When got only so much left

Also consider what you had for breakfast and how it affected the rest of your day. If you ate mostly carbs and sugar did it leave you feeling hungry later? That might be the better reason to adjust to eat something slightly different in the morning. If your breakfast was mostly fruit based (which mfp will still count as all carbs and sugar) you may find that fills you up because it is bulky high volume food with few calories (assuming you eat it whole rather than drink it as a sweetened juice). A sugary baked donut or french toast or pancakes with syrup may have the opposite effect - lots of calories and sugar, little fibre, quick energy crash after the sugar wears off that leaves you hungry for more. Either of those two breakfasts could be improved to suit your personal needs once you see how you feel. If you are eating lots of low calorie fruit (that nevertheless has lots of carbs and sugar) add in a serving of greek yogurt or cottage cheese or an egg to get more protein, a bit of fat and longer satiety. If you are eating lots of sugary, processed carbs, try switching half of them out for something like fruit and/or yogurt or try something less sugary that still has carbs like a high fiber toast with smoked salmon or avocado, or even fibre toast with a bit of cream cheese and all fruit jam. Or eat something else you like at other times of the day for breakfast. There is no need to eat traditional breakfast foods in the morning if they are tough to work in to your nutrition plan and you don’t otherwise crave them.
Finally check what the mfp nutrition entry is against the package nutrition label. Many mfp entries are way off especially on macros. Correct incorrect entries for stuff you use and save them in your recent or frequent foods list so you can find them again.
And if you aren’t already weighing everything on a digital scale do so - that changes a lot of values especially when working in a low calorie range like 1200.
