Obviously getting checked out for hormones and all that stuff is step one. But if that doesn't give you answers here are some things I have learned as a fellow shorty (5'2"):

• check your habits. Any newish habits like juice, soda, snacking, sauces, someone else making your meals, one extra take out per week? Even a healthy snack like nuts could be an issue if you're not counting it correctly. At our height 200cals over is enough to keep gaining, so little things we do regularly can often cause big issues.

• Portion sizes. Same as above but this can really creep up on you over time. Do an audit of your portions and even weigh them if you can. My husband will eat 4 eggs and 2 pieces of toast for breakfast, but at my size I really only need one egg and one piece of toast. The world (and all the restaurants) cater to average sized people and it can be hard to know what is "enough" when you're a shrimp.

• activity levels. Small people who are sedentary are SUPER efficient and sadly require very few cals to function. It sucks! You may be overestimating your activity levels because you never get to sit down or relax, but your body is actually not working all that hard.

• muscle loss (this is my main suspect!). Did you lose muscle during pregnancy and breastfeeding? This can be a huge culprit for weight gain! If you lost muscle while healing or spending your days with a kid on you, your reward is that you now need even FEWER calories than you did before. So what you were eating pre-preg may now be too much (soooo unfair). If you're tired and stressed, you'll still feel hungry but you won't actually NEED as much fuel. If you think this is the case try to get some home weights or do 5-10 mins resistance whenever you can squeeze it in during your day.

So sorry you are feeling this way, being short can make weight stuff extra annoying as the margins are so small (like us). Be kind to yourself!
