21 Zero Calorie Foods For Fast Weight Loss

zero calorie foods for fast weigh loss

If you’re looking to lose weight, but need to eat more to stave off hunger, simply fill up at meal times using foods from our list of 21 Zero Calorie Foods For Fast Weight Loss. You can use them to snack on too in order to keep you on track without ruining your weight loss regime.

What do we actually mean by ‘Zero Calorie Foods’?

Well, it doesn’t strictly mean that the food contains no calories at all. What it does mean is that the amount of energy (calories) used up in eating and digesting the food, is greater than the amount of energy in the food item itself. Thus resulting in the term zero, or in some cases negative, calorie foods.

Caveat: Beware foods that have huge amounts of artificial sweetener in them, but marked as ‘zero calories’, or ‘Zero Sugar’. So please don’t think you can drink unlimited amounts of Pepsi Max or Diet Coke, as I’m afraid you can’t! Sorry.

All of the foods listed below have less than 55 calories per 100g (3.5 ounces)

21 Zero Calorie Foods For Fast Weight Loss

FRUITS

In general, fruits tend to have more calories than vegetables, due to their high natural sugar content. But fruits do provide a flavour that is pleasant to eat on its own, or that can be added to used to other food items for additional flavouring too.

Apples

Apples are an extremely healthy fruit, full of antioxidants, vitamins, minerals, and fibre. There is also a reasonable amount of pectin in apples, which has been shown to reduce food cravings and hunger.

Due to their ability to stave off hunger and cravings, apples also make a great snack to enjoy between meals. They can make all the difference when trying to lose weight as they can tide you over, and prevent you from succumbing to junk food in a moment of weakness.

They’re also rich in phytonutrients — plant-based compounds that may help to lower inflammation and reduce the risk of developing cancer.

Broccoli

Broccoli is one of those foods classed as a super-food. It is a great source of vitamin C, K and D. The later is very good news as a vast proportion of the population is often deficient in vitamin D. It is also a good source of plant protein.

Broccoli has the ability to fight the risk of cancer, and is packed with phytonutrients and fibre, which help maintain a healthy digestive system. It can also aid in detoxifying the body and lowering inflammation. Broccoli is best if it is steamed or roasted. Boiling it too much can cause a lot of the nutrients to leak into the pan water.
