diet is the key. Until you diet and understand a diet, its going to be very hard to lose weight. Truly, you are looking for fat loss, not water loss. Lots of motivation in the beginning when you shed some water weight, but you might not see much of a difference in your body.
Step it up and eat 6 meals a day.... every 3 hours, from the minute you wake up to right before bed. Yes, eat something 10 minutes before bed. You need to trick your body into letting go of fat. Your body needs to know that its not going to be starved between meals. Eat a good 1800-2100 calories a day and work out. You do need cardio, but a moderate cardio. The goal is to have your heart rate in the 140-150 range for an extended period of time...could be lower depending on your resting heart rate.
If you get your heart beating to fast, the exercise becomes anaerobic and you will start burning glycogen from your liver, and your body will not start burning fat. You have something like 400g of disposable glycogen. The key is to not tap into that glycogen storage and allow your body to consume energy elsewhere (fat, hopefully). Also, starving yourself and not working out your WHOLE body can lead to atrophy of the muscles. It is much easier for your body to break down proteins for needed energy than it is for fat. Fat is LONG TERM storage.
Throw all the crappy foods out the window. Sodas, beer, candy, ice cream, potato chips, etc. Focus on anything healthy. Salads can be tricky...you need to watch your dressing. Some salads at restaurants have just as many calories in a salad as they do in a freaking hamburger. Chili's Caesar salad has something like 1200 calories
For exercise, watch that heart rate. For me, I would walk on a treadmill at 3.5mph at an incline of 3%. Thats a brisk walk. A good 30-45 minutes of that a day along with diet will really get you going.
Ditch the G2...its extra calories that you dont need. More small meals. There is no such thing as spot reducing fat. 1,000 situps a day isnt going to make you lose fat out of your stomach area...just doesnt work that way.
I'm no expert, but have been a successful personal trainer for 4 yrs now.
I think what was said here by 8mpg was something you should read over a few times and remember it.... But I'd like to add some things...
You and I may not be a like, however our engines can run pretty much the same. Introduce your body to more meals with fewer calories/smaller portions like stated above. Your body will step it up metabolically. You can also aid the process with increased water intake. Stray away from "G2" or anything else containing unwanted calories. If this is supplemental intake is for "electrolytes", and you're not currently very knowledgable of food/nutrition then I can almost be certain that you're taking in the needed electrolytes through your new 6 meal a day LIFESTYLE.
Now for cardio... Follow this as far as finding YOUR range for fat burning.
1. Calculate your maximum heart rate
The easiest way to do this is a simple paper-and-pencil calculation. Subtract your age from 220. The result is an age-predicted maximum beats per minute.
This method does not take into account your fitness level or inherited genes, which can make your true maximum heart rate 10 to 20 beats per minute higher or lower than the age-predicted number.
A second method to calculate your maximum heart rate is to have an exercise tolerance or stress test. This usually is supervised by a physician and performed in a hospital or clinical setting in three-minute stages, during which the speed and incline continue to increase in an effort to elevate your heart rate until it climbs to its highest level.
2. Determine your resting heart rate
Take your pulse before you get out of bed in the morning. Do this for several days in a row to get consistent readings.
3. Calculate your heart-rate reserve
Subtract your heart's resting rate from your maximum rate.
For example, if you are 40 years old, subtract that number from 220; your maximum rate is 180. Next, subtract your resting rate, 80 in this example. Your heart-rate reserve is 100 beats per minute.
This heart-rate reserve represents the cushion heartbeats available for exercise.
4. Calculate your aerobic training heart-rate range for fat burning
This fat-burning range will lie between 50 and 75 percent of your heart-rate reserve.
Using the example above, 50 percent of 100 beats per minute is 50. And 75 percent of 100 is 75. Next, add your resting heart rate to both numbers: 50 + 80 = 130 and 75 + 80 = 155. Your heart rate during aerobic training that will most efficiently burn fat is 130 to 155 beats per minute.
Again, you can't "spot check" fat. As stated, if it resides on your belly, then you've got work to do. Your abdomen is like any other muscle, in the way that if you work it, size can be gained which may result in you seeing them sooner.
I like to think of weight loss/gain in mathematical terms. Easy to remember too.
1lb of fat= 3500 calories
I'd suggest finding out what your "resting metabolic rate" is or "RMR". Not necessary but could give you a better idea on how to structure your new lifestyle.
Your RMR is 1800calories
Daily calorie expenditure is 800 calories
Complete Daily Expend =2600 cal
Your intake is 2200 cals
You will have burned 400 more than you took in. In 9 days you would have lost 1 pound of fat.
Now that's the easy way to look at it. There are variables and more to it, but you get the idea. I find that this really helps clients with motivation and focus with their plan.
Most importantly you have to love doing it and make it a lifestyle, not just a "fad".
I'll be the first to say personal training is the biggest bullshit of a job. If you read, find what you love... then there's no reason why you can't get where you want to. I do it cause I love to help others but my job is getting harder and harder. There's a plethora of knowledge that anyone and everyone has access to out there.
Hope this helps... I feel I skipped around a bit.
