Metabolic Health & Good Energy

Casey Means' Good Energy protocol steadies blood sugar with simple habits: fiber and protein before carbs, a 10-minute walk after eating. These free, unglamorous habits also include training, sleep, and cutting ultra-processed food, since sharp glucose spikes drive energy dips and, over years, metabolic disease. A continuous glucose monitor and a few key blood markers can show your personal response.

Difficulty
Beginner
Sharp glucose spikes and crashes drive energy dips and, over years, metabolic disease.
The protocol
Each meal
Eat fibre and protein before carbs Vegetables and protein first, starches and sugars last

Meal order meaningfully blunts the glucose spike.

Good Energy
After meals
Walk for about 10 minutes A short walk after eating, especially after the largest meal

Muscle contraction clears glucose from the blood without insulin.

Good Energy
Daily
Build meals from whole foods Minimise ultra-processed food; prioritise protein, fibre and healthy fats

Ultra-processed food is the main driver of the spikes and crashes.

Good Energy
Foundation
Train, sleep and manage stress Regular movement (including strength), consistent sleep, stress down-regulation

These move the same metabolic markers as food does.

Good Energy
Supplement
Cover magnesium and the basics Magnesium daily if intake is low; omega-3 and vitamin D as needed

Magnesium supports glucose transport and vitamin D processing; she frames supplements as gap-fillers, not the main event.

Is this for you
  • Energy crashers
  • People with pre-diabetes risk or family history
  • Data-driven learners
  • Anyone who wants free habits before any gadget
Cautions
  • Means co-founded Levels and has a commercial interest in the CGM and testing recommended here. Continuous glucose monitoring is optional and, for people without diabetes, evidence of clear benefit is limited
  • History of disordered eating: continuous glucose tracking can tip into food anxiety and obsessive monitoring; this protocol may not be appropriate, and the habits above work without any device
  • Diabetics: coordinate any change and any CGM use with your doctor
  • The CGM subscription is expensive and entirely optional; the meal-order and post-meal-walk habits are free and carry most of the benefit
  • Educational only, not medical advice
Common questions
Why do I get brain fog every afternoon?
A common cause is a post-meal glucose spike and crash: sharp blood sugar swings after eating can leave you foggy and low-energy an hour or two later. Eating protein and fiber before carbs, and walking for about 10 minutes after meals, blunts the swing for many people. Persistent brain fog can also come from poor sleep, dehydration, or other causes, so if this does not resolve it, it is worth mentioning to a doctor.
