Absolutely! I’m actually on a diet right now and I’ve lost around 10-11 lbs. within the past month. What’s I’m doing is a low-carb diet and counting my macros. Macros (macronutrients) consist of carbohydrates, protein, and fats. I’l link you to a really good guide on how to do that here. You can count your calories as well, though counting macros is much more important and usually when you hit your macro goals you’ll also hit your calorie goal at the same time. Another thing that’s super helpful in keeping track of what you put into your body is to keep a diary; there are plenty of apps out there, but my personal favorite is MyFitnessPal. All you have to do is search for what you ate, add it to your daily diary, and it gives you all the nutritional info without any extra work on your part.
Check your weight every week, at the same time. If you want to get the lowest weight possible, go to the bathroom to lose weight from water and waste lol. If you really want to, you can weigh yourself everyday, though I would not recommend it because then the diet becomes less about being healthy and more about obsessing over your weight.
As for the low-carb diet, I’ve lowered the amount of carbs I’m eating to 15-20% of my daily intake, and increased the amount of fats to 45%, while keeping protein at around 30-35%. I’m doing a keto or ketosis diet, where your body burns fat instead of glucose and doesn’t need to release insulin (therefore getting rid of all the crappy side effects when insulin is released and leading to higher energy overall). A super helpful guide to the keto diet can be found here. Don’t forget to drink LOTS of water if you choose to go this route.
I highly recommend checking out low-carb/keto communities around the internet, especially those on reddit, for all sorts of delicious recipes and helpful tips.
Another thing I feel like everyone should do, even if they’re not planning to go on a diet, is to either read the book Fed Up or watch the documentary. (I’ve placed a link to the movie) When you’re eating healthier, make sure that you’re not going to be tempted by unhealthy foods, and always, always fully check nutrition labels and compare them side-by-side when you’re going grocery shopping. Be ultra careful when you’re eating out as well, and pay attention to portion sizes. You also want to know exactly how much food/nutrients you’re putting into your body, so you should measure out everything before you eat it. You can estimate sizes/weights if you feel like getting a meat weight is overkill lol (personally I have one and I feel like it helps out a lot)
And about exercise in relation to diet: you really don’t have to exercise as long as you’re keeping your food intake in check. Cardio is pretty pointless unless you’re an athlete, but strength training is a good idea, and will help you out in the future as well. (Although of course, you don’t need to do these things if you don’t want to)
If you couldn’t tell already I’m kind of obsessive about nutrition hahaha
But good luck to anyone going on a diet/currently on a diet! A diet should be about changing your lifestyle. If you’re going to eat junk food with empty carbs and a piece of lettuce to “balance it out”, then you’re not ready to diet, and if you think you’re going to lose weight this way then you’re delusional.
Remember the internet is your best friend and you can find tons of great tips if you do some searching!
