Fasting & Plant-Based Eating

Two Different Ways of Thinking About Food

Fasting and plant-based eating approach food from different directions.

Fasting asks:

When should I eat?

Plant-based eating asks:

What should I eat?

Combining the two raises an intriguing environmental question.

Could eating less and choosing lower-impact foods produce a larger reduction in food-related environmental impact than either strategy alone?

Why Plant-Based Foods Often Have Lower Footprints

Global life-cycle analyses consistently find that many plant-based foods have substantially lower greenhouse-gas and land footprints than animal products.

That doesn't mean every plant food has a low environmental footprint or that all animal agriculture is identical.

Production methods vary.

But the broad pattern is strong.

Where Fasting Adds Something Different

Fasting potentially reduces the quantity of food required.

Plant-based eating changes the composition of that food.

Together:

Quantity + composition

may be more environmentally meaningful than either alone.

Avoiding a False Choice

There is no need to frame the issue as:

Fasting OR plant-based eating.

They address different aspects of consumption.

A person might:

• Fast periodically
• Eat a predominantly plant-based diet
• Reduce food waste
• Buy appropriate quantities
• Avoid unnecessary consumption

These behaviors address different environmental pressures.

The OneYearFast Question

For OneYearFast, this raises an interesting personal experiment:

Does changing the timing of eating alter the way I choose food when I do eat?

That behavioral question may ultimately be as interesting as the environmental calculations themselves.
