Good question. You’re right to ask this since yes indeed it slightly goes beyond just being in the state of a calorific deficit. Of course, let’s get this out of the way that a CD is the foundation in that sense this advice is not overrated but perfectly rated. Now, building muscle is the next best thing. Since your basal metabolic rate is increased (keeping muscle is a metabolically costly affair) as a result of it, which means just by sitting around you’d burn more calories with substantial muscle on you relative to you just skinny overall. Secondly, replace carb and fat rich processed foods for ideally high protein foods or just non processed foods overall (do not think carbs are enemies but mitigate high carb processed junk with alternatives). The science behind this is intuitive. Non processed foods and those with protein are highly satiating. They make you more ‘full’. Imagine eating an apple versus a Hershey’s chocolate bar. Regardless of the chocolate bar having 10x the calories of the apple you’ll feel much more satiated after having eaten the apple. Quite the paradox, isn’t it? As a last tip of sorts increase your water intake.
