So you've really been trying hard to get in daily exercise and eat as healthy as possible but yet you're still not losing weight like you thought you would be. Don't give up, your new routine may not be at fault. WebMD outlined some interesting (and lesser known) reasons you may be gaining and not losing weight, and they may surprise you. Here are highlights:
- You Might Be Gaining Weight Because of Lack of Sleep: The body functions best when well rested. "When you don't get enough sleep, your body experiences physiological stress and, biochemically, you store fat more efficiently," says Michelle May, MD, author of Am I Hungry? What to Do When Diets Don't Work.
- You May Be Gaining Weight Because of Stress: "Stress response, whether it is 'fight-or-flight,' juggling too many responsibilities, or coping with financial pressures, triggers a biochemical process where our bodies go into survival mode," explains May. "Our bodies store fuel, slow down metabolism, and dump out chemicals [cortisol, leptin, and other hormones] which are more likely to cause . . . obesity in the abdominal region."
There's three more reasons so read more.
- You May Be Gaining Weight Because of Medications: Some prescription drugs used to treat depression, mood disorders, seizures, migraines, blood pressure, and diabetes can cause weight gain, from a modest amount to as much as 10 pounds per month. Some steroids, hormone replacement therapy, and even oral contraceptives may also cause gradual weight creep. Your medicine cabinet might be the cause of your weight gain if you've gained 5 or more pounds in a month without a change in your lifestyle.
- You May Be Gaining Weight Because of a Medical Condition: The most common medical condition that causes weight gain is hypothyroidism. A deficiency of thyroid hormone can decrease metabolism, causing appetite loss and weight gain. Much rarer is a condition known as Cushing's syndrome — a disorder caused by an excess of the hormone cortisol — that can also result in weight gain.
- You May Be Gaining Weight Because of Menopause: Women reach menopause at a range of ages, but most are in midlife and are often less physically active than when they were younger. Along with aging comes a natural slowing of metabolism. At the same time, hormonal changes can trigger hunger, depression, and poor sleep.

I wouldn't be too surprised if stress and lack of sleep were contributing to this for me.
1i have 4/5 of those soooo that's no good!
2My thyroid, but that I take meds for. Actually need another blood draw as I've been having symptoms again. The sleep thing is what gets me. UGH! I've gotten NO sleep lately and at least maintained, but when you are on a mission it's really irksome to plateau like that. BOO! I've been stuck at 174 (I'm not afraid to say my weight anymore) for ages. Guess I just need more sleep!
3Great. The only one that fits me is #4 - Medical Condition.
4I feel you kiddylnd, I've lost 18 lbs so far and I'm stuck at 164 for almost 3 weeks! I generally sleep okay, but I stress a lot over money. I'm also extremely lonely and sad a lot, so I'm sure that's not helping at all. Today is my off day, I think I'll go to the dog park
5I want to go to a doctor and get my thyroid checked out. I've been working my butt off in the gym (strength training) and outdoors (cyling, running, softball) on a daily basis for the past three months, and I have only lost 5.5 lbs these last THREE months. I don't get it. I haven't increased my food intake, and I try to eat as healthy as possible (avoiding processed foods, sugary things, foods containing lots of sodium, etc.) It is really frustrating because others would have lost at least 10+ lbs with all the working out I do in that time period!!!
6i gained so much on the pill that i went off of it. i was constantly hungry, i couldnt stop eating. it was horrible.
7Interesting, I am on a continual dose of Elavil for Migraine management...plus I work alot of night shifts, which is horrible for the diet. I work out daily but the weight creeps of ever so slowly..
8My birth control has a weird form of progesterone in it that makes me bloat up like crazy. It's not a big deal, because it's just water weight, but it's kind of annoying. I may look into getting a different pill that doesn't make me retain water as much.
9Numbers 1 & 2: no thanks to university.
10I gained weight because I started to eat soy products to lose weight...and then it turned out I have a soy allergy!
11LACK OF SLEEP + STRESS + BIRTH CONTROL makes me fat, I guess. Also, the cake I eat every day.
12I'm with julibul. But I don't think the ice cream helps either. I think it is important to know these potential reasons so we can be less self-critical, but it is also important not to let them become excuses!
13Also, you can't fight your body. Everyone is different. Everyone has a different bodytype. I've been the same weight for years regardless of the fact that I completely changed my diet to eradicate processed and fast foods two years ago. I saw absolutely no change in my weight or body. But I know that I am healthier inside so I keep it up. Instead of fighting with my body to change it, I just accept the fact that this is how I am supposed to be. This is me.
14All these might be the case, but one reason is missing... wrong diet for your body... or that cake you just downed. I def gain because lack of sleep!
15Very interesting. I definitely agree with the lack of sleep one.
16"also the cake i eat every day." that made me laugh out loud!
17Definitely those damn migraine meds. Mine were switched, and I have gained 20 lbs in 7 weeks, and I haven't changed what (or how much) I eat and I've been going to the gym MORE to try to combat it. I am not pleased. But I guess I'd rather be fat than have frequent migraines...
18I think I just need to work out more regularly; I have a tendency to let other things get in the way, especially if I've lost weight recently. I end up figuring I can skip one session, which becomes 1 week and then 2 and then i wonder why I'm gaining weight! Also getting off antidepressants and mood stabilizers 2 months ago; I love that I can control my sleep better now, but I definitely feel more stressed, although ironically less depressed much of the time.
19I agree with TidalWave on not being able to fight your body. I'm pretty much genetically predisposed to pack on extra weight. Even when I was playing soccer, working out 3 hours a day for six days/week for four months, I never got to my goal weight or goal look. However, I felt good, was more toned, and could run a 6 minute mile.
20How about I'm eating a liiiiiiiiiittle bit more than I was a month ago. I'm changing that as we speak though. I haven't gained any, but I'm not losing anymore even though I'm varying my workout.
21mine is the stress one. college=stressful!
22oh no!! oral contraceptives is on that list too
((
23Stress and sleep would be my issue...
24I think stress is always an issue b/c it always makes you feel as if working out is the last thing you have time for. At least, that's my experience!
25hypothyroidism, woo!
