Just my opinion.... no supplements. They are going to hurt more than help.
Stop jogging if it hurts your knees.
Start eating extrememly well and participate in a regular strength training and cardio program. Pilates is not going to do a darn thing for the fat around your middle area. Pilates is about strengthening muscles.
To lose fat from a specific area, you must reduce overall body fat. You cannot spot reduce (i.e- I wanna lose fat around my stomach so I'll do crunches). That won't work. It will just work your muscles.
Here's 5 tips to lose fat:
1) Eat 5-6 small meals throughout the day. Each meal should be 2-3 hours apart. Each meal should contain one protein and one carb. The first meal should be eaten within an hour after waking.
2) Drink lots of water
3) Rest properly. This means taking at least 24-48 hours between strength training the same muscles, and it also means getting at least 7-8 hours of sleep per night. Lastly, it means taking 1-2 days off from exercising per week.
4) Cardio. This should be done at different intensity levels and different session lengths. Consider doing a low intensity/long session, a high intensity/short session and a few medium intensity/medium length sessions.
5) Strength Training. Strength train each muscle 1-3 times per week. You should lift a proper weight and perform the proper amount of sets/reps for your strength training method.
All of the above things combined will result in fat loss. Good luck
