Disappointed in myself

At supper are you splurging evey night? Eating what everyone else is eating and snacking after supper? I did have this problem same as you losing and gaining over and over what i noticed that helped me is I started using a smaller plate "kid size" I eat a small amount of what everyone else is eating or I try and make it healthier. For example lastnight I made my husband homemade pizza lods of meats and cheese.. for me I used a pita bread 150 cals and measured out my cheese and tomato sauce and topped it with veggies. Last week I made spagetti for my husband. I used spaghetti squash and lots of mushroons in my sauce. He had typical noodles, meat, cheese and garlic bread.. dont be too hard on yourself. Just make easy swaps or enjoy what you want but smaller portions

If you're blowing it at night, maybe you're not eating enough during the day? Try to space out your meals and snacks to a little later in the day. If it's a matter of you just splurging or eating what every one else is eating just because then it's a matter of discipline and will power. Using a smaller plate as suggested by the person above me helps. Also, try setting out your portions and putting the left overs away before you even begin to eat. After dinner, close the kitchen. I don't know what you are eating but try eating foods that are low calorie but extremely nutrient dense... use a ton of vegetables, they are healthy and filling and low calorie.

But I also know there is a difference between being full and just having a craving... it's a hard habit to break. You've got to figure out the root cause of you "blowing it". Boredom, stress, tired, thirsty... once you figure that out you'll be able to solve the rest of it.
