Everyone has different health goals. While some may want to lose a few pounds, others may want to bulk up a bit.
And there are some who are focused on losing weight and more focused on building muscle.
If you are thinking about shedding some body fat there is a lot or confusing advice out there.
There are countless eye-catching things out there, but the supposed science behind is questionable, and some are even a risk to your health.
Here are the best things to lose weight in a healthy way – according to NHS experts:
Drink more water and less alcohol
Many people think they are hungry when they are actually just thirsty.
So drinking more water during the day can help you stop eating extra calories.
Alcohol also contains more calories than many people, including wine and spirits.
Two glasses of wine are a citizen – and you would need to run for half an hour to burn it off.
Eat these high-fiber foods
Try to eat more high-fiber foods, as they help you to stay feeling full.
You can find fiber in fruit and veg, wholegrain bread, pasta, brown rice, beans, peas, lentils and oats.
Do not ban any foods
Some advice is banning certain foods altogether, but experts warn against this.
The NHS Choices website says: "Do not ban any foods from your weight loss plan, especially the ones you like. Banning foods will only make you crave them more.
"There's no reason you can not enjoy the daily calorie allowance."
Add more fruit and veg into your day
This sounds obvious but is essential for both cutting calories and staying healthy.
Fruit and veg are not only low in calories and fat, but also high in fiber – both of which are vital in losing weight.
You could try adding a chopped banana or handful or berries to your cereal or yogurt, have grilled or fried mushrooms or tomatoes with your eggs or have an unsweetened 100% fruit smoothie.
For lunch you could add lettuce, tomato or cucumber to your sandwiches, and have cucumber, pepper or carrot sticks with a dip or fruit for a snack.
For tea you could add salad, peas, carrots, broccoli or corn on the cob to your plate.
Eat regularly and stop snacking
Health chiefs say at regular times.
It also makes you less likely to snack, and cave in the chocolate bar.
You could also plan your meals for the week or have a weekly shopping list, so that you can buy unhealthy snacks or meals.
Find a simple way of doing more exercise
Being active is not a cut through your diet alone.
Tips include setting a time in the week and sticking to it, doing something like swimming or sports in the park with your child.

Learn to read food labels
Most products now have food labels showing how many calories, fats and other ingredients they contain.
Cutting down on high-caloric and other unhealthy products can really help – and the NHS has a helpful guide to what food labels actually mean.
