5. Study Description
Brief Summary
Investigators presumed that preload consumers will have more weight reduction and lower risk of cardiovascular disease
Detailed Description
To our knowledge, all previous studies evaluated the energy intake in a dietary meal after consuming a low-energy-dense preload while none assessed the sustainability of lower amount of energy intake and body weight changes in a long-term. On the other hand, the sustainability of lower energy intake in a long term might be affected by higher dietary diversity score due to considering preload in diets. Notably, increased diet variety is associated with higher overall dietary energy intake and weight gain.

Intervention Type
Other
Intervention Name(s)
preload diet
Intervention Description
All participants were prescribed a calorie-restricted diet (-200 to -500 kcal/d). Calorie requirements of each subject were estimated based on resting energy expenditure (REE) by using Harris- Benedict equation and also considering the physical activity levels. The diets were constructed to provide similar proportions of carbohydrates (55% energy), protein (15% energy) and total fat (30% energy).
