At the gym I shock my body by switching my routine. I don't stay with the same weight training exercises for too long and I jog at different speeds and switch it up with walks, stair climbing and bike riding. Burning the last bit of fat on my abs was very hard it took a lot of reading/trial & error. It's as if the fat around your lower abs knows that it has been there for years so it's not going away without a fight, it makes sense it took years to build it around your midsection it wont disappear in a matter of weeks.
I think people need to increase their odds of success by taking small steps and adding a bit of more exercise to their life and then little by little start tweaking their diet to a lifestyle they can transition into. You don't want to lose 20 lbs in a month by starving eating salads and dry chicken breasts with nothing but water and massive cardio. This will result in a short lived weight loss what will most likely happen is that you will hate the change and not only put on the 20 lbs you lost but probably put on an extra 20 lbs. Although I mostly drink water and eat lean protein, fruits and vegetables I didn't make the change overnight otherwise I would have not been able to stick with it. When I started I didnt have the knowledge to know what food was good for me so it is essential to learn to read and understand food labels and the serving size being used.
Here is a healthy snack I like to munch on in between meals: Unsalted Dry Roasted Peanuts
I also eat unsalted cashews and almonds the point is to eat low sodium snacks so it has to be unsalted and remember that it is a snack to be eaten in moderation don't eat it all in one day. I bought the generic type ($2.99) I am not promoting any name brand buy your favorite store name brand if available just as long as you save some money.
