Go for a run, eat tons of vegetables and protein, try grilling in the oven rather than frying, and drinking lots of water.
Try 2 boiled eggs in the morning with a minimal amount of salt, have a bit of sauce if you want some taste, and eat a salad/fruit/one toast besides it. Then, 3 hours later, have a 150g serving of protein with nothing (tuna, boiled egg, steak, chicken), 3 hours later, have a 200g serving of protein along with vegetables and water/(small serving of) juice, 2/3 hours later, have another 150g serving of protein, and then your final meal (3 hours later) should be similar to your lunch. You should be consuming about 2.5L-3L of water daily. All the protein increases your muscle capacity (when you exercise) which leads to increased metabolism. Furthermore, by eating 5/6 times a day with small portions, you're receiving the correct amount of calories you require daily, staying nearly-full all times of the day (which decreases your food requirement) AND keeping your metabolism working. After 2/3 weeks your metabolism will have improved significantly and you would have lost a healthy amount of weight, making you healthier overall (heart, sleeping pattern, etc).
Your day should go like this as well:
Morning: 8-9am (breakfast)
Brunch: 11-11.30am (1st protein 'snack') --- You should go exercise now, either go for a walk for an hour, go for a light jog for 20/30mins (light) or go for a 10 minute run. Either that, or do 4-5kms power-walking on a treadmill, should take 40minutes.
Lunch: 2.30pm (lunch)
Linner (lunch/dinner): 4.30pm (2nd protein 'snack')
Dinner: 7pm (dinner)
Since your not consuming any carbs EXCEPT for breakfast, you can eat a meal at 7-9pm because they're light proportions and your metabolism is running extremely fast, burning your food off faster than usual.
