Hi

I began losing weight by setting out bowls of Healthy

'sliced foods' to snack/graze on day & night: apples, carrots, broccoli, berries, etc. Protein to toss in, setting on top of a green salad I make the evening before; I have absolutely No excuses to eat Stupid snacks anymore, I have a plate conveniently in 2 rooms. My energy & muscles have improved to.
I printed out a calorie/fat chart saying what exercise activity & how long it would take a active person to do to burn up the food. I'm +50 yrs & I don't exercise daily, I'm happy to get 3 miles daily on my Fitbit & lift handweights & on the weekends to use my kayak & go stand-up paddle boarding.
I substitute healthy ingredients & use a recipe for pre-packaged boxed store foods & use half the salt, etc. I cook & bake very similar just Healthier.
W.Watchers has a very good points system, I bought their shopping food points guide book with a eating-out point guide included when I attended a free meeting to see their plan. I don't have the time or $ to weekly weigh-in, so I didn't join. But the points book is a good guide when buying food ingredients & packaged foods & eating out.
I hope that something I do is helpful to someone here. I'm happier with my body & my life since I began these food changes
