The choice between diets like carnivore, keto, or vegan is less important than long-term adherence. Before starting any restrictive eating plan, ask: "Can I see myself doing this for the rest of my life?" If the answer is no, the approach is unsustainable and likely to fail.
The fear that creatine causes hair loss stems from one 2009 study that measured an increase in a DHT, a hormone linked to hair loss, but did not measure hair loss itself. The study has not been replicated, and there is no robust scientific evidence directly linking creatine supplementation to hair loss.
Daily weight can fluctuate by 5-6 pounds due to fluid shifts, a major reason people abandon weight loss efforts. To accurately track progress and maintain motivation, weigh yourself daily under consistent conditions but only compare the seven-day average from one week to the next.
The amino acid leucine is the primary driver of muscle protein synthesis. Research shows that lower-quality plant proteins (like wheat) can produce a muscle-building response identical to high-quality whey protein simply by adding supplemental free leucine. This is an effective strategy for vegans to optimize muscle growth.
For every 100 calories of protein consumed, your body uses 20-30 calories for digestion and processing (the Thermic Effect of Food). This is a significant metabolic advantage over fats (0-3% TEF) and carbs (5-10% TEF), making high-protein diets more efficient for weight management.
The primary danger of ultra-processed foods isn't their ingredients but their hyper-palatability. In a controlled study, when subjects were given access to ultra-processed foods, they unconsciously increased their daily intake by 500 calories compared to when they ate minimally processed foods, leading to weight gain.
Non-Exercise Activity Thermogenesis (NEAT)—energy from fidgeting and other non-purposeful movements—is the most modifiable component of daily energy expenditure. It can account for hundreds, and in some cases nearly 1,000, of calories burned per day, a significant and often overlooked lever for weight management.
Food labels are legally permitted to have up to a 20% error margin. However, since the error for a specific product is typically consistent, tracking still provides a reliable relative measure. If you consistently track and don't see results, you can adjust intake based on your consistent (though imperfect) data.
Despite popular theories, human randomized controlled trials do not support the claim that seed oils are inherently inflammatory. When polyunsaturated fats (from seed oils) replace saturated fats, the effect on inflammation and cardiovascular markers is typically neutral or even positive. The real issue is overconsuming calories from any added oil.
