Good luck to you all. You are working a plan to, most likely, live longer and in better health. One way I have always controlled my weight is by weighing on the scale every morning. If I am up one pound, even, I cut down that day on things that add the pounds. Usually no bread for a day. No foods with sugar in them. Some weight loss experts advocate daily weighing and others don't. It has worked for me for years.
One way to control cravings for sugar is to chew sugarless gum.
Extra is the brand I used when being on the Atkins Diet for short periods of time. No longer than a week or two. One doesn't have to exercise on that diet. The pounds fall off, if you strictly adhere. The only craving will be sugar. I like the diet once in a while because it includes fatty foods I rarely eat ,and it sans anything with sugar.
Even though weighing oneself every day can show fluctuations in weight due to water, I still back off that day of anything that adds pounds and as always, I do keep portions small.
I do exercise but when on Atkins, I didn't and 5 lbs gone in 5 days. ( mostly water ) When resuming regular diet, 2 lbs hop right back on. But I never gained more than 3 pounds so it worked out perfectly. Now, I won't even let myself gain that much.
Will power! You have to love life and health, i.e., yourself, more than you love food. One has to go.
Loads of luck to you.
