Added Sugar Science: What It Does in the Body and How It Differs from Natural Sugar
How added sugar is metabolized, how it differs from natural sugar at the molecular level, why dose and food context matter, and what the WHO guidelines actually say.
BeginnerHFCS: Is It Really Worse Than Sugar?
Is high fructose corn syrup bad? We compare HFCS to sugar, explain fructose metabolism, and give you the honest answer about what the research shows
BeginnerHow Alcohol Is Metabolized: The ADH Pathway, Acetaldehyde, and Why Calories Count
Alcohol goes through ADH then ALDH enzymes, producing toxic acetaldehyde along the way. Here's how the metabolism works and what it means for calories.
IntermediateHow Carbohydrate Metabolism Works: From First Bite to Fuel
How carbohydrate digestion and metabolism works: amylase, GLUT transporters, glycolysis, glycogen storage, and when excess carbs become body fat.
IntermediateHow Fructose Is Metabolized Differently from Glucose
How fructose metabolism differs from glucose: the KHK enzyme, bypass of phosphofructokinase, de novo lipogenesis in the liver, and why dose and food source both matter.
AdvancedHow Metabolic Rate Works: BMR, TEF, NEAT, and What Actually Changes It
How metabolism works: the 4 components of total energy expenditure, what genuinely affects BMR, why 'slow metabolism' is usually overstated, and adaptive thermogenesis.
BeginnerIntermittent Fasting: What the Research Actually Shows
Does intermittent fasting work? Honest look at the evidence on weight loss, metabolism, autophagy, and who intermittent fasting actually helps.
IntermediateSugar: From Kitchen Chemistry to What Your Body Does With It
Sugar does different jobs in cooking and in your body. Here's the chemistry of caramelization, Maillard browning, and how sucrose becomes glucose and fructose.
IntermediateWhat Is Insulin Resistance and How Does It Develop?
What insulin resistance is and how it develops: insulin receptor signaling, GLUT4 translocation, ectopic fat, and the role of exercise in improving sensitivity.
