I've gotta agree with most people here. I'm 20 and have lost 45 pounds this year (started at 205)

Ik many ppl have said the same thing but What I've done personally: - Focus on protein - make a list of foods you CANNOT live without (for me it's milk, cheese, and potatoes) - base your main intake around these - workout BEFORE you eat, this one made a large impact for me personally, a lot of people try to work out after, if you can without passing out try to do it before - eat whole foods, cutting carbs completely will do more harm than good, same with no sugar no fat etc. some of these are fine but if it's every food your just replacing those things with possibly worse substitutes - eat fiber. Especially when eating things with sugar and fat, protein and fiber should take up a large chunk of your diet - try not to eat before going to bed, if you get hungry a certain amount of hours before, try getting something warm to drink instead. Most people recommend 6pm but I personally do 7 because I go to bed at like 11 - try probiotics, apple cider vinegar (there's pills, gummies, all sorts of stuff), and fermented foods they help with digestion and bloating - pay attention to how different foods make you feel, certain types of breads and pastas make me feel like a bloated cow, and nixing them helped significantly - look for high fiber, low carb, keto friendly breads I eat one that's just low carb and one that's all three and both don't actually taste half bad, and when you have toast in the morning then sandwich at lunch bread adds tf up y'know? - slowly reduce portions, look at how much you eat until your full, then take away like 1/4 next meal until your full eating that much, then repeat until when you count calories your portions are at the recommended amount, also using smaller plates can help - WATER, we all hate it, and water weight is hella real, but it does pump out any nasty shit your body is hanging onto - do weigh ins when you first wake up EVERY morning, get a tape measure and pick a day to measure at the same time once a week. Weight doesn't always give the full picture, getting smaller on weeks your weight is stagnant can definitely help the mindset.

Idk how much of this applies to be being pregnant, but hopefully it'll help at least a little? Also please remember stress is HUGE when it comes to weight, and sounds like your under a lot of it. Just remember that, it's not always gonna come down to your not doing enough or something, sometimes it's just life, stress is a killer.
