There is no “best” diet for weight loss because your personal preferences, lifestyle and physiological response to various diets all matter. That being said, diets that may be effective for weight management include low-carb diets like the Bulletproof Diet and the keto diet; intermittent fasting; and the paleo diet. Mindful eating, though not an actual diet, can also help with weight loss by encouraging you to tune in to hunger and fullness cues, which can potentially reduce emotional eating.
