When you undertake a weight loss program, you are particularly concerned about the caloric intake of your foods. Besides, you are constantly calculating the calories ingested. Did you know that there are negative calorie foods?

Before reading on

I’m not an expert in this field, but I am passionate about nutrition and health.

The articles you’ll find on my site are the result of in-depth research that I’d like to share with you. However, I would like to stress that I am not a health professional and that my advice should in no way replace that of a qualified physician. I’m here to guide you, but it’s important that you consult a professional for specific questions or medical concerns. Your well-being is important. So be sure to consult the appropriate experts and take the best possible care of yourself.

Concretely, the energy required for their digestion is greater than the energy they provide. For example, a food provides 200 calories but requires 300 calories to be digested: it has negative calories.

This type of food is particularly interesting as part of a slimming diet. Here are my top 10 best negative calorie foods.

Top 1 negative calorie foods: raw celeriac

A 100 g stalk of raw celeriac contains:

  • Protein: 1.5 g;
  • Carbohydrates: 9 g;
  • Lipids: 0.3 g;

The digestion of celery expends more calories than it provides

The best celery is firm and does not sound hollow. Choose one that is neither too heavy nor too light. Also choose a vegetable whose skin is pale and does not have brown spots.

Put the food in the vegetable drawer of the refrigerator, peeled or not. It is best to eat it within 4 or 5 days after purchase to benefit from the best nutritional values.

Eat it raw, because cooked or boiled, the amount of nutrients it contains decreases.

This vegetable has great potential as a negative calorie food because it contains a lot of fiber.

Top 2: eggplant

A 250 g eggplant — average harvest weight — contains approximately:

  • Fiber: 4g;
  • Vitamins: 1.5 g;
  • Potassium: 120 mg;
  • Phosphorus: 15 mg;
  • Magnesium: 15 mg.

Choose the eggplants smooth and shiny with sepals that stick to the touch.

Store the food in the refrigerator, but not for more than 12 hours, as it may lose its essential nutrients.

You can place it in the freezer if you absolutely must keep it for a longer period of time. In this case, wash it and cut it into slices of about one centimeter and let it immerse in water until it turns white, then add lemon juice. Finally, drain it, put it in an airtight bag and presto! in the freezer.

  • Protein: 0.90 g;
  • Lipids: 0.20 g;
  • Carbohydrates: 7 g;
  • Water: 91g;
  • Fiber: 1 g.

Negative calories increase tenfold thanks to the high presence of water.

You can store leeks in the refrigerator for over 3 weeks and in the freezer for around 12 months. If you choose to put it in the crisper, moisten it from time to time.

Before freezing it, you must first blanch it: cut the whites into pieces and bring it to the boil. The green having been previously cut should be used within 3 weeks in a soup or even in a salad as you wish.

Due to the low protein content and the high presence of water, negative calories will take your body by storm.

At the market, pick up firm peppers with shiny skin and no blemishes.

Keep them in a dry, cool place rather than in the refrigerator if you plan to consume it quickly. Otherwise, place them in the vegetable drawer for up to a week. Do not wash them and store them in a perforated bag.

If you want to keep your peppers in the freezer, wash them and remove the seeds and white membranes. Cut them as you wish. Spread the pieces on a baking sheet and leave to freeze for an hour first.
