Fad diets, supplements, and unproven therapies (e.g., phytotherapics, probiotics for weight loss) are ineffective and potentially harmful for obesity treatment.
Avoid fad diets and unproven supplements (phytotherapics, probiotics, caffeine supplements) for weight loss. They are ineffective and may be harmful. Focus on evidence-based strategies like calorie restriction and behavioral changes.
These products are ineffective and have potentially harmful effects on health, and are many times created with the only purpose of promoting the marketing of products with a clear conflict of interest biases.
Why this rating
The paper explicitly states there is 'no scientific evidence' for many of these interventions and classifies them as 'not recommended'.

More from this paper
- Calorie restriction (energy deficit) is the primary driver of weight loss, with macronutrient composition having a secondary or negligible impact on long-term outcomes.Good
- Ultraprocessed food consumption is a primary driver of obesity due to high energy density, low satiety, and ease of overconsumption.Good
- Behavioral interventions (Cognitive Behavioral Therapy, Motivational Interviewing) are essential components of obesity treatment, as nutritional guidance alone is often insufficient.Good

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
