In 2025, while many things changed around the world, people also shifted their approach to diet trends.
Diets were no longer used solely for losing weight; instead they were focused on maintaining a healthier and more balanced lifestyle.
This year, people paid closer attention to their body types, choosing foods and routines that suited their bodies while keeping their schedules and budget in mind rather than blindly following traditional diets.
Here are some popular diet trends people followed in 2025.
Intermittent fasting
In 2025, intermittent fasting (IF) remains popular for weight loss and metabolic health as it can help regulate blood sugar and blood pressure.
However at the same time some research also shows that intermittent fasting may carry risks for heart health, especially for certain people.
Therefore, individuals should personalize their fasting approach rather than strictly following fixed schedules like 16:8 (16 hours fasting and 8 hours of eating).
