Let’s explore more about the 30-30-30 diet method.

What is the 30-30-30 Diet Rule?

The 30-30-30 rule was originally described by author Tim Ferriss in his book “The 4-Hour Body.” However, it went viral on TikTok thanks to Gary Brecka, a podcaster and self-described “human biologist” who discusses various ways to improve physical and mental health. Brecka’s videos, which have garnered millions of views, break down the 30-30-30 rule and its potential effects on weight loss and blood sugar control.

According to the rule, one should consume 30 grams of protein within 30 minutes of waking up and then engage in 30 minutes of low-intensity exercise. The idea behind this method is that eating a high-protein breakfast and exercising in the morning can aid in weight loss and overall health. However, it’s important to note that the 30-30-30 rule does not involve any other dietary restrictions or calorie counting.

Does the 30-30-30 Method Work?

While the 30-30-30 method has gained popularity, it’s difficult to determine its effectiveness for weight loss due to the lack of rigorous scientific studies. Tara Schmidt, lead registered dietitian at the Mayo Clinic, states that the effectiveness of any diet or fitness plan varies depending on the individual and their goals.

However, we can analyze the different steps involved in the 30-30-30 method to understand their potential benefits. Let’s explore the research behind eating a high-protein breakfast and engaging in low-intensity exercise in the morning.

Breakfast and Weight Loss

The role of breakfast in weight loss is a topic of debate among experts. While some studies suggest that eating breakfast can aid in weight loss, the evidence is rated as fair by Schmidt. The National Weight Control Registry study found that individuals who maintained long-term weight loss tended to eat breakfast every day, indicating a potential link between breakfast consumption and weight management. However, the exact reason behind this association is still unclear.

Although some claim that breakfast can boost metabolism, the evidence supporting this claim is lacking. A recent analysis found no significant difference in calorie burning between those who ate a larger breakfast and those who did not. However, Jason Machowsky, an exercise physiologist and registered dietitian, suggests that eating breakfast within a few hours of waking can be beneficial for individuals who feel more energetic and active throughout the day.

The 30-30-30 rule specifically recommends consuming 30 grams of protein for breakfast. While it may not be necessary to eat breakfast within 30 minutes of waking up, Schmidt emphasizes the benefits of including 30 grams of protein. The Institute of Medicine’s dietary reference intake recommendations state that healthy adults should consume 0.8 grams of protein per kilogram of body weight daily. This translates to approximately 54 grams of protein per day for a 150-pound adult.

Research suggests that consuming protein at breakfast can enhance satiety, blood sugar control, and insulin resistance. High-protein breakfast options include eggs, lean meats, Greek yogurt, ultra-filtered milk, nut butter, and protein shakes. Schmidt recommends adding fruits and vegetables to provide additional fiber and nutrients.

Low-Intensity Exercise for Weight Loss

The final step of the 30-30-30 method involves performing 30 minutes of low-intensity, steady-state cardiovascular exercise after breakfast. This type of exercise elevates the heart rate without causing excessive breathlessness and can be sustained for a longer duration. Examples of low-intensity exercises include brisk walking, biking, swimming, or using an elliptical machine.

The U.S. Department of Health’s physical activity guidelines recommend that adults engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity physical activity per week. While any exercise can help lower blood sugar levels, Schmidt suggests that there isn’t enough research to support the need for immediate exercise after a meal.

In TikTok videos, Brecka claims that the 30-30-30 method aids in fat burning. However, the concept of “fat-burning” is complex and depends on various factors. Lower-intensity exercise may burn a higher percentage of calories from fat, but higher-intensity exercise can lead to greater overall calorie expenditure. To achieve weight loss, it’s crucial to maintain a calorie deficit.

Morning exercise has its benefits, including increased mindfulness of eating choices throughout the day and the establishment of a consistent exercise routine. A study published in the journal Obesity found that exercising between 7 a.m. and 9 a.m. may support weight loss efforts. However, the sustainability and effectiveness of morning exercise depend on individual preferences and circumstances.

Does the 30-30-30 Rule Help with Weight Loss?

The effectiveness of the 30-30-30 method ultimately depends on an individual’s baseline activity level and existing habits. Machowsky suggests evaluating whether the 30-30-30 steps are an improvement upon current habits. If someone is not engaging in any exercise and begins incorporating 30 minutes of low-intensity cardio, it can be a positive change. However, if an individual reduces higher-intensity or longer workouts to accommodate the 30-30-30 method, they may not burn as many calories as before.

While the 30-30-30 method has gained popularity, it’s essential to remember that weight loss primarily depends on being in a calorie deficit. If the 30-30-30 method does not create this deficit, it may not lead to weight loss.

Risks of the 30-30-30 Rule

Compared to other fad diets and fitness trends, the 30-30-30 rule is relatively safe and less concerning, according to Schmidt. The core principles of consuming a high-protein breakfast and engaging in daily exercise are generally beneficial. However, these practices may not work for everyone.

Machowsky advises against force-feeding oneself breakfast if it’s not appealing or feasible in the morning. Not everyone can tolerate food early in the day, and morning workouts may not suit everyone’s preferences. It’s essential to listen to your body and make choices that work for you.

Consuming 30 grams of protein at one time is generally safe, as the recommended daily protein intake for the average adult is higher than this amount. However, individuals with chronic kidney disease or specific health conditions may need to limit their protein intake. It’s always advisable to consult a physician before making significant changes to your diet or exercise routine.

Low-intensity exercise for 30 minutes is generally safe for most individuals. However, anyone with underlying health conditions should consult their doctor before starting any new exercise program. It’s crucial to listen to your body and stop any activity that causes discomfort or pain.


The 30-30-30 diet rule has gained attention as a potential weight loss method. While it may have some benefits, such as consuming a high-protein breakfast and engaging in low-intensity exercise, its effectiveness for weight loss varies among individuals. The most important factor in weight loss is maintaining a calorie deficit. As with any diet or fitness plan, it’s essential to find an approach that is sustainable and suits your individual needs and preferences.
