i mean they basically are tho. if you’re counting calories, you’re watching what you eat. you’re not eating a big mac combo everyday bc it’s under your calorie limit and expecting to lose weight, unless you’re dumb, in which case an unhealthy BMI is the least of your concerns.
you’re right about insulin responses, but if someone is 350 lbs and eats mcdonald’s every day, telling them to count calories is pretty good advice and most certainly the proper starting point for dieting.
