Energy balance
Lifestyle modifications, specifically calorie restriction of 500-750 kcal/day and ≥ 150 minutes of exercise per week, are the first-line treatment for obesity, though long-term maintenance is challenging without pharmacological or surgical support.
Start with a daily calorie deficit of 500-750 kcal and aim for at least 150 minutes of exercise per week. This is the first step in managing obesity. Remember, long-term success is often about finding a sustainable lifestyle you can stick to, rather than a specific 'magic' diet.

Energy intake reduction of 500–750 kcal per day can manifest in an initial weight loss of 0.5–1.0 kg (1.0–2.2 lbs) per week... Physical activity... ≥ 150 min of exercise training a week is associated with weight loss induction [11] and maintenance... Notably, the limited long-term success of most diets is less often due to the specific macronutrient composition or structure of the diet itself, and more commonly attributable to challenges with sustained adherence over time.
Why this rating
Supported by multiple RCTs and meta-analyses, though long-term adherence is a known limitation.

More from this paper
- Semaglutide 2.4 mg once weekly is a highly effective treatment for obesity, leading to an average 14.9% body weight loss in nondiabetic adults over 68 weeks, and reduces major adverse cardiovascular events (MACE) in patients with obesity without diabetes.Strong
- Liraglutide 3 mg daily is an effective pharmacological intervention for chronic weight management, producing a mean 5.2 kg placebo-subtracted weight loss at 1 year, with generic availability potentially improving cost-effectiveness in resource-limited settings.Good
