What is the best way to lose fat


Optimizing fat loss can be achieved through a combination of dietary management and exercise. Here are the key points and strategies based on 's insights:

  1. High-Intensity Interval Training (HIIT):

    • Engaging in high to very high-intensity training, especially when followed by low-intensity activities, can optimize fat loss. HIIT stimulates significant adrenaline release, which is crucial for activating fat oxidation and thermogenesis. 1
  2. Nutritional Considerations:

    • Managing carbon intake is crucial. Fat loss isn't just about counting calories but also about understanding the metabolic impact of different macronutrients, primarily how the body processes carbon from fats and carbohydrates. Reducing carbon intake or increasing carbon expulsion (through breathing during exercise) is effective for fat management. 2
  3. Exercise Sequence and Types:

    • The sequence and type of exercise matter. Performing cardiovascular exercises after strength training can be beneficial. Different types of exercises—HIIT, sprint interval training (SIT), and moderate intensity continuous training (MICT)—affect the metabolism and hormonal activity differently, which in turn impacts fat loss. 3

      Optimize Fat Loss

      Andrew explains how high-intensity training followed by low-intensity training can optimize fat loss. He also discusses the role of adrenaline in fat loss and how it is triggered by movement of any kind.

  4. Sustainable Nutritional Habits:

    • Long-term sustainability of dietary habits is crucial. Avoid extreme diets that are not sustainable. Lowering excessive fat and sugar intake is generally beneficial, and maintaining a balanced diet supports overall health and fat management. 4
  5. Neurological Factors:

    • Consider the neurological components of fat loss, such as the role of NEAT (Non-Exercise Activity Thermogenesis) and the significant role played by the nervous system in regulating fat loss. This includes understanding how the body uses cold exposure, brown fat, and beige fat to increase calorie expenditure. 5

These methods provide a scientifically backed approach to losing fat, emphasizing a balance between exercise intensity, nutritional management, and the understanding of physiological processes behind fat metabolism. Implementing these could help in effectively reducing body fat while ensuring the practices are sustainable and health-promoting.

I am a 24 year old male. I weighed 184 pounds two weeks ago. I was eating unhealthily and getting little excercise. In the past two weeks I have excercised well and reduced my caloric intake. I have lost 10 pounds in this span of time. I am aware that as time goes on, I won't lose excess weight at the same rate that I have recently. Can you estimate how much harder it becomes to lose weight as you become more fit?


As you progress in your fitness journey and become leaner, losing weight can indeed become more challenging. This is due to several physiological and metabolic adaptations:

  1. Metabolic Rate Changes: As you lose body mass, your metabolic rate can decrease, as there's less body mass to maintain. This can slow down weight loss over time.

  2. Adaptive Thermogenesis: When you reduce caloric intake and increase exercise, the body sometimes adjusts by lowering energy expenditure in other physiological processes to conserve energy, making further weight loss more difficult.

  3. Decreased Insulin and Leptin Sensitivity: Changes in hormone levels, such as insulin and leptin, which are important for appetite regulation and metabolism, can also make further weight loss more challenging.

  4. Loss of Lean Muscle Mass: Significant caloric restriction can lead to not just fat loss but also muscle loss, unless properly managed with resistance training and adequate protein intake. Muscle is metabolically active, so losing it can decrease the rate at which you burn calories.

  5. Aging: Furthermore, aging impacts fitness and the body's ability to lose weight efficiently. Metabolic rates and physical capabilities often decrease with age, requiring adjustments in diet and exercise intensity and types. For instance, the maximal uptake of oxygen (VO2 max) declines by about 8-10% per decade, indicating decreasing efficiency in the body’s utilization of oxygen for energy production as one ages 1.

Overall, as you progress, it's important to adjust your weight loss strategy, considering these factors. Regular fitness assessments, consulting with fitness professionals, and perhaps resetting your goals based on new metabolic rates can help you continue to progress effectively in your fitness and weight management journey.

Backcasting Approach

Peter and Andrew discuss the backcasting approach to achieving long-term health goals. By breaking down objectives into measurable metrics and assessing where you need to be in the future, you can better understand the gravity of aging and the level of fitness required to maintain health.

how early should i drink coffee before excercising


For optimally timing caffeine intake specifically for exercise, it is recommended to ingest caffeine about 30 to 60 minutes before exercising. This timing allows the caffeine to be absorbed and to start taking effect, enhancing both mental and physical performance during the workout 1.

However, if you typically engage in intense exercise shortly after waking, mentions it's acceptable to consume coffee or other caffeinated beverages just prior to the exercise session. He also notes that depending on your regular caffeine habits and sensitivity, this might influence how soon you feel its effects 2. Moreover, the benefits of pre-exercise caffeine can vary based on your individual adaptation to caffeine and how it affects your body temperature and blood vessel behavior during workouts 3.


Andy and Andrew discuss the benefits of caffeine as a stimulant for mental and physical performance. They recommend taking 1-3 milligrams per kilogram of body weight about 30 minutes prior to exercise for the best results.

If your schedule allows, and especially if you don't exercise immediately after waking or if you experience afternoon fatigue, delaying caffeine intake until about 90-120 minutes after waking is also beneficial. This delay can help mitigate the intensity of the afternoon energy dip typically associated with earlier caffeine consumption 2.

For tailored advice, consider your own body's response to caffeine, your exercise timing, and your overall daily routine.
