The Truth About Fast Food

Jun 6
2 min read

Fast food companies spend billions researching the perfect combination of salt, sugar, and fat to make food maximally craveable, without being so rich you stop eating. This is documented in food industry science, and written about by former FDA commissioners and food researchers. Your body releases dopamine, the same chemical triggered by some drugs, when you eat highly palatable processed foods. Craving fast food isn't weakness, it’s just your biology being exploited.


What’s actually in a fast food meal?


Take a standard fast food combo: burger, medium fries, and a soda. Here’s what you’re likely consuming:


  • Calories: 1,100-1500 (This is potentially your entire daily recommended intake in one sitting)

  • Sodium: 1,500-2,000mg (close to the daily recommended limit of 2,300 mg)

  • Added sugar: 50-80g in the soda alone, double the daily recommended limit

  • Saturated fat: 20-35g (well over the recommended daily maximum)

  • Fiber: Almost none

  • Vitamins and minerals: Minimal


The Real Coast:


Fast food seems cheap upfront. The real costs are hidden, though:


  • Energy crash: The blood sugar spike from the refined carbs and sugar is followed by a crash, leaving you tired and hungry again within hours.

  • Long-term health: Regular fast food consumption is linked to higher rates of obesity, Type 2 diabetes, and heart disease

  • Mental health: Studies link ultra-processed food diets to higher rates of depression and anxiety in teens

  • Gut Health: Fast food disrupts the gut microbiome, affecting immunity and mood


This Isn’t about never eating fast food


Occasional fast food is not going to ruin your health. The problem is frequency and replacement, when fast food becomes your default instead of an occasional choice.


Some smarter fast food swaps when you have no other option:


  • Choose water or unsweetened iced tea instead of soda, saving 200-300 calories and 50+ grams of sugar

  • Order grilled instead of fried

  • Skip or split the fries

  • Add a side salad if available

  • Choose smaller sizes, as portions at fast food chains are massively oversized
