Food Foundations: Building Habits You Enjoy

What and when we eat matters.

What we eat and when we eat matters. But within that, there's a lot of room to make it work for you. To build habits you enjoy.

The diet wars distract from fundamentals we all share — fundamentals that still need to be tailored to your unique profile:

• Your genes - how they respond to what you eat

• Your health status - weight, insulin resistance, chronic conditions

• Your life right now - what's actually doable for you

No rigid rules. No going hungry. Just principles to build from.

The Quick Version

1. Eat mostly whole foods

Swap refined starches - most bread, pasta, crackers, or baked goods, for their whole food equivalents. Eat whole fruit, not juice. Once digested, refined starches and juices are just like mainlining sugar.

2. Limit highly processed foods

If the ingredient list reads like a chemistry lab, put it back. Growing evidence links ultra-processed foods to harm in your gut microbiome - especially the good bacteria you want to keep.

3. Eat mostly plants

Feed the good guys in your gut. They need variety to produce the fatty acids your body depends on. Think rainbow colors, fiber, and a wide mix of vegetables, fruits, herbs, spices, nuts, and seeds.

Animal protein? Your call. In modest amounts, it fits comfortably within these principles. Fish is an exception worth prioritizing. But do moderate consumption of large, long lived fish like Tuna; they are prone to higher levels of mercury and other toxins.

4. Choose healthy fats

Extra virgin olive oil, avocado, nuts, and seeds are your go-to sources. Salmon and other oily fish are good for Omega 3 fats.

5. Food first, supplements second

Supplements support a good diet — they don't fix a poor one. Unless there's a specific medical reason, food comes first.

6. Timing matters (this one surprises people)

Aligning your meals with your circadian rhythm may be the single highest-leverage shift you can make, especially if changing what you eat doesn't feel doable right now.

The evidence on risk reduction across almost all common age-related conditions is striking.

• Avoid eating 2–3 hours before bed - digestion competes with your restorative deep sleep.

• Eat breakfast at a consistent time - helps anchor your circadian clock.

• Aim for at least 10–12 hours between your last meal of the day and your first of the next day - time for your body to rest, repair, and restore.

  
  

Knowing Your Whole Foods

Here are a few quick examples for preferential whole foods:

• Whole fruits - not juiced; a fruit bowl over a smoothie when possible

• Whole grains - not grain-derived products like most crackers, bread or baked goods.

• Meat in its natural form - not restructured with additives (most sausages, deli meats, and bacon don't qualify)

• Not this → Restructured foods with unrecognizable ingredients. Pringles chips are a textbook example

The line between whole foods, acceptable processing and ultra-processed foods us a hot topic but nicely simplified with this Harvard Resource. I found it practical and worth the 2 minute read.
