【推荐2】How to Maintain a Healthy Body Weight

Our life is too much involved in work, earning money and eating junk food. Keeping the body in good shape should be the first priority in our daily schedule. Nutrition is a key factor, but our health depends not only on what nutrients we eat, but how much of those nutrients we absorb, and how well and how regularly the body’s waste products are eliminated.     1     Once these are in place, you can achieve your ideal shape.

Try not to eat too much junk food

    2     Eating lots of pizzas, burgers, and so on not only makes you feel lazy and increases your body fat, but it can also cause heart problems.

Eat healthily when you eat out

When you see these words on the menu, skip these items altogether or share them so that you can eat a smaller part: “fried”, “cream sauce”, “cheese” and “dipped”. Don’t give up on going out to eat. Simply learn how to do it the right way and get a sense of how many calories there are in what you are ordering.

【推荐3】Having a personal trainer is one of the best ways to stay on track with your workouts, push your limits and try new things. But it often costs more than $100 a class, and getting to and from the gym can take up a lot of time.

Over the past ten years, fitness apps have been trying to copy the personal training experience exactly, and in recent years many have included artificial intelligence (AI) to create workouts. A growing number of products offer personalized works that match your abilities, goals and equipment you have, which usually cost around $100 a year.

However, some experts warn that while AI fitness apps are useful for many exercisers, they’re not the right fit for everyone.

AI fitness apps create personalized training programs using information from personal users and the experiences of other users.

In the future, these apps could collect even more information to give ever more personalized feedback (反馈), said futurist David Brin. But, he added, more information doesn’t always lead to better advice. “What you need to consider is whether the advice will actually be good for you, in the long run,” he said.

Furthermore, computers can learn a lot about different workout routines, but they can’t yet create the social interactions that make the training successful, said Nikola Banovic, professor of computer science and engineering at the Artificial Intelligence Laboratory of the University of Michigan.

The AI fitness apps we have now can’t offer encouragement or provide comfort on a bad day. “As humans, we need more than just the workouts that will get us to our goals,” Dr Banovic said. “We need to be encouraged — that’s something only a real trainer can do right now. It will be some time before AI training does this well.”
