Sticking to calorie deficits

two options:
- portion out your sweet for that day' to fit in your calorie goal. stick to that. buying things that come in portion control packages can help. take out your portion (weigh it out) then put the item away. if you have a freezer in basement use that one to store ice cream.
- for the first while if you are unable to stop, get these items out of the house. you can find "safer" alternatives you can control yourself better with. at least for the first while. once you practice good habits you can try bringing them in. I used things like fudgycles and jello-o cups for the first while until I was able to work UP TO having bars of good quality chocolate in the house and EAT ONLY ONE SQUARE. but it was a few months before i got there. Ditto with ice cream (which i don't bother with much other than the low cal ice cream as it's a calorie killer and "special occastion" thing). I will go buy one fancy cookie at the bakery VS box of cookies.

I found that since I’ve shifted what times I eat, I can avoid hunger later in the day. I’ll have breakfast, lunch, a snack after school and then dinner at maybe 7-8pm and this tends to be enough for me. You should adjust it to when you feel most hungry so you’re not as likely to snack.

Finding healthy alternatives to your favourite snack foods also works- Like low fat/sugar ice cream, low cal cookies. Ultimately you WILL feel some level of hunger if you’re used to eating large amounts of food, until you get used to sticking to the calorie count you’re given- There’s always an adjustment period.

My best advice is to log all your food in the morning (or night before), making sure to add sweets for the end of the day as well. When you do it like that, you see what you can fit in within those calories. Also remember if you exercise, you can eat a little more on those days.

Success with a regular caloric deficit comes from planning. If you mean prep at the beginning of the week you can pre count the calorie amount in those meals boxes. High protein, high fiber and low fat will give you a more full feeling for longer.

At night I also like something sweet or I just feel like I need to eat a little something in general. Often times I can drink a cup of organic juice that is naturally sweet and it fulfills my need. 😋👍🏻

I still have to learn a lot about portion control. So I checked my MFP record over the last 11 months and set myself calories per meal time. I am not a big breakfast fan - and keep my calories on around 250. Lunch - I never have much time, so I try to stay within 450 calories. Dinner - the family meal around the table - was always a calorie problem for me. I give myself about 750 calories and snacks (I am not a "snacky" person) 300 calories. Total 1750 calories per day. With exercise I eat a little bit more. This calorie split helps me to work out a basic meal plan for the next day, also including other eventualities like eating out. It might sound cumbersome, but I am used to it now and it works for me.

Are you sure 1600 calories is appropriate? I’m 143lbs and losing, albeit slowly, on 1550.
I found that when I increased my protein, I am much less hungry throughout the day. I still save some room for something sweet at night.
