Cheat Meals, Sauna, and Time Off From Training (Ep 93)
Key Moments
Cheat meals are inadvisable; opt for planned deviations or calorie reserves. Time off training is okay for up to a month, and sauna has modest benefits.
Key Insights
Cheat meals often mirror binge eating behaviors and reinforce rigid dietary restraint, hindering long-term goal achievement.
Alternatives like 'planned hedonic deviation' or 'slack with a cost' offer more control and psychological benefits than cheat meals.
Detraining effects are minimal for up to a month off training, with strength and muscle mass largely preserved.
Older adults experience faster strength and muscle loss compared to younger individuals during detraining periods.
While sauna use mimics some exercise responses, its health benefits are modest and more pronounced in individuals with lower baseline cardio-metabolic health.
Maintaining muscle and strength during prolonged breaks from training is possible with minimal resistance exercise.
THE DOWNSIDES OF CHEAT MEALS
The concept of 'cheat meals' is scrutinized for its negative psychological and physiological effects. Empirically, cheat meals often align with binge eating patterns, characterized by a loss of control over food intake, mirroring psychological disinhibition. This pattern can disrupt goal hierarchies, contradicting fat loss or calorie reduction goals and leading to demotivation. Furthermore, cheat meals reinforce rigid cognitive restraint, creating an unsustainable dichotomy between being 'on' or 'off' the diet, which often results in larger deviations after minor slips.
SUPERIOR ALTERNATIVES TO CHEAT MEALS
To address the drawbacks of cheat meals, more effective strategies are proposed. 'Planned hedonic deviation' involves pre-scheduling a controlled increase in calorie intake on a specific day, serving as a planned indulgence rather than an uncontrolled 'cheat.' This approach can enhance self-regulatory ability, motivation, and self-efficacy. Another alternative, 'slack with a cost' or 'calorie reserve,' involves budgeting extra calories that can be used as needed throughout the week. This method acknowledges that using these calories slows progress slightly, incentivizing their use only when necessary and better aligning with overall goals.
IMPACTS OF DETRAINING ON MUSCLE AND STRENGTH
Taking time off from training results in minimal muscle and strength loss for up to a month, with effect sizes often being trivial. This preservation is attributed to maintaining contractile tissue and motor skills. Perceived losses in muscle fullness are often due to reduced hydration and glycogen stores, which quickly revert upon resuming training. After one month, however, significant declines in force output and performance become more noticeable.
FACTORS INFLUENCING DETRAINING EFFECTS
Several factors influence the rate of detraining. Age is a significant factor, with older adults experiencing a faster decline in strength and performance compared to younger individuals. The training regimen preceding the break can also play a role; while overloading beforehand might theoretically promote supercompensation, it's often impractical and potentially risky. The nature of the time off is crucial: complete immobilization leads to rapid muscle and strength loss (up to 0.5% muscle and 1% strength per day), whereas maintaining some form of resistance training, even at significantly reduced volume, can preserve gains for extended periods.
PHYSIOLOGICAL RESPONSES TO SAUNA USE
Sauna bathing induces physiological responses that bear resemblance to exercise, including increased heart rate and cardiac output, and reductions in certain inflammatory markers. While these mechanisms are fascinating, the tangible health benefits are generally modest and require more robust research, particularly high-quality randomized controlled trials. Many of the widely cited positive outcomes stem from observational studies with potential for reverse causation, where healthier individuals naturally engage in sauna use.
SAUNA BENEFITS AND CONSIDERATIONS
The health benefits of sauna use appear more significant for individuals with lower baseline cardio-metabolic fitness. For those already highly fit, the added benefits are likely diminished and potentially redundant. Sauna is not a replacement for exercise, as it lacks the significant increases in stroke volume that drive many cardiovascular adaptations. However, it may offer modest cardiovascular and cardio-metabolic health improvements and can transiently suppress appetite due to increased body heat. Despite potential benefits, sauna use is a physiological stressor, and individuals with relevant medical conditions should consult a healthcare professional.
