What Is the 30-30-30 Rule? Nutritionists Break It Down
When it comes to fitness trends, there’s plenty of advice to sort through out there to help see you through your journey. Unfortunately, it can be hard to tell which information is legitimate and what’s not worth your time. The 30-30-30 rule is getting plenty of buzz on TikTok, raising a lot of questions about whether there’s something to this.
The 30-30-30 rule first popped up in Timothy Ferriss’s bestselling book “The 4-Hour Body.” But this method really took off after biologist Gary Brecka started promoting it on TikTok.
According to Brecka, following the 30-30-30 rule (sometimes referred to as the 30-30-30 method) can help you manage your blood sugar, lose weight, and have more energy than other eating plans.
Of course, it’s understandable to be wary of anything promoted on TikTok, especially when it comes to health and fitness advice. But nutritionists say there’s something to this method. Here’s what the 30-30-30 rule involves, plus risks and benefits to be aware of.
What Is the 30-30-30 Rule?
The 30-30-30 rule is simple. It involves eating 30 grams of protein within the first 30 minutes after you wake up, which is then followed by 30 minutes of exercise.
You can eat whatever else you want with your breakfast, but the 30 grams of protein is key. The exercise part of this plan is very specific: the 30-30-30 rule recommends that you do steady-state cardiovascular exercise, which means low-intensity cardio that raises your heart rate a little but keeps it at or under 135 beats per minute. That includes doing things like cycling, walking, or jogging.
Nutritionists say there’s something to the concept of the 30-30-30 rule. “I love that this rule is encouraging people to get daily exercise and have a significant amount of protein in the morning,” says Christy Brissette, RD, founder of 80 Twenty Nutrition in Laguna Beach, CA.
“Getting protein in the morning is good,” agrees Scott Keatley, RD, co-owner of Keatley Medical Nutrition Therapy. “Your body before exercise is generally able to absorb about 20 grams in a sitting. After exercise, it can increase significantly.”
But to Keatley, the specific recommendations seem a bit arbitrary. Protein and carbs have about the same caloric value, he says. “Why not have 15 grams of both 15 minutes after waking up and exercising for 15 minutes?” Brissette agrees that the specifics around timing “don’t make sense.”
What Are the Benefits of 30-30-30?
Despite the arbitrary recommendations, there are “solid benefits” to following this eating plan, says Karen Ansel, RDN, author of “Healthy in a Hurry: Simple, Wholesome Recipes For Every Meal of the Day.”
“Most of us skimp on protein at breakfast, so the plan can be a helpful way to squeeze in protein earlier in the day, which can help with [feeling full],” Ansel says. “And who can’t benefit from some exercise first thing in the morning?”
Protein helps with feelings of fullness, but it generally is best when you combine it with fat and carbohydrates as well, Keatley says. “You will have a pool of amino acids — what protein breaks down into — available when you’re done working out, which can help build muscle and increase your metabolic rate,” he says.
The current international recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram of body weight, regardless of age. That means that a 150-pound adult should aim to get about 55.5 grams of protein a day. With the 30-30-30 rule, you’ll be front-loading your protein intake at the start of your day.
There is some data to support the general idea of the 30-30-30 rule. Research has found that going on a high-protein diet that includes cardiovascular exercise can help people lose weight and improve their blood sugar control, although it doesn’t specify timing of workouts and eating.
But Brissette says it’s helpful to get in good nutrition and movement early in your day. “Many clients come to me with low energy and overeating later in the day because they fast all morning,” she says. “Having breakfast and 30 grams of protein can help them to feel less hungry later in the day and supports more stable energy levels.”
What Are the Risks of 30-30-30?
People’s protein needs vary, and not everyone needs or can absorb 30 grams of protein in one sitting, Keatley says.
Some people can also get a stomachache if they have a lot of protein and then work out right away, Brissette says. “When you eat, your body sends blood to your stomach to help with digestion,” she explains. “If you’re exercising at that time, the blood will move to your working muscles instead, making digestion happen more slowly. This could lead to bloating or stomach pain.”
The 30-30-30 rule also may not be a good fit for people who have to limit protein because of health conditions like chronic kidney disease, Ansel says.
The source of the protein matters, too. “Many high-protein breakfast ingredients, such as cheese and sausage, are heavy in saturated fat, which is problematic for heart health,” Ansel says.
While Keatley says the overall risks of following this eating method are minimal, he points out that it could spiral into disordered eating if people are too rigid about following the rule.
Can the 30-30-30 Rule Help You Lose Weight?
It’s important to say this: your weight is something that’s between you and your doctor, and you should never feel outside pressure to drop pounds beyond personal reasons or health gains. Unfortunately, weight-loss hacks often promise fast results, which is inherently unhealthy. (Nutritionists and doctors generally recommend losing weight at a slow and steady pace for lasting results.)
“The concept of fast weight loss in and of itself is concerning,” Ansel says. “Often, when people are trying to lose weight, those pounds have crept up over the years, so it’s unrealistic to think they will melt right off. That’s not the way the body works, and any kind of severe restriction to try to drop pounds quickly is unlikely to be successful and might even backfire because of rebound hunger and muscle loss.”
Brissette also recommends being wary of TikTok weight-loss tricks. “You need to do what’s best for you and your unique body,” she says. “Many of my clients come to me with damaged metabolisms and are completely confused about food after years of following what diet culture has dictated. We need to learn to work with our bodies rather than trying to ‘trick’ them.”
There are many different healthy eating plans out there, and finding what’s best for your body — and your overall health — is much more important than whether it helps you to lose weight.
Should You Try the 30-30-30 Rule?
If you’re interested in trying the 30-30-30 rule, nutritionists say the risks are relatively low. “If getting up and getting at your day right away works for you, there is little harm in giving it a try,” Keatley says. Brissette agrees. “If you’re someone who thrives with consistency, getting 30 minutes of exercise each morning could be a great routine for you,” she says. Brissette also suggests waiting an hour after eating before you start exercising or doing your morning cardio fasted so you don’t end up with a stomachache. But if weight loss is your primary goal, every body is different, and no plan can guarantee you’ll lose weight. If you have concerns about your health, it’s best to consult your healthcare provider to figure out what’s best for your body.

22 Trainer-Approved Bodyweight Exercises That Actually Build Muscle
Sorry to break it to you: Lack of equipment isn’t a surefire excuse to skip your workout. When you’re on the road or too busy to make it to the gym, bodyweight exercises are the always-ready tool you can turn to—and they might even challenge you more than your typical weighted workouts.
“Don’t underestimate the impact of bodyweight workouts because you will be quickly humbled,” says Kim Perry, CPT, a certified personal trainer and pregnancy coach. Bodyweight exercises are typically compound movements, meaning they activate more than one muscle group at a time. As a result, a bodyweight workout can help improve your balance, core strength, cardio, mobility, and flexibility, Perry says.
Plus, bodyweight exercises are especially great for those who are just starting off their fitness journey, says Claudette Sariya, CPT, founding instructor of SOLE Fitness. Nailing an exercise with only your bodyweight first allows you to really understand the fundamentals of a movement before loading up the weight.
Meet the experts: Kim Perry, CPT, is a certified personal trainer and pregnancy coach. Claudette Sariya, CPT, is the founding instructor at SOLE Fitness and a coach at LifeTime.
Ready to break a sweat using only your bod? Here are the 50 best bodyweight exercises to build strength, muscle, and boost your heart health, according to Perry and Sariya.
Instructions: Choose five to six moves that target the area of the body you want to hit. For a full body experience, select two upper body exercises, two lower body exercises, and two core exercises. Perform each move for 40 seconds, then rest for 20 seconds. After one round, rest for 60 seconds, then repeat two or three more rounds.
1. Hollow Body Hold
Movement pattern: Core
Why it rocks: The hollow body hold is even more challenging than a plank (trust us), and requires full-body activation. Pro tip: Press your back into the floor and squeeze your core while doing this move. If you feel your lower back is rising off the floor, bend your knees to 90 degrees, says Sariya.
How to:
- Start lying on back with with arms extended overhead on floor and legs straight resting on mat.
- At the same time, and with control, lift arms, head, shoulder blades, and legs a few inches off the floor.
- Hold the elevated position, ensuring your low back is still glued to the ground.
2. Plank
Movement pattern: Core
Why it rocks: Planks are a great way to build total body strength. They’re a type of isometric hold, which takes a lot of effort and builds both stamina and endurance. Plus, they can easily be modified by planking on your knees or elevating your hands until you can do them all-out.
How to:
- Start on all fours with shins and palms flat on mat.
- Step back onto the on balls of your feet, creating a straight line from heels through the top of your head. Keep your gaze to the floor.
- Squeeze your glutes and abs to keep hips inline with your shoulders. Hold here as long as you can.
3. Bird Dog
Movement pattern: Core
Why it rocks: This is a great move to practice coordination, and builds core stability and balance.
How to:
- Start on all fours with wrists directly under shoulders and knees under hips. Keep back flat, core engaged, and a slight bend in elbows.
- Extend left arm out in front at shoulder height and right leg straight behind at hip height.
- Bend leg and arm and bring to midline under torso until elbow and knee touch. That’s 1 rep. Alternate sides.
4. Reverse Crunch
Movement pattern: Core
Why it rocks: This move builds strength and control through your core abs. Make sure you’re using your lower abs—and not momentum—to perform this movement. If you’re struggling, imagine you’re pushing your heels to the ceiling, Sariya says.
How to:
- Start lying on back with arms by sides and feet lifted off the ground, legs extended, and toes pointed.
- Squeeze your core to pull your hips off the ground. Do your best to push your toes up towards the ceiling instead of back towards your head.
- Slowly return to start. That’s 1 rep.
5. Russian Twist
Movement pattern: Core
Why it rocks: This move builds rotational strength. Make sure you have the proper form when doing this oblique-working move: Puff out your chest and keep a long line from your tailbone to your shoulder.
How to:
- Start seated with upper body leaned back until abs are engaged, legs lifted and bent, arms bent, hands clasped, and elbows wide. For an extra challenge, lift heels up off the floor.
- Rotate torso to right side so that right elbow is hovering off mat.
- Keeping lower body still throughout, rotate the upper body to the left side. That’s 1 rep.
6. Inchworm
Movement pattern: Core
Why it rocks: This move fires up both your core and upper body, making it a great warmup move for your upper body days.
How to:
- Start standing with feet hips-width apart.
- Hinge at hips and lower down until hands reach the ground, focusing on core activation and spine alignment, keeping legs as straight as possible.
- Crawl forward lifting one hand at a time with legs straight and hips lifted until in a high plank. Try to keep hips as square to the ground as you can throughout the move.
- Walk hands one by one back to feet.
- Reverse motion to return to standing tall. That’s 1 rep.
7. Superman Arm Extension
Movement pattern: Upper Body
Why it rocks: This is a great move for people who want to strengthen their posterior chain (or all the muscles on the back side of your body!). It can even help improve posture, says Sariya.
How to:
- Start lying facedown on a mat, legs extended, elbows tucked at sides.
- Squeeze glutes to lift legs and extend arms overhead simultaneously, pulling thighs and chest off the floor.
- Pause, then lower legs and bend arms to sides to return to starting position. That’s 1 rep.
8. Triceps Dip
Movement Pattern: Upper Body
Why it rocks: This move isolates the triceps. Pro tip: Make sure your hands are right outside your hips and your elbows are pointing behind you in order to really target the back of your arms. To make it more challenging, straighten out your legs.
How to:
- Sit in a chair (or on a box/step) and grip the front edges with hands.
- Scoot butt forward until it’s hovering just off the seat and legs form a 90-degree angle and straighten arms.
- Lower body down until biceps are parallel to floor.
- Engage triceps to press back to start. That’s 1 rep.
9. Superwoman Isometric Hold
Movement Pattern: Upper Body
Why it rocks: This move works the back muscles that stabilize and support your spine, making everyday movement easier, says Sariya.
How to:
- Lie facedown on the mat, with arms and legs stretched out.
- Squeeze glutes and lift torso and legs up as far as you can. Imagine reaching out with arms and legs.
- Pause at the top and hold.
10. Incline Pushup
Movement Pattern: Upper Body
Why it rocks: This is a great move for people working their way up to a flat pushup.
How to:
- Start in an incline plank position with hands on a chair, bench, or step and feet on floor with head to heels aligned.
- Lower down, with elbows pointing 45-degrees away from body, until arms bend to 90-degrees.
- Press back up keeping body in a straight line. That’s 1 rep.
11. Pushup To Plank Row
Movement Pattern: Upper Body
Why it rocks: This exercise targets your chest and back at the same time. Once you get comfortable with the move, add a resistance band around your hands for a little more back challenge. Or, you can also pop into a high plank position for a full pushup.
How to:
- Start in a modified plank position, knees on ground, wrists under shoulders. Maintain a long spine with knees to head aligned.
- Lower into a pushup so chest hovers just above the floor, and elbows are close to sides.
- Push up from ground to return to modified plank position, then drive right elbow toward sky, performing a row.
- Return right hand to ground.
- Repeat row with left arm.
- Return left hand to ground. That’s 1 rep.
12. Air Squat
Movement Pattern: Lower Body
Why it rocks: The squat is one of the gold standard lower body exercises, and doing it with just your bodyweight is a great way to prime the move before adding load. Plus, you can incorporate it into a dynamic warm up to wake up your quads and glutes.
How to:
- Start standing with feet shoulder-width apart and arms at sides.
- Bend knees, sit hips back, and lower butt down until thighs are parallel with the floor. Bring arms forward and keep the torso upright.
- Rise back up to start, squeezing glutes at the top until your hips are just under your shoulders. That’s 1 rep.
13. Forward Lunge
Movement Pattern: Lower Body
Why it rocks: This move is great for core stability, balance, and building quad and glute strength.
How to:
- Start standing at the back of the mat with feet under hips.
- Take a large step forward with right leg, and lower down until thigh is parallel with the floor and both legs bend to 90 degrees. (Bring left hand forward and right arm back for help with balance.)
- Stand up and step right foot back to meet left.
- Repeat with left leg. That’s 1 rep.
14. Alternating Lateral Lunge
Movement Pattern: Lower Body
Why it rocks: This move builds unilateral (single leg strength) in your glutes and quads—important for fixing strength discrepancies. Pro tip: Make sure your chest stays lifted, so you can drive all your weight into your heel for maximum effectiveness. Be sure to place your toes on the same line.
How to:
- Stand with feet wider than hip-width apart.
- Bend right knee and push hips back and lower as deep as you can, aiming for at least a 90-degree bend in the knee. The left leg should be extended.
- Drive through right heel to return back to start.
- Repeat on left side. That’s 1 rep.
15. Curtsy Lunge
Movement Pattern: Lower Body
Why it rocks: This move works your glutes, and Sariya loves to add it to a superset because it’s easy to transition to from either deadlifts or squats. Pro tip: Make sure your knees are tracking toward your toes and keep your torso upright and hips and shoulders as square as possible.
How to:
- Stand with feet hip-width apart and arms at sides.
- Take a step back with left leg, crossing it behind right. Bend knees and lower hips until right thigh is nearly parallel to the floor.
- Return to start.
- Take a step back with right leg, crossing it behind left. Bend knees and lower hips until left thigh is nearly parallel to the floor. That’s 1 rep.
16. Fire Hydrant
Movement Pattern: Lower Body
Why it rocks: This is a great move for strengthening your glutes. Pro tip: Once you’ve mastered this move, add a resistance band to up the ante.
How to:
- Start on all fours with wrists stacked directly under shoulders and knees over hips.
- Draw belly button to spine and, keeping back flat, lift the right knee out to the side so it is in line with the right hip.
- Lower with control. That’s 1 rep.
- After 20 seconds, switch to the other side and repeat.
17. Glute Bridge
Movement Pattern: Lower Body
Why it rocks: Glute bridges will give you a sculpted booty, says Sariya. They also work your hamstrings.
How to:
- Lie on back with feet flat against the floor and knees bent, arms at sides.
- Squeeze glutes and lift hips off the floor until your body forms a straight line from knees to shoulders.
- Pause at the top, then lower back down to starting position. That’s 1 rep.
18. Glute Kickback
Movement Pattern: Lower Body
Why it rocks: This move challenges both your core and your glutes. Pro tip: As you kick your leg back, make sure your hips are pointing down toward the floor, says Sariya.
How to:
- Start on hands and knees, with knees under hips and hands under shoulders.
- While keeping your abs tight, contract the glutes slowly, and kick the right leg back until it’s straight.
- At full extension, squeeze the glutes for an extra second. Carefully bring it back down. That’s 1 rep.
- Switch sides and repeat.
19. Jumping Jacks
Movement pattern: Cardio/Agility
Why it rocks: This move is great for getting the blood flowing and upping your heart rate. You can also use it as part of a warm up.
How to:
- Start standing with feet together and arms at sides.
- Then, simultaneously raise arms out and overhead while jumping feet out wide past shoulders.
- Without pausing, quickly reverse the movement jumping back to narrow stance and swinging arms to sides. That’s 1 rep.
20. Jump Squat
Movement pattern: Cardio/Agility
Why it rocks: Jump squats help you build power in your lower body, and they’re a great way to end a leg day with your heart rate up, says Sariya.
How to:
- Stand with feet hip-width apart, toes slightly turned out, and arms by sides.
- Bend knees and sink hips to lower into a squat, then press through feet to explosively jump as high as you can into the air.
- Land softly on the balls of feet and immediately lower into next squat. That’s 1 rep.
21. High Knees
Movement pattern: Cardio/Agility
Why it rocks: High knees are a great warm up for quads, hip flexors, and calves, especially before a run—or a great addition to a cardio day.
How to:
- Start standing on the mat with arms bent at 90-degrees, elbows close to sides, and hands at hip height in front of body.
- Bend right leg and lift right knee up to tap palm.
- Return the right knee to the floor and quickly repeat on the left side. Stay up on balls of feet throughout movement. That’s 1 rep.
22. Knee Drive
Movement pattern: Cardio/Agility
Why it rocks: A knee drive gets your heart rate up and is good for the core.
How to:
- Start standing with feet under hips.
- Step right foot a couple feet behind left foot.
- Bend back knee and drive it forward and up as high as you can. At the same time, swing arms with the opposite leg, like you’re running.
- That’s 1 rep. Complete on the opposite side.

Social Fitness: Why Independent Living Communities Are Vital for Healthy Aging
Fitness
Alexandra Daddario, 40, relies on this underrated crunch upgrade for strong abs – here’s how to do it properly
From enduring some serious physical prep for Baywatch to working consistently with elite trainer Patrick Murphy, Alexanda Daddario’s dedication to fitness is well-documented. She often shares insights on social media, and in a recent Instagram post, the White Lotus star gave an insight into how she trains her core with one powerhouse movement: the reverse crunch into shoulder stand.
Why is it so good? Most traditional ab exercises require repetitive spinal flexion – the process of pulling your chest down toward your knees, like in a standard crunch. This isolates only the upper section of your abs, and for women who spend hours sitting at a desk, it can reinforce a slouched, rounded posture.
Daddario’s movement flips the mechanics entirely since you actively curl your pelvis up toward your chest. In doing so, you target not only your upper abs, but the lower portion and your obliques (the sides) simultaneously, all while keeping your chest open and your neck unstrained. This translates into a much stronger core, better posture and crucial lower back protection. Research also shows that a controlled posterior tilt – the lower-body curl that initiates Daddario’s move – recruits a significantly higher percentage of deep core muscle fibres than traditional crunches.
Daddario then drives her hips directly up into a vertical shoulder stand. This completely removes momentum from the equation (meaning you can’t “cheat”) and forces your abs – particularly your obliques – to balance your body and prevent you from tipping sideways.
She then takes it one step further into a Pilates plow position with her legs overhead, before reversing the movement and, again, using her abs to control the lowering of her entire lower body as she slowly unrolls her spine down onto the mat. The plow portion is optional (and super advanced); the slow, controlled, lowering phase, which happens whether you move into plow or not, is where the magic happens, challenging your core through both lifting and resisting gravity. Inspired? Here’s exactly how to do the move with good form, and how many reps and sets to aim for.
How to do a reverse crunch into shoulder stand
- Lie on your back (either on a mat, or on a reformer Pilates machine, like Daddario, with your arms anchored tightly to the floor.
- Engage your core to curl your knees toward your chest, then fluidly press your feet straight up toward the ceiling, lifting your hips and lower back off the floor.
- Slowly lower down, one vertebra at a time. Aim for 3 sets of 6-8 controlled reps.
Optional progression:
- As you reach shoulder stand with your legs extended to the ceiling, slowly start to lower your toes toward the floor over your head. Your weight should rest entirely on your shoulders and upper back – not your neck.
- Keeping your legs straight, use your core to extend them straight back up to the ceiling, then control the descent by rolling your spine down one vertebra at a time, with your legs remaining straight.
