Search Results: what are his real intentions

Just a side note: It's been a solid year since I've been in any kind of relationship, so my perceptions and judgement are rusty. Don't judge me too hard :/

This guy I've been messaging with for two weeks has been one I've really enjoyed getting to know. We had a date planned this week, and he kept on about how excited he was and how he wished we could meet sooner. But my last text from him was yesterday (Sat) around 7pm (it's now almost 11pm (Sun). I can't tell if he's just busy or taking the day to himself... or if he's lost interest in me. Our conversations were so upbeat and he sounded like he was enjoying talking to me just as much, if not more than I was enjoying talking and planning dates with him. He's been very honest with me about his intentions on wanting to find a real relationship and how he's dating because he can see a future with the girl he's dating. I've already gotten to know a lot about him, so I can't decide if I'm just overthinking things or if the spark on his end just went away all of a sudden

Common knowledge tells us that when we eat more calories than we need, we gain weight; and if we eat less calories than we need, we lose weight. But I wonder what happens if less emphasis is put on the weight or number on the scale and more emphasis is put on the body composition and fat distribution.

Let's take a 250-pound, 6'2'' man. He is the archetypical fat guy, eating too many high-calorie, low-nutrient food products. But one day, he decides, out of the blue, that he just does not want to eat junk food anymore. He wants something new for a change and tries to shop for some cheap, healthy food products at his local supermarkets. He makes sure that his diet is balanced and enough to build muscle through intense resistence-training. Riding a real bicycle can be a form of aerobic, cardiovascular exercise as well as a form of resistence-training (especially if you are trying to ride upslope). To train his upper body strength cheaply, he does bodyweight exercises and educates himself on proper form to avoid injury. His goal is not to lose weight, but to change his body composition, so that he has more muscle than fat, while remaining at the same weight. So, he continues to eat at a calorie surplus, but this time, with good food to supply the growth of muscles. He hopes to remain a big guy, but with more muscles than fat.

Which method do you think works best? Do you think people should eat at a calorie deficit to lose weight, or do you think people should eat at the weight-maintenance level or at a calorie surplus with the intention of changing the body composition especially in regards to building more muscle through weight-lifting, bodyweight exercises, and resistance-training in aerobic exercises?
