The 1pm slump, explained

It isn’t a lack of willpower. It’s simple biochemistry.

We’ve all experienced the dreaded “1pm slump.” You grab a standard sandwich, pasta bowl or bakery pasty for lunch, feel satisfied for about an hour, and by 2:30pm you’re battling brain fog and hunting through the office cupboards for a sugary snack.

Here is the plain-English science behind how swapping a high-carb, low-protein bakery lunch for a SRSLY High-Protein Pizza Bake can transform your energy, appetite and mid-afternoon productivity.

Four reasons it works

What happens after you eat a high-protein lunch?

1

The Hunger Hormones

Why 34g+ of protein helps to keep you full.

When you eat, your digestive system releases hormones that tell your brain whether you are full or still hungry. Protein is the most effective macronutrient at triggering these satiety signals.

Lowering ghrelin

Ghrelin is produced in your stomach and signals your brain that it is time to eat. High-protein meals suppress ghrelin production, helping to turn down the volume on hunger signals after eating.

Boosting PYY and GLP-1

Eating protein stimulates the release of Peptide YY (PYY) and GLP-1—hormones associated with slower gastric emptying and stronger feelings of satiety.

With 34g to 41g of protein per bake, SRSLY Pizza Bakes deliver a concentrated serving of amino acids designed to keep you satisfied throughout the afternoon.

Flattening the Spike

Managing blood sugar and afternoon energy.

Traditional bakery pasties and white-bread sandwiches are often rich in refined carbohydrates. During digestion, these starches break down into glucose and can cause blood sugar to rise quickly.

What can happen next?

  1. The spike: Your pancreas releases insulin to help move glucose out of your bloodstream.
  2. The crash: A rapid rise followed by a drop can leave some people feeling tired, foggy or tempted by quick-fix carbohydrates.

Our Protein Pizza Dough keeps net carbs down to just 10g–11g per bake, providing a lower-carbohydrate alternative to many traditional bakery lunches.

Fewer refined carbohydrates can support a steadier post-lunch energy experience than a carb-heavy bakery meal.

The Thermic Effect of Food

Your body uses energy simply digesting what you eat.

The energy your body expends processing food is known as the Thermic Effect of Food (TEF). Different macronutrients require different amounts of energy to digest and metabolise.

  • Fat: approximately 0%–3% of its energy is used during processing.
  • Carbohydrate: approximately 5%–10%.
  • Protein: approximately 20%–30%.

Because nearly 40% to 50% of the calories in a SRSLY Pizza Bake come from protein, your body uses more energy during digestion than it would processing the same number of calories predominantly from fat or carbohydrate.

Protein has the highest thermic effect of the three main macronutrients.

Complete Protein for Muscle Recovery

All 9 essential amino acids in one convenient lunch.

Whether you are training, running or trying to lose weight while maintaining lean muscle, your body needs a consistent supply of protein to repair and rebuild tissue.

To support Muscle Protein Synthesis (MPS), your body requires all 9 essential amino acids (EAAs)—the building blocks of protein that it cannot produce on its own.

Our proprietary Protein Pizza Dough contains all 9 essential amino acids. Paired with 34g to 41g of protein per bake, it provides a complete protein source without unnecessary levels of carbohydrates.

Complete protein supports the maintenance and recovery of muscle as part of a balanced diet and active lifestyle.
The takeaway

Smart nutrition made simple. Work with your body, not against it.

You do not need a degree in nutritional science or hours of meal preparation to make healthier eating work for you.

By swapping refined starches for a high-protein, lower-carb alternative, you can choose a lunch designed to support fullness, steady energy and muscle maintenance—without giving up the satisfaction of a hot baked meal.
