As with anything in life a balanced approach is always the best approach. Any time you go to extremes in making changes in your life you are doomed to failure. Small changes are almost always the best changes to stick with us.
Losing fat does not have to be a very complicated process for you. If you have several failures in your life already it could be simply because the program that you chose in good faith really led you down the path to failure. It is important for you to realize this. You are not the failure. The program was the failure.
The Personalized Approach is the Best One for You
The initial thing that you have to do is simply to decide how important it is to you to lose body fat. This in and of itself obviously will not cause the body fat to spontaneously melt away however it will give you the one essential tool that you need in order to succeed in losing body fat this time.
An important tip is simply to eat what you want. Don't stress out over things that others say you cannot eat. Once your motivation is set in your own mind then one day you can relax, for instance, and eat two scoops of ice cream with chocolate syrup on it knowing that the next day, you're craving having been satisfied, you're likely to only eat a couple spoonfuls of ice cream.
Once you have this set in your mind as your personal policy toward losing fat and body weight you will automatically know what to eat and how much to eat on a day-to-day basis. It is simply a matter of proper focus.
The same point is actually true when it comes to exercise. You are extremely unlikely to start exercising vigorously 30 to 45 minutes each and every day. You may be able to do that on a short-term basis but that is going to become old very quickly for you. It is much more effective to decide that for the next five years you are going to do a 10 minute a day routine. Simply warm up for five minutes then do vigorous aerobic exercise for five minutes. The next day take your five minutes to warm up then do some type of weight bearing exercise for five minutes. And that's it. 10 minutes a day is all that you need and anyone can do 10 minutes a day.
