That's not a huge dent in your diet when you consider the government recommendations for a moderately active male aged 36 to 40 is 2,600 calories a day. It’s 2,000 for a woman in the same age group.
But who can stop at one burrito?
If you eat 4 ounces of chips you're adding about 540 calories – 230 of those from fat.
If you add a half cup of guacamole, the non-profit group Livestrong Foundation says you can add 155 calories. One tablespoon of sour cream ticks your total up another 31 calories: 54 from fat.
So, if you're eating a 450 calorie burrito with chips, guacamole, and sour cream, you’re easily consuming 1,000 calories or more.
