for the heavier men

I hear it's around 10% body fat loss. But it can be more discouraging for people who have more to lose because it's harder to see changes. 10% is 30 lbs and even then it's not always noticeable to everyone. A lot of people don't notice because in their mind they still see a heavy person even though that person is getting smaller and smaller (maybe the change is too slow for some people to notice). Sometimes it takes a while for others to notice or even yourself to notice.

This one friend of mine lost 50 pounds. She looked great (she's still losing more, and looks even better now) and I did notice then, but I also hadn't seen her in several months. If I saw her every day or even once a week I'm not sure the changes would have been as noticeable.

I would focus on:

1. pounds lost. losing 30 lbs isn't easy, so good job!
2. inches lost. even if the scale stays the same or even goes up slightly, you will lose inches from working out as your fat turns into muscle.

Remember, slow and steady wins the race. It's much more difficult to lose a pound (3,500 calorie deficit) than to gain a pound (eating 3,500 calories can sometimes happen in a single meal at some restaurants). Every pound lost is a job well done... just make sure you find other ways to celebrate besides food or you'll gain it back.

I think you will notice more with smaller changes in weight if you are also lifting. I did not see you mention that in any of your post. I personally would recommend that if you already are not. Even lifting at a calorie deficit will be helpful as it will help retain muscle as you lose weight and when you drop BF it will help you look more defined.

Good Luck mane!
