What happens when you stop eating meat?
When you stop eating meat, your body goes through both short-term adjustments and long-term changes. Some are beneficial, others depend on how well your diet is planned.
First few days to weeks
1. Digestion may feel lighter
Less stomach acid is needed.
Some people notice less bloating or heaviness.
Others may feel gassy at first as gut bacteria adjust.
2. Energy levels may change
You might feel lighter and more energetic if you replace meat with whole foods.
Poor replacements (white bread, sugary foods) can cause fatigue.
3. Weight may drop slightly
Reduced calorie density.
Higher fiber intake increases fullness.
After weeks to months
4. Cholesterol and heart health may improve
Lower intake of saturated fat can reduce LDL (bad) cholesterol.
Better blood vessel function.
5. Improved gut health
More plant fiber feeds good gut bacteria.
Improved digestion and bowel regularity.
6. Reduced inflammation (for some people)
Especially when processed meats are eliminated.
Joint pain and skin issues may improve.
Possible deficiencies if not careful
7. Vitamin B12
Only found naturally in animal foods.
Deficiency can cause fatigue, nerve problems, memory issues.
8. Iron
Plant iron (non-heme) is less absorbable.
Low iron may cause weakness or dizziness, especially in women.
9. Protein
Can still be met, but requires planning (beans, lentils, eggs, fish if allowed).
10. Omega-3 fats
Lack of fish may affect brain and heart health.
Mental and hormonal effects
11. Mood changes
Some people feel mentally clearer.
Others may experience low mood if protein, B12, or iron drops.
12. Hormonal balance
Adequate fats and protein are essential; poor planning may disrupt hormones.
Bottom line
Stopping meat can be very healthy if your diet includes:
Legumes (beans, lentils)
Eggs or dairy (if not vegan)
Vegetables and fruits
Nuts, seeds, healthy oils
B12 (supplement or fortified foods)
If done poorly, it can lead to fatigue, weakness, and nutrient deficiencies.
