Your body will generally hold on to an extra 5-10 pounds above your pre-pregnancy weight, until several weeks after weaning and this is to protect your ability to produce milk, in case of illnesses or famine/severe calorie restriction, which is often seen in fad diets.
Some mothers tend to gain weight after the WHO-recommended, six-month exclusive breastfeeding period. “Once her baby starts complementary feeds, the calories expended by the mother reduce but her appetite is still ravenous because her stomach size has expanded,” says Dr. Joshi.
Thanks to biological and behavioral changes, it's totally normal to gain weight when you stop breastfeeding. "It's really common that women will stop breastfeeding and their weight goes up," G.

Breastfeeding mamas who find themselves constantly hungry, while also gaining weight are most likely experiencing some issues with blood sugar, a response to hormone levels - specifically prolactin, and a response to lack of sleep.
Both oxytocin and prolactin contribute to feelings of calm, love, relaxation, closeness and contentment. As breastfeeding ends, both prolactin and oxytocin levels will lower – and so may your mood and sense of wellbeing. It may last a few days, or it may go on for longer.
There have been numerous studies on breastfeeding and weight change, though the results are inconclusive. Many factors, such as pre-pregnancy weight, diet and physical activity level, could impact weight loss after giving birth. On average, exclusively breastfeeding mothers may see a loss of 1 to 2 pounds per month.
Your Hormones
Prolactin is the hormone that tells your body to make milk (2). It will also increase your appetite. This increase may cause you to eat more calories than you need for milk production. Those extra calories could cause you to gain weight instead of losing it.
The truth is that breastfeeding doesn't affect breast shape or volume. Instead, the ligaments that support a woman's breasts stretch as breasts get heavier during pregnancy. After pregnancy, even if a woman doesn't breastfeed, this stretching of the ligaments might contribute to sagging breasts.
Overall maternal adaptations during lactation include increased basal metabolic rates and mobilization of fat stores [22–24]. Maternal fuel metabolism is altered markedly, with a 15 %–25 % increase in energy expenditure for milk production [24, 25].
Postpartum weight gain can happen for a number of reasons, from the fact that you're fatigued or don't have time for a regular excercise routine, or because of an underlying health condition that requires attention, such as postpartum thyroiditis, diabetes, or PCOS (polycystic ovary syndrome).

While breastfeeding burns about 500-700 calories extra per day to fuel milk making, this may not always contribute to weight loss postpartum – many factors like pre-pregnancy weight, diet, physical activity level, etc will impact weight loss after birth (Institute of Medicine, 2002; Dewey, 1994).

Eat at least 1500-1800 calories per day
While nursing, you should not consume less than 1500-1800 calories per day, and most women should stay at the high end of this range. Some mothers will require much more than this, but studies show that going below this number may put supply at risk.
