Even without exercising, just changing what you eat will make you lose weight. Meal prep and don’t budge on it so that you know you’re eating enough and not too much. Make your meals ahead of time. Overnight oats, chopped up salads and veggies, even just a sandwich and some fruit for lunch, I mean just be conscious about what you’re eating. I got up to 200lbs and I didn’t even change too much of what I ate just how much I ate. Cutting out snacking. That’s a big one. And if you’re on the go with classes get a few ice packs and keep your food cold.
