Healthy weight loss!?

Hi all, I’ve noticed my weight starting to creep up around 16mo into my breastfeeding journey, Ive been eating - lot of low nutrient processed stuff due to being so busy and stressed. I thought I’d try reducing added sugar and dairy as this generally helps me feel better and maintain a healthier weight. 1 day in I’ve had a crazy hypoglycaemia episode (not diabetic as far as I’m aware), sweating, uncontrollable shaking, extreme hunger. Also have just started my first real postpartum period, which probably doesn’t help How did you guys trim down a little in a healthy way? Even though my LO is eating decent amounts of solids I feel like I’m still very sensitive to hunger, obviously cutting out snacks isn’t really working.
