First, ditch the idea that formula is "so much better for babies that it is close to the same as breast milk." That's hogwash.
Second, breastfeeding HELPS you lose weight. Geez, you obviously haven't done any research on this.
"Formula is an artificial substance that is made to replicate mother's milk. It is NOT a duplicate of mother's milk. Pick up a can of formula and read the ingredients to see that it is quite inferior to breastmilk. It is mainly made up of sugar and oils and a protein such as cow's milk, soy or whey. It does not contain antibodies, digestive enzymes, or immunoglobulin. Babies that are fed formula are 14 times more likely to be hospitalized in their first year. These babies are more prone to respiratory illnesses, ear infections and diarrhea. Babies that are fed formula instead of breastmilk miss out on the intense physical bond that allows them to develop a sense of trust in the world. Giving your baby formula is not the same as breastfeeding. Formula is not an equal substitute for breastmilk. It can keep alive a baby that has no access to breastmilk but is actually fourth on the list of best food choices for baby. The first three being breastmilk from the mother's breast, breastmilk pumped and given in a bottle and then another mother's milk from a milk bank."

"What Breastmilk Has That Formulas Don't
Why breastmilk will always be better than formula.
Formula feeding is the longest lasting uncontrolled experiment lacking
informed consent in the history of medicine."
— Frank Oski, MD

Protection against infection
Children who are formula fed are at significant risk for infection. We have just come to accept that infants get RSV, rotavirus and ear infections. They are not supposed to be diseases of infants, but in the USA, the largest consumer of formulas world wide, we hospitalize many, many, many infants each winter with those diseases. The great majority of those infants are formula fed.
In fact, the number one risk factor for kids getting ear infections is bottle feeding: not day care, not smoke exposure, but formulas. Think about the loss of work, the exposure to antibiotics, the midnight purchases of medicine for fever and rehydration solutions, and visits to me that could be avoided if more families chose to breastfeed their infants.
You see, infection fighting cells of the body are present in abundance in breastmilk and are not found at all in formula. So children who are formula fed are not just at risk for ear infections but diarrhea (from rotavirus, E .Coli, cholera, Giardia), and respiratory infections (like RSV, influenza, H. flu, pneumococcus). Plus, formula fed kids get more meningitis (From H.flu, pneumococcus, herpes, and group B strep).
Protection against inflammation
The factors in breastmilk protect premature infants from a potentially fatal gut complication called necrotizing enterocolitis (NEC). Children born at 30 weeks of gestation have a 6-10 fold increase in their risk for NEC if they are formula fed.
Protection against Cancer
A study done inn 2002 showed that for every 12 months a mom breastfeeds, her risk of breast cancer decreases 4.3% as compared to women who never nursed. Another showed a 54% reduction for women who breastfed for greater than 24 months.
A study in 1999 looked at the risk of leukemia for kids who had never been breastfed versus those who were. Children who were breastfed had a 21% reduction in risk of childhood leukemia. Said another way, children who are never breastfed are at greater risk for leukemia than their breastfed counterparts.
Protection against lifetime illnesses
Breastfed kids have less obesity as they enter kindergarten. They are 26 times less likely to develop insulin dependent diabetes. Formula fed kids are at higher risk of developing eczema.
A consistent recipe
Breastmilk has had the same recipe for many, many, many years. It hasn't needed a fan fare of advertising for every new ingredient change, because the ingredients haven't needed to change. The celebrating that formula companies do about the improvements in their product are really what happens when a deficit is fixed. Formula companies realized that their product needed to be fortified with vitamin D when kids started having seizures from low calcium levels. They tried to help combat adult high blood pressure problems with a type of formula low in sodium until kids started having seizures from low sodium levels. When there wasn't enough iron in their product, they found out after many kids became anemic, and that iron-deficiency anemia, as we have learned, has had developmental consequences. Plus, formulas in powder form have the potential to be contaminated with bacteria. The ready-to-feed and concentrate are sterilized, but powders aren't. The great majority of formula recalls have been because powdered forms were contaminated with potentially harmful bacteria.
Other ingredients, found in breastmilk, are still missing...in the future, we may see other additions to formula like infection- fighting oligosaccharides, insulin, and prebiotics. That means that they are not in the recipe now.
So what if all the ingredients in breastmilk got in formula some day..
So let's say they get all the ingredients in breastmilk (all the white blood cells, antibodies, anti-inflammatory cells, and biologically active compounds that are so important to our children's' health in formula... would breastmilk still be better? Yes. Of course. The milk a mom makes for her baby is perfect for her child. Nobody else can ever make a more perfect food. The antibodies in a mom's milk are specific to the viruses and bacteria that mom and baby came into during that day. The composition of the milk varies from the beginning of the day to the end of the day, the beginning of the feeding to its end, changes to meet a growing baby's needs and is flavored with foods that mom ate, making every mouthful of food different, and perfect for that baby. No formula company can ever make a more perfect food for your baby than you can as that baby's mother"
