Dietary modifications for weight loss and weight loss maintenance

Area of Science:

• Nutrition Science
• Public Health
• Obesity Management

Background:

• Global obesity rates are increasing, making obesity treatment a public health priority.
• The 2013 AHA/ACC/TOS guidelines suggested dietary approaches are effective for weight loss if they create a sustainable energy deficit.

Purpose of the Study:

• To review and critically discuss dietary modifications for weight loss and maintenance published after the 2013 guidelines.
• To evaluate the comparative efficacy of different dietary schemes for weight loss and maintenance.

Main Methods:

• Systematic review of post-2013 literature on dietary interventions for weight loss and maintenance.
• Critical analysis of studies examining nutrient-, food group-, and dietary pattern-based approaches.

Main Results:

• No evidence supports one dietary scheme being more effective than others for achieving weight loss.
• Evidence for weight loss maintenance is inconclusive, with most research focusing on post-weight loss interventions rather than diet during maintenance.

Conclusions:

• Dietary approaches for weight loss are effective when they achieve a sustainable energy deficit, irrespective of the specific diet type.
• Further research is needed to understand the role of specific dietary patterns in long-term weight loss maintenance.
