Does anyone have any suggestions to boost your metabolism?

Plateaus are the signal that your body gives to let you know that it's time for a switch in your routine. It's also a very natural part of weight loss. I posted a semi-novelish long answer to a similar thread, so this one will be much more concise.

First of all, it's unanimously agreed that as long as you're losing inches, the scale doesn't matter. The feeling of being able to function better, breathe easier, fit into smaller clothes, increase self-confidence, etc., are all more of the motivating factors for achieving optimum health rather than seeing numbers on a machine, that only measures one part of weight loss. As we all know, muscle weighs more than fat, and the like. The short answer all lies in metabolism. And there are ways to get your metabolism going again which most likely has become accustomed to the routine you've set for yourself to lose weight in the beginning.

If you've been doing the same workouts on the same days 5-6x a week, then you could switch up your rest days and trade them for days you normally work out. You could also switch up the routines you do on different days, i.e. if you're doing strict cardio, try adding in some resistance band strength training; if you've already incorporated resistance/strength training for muscles, alternate which muscle groups you do on specific days; introduce your cardio sessions with some HIIT [High Intensity Interval Training]. Those are some ways to confuse your metabolism into thinking that there's something new happening and it needs to become active again to be prepared for the unknown. You can even combine any of those suggestions into something specific for you. As long as it works.

As far as diet is concerned, there are basically two ways to go about it. If you've already established a deficit in calories, your metabolism may be adjusting that set calorie goal to maintain your new weight. By creating another 100 - 200 calorie deficit [as long as it's healthy], it may let your metabolism know that it doesn't need as much, and will therefore burn whatever it thinks is "extra." The inverse is just as true. By increasing your calorie intake by about 100 - 200 a day, your metabolism will start to feel like it needs to burn more because of the sudden increased surplus. Again, the theory can be combined where you eat more on certain days and less on certain days, which will still result in confusing your metabolism.

Just short of another journalistic source of information, the bottom line is that in order for weight loss to occur, your metabolism needs to be stimulated. No matter how you do it, as long as it's in a healthy and manageable way, it can help get anyone over a plateau.
