods of clear fasting (not grazing) which actually increase motility, hydration, soluble fiber, and maintaining healthy bile flow. Bile is key for motility. He suggests bitter greens (arugula, turnip greens, beet greens, dandelion) to trigger gallbladder contraction and bile release, aiding digestion and movement. If already nauseous, the dose may need to be lowered. He acknowledges this is a hard problem to solve entirely, but these steps can help.
People can have gastroparesis. They can actually paralyze their gut because they're stopping it so much. And there are some cases where people have a hard time getting it back.
Also said
“Bitter greens trigger the gallbladder to squeeze and release and contract more bile, which is going to help you emulsify and break down those fats better, which is going to make it move through your system a little bit faster.”— Explains the mechanism behind the food advice.
low-calorie state kills training intensity
On Ozempic, low energy intake robs drive and willpower to train near failure, undermining progressive overload—a key stimulus for muscle preservation.
Why this matters: This addresses the often-overlooked psychological/physiological loop where the drug's energy deficit prevents the very training needed to retain muscle and metabolic health.
Background
Many assume people on GLP-1s can just go to the gym; DeLauer points out the practical barrier.
He explains that proximity to failure is essential for muscle building/loss prevention, but that requires enduring discomfort, which demands energy. Caloric restriction saps willpower gradually; sheer neurological willpower can last a week, then fades. So the user ends up unable to generate sufficient training intensity, leading to muscle wasting. The solution is either to raise calories deliberately (as earlier) or to find ways to strategize intensity with what little energy exists, perhaps using isometrics. Yet he acknowledges it's very hard.
In order to endure and put up with pain and things that are suffering, you need to have a certain element of willpower. And to have that willpower and drive, you need to be fueled.
Also said
“You can go off sheer neurological willpower for a little while, maybe a week, but then it's going to fall away.”— Highlights the unsustainability.

Bomar Nutrition multivitamin
Supplement
A multivitamin with an organ blend that he recommends to cover micronutrient gaps when calorie intake is low on GLP-1s.
Because GLP-1 users often eat few meals and may miss omega-3s and other micronutrients, a multivitamin is a simple safeguard. He specifically recommends ones with organ blends for their nutrient density.
Invest in a good multivitamin. Invest in one that has good compounds in it. I recommend ones that are like an organ blend. Bomar Nutrition has a good one.
A handheld device you breathe into to measure CO₂ and determine if you're oxidizing fat or carbs at that moment, with a connected coaching app. He uses it to guide training (if fat oxidation, do low-intensity cardio; if carb oxidation, do anaerobic/lifting) and to check if diet is shifting substrate usage.
DisclosureProvided a discount code (lumen.me/delaur for 20% off) indicating affiliate partnership.
DeLauer found Lumen useful for optimizing training timing and fuel substrate utilization. For GLP-1 users, it can help ensure they're in fat-burning mode and preserving muscle, and to avoid the carb-heavy path that the drug might promote. The insight can guide both diet and exercise decisions. It was built by physiologists and PhDs and includes a coaching feature.
Personal experience
I found it extremely useful for myself just in all kinds of things.
I put a link down below for something called lumen... you breathe into and it tells you whether you're oxidizing fats or utilizing carbs at that point in time.
Also said
“I breathe into it to know, hey, I'm in a more carb burning state. This makes sense for me to do more anaerobic or more lifting right now.”— Shows personal usage to dictate exercise choice.
