All useful for various reasons, but maybe indicating your weight might just trump them.
Like it’s been said already, start slow. Just get used to routinely moving. Walking is your friend. A colleague has lost (I kid you not) almost 50kg in 18 months from changing his diet and walking.
None of them can do much beyond weighing you accurately. They can tell you your BMI accurately, but the BMI is a very problematic barometer to be using.
All the body fat percentages stuff is pretty questionable - the way they work means you really only get information about your body fat percentage, muscle proportion etc as high as your waist, anything in the top half cannot be measured without additional electrodes being placed on the upper body.
However, the trends can still be useful to check in on, even if the absolute figures are likely to be pretty unreliable.
One of the diabetic research nurses at the hospital I go to said when the department got a DEXA machine the first thing each of the nurses did was to climb into it. Most of them turned out to be, um, on the plump side but she had a well below average body fat percentage. Then again she was an ultra-marathon runner. This was a pic she sent me of her running Oxford-Henley in the pee-ing rain along the Thames Path, about 75km I think
The amount of young guys I’ve come across who have wasted money on getting a Dexa scan because they’re frustrated with not reaching a six pack, when by eye or caliper they are clearly 15%+ body fat
