Andrew Huberman, a professor of neurobiology and ophthalmology at Stanford University, has presented various science-backed strategies for optimizing fat loss. His protocols encompass exercise, intermittent fasting, and other lifestyle adjustments, all designed to leverage the body's natural mechanisms for burning fat. It's important to remember that the information provided by Dr. Huberman and the Huberman Lab Podcast is not medical advice and should not be used as a replacement for it.
Exercise Strategies for Fat Loss
High-Intensity Training and Adrenaline
Huberman emphasizes the importance of high-intensity training to boost adrenaline release, a key trigger for fat oxidation. To optimize fat loss, he recommends a training protocol that involves high-intensity training followed by low-intensity activities, ideally while fasted.
Variety in Training
For sustained fat loss, combining different types of training can be beneficial. This includes:
- High-Intensity Interval Training (HIIT): Short bursts of intense exercise followed by brief recovery periods.
- Sprint Interval Training (SIT): Similar to HIIT, but with maximal effort sprints.
- Moderate-Intensity Continuous Training (MICT): Sustained aerobic activity at a moderate intensity.
Exercise Timing and Fasting
Huberman also examines the impact of exercise intensity and fasted workouts on fat burning. Performing high-intensity exercise in a fasted state can further enhance adrenaline release and fat oxidation.
The Role of Non-Exercise Activity
Non-exercise movements like fidgeting and shivering trigger adrenaline to boost fat metabolism.

Intermittent Fasting Techniques
In a YouTube segment from one of his laboratory’s podcasts, Dr. Huberman describes how prolonging the hours without eating after waking up can help one capitalize on the physiological benefits, like a propensity for fat burning, from a hormonally-regulated fasted state.
Huberman says that anyone interested in using intermittent fasting to burn body fat can choose from a few different dietary schedules like going 16 hours per day without eating or eating regularly one day and then eating very few calories the next.
Intermittent fasting can be done with various eating schedules. Sixteen-hour restricted feeding involves eating only during an eight-hour window of elevated physical activity, while 24 and 36+-hour fasting encompasses fasting for these periods whenever possible. Moreover, alternate day fasting entails only eating every other day. Eating very few calories every other day is another intermittent fasting method. Eating enough calories to maintain normal metabolism and then fasting for two days can also be done, and another technique entails eating few calories (300 to 500 calories) consistently.
Here's a breakdown of various intermittent fasting techniques discussed by Dr. Huberman:
- 16-Hour Fasting: This involves fasting for 16 hours each day and eating during an 8-hour window.
- 24-Hour Fasts: Fasting for a full 24-hour period.
- 36+-Hour Fasts: Extended fasts lasting 36 hours or more.
- Alternate-Day Fasting: Eating normally one day and then not eating at all the next.
- Modified Alternate-Day Fasting: Eating regularly one day and eating very few calories (500 or 600 calories) the next.
- 5:2 Diet: Eating enough calories to maintain adequate metabolism (about 1,200 calories for women and approximately 1,500 calories for men) for five days and then completely fasting for two days.
- Consistent Low-Calorie Intake: Eating very few calories per day (300 to 500 calories) on a consistent basis.
Huberman goes on to say that by following a time-restricted feeding schedule for 60 days or longer, there are metabolic changes that bias weight loss from fat tissue loss as opposed to loss of muscle tissue or sugars stored in muscle for energy.

Considerations for Intermittent Fasting
Intermittent fasting schedules should be tailored to individual needs and preferences, taking into account factors such as lifestyle, activity level, and overall health. While intermittent fasting can be effective for weight loss, it's important to ensure adequate nutrient intake during eating windows and to consult with a healthcare professional before starting any new dietary regimen.
The Importance of Managing Insulin Levels
Considering the nutritional aspect, it's important to manage insulin levels through diet, as low insulin levels facilitate fat oxidation.
Diet, Adherence, Carbohydrates & Insulin
Managing insulin levels through diet is a key component of Huberman's weight loss protocol. Reducing carbohydrate intake can help lower insulin levels, promoting fat oxidation.
Post-Meal Strategies
To further manage blood sugar and insulin levels, Huberman suggests:
- Engaging in light exercise after each meal.
- Taking a 20 to 30-minute walk after eating.
Cold Exposure Protocol
When performed correctly, cold plunging can have beneficial impacts on your brain, your body, and your overall well-being. The goal of this protocol is to activate shivering, which triggers the release of succinate from muscle tissue.

The protocol involves:
- Submerging to your shoulders in cold water.
- Allowing yourself to shiver for 60-120 seconds. Don’t fight the shiver; you can even sometimes facilitate the onset by shivering voluntarily.
- Exiting the tub and standing near it, but don’t cross your arms or dry off.
- Repeating the plunge and exit for 2-5 sets.
(1) Accumulation of succinate controls activation of adipose tissue thermogenesis.
Supplements for Fat Loss
Huberman also examines how supplements such as caffeine, GLP-1 and berberine can further support fat loss.
- Caffeine: Can enhance fat loss when combined with exercise.
- GLP-1 (Glucagon-Like Peptide-1) Agonists: Medications like Semaglutide (Ozempic, Wegovy) and natural alternatives like Yerba Mate can aid in weight loss by regulating appetite and blood sugar.
- Berberine: A natural compound that can improve insulin sensitivity and support weight loss.
Additional Considerations
Sleep and Circadian Rhythm
Prioritizing sleep is crucial for overall health and weight management. Sleep, although not only during sleep, according to Huberman. A consistent sleep schedule helps regulate hormones and metabolism, supporting fat loss efforts. Paying attention to circadian rhythm is also important.
Addressing Overweight Issues
Dr. Huberman recognizes the health risks associated with being overweight. Being overweight in the US is related to increased risk of death, high blood pressure, and elevated cholesterol readings. Addressing these issues through lifestyle changes is essential for improving overall health and longevity.
