Eating only protein bars?

[Anonymous]

What would happen if someone only ate protein bars for a week? 5 bars a day, each have 200 kcals, so 1000 calories a day, so there won't be a high calorie intake.

That depends on the protein bar...

The ones I eat have 170cal, 10g protein, 9g fat, 21g total carbs, and 1g of those carbs is a simple sugar--per bar. That's just about as good as a protein bar can get in terms of hitting macros with as few calories as possible.

However, in order to get all the macros I need and to reach maintenance calories, I'd need to eat 13.5 bars every day. Granted, you wouldn't need quite as much, especially since you aim to be in a deficit--but it would still cost a fortune. The amount of money you'd spend per month on food would match your rent.

Protein bars aside, 1000 calories per day is not healthy (unless you weigh 50lbs or less). Go here to find out your maintenance calories ("Total energy expenditure"): www.health-calc.com/.../energy-expenditure-advanced Subtract 25% from that number to find the absolute minimal calories you need in order to prevent your muscles from catabolizing (wasting away).

If you're serious about losing weight, eat about that many calories per day, and no less. You should also try to get the right amount of each macro, and if you'd like more info on how to do that, just ask.

Not much but you may feel weaker since you'll be deprived of essential nutrients from natural foods you consume.

Fun fact: Did you know protein comes from plants?

If you want to gain muscle, you're better off eating fruits and vegetables. Vegetables are low calorie, it takes calories to digest them and you get the protein you need directly from the source, as well as all the vitamins and minerals you need. Some fruits are higher calorie than others but they're mostly water so your body burns them up fast

That's not good for you, too much protein and little exercise can be bad for you. If you're trying to lose weight, go down the slimming world/weight watchers route, not eating protein bars, you'll be unwell.

You’ll lose a lot of weight in a bad way... you’ll have energy issues... constant cravings...
