193: Can You Have Weight Loss When You Exercise?

In this episode, the Dr Steve Hughlett explains that whether exercise helps you lose fat depends on your primary fuel source: glucose or fat. The core message is that high insulin from frequent carbohydrate intake keeps the body in storage mode, while keeping insulin low through low-carb or carnivore-style eating helps the body burn stored fat during exercise.

The episode walks through how the body uses glucose and fat for ATP, how glycogen storage is limited, and how fat stores provide far more available energy. It also argues that when insulin is elevated, the body stores more fat and cannot access its own fat easily; when insulin is low, fat can be released and used for energy more effectively.

A major theme is that exercise becomes a stronger fat-loss tool once the body is adapted to burning fat instead of glucose. The host also encourages lowering carbohydrate intake, using time-restricted eating, and removing ultra-processed foods from the pantry as practical first steps.

• Your body can run on either glucose or fat, but the episode argues fat is the preferred long-term fuel source.

• High insulin, usually triggered by eating carbohydrates, pushes the body toward fat storage instead of fat burning.

• Glucose storage is limited, while body fat represents a much larger and more efficient energy reserve.

• Exercise burns more body fat when insulin is low and the body is already adapted to using fat for fuel.

• The episode recommends low-carb eating, time-restricted eating, and removing processed foods to support fat loss and better health.
