Man oh man, have I ever. But - let me ask you a few questions, questions I was once asked by my doctor, and once I was provided the answers, suddenly my workouts helped my loss tremendously.
How long have you been at this new routine of both exercise and diet? You said 1-1/2 weeks? Are you aware you will retain water the first several weeks of starting a new reginme, anywhere from 3-6 weeks? That water is used to repair your muscles and to replenish what your body thinks is dehydration. Drink more water, especially AFTER exercise (within 30 minutes is prime) and you should see SOME movement downwards.
Muscle does not weigh more than fat, a pound is a pound, but a pound of muscle is MUCH smaller than a pound of fat. Have you taken up the tape measure? The scale is NOT an accurate measure of health. Anyone can lose weight. Weight loss can be anything from water weight, to muscle mass, to bone loss, and so on. What you want is FAT loss, not weight loss. As you gain muscle, you will burn fat. The poundages may stay the same, and in some cases go up, at least at first, but the inches WILL go down, which means fat is going down. Which is a better gauge of health than the scale. And after a while, those muscles that are weighing you down will become more efficent in burning the fat (MUCH more efficent than not having them) and you will start seeing losses again, sometimes rapidly, sometimes slowly.
You say you are keeping your calories at 100% but are you eating the right amount of calories? And the right amount of protein. I'm not suggesting a high protein/low carb diet, but only that you are getting the recommended amounts of protein for your weight. That helps protect your muscles as you exercise so the loss is in the right place and not at your muscles, which can target your heart. Are you keeping in range with your BMR/RMR? Knowing those numbers makes the difference between losing weight and maintaining and gaining. 100 calories a day can make a difference. You are more than welcome to take a gander at my spreadsheet
HERE, I just ask you don't alter any forumlas, but only enter in the appropriate values. Your BMR/RMR changes as you age and as you gain/loss weight. It's a good idea to look at it every 20 pounds or so.
Also, what kind of exercises are you doing? And what is your heart rate at? Fat loss is sped up most by cardio exercises and by keeping your targeted heart rate at the recovery or aerobic zone.
There are THREE different heart rates you need to aim for. Each one is important in its own way.
RECOVERY ZONE (often time called the "fat burning zone") - This zone reaches at 60 percent to 70 percent of your maximum heart rate. Training in this zone can build your low-level cardiovascular endurance, and in more elite athletes can be used to replenish glycogen to the muscles during interval training. Your body burns mostly fat in this heart rate zone, making it a favorite for those trying to lose weight without putting forth more strenuous effort.
AEROBIC ZONE (often times called "cardiovascular zone") - The aerobic zone is the most common zone achieved during exercise. Your heart rate is between 70 percent and 80 percent of maximum in this zone. Cardiovascular health and efficiency both benefit from training in the aerobic zone. Endurance athletes such as distance runners and cyclers train often in this zone to improve the efficiency of their oxygen intake and usage. Most calories burned in this zone are from fat, making it an ideal zone for moderately fit people to burn calories and lose weight.
ANAEROBIC ZONE - Anaerobic exercise, performed when your heart rate is between 80 percent and 90 percent of maximum, is difficult, and can rarely be performed for long periods of time. Anaerobic training is most important for athletes in sports that cause very high heart rates, such as short-distance running, U.S. football, basketball and tennis. During anaerobic exercise, glycogen stored in muscles is used as energy instead of fat. Processing glycogen creates lactic acid as a byproduct, and training in this zone is targeted toward improving your body's ability to deal with lactic acid buildup. Generally, training anaerobically is appropriate only if you are already fairly fit. You will not lose weight in this zone, but is effective for those trying to maintain.
There is one other zone remaining. However, unless you are an elite athlete, you do NOT want to be in this zone. In fact, you should avoid this zone like the plague because this zone is flat out dangerous if you don't know what you are doing.
RED LINE ZONE - The red line zone, from 90 percent to 100 percent of maximum heart rate, is entered only for brief periods and should be avoided by all but the most fit athletes. Training in this zone improves fast-twitch muscles useful to athletes in sports that require sudden bursts of speed or power. Working out with your heart rate in this zone is also necessary to improve your body's VO2 Max. Beware, however, of reaching this zone in your workouts if your fitness level is not high or if you have any history of cardiovascular disease.
The best way to figure up your zones is to use the method developed by Doctor Bill Haskell and Doctor Sam Fox. The "220 minus age" formula. The equation took the number 220 and subtracted a person's age from that number to estimate an individual's maximum heart rate. So, for example, let's figure my ideal rates. I am 30 so:
220-30 = 190 is my maximum
Recovery Zone is 60-70% of the maximum, so my heart rate should be between 114-133
Aerobic zone is 70-80% of the maximum, so my heart rate should be between 133-152
Anaerobic zone is 80-90% of the maximum, so my heart rate should be between 152-171
The red zone is 90-100% of the maximum, so my heart rate should be between 171-190
Working out too hard or not hard enough can net no added benefits. Make sure to stay in your sweet spot.
