Being on a calorie deficit sucks. When you commit to counting calories properly, you quickly realize how many foods and drinks are empty calories. I learned this the hard way by trying to squeeze Snickers into my deficit. I love Snickers but one bar alone wasn’t satisfying and I couldn’t squeeze in more than one without exceeding my deficit for the day. Every time I ate more than one, the calories were consumed, but usually the hunger remained, or at least came back shortly.
