Electrolytes: Sodium, potassium, magnesium, calcium
Carbs are NOT the enemy of all weight loss. You're active, you can probably use them. I'd replace some fats in your diet to stay within your calorie range and eat some more good carb sources, like oranges (Hey, you're in FL!), potatoes with lots of salt, white rice, carrot salad with raisins, dates, etc. I'd suggest making homemade "Gatorade" with orange juice and salt; soak your feet in Epsom salt or take a whole Epsom salt bath for magnesium. I like Natural Calm supplement for magnesium as well, but Epsom salt soaking is probably safer and easier on the tummy. So important to keep your electrolytes balanced, especially in hot and humid conditions. I've experienced heat-induced dehydration and it's pretty scary but avoidable.
