I'm expert so all I can tell you is how I have lost a fair bit of weight.
First I roughly calculated my base metabolic rate and subtracted 500kcal from it, I then changed my daily diet so that I always consumed near enough exactly that amount but spread over 5 small meals.
I also upped the amount of exercise I did per week but not overdo it.
As well as that , each day I would read about nutrition and about the human body, learning as I went along.
It worked great and I have lost a fair bit of weight. (although I have had a couple of hiccups because of ignorance such as stalling my weightloss through undereating )
6 weeks ago I changed to a cyclic keto diet, i'm still consuming the same amount of calories each day but now I eat a ratio of protein, fat & carbs, I'm still losing weight at about 1lb a week but most of it is fat.
I'm in good shape, I look a hell of a lot better, some old clothes fit me again and I feel great too

My father taught me all about that when I first took an interest.
I think there must be something in the water
