Unless you started exercising, these two statements are incompatible with one another (violates the first law of thermodynamics). What's more likely is you felt "fuller" from eating healthy foods and therefore consumed less calories.
Another possibility is that the food eaten affects the metabolic rate. I've known multiple people who stopped having cold extremities when they cut back on their sugar intake.
