These hormones regulate how your body uses energy (and burns fat). “When your thyroid is underactive, your body uses less energy while you're in rest mode, leading to weight gain over time," says Moskovitz.
A new exercise regimen puts stress on your muscle fibers. This causes small micro tears, also known as micro trauma, and some inflammation. Those two conditions in your muscle fibers are the reason you may gain some weight.
One of the main reasons why burning calories through exercise may still not result in weight loss is due to overexertion, or inflammation of your body. If you exercise too hard on a daily basis, there is an excess of inflammation in your body. All the added up inflammation makes you gain more weight than lose.

You'd think that going on a strict diet and exercise regimen would help you drop pounds quickly, but most people actually gain weight at first. If this has happened to you, don't give up on your goals just yet.
This is often the result of changes in fluid balance, which means that your body retains different amounts of water at various times of the day. For instance, when you wake up in the morning and you haven't had anything to drink for several hours, you often weigh less than you do in the afternoon.
Exercising too much without resting enough in between can lead to low testosterone levels and high levels of cortisol, the stress hormone. These hormonal changes are often associated with loss of muscle tissue, weight gain, and excess belly fat.
So as you lose weight, your metabolism declines, causing you to burn fewer calories than you did at your heavier weight. Your slower metabolism will slow your weight loss, even if you eat the same number of calories that helped you lose weight. When the calories you burn equal the calories you eat, you reach a plateau.
You will not gain weight from eating too few calories.
There are many reasons why it can seem like under-eating can lead to weight gain. But, science has shown over and over again that this isn't physiologically possible.
"If you do a moderate-high intensity workout without properly fueling, your blood sugar can drop very low, making you feel dizzy or faint," Matheny explains. You're also likely to feel straight-up tired or lethargic if you're not giving your body energy, yet are demanding a lot from it during a tough workout.
Skipping breakfast and other meals is one behavior studied as a factor influencing weight outcomes and dietary quality. Based on evidence that skipping breakfast reduces total daily caloric intake, some weight-loss recommendations include skipping breakfast (i.e., intermediate fasting) as one strategy to use.
Typically from the age of 40, testosterone levels drop. As testosterone is responsible for regulating fat distribution, muscle strength and muscle mass, less testosterone can make it harder to burn calories. Both men and women produce less growth hormone from middle age, another hormone involved in regulating body fat.
You're putting your whole heart and soul into the fitness regimen, going to the gym five days each week. You should be able to notice visible changes after about two weeks of training 5 days a week.
Within three to six months, an individual can see a 25 to 100% improvement in their muscular fitness – providing a regular resistance program is followed. Most of the early gains in strength are the result of the neuromuscular connections learning how to produce movement.
