You undoubtedly have heard of metabolism and may even have a vague idea of what it is. But there are many myths about its impact on health, especially in terms of weight loss. Does your body digest the calories you consume before bed like it does the rest of your food, or is it different?
According to recent research, eating the majority of calories later in the day appears to unaffected overall calorie burn. The impact of meal timing on hunger and metabolism in obese individuals was studied. One set of participants consumed most of their daily calories in the morning (a morning-loaded diet). At the same time, the other group received most of their calories in the evening (an evening-loaded diet). Researchers assessed each group's energy expenditure, hunger hormones, and subjective feelings of hunger while they adhered to their designated eating plan for a month.
The researchers regulated each participant's food intake to guarantee that each person consumed the same number of calories. The majority of calories were consumed afterward. According to the study, there were no discernible changes in appetite or metabolism between casein-consuming and non-consuming subjects.
Protein before bed won't miraculously increase or decrease your metabolism if you're already getting plenty of it each day. However, if you train frequently, eating additional protein at night may still help with muscle regeneration and nighttime protein synthesis.
The impact of a protein snack at night on sleep may be the only additional factor to be taken into account. Eating too close to bed can impact how fast you fall asleep and the quality of your sleep, including REM. Over time, disturbed sleep may cause appetite to increase. Therefore, it's ideal to eat your last meal of the day if you eat later in the day.

Therefore, it is often advised to consume your last meal two to three hours before bed if you eat later in the day.
