Let me start by saying that you can lose 25 pounds and even more just by following a healthy lifestyle, exercising more, and keeping a sensible diet.
However, I would like to suggest a diet method which can help you to do it faster.
I'm referring to the Calorie Shifting method which has been steadily gaining popularity over the past few years.
By using a Calorie Shifting method based diet (and there are currently 2 such diets on the market) you can avoid the biggest hurdle of most diets: the slowing metabolism.
Most diets are basically based on depriving your body of either calories or a specific food group like fat or carbs.
Either of these things can lead to an initial weight loss, but can also slow your metabolism down considerably so that you'll see a gradual decline in your weight loss rate, and may even gain it all back when you quit dieting.
This is vitally important since I'm sure you won't be satisfied with just losing 25 pounds, you'll want to avoid gaining them back ever again.
This is done by constantly shifting your calories to produce a metabolic maintenance state.
I know it sounds a bit scientific, but it just works.
The 2 Calorie shifting diets on the market today are called Fat Loss 4 Idiots and Yay Food.
Each of the 2 diets has its own pros and cons.
Fat Loss 4 Idiots has the longer and more proven track record.
It can help you to lose 25 lbs fast.
However, Yay food can also provide you with the jump start and guidance that you need.
Can you lose 25 pounds in a month with either of these 2 diets? The answer is that it's different for each person.
Some may lose 25 pounds in 6 weeks, some may lose 25 lbs in 2 months.
A month seems to me to be a little unrealistic, but even if takes twice as long this is still a great weight loss rate.
I personally know of many people who used Fat Loss 4 Idiots with great success.
I believe that it can also help you to lose 25 pounds fast.
