You can do it! I gained 14 lbs, turned things around, and have lost 2 over the past week or so. I lose slowly at under 1500 calories a day.
Breakfast: 1 egg, 2oz lox, 1/2 cup fruit, coffee with a little 1% milk
Lunch: Healthy Choice Powerbowl (low carb) or similar
Dinner: Fish, vegetable, occasionally brown rice or carbanada low carb pasta
Snacks if I am actually hungry: fat free yogurt, banana, 1/2 cup Julian's low carb granola, unsweetened almond milk, low fat cheese stick, etc.
I take a walk/run with my dogs for about 2 miles a day and do Pilates 2x a week. I'd like to add back weightlifting when it's safe to go back to the gym.
Knocking off the number of snacks seems to have been the main issue for me. I would track and see where the extra calories have snuck in and see what you can live without. Good luck!
