Losing too much weight from cycling

am estimating the calories I burned and eating to compensate but I'm still losing weight at an alarming rate. I'm a beginner and have a low end heavy bike. My speed is really slow. So even though the calorie calculators say slow speed =. less calorie, we have to take into account the type of bike? I don't even know if I'm cycling "vigorously" or "moderately" since I'm so slow. It's hard to say since I'm rather fit from running and cycling feels easier.

To get a connection between speed and calories burned, one must make an estimate of ride/riding conditions.
There’s room for huge error here.
A HRM, or a power meter on the bike is more accurate.
Failing that, try to compare duration and intensity with your running workouts.
I burn very close to the same calories regardless of activity as long as I keep the duration and effort level the same.
Bicycling IS easier in one aspect - low/no impact.
W/o the landing shock of each step, its kinder on the body.
Bicycling CAN be easier due to the ability to coast. Not only during the obvious descents, but you can also get tiny moments of rest only by letting up as dictated by the ride. Coasting through turns, letting up a little to speed match to traffic etc.
Overall your question makes me wonder.
Losing weight through exercise only is quite tricky.
The gap between rate-of-burn compared to how easy it is to overeat is simply too big.
Either you’re already on a very calorie balanced diet, or you’re riding your heart out for hours daily.

Have you been to see a doctor?

Seems strange, not sure what you consider "an alarming rate", but best to speak to a doctor, dietitian or someone specialized in sports medicine.
As mentioned above, so many factors to consider, but drastic weight loss, when you are not attempting to lose weight is cause for concern.

I agree with the others - see a Dr immediately. You should not be losing weight at an 'alarming rate' just from cycling.

as an RD this concerns me... if you were calorie balanced and didn't change anything when adding a ton of riding, maybe... otehrwise I agree- see a professional it sounds like something else is going on

"Losing too much weight from cycling" .... said no one, ever, seriously, unless they had major health issues.

If this is a real thread, lose the tapeworm. Otherwise ... whatever.

You want to bet? Some of us are "hard gainers". I retired from the Army and did no exercise except for cycling for three years. I got so skinny from the waist up it was embarrassing. Started taking mass gainer for an extra 1600cal/day and 5mg creatine/day along with a lifting program and went from 138 (I'm 5'10") to 170 in six months. Still rode as many miles and ate exactly the same. My daughter thought I was on steroids. My average speed didn't drop at all, if anything I'm a stronger climber now. Matter of fact, my all time 30 year personal best average speed solo came when I was 165 and 49 years old.

From my experience, it is possible to lose too much weight from cycling, but I know I have to be putting in a whole lot of cycling for that to happen.

On the flip side, I rode 325 miles a month in Nov & Dec to hit a milage goal, and I still gained 7 pounds during the holidays.

How much is too much? When I started I wasn't riding hard or very long distance, but I dropped 20 pounds in about 6 weeks from 160ish to 140ish. Not a huge amount, but it was apparently very visible as multiple people inquired about my health and advised me to see a doctor. Doctor said don't worry about it. I did lose more than an inch off my waistline and had to buy new pants.

More details would be helpful. How much did you weigh before and how much have you lost in how much time. Are you now underweight for your size? Do you feel healthy?

When I started riding regularly I lost about 15 pounds in about 5 months. Lost 3 inches off my waist and my wife said I was wasting away. After that initial period, I stopped losing weight and have basically stayed the same over the last year or so.

If you are concerned about it, go see a doctor.

Clarification: If a person loses Fat from cycling .... Great.

If a person loses muscle ... that is not from Cycling, per se, it is from poor nutrition and bad exercise planning.

For instance, if you stop doing upper-body exercise, yes, your muscles will shrink to whatever size you actually need---which has Nothing to do with cycling. That is your body being efficient---it won't spend calories producing muscle tissue you are not using.

If, say, you go on a long tour and do no upper body exercises and also eat a low-protein diet for a while, then your body will literally eat your arms and chest ... but that is not Cycling, that is a combination of not using the muscle and not eating right. I lost a lot of weight that way on one tour .... but that was a choice. I could have done a ton of opush-ups every night after riding, and I could have eaten enough protein to sustain th
The idea that riding a bike will make you lose muscle is just wrong. Muscle grows where it is used---ride a lot and your legs will grow. Sprint a lot and you will get big legs. Spin a lot and you won't grow much muscle mass, but the muscle will be very well serviced by blood vessels.

If a person is exercising and losing muscles which he or she is exercising .... that is a Serious medical issue, some kind of wasting disease. See a doctor, right away.

If aa person lets his or her upper body shrink and blames cycling when in fact it is just a stopped exercise regimen ... whatever.

The fact that Mr. Unmotivated Buttocks was able to gain back all that weight whole still riding perfectly illustrates my point. If cyclign was the cause fo the weight loss and he kept cycling, he wouldn't have been able to gain back the lost muscle.

In fact, inactivity was causing the muscle not be replaced when its individual cells naturally aged and died. And, if, on top of that, he wasn't eating enough protein, his body could have well used the otherwise unused muscle as fuel.

That's my story, and I will change it at will and deny every changing it.

+1
I lost nearly a pound a day during MTB touring in the Pyrenees.
But that was, in terms of effort and duration, frankly ridiculous.
My HRM logged 8000+calories/day.
Canít really see that being compatible with regular life.

I want whatever the OP is having. I ride 200 miles a week, and according to the data from the PM and calorie intake estimates, I'm averaging over 4,000kcal a day just to maintain my weight. Eat less and I would lose weight, presumably. But food is so good.

I'm worried that your beer consumption is inadequate.

I drank my 20's away. It never made me gain a pound of weight. Thankfully I outgrew alcohol.
