20 years old, 230lbs., 6'4" Male

I have been riding the stationary bike for 3 days in a row now since I just got a gym membership. I have been riding for 60 minutes putting out 200watts-250watts each workout so I would consider that to be a vigorous workout. The online calories burned calculators that I have found list that exercise as a 1200-1400 calories burned activity. I have been eating 2000 calories on those same days and I dont feel tired or hungry but my research puts me at a calorie deficit of 1500-2000 a day, depending on the website...

Can someone please tell me whether this is believable or not.

Its believable.Im in the same boat as you.I ride stationary for 60 minutes and average 900 Calories burned with generating 150 watts.I eat around 1500 Calories a day, and on average have a 1500 Calorie deficit a day, and i never feel tired or hungry.I just eat small meals 4 times a day and take whole food supplements.I do have one cheat meal per week, where i burn an extra 1000 Calories that day.I notice 2 days after a cheat meal, is where i drop 2-3 lbs that week.Strange

Anyone else out there experienced my current situation?

If so what were your results?

Does it really matter at this stage in the game, when I assume you are losing and not on a dreaded plateau? Are you losing 1 to 3 lbs per week? If so, then keep it up, if not then adjust your exercise or eating. Calories burned are normally calculated by your heart rate, so no matter what the machine says and the wattage etc, its all about the HR when it comes to aerobics (machines' cals burned numbers are known to be off by 20%). The higher your HR, generally the more calories you are burning. This doesn't necessarily apply to weight lifting however, where you are burning perhaps less calories during your actual workout, but plenty more post-workout when you're muscles are working to repair and grow.

"Calories in subtract Calories burn = Calories shortage" is NEVER a perfect math calculation inside the human body. Neither is "calories in subtract calories burn = calories surplus" situation either. Some how, the body adjusts to variances in the back ground. Especially during short time periods.

If your body is strong, can do the exercise and things are "feeling great" then, "keep doing what you are doing". That's what my doctor always tells me. (giant smile).
