Hmm, lose if fast gain it fast. That's what's more than likely to happen if you lose the weight fast. This happens for various reasons.
Primarily it has to do with the mindset. Focusing on fast weight loss tends to rely on methods that aren't possible to keep up for the long term. So once you reach your "goal" and revert back to "normal" habits... you rebound. Generally this rebound is quite bad for a bunch of reasons.
Have you read the stickies?
If not, do so. They'll help you tremendously.
Trimming your body up, which is simply a function of losing fat while gaining/maintaining muscle, is going to come from smarter nutrition and appropriate exercise.
Smart nutrition in your case:
- Calorie deficit of 30% or so (see stickies)
- Balanced, satiating meals
- 1 gram of protein per pound of goal body weight
- 30% fat or so coming primarily from the good stuff (fish oils, avocados, nuts, flax, olive oil, etc)
- Majority of carbs coming from veggies and fruits. Throw the "other carbs" (whole wheat pasta, bread, oats, etc) in in moderation
- Shy away from processed food as best as possible (this is more for health than fat loss)
- Avoid calorie-containing beverages best as possible
Appropriate exercise:
- Should be doing some form of resistance training 2-3 times per week. Ideally this comes by way of weight lifting, assuming you have access to weights or a gym. (see stickies for more info)
- Various intensities and volumes of metabolic work (which some would call cardio) most days of the week. Beating your body into submission is certainly not the answer. Some people go hog wild with high intensity "cardio (aerobic and anaerobic for those who want to get nitpicky) and that's silliness when the goal is fat loss.
That's in in a nutshell. If you want to ask specific questions, we're all ears. But I definitely suggest reading the stickies first.
