I've dropped just under that in 3 months. I have wrote about it a few times.
1. I cut my Diet Coke intake in half. Which lowered blood pressure (sodium)
2. I bought a couple of cook books, and started eating only fresh food.
3. I drink a lot more water since cutting out the cola. Sobe Water is good.
4. I drink a smoothie made of fresh fruits and veggies mid morning and afternoon.
5. In month three I added in light weight training and treadmill.
I've dropped 20-25 lbs in just over 3 months. 3 pants sizes. I've shrunk into shirts I haven't been able to wear in a few years. For those smoothies, make sure you get a mix of the soluble and insoluble fibers (help keep you feeling full). For the treadmill I am doing around 1.5 miles in a half an hour a few times a week.
I started out with that Jorge Cruise, "
Belly Fat Cure", and then after the first month moved on to two other cook books with better recipes and more variety. The cook books I looked for were a mix of good looking food, and diabetic (although I am not, nor in danger of) considerations. I focused on eliminating the high sodium processed foods from most of my diet, and controlling sugar.
What I have found, and many others have wrote on this in depth over the years is, you have to adjust your diet. Exercise alone will not do it. It becomes a lifestyle change, not a crash diet. I lost 12 lbs in two months just changing my eating habits with NO exercise at all.
Good luck!
