Combining Diet and Exercise Moast Effective for Preventing Abdominal Fat Gain

Improving diet and increasing physical activity levels together may be more effective at preventing weight gain – particularly harmful fat inside the abdomen – than just changing one of these behaviors, new research from the University of Cambridge suggests.

The Power of Combined Lifestyle Changes

An analysis of changes in physical activity and diet quality in UK adults found that while improved diet quality and increased physical activity were each independently associated with lower increases in body fat, the greatest benefits were achieved by combining both.

Understanding Different Types of Body Fat

Body fat is stored in different locations, some of which are more harmful than others. Subcutaneous fat is stored under the skin and can be considered relatively healthy. In contrast, visceral fat stored around the organs in the abdomen is linked too a higher risk of diseases such as type 2 diabetes, fatty liver disease, and heart disease.

The Fenland Study: A seven-Year Examination

A study published in JAMA Network Open, researchers from the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge followed 7,256 adults from the Fenland Study over seven years.

The mean age of the study participants was 49 years at baseline, and 56 years at follow-up. At baseline, and again after an average of around seven years, the researchers measured Fenland study participants’ physical activity levels and diet quality.

Study methodology and Measurements

Researchers used questionnaires to assess dietary intake and accelerometers to objectively measure physical activity. Changes in body fat were measured using MRI scans. This allowed them to differentiate between increases in total body fat and changes in visceral fat specifically.

Key findings of the Research

The study revealed that individuals who both improved their diet and increased their physical activity experienced the smallest increases in total body fat and, crucially, the most important reductions in visceral fat accumulation.

• Improved diet quality alone was associated with lower increases in total body fat.
• Increased physical activity alone was also linked to lower increases in total body fat.
• However, the combination of both interventions yielded the most substantial benefits, particularly in reducing dangerous visceral fat.

Implications for Public Health

These findings underscore the importance of a holistic approach to weight management and disease prevention. Focusing on both diet and exercise, rather than relying on a single strategy, is likely to be more effective in promoting long-term health.

FAQ

Q: What is visceral fat and why is it harmful?

A: Visceral fat is fat stored around the organs in the abdomen. It’s linked to a higher risk of type 2 diabetes, fatty liver disease, and heart disease.

Q: How was physical activity measured in the study?

A: Physical activity was objectively measured using accelerometers, devices worn by participants that track movement.

Q: What does “diet quality” refer to in this study?

A: Diet quality was assessed through questionnaires, focusing on the types of foods consumed and their nutritional value.

Key Takeaways

• Combining a healthy diet with regular physical activity is more effective for preventing weight gain than focusing on just one.
• reducing visceral fat is crucial for lowering the risk of serious health conditions.
• Objective measurements of physical activity and body composition provide more accurate results than self-reported data.
