SP works... if you work hard at it There is no quick and easy way to lose weight... or at least no healthy quick way. It's simply a matter of eating fewer calories tha you are burning.
You're probably a busy person, perhaps with a family to look after and/or a very busy job, but unless you make your own health and fitness a priority, it isn't going to work.
Take time to plan at least some of your meals before grocery shopping. Plan to use left-overs for another meal rather than having a second helping. Avoid prepared, processed foods as much as possible - in most supermarkets, that means most of your purchases should be from the perimeter of the store, not the middle aisles.
Schedule in 3 healthy meals and 2 snacks (including an evening snack) every day. If you have children, don't clean up their plates (one of my bad habits when my children were young).
Schedule some exercise time for yourself, alone or with family or friends. It's can be as simple as a 10-minute walk around the block. Start with 10 minutes doing something that you enjoy, then build up until you are doing 30 minutes at least 3 times a week
If you are eating in the evening because you're bored, find a new hobby. If you eat because you're tired, maybe you should go to bed earlier. If you're frustrated or feeling low (emotional eating), try to figure out the real problem instead of going for the ice cream.
You really can do it, if you work hard. I hope you stick to it.
