If you pick-up a magazine, watch TV, or listen to the radio, you're bound to encounter an advertisement promoting a new diet and promising weight loss. Some of these may be based on sound nutritional practices, while others may be fads that come and go.
Search the Internet for information about a diet that you've heard of and want to learn more about. In your initial post state the name of the diet you're investigating, describe it, and explain why you think it would/wouldn't work.

Ketogenic diet (keto diet).

It’s a low-carb, high-fat diet which encourages the body to burn fats instead of carbohydrates.

It might not work if you don’t get the food proportions right. The person may not cut enough carbs out of their diet (they won’t lose weight).

It also doesn’t work for everyone (There is some explanation behind it but I don’t know it, sorry. However, you could say that just like other diets, it just doesn’t work for some people and their metabolism).

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
