Why am I gaining weight even when working out?
I just turned 19 a week ago and I’m 5’10 or 5’11″. Around the end of last year I weighed about 160-165. I started lifting weights and exercising seriously about 2 weeks ago. Now I weigh about 183 last time I checked. I regularly run on the track and do upper/lower body workouts. I’ve also been consuming much more whey protein to build muscle and have been eating healthy. I already had a large and well formed pectoral muscles before starting lifting again. I notice an increase in strength, although I don’t notice such a dramatic increase in muscle mass other than being more defined. I never eat junk food anymore like chocolate, ice cream, candy, pizza, etc. Sometimes I only have time to eat one real meal in the evening and a light breakfast. Therefore, I don’t see how my diet would be increasing my weight. Apart from lifting weights and running, I do abdominal workouts almost daily to hopefully get a six pack one day. I’m not that close yet, but I notice my top ab muscles when flexed.
You sort of answered your own question there friend. It’s muscle mass.
Muscle weighs more than fat
The answer is simple, muscle weighs more than fat. As you increase your muscle mass and reduce fat you will gain weight but it is lean muscle.
I would suggest that you eat a better breakfast and lunch then go light for dinner so you burn off the calories during the day when you need them.
Good for you.
