Does it matter what time you should eat to lose bodyweight and if so, what's the best time of day to eat to lose bodyweight?
Analysis on this topic is largely based on research which is observational in nature rather than cause-and-effect. Nevertheless, there does seem to be an observational relationship between metabolic rate, circadian rhythm and meal intake times. When you eat affects your appetite hormone levels (e.g., insulin) which may cause disturbances in your circadian rhythm and lead to metabolic syndrome (i.e., obesity, heart disease, diabetes, etc.). Eating your biggest meal before 3pm tends to cause greater bodyweight loss than eating later.
A recent study in the International Journal of Obesity provides support that eating more food earlier in the day is more effective for losing bodyweight. This study compared two groups of participants: those that ate most of their food before 3pm and those who ate most of their food after 3pm. In both groups, caloric intake, macronutrient composition, activity level, sleep quantity, and appetite hormone levels were similar. The group that ate their biggest meal before 3pm lost more bodyweight at a faster rate than those who ate their biggest meal after 3pm. Other studies support this finding when it was discovered that those people who tend to skip breakfast are more likely to become overweight or obese than those who regularly eat breakfast. The reason for this may be because those people who skip breakfast tend to eat more food later in the day when their metabolic rate is usually reduced, thus perpetuating bodyweight increase.
BOTTOM LINE: Eating most of your food before mid-afternoon when your metabolic rate is elevated may be an effective and healthy habit for you to lose bodyweight. Certainly, avoid eating large late-night meals when your activity level is low--this is a recipe for weight gain!
