The calorie of pear is 44 kcal (per100g), which is a good fruit to lose weight. The calorie of ordinary rice porridge in a rice bowl is about 100- 130 calories, so it is only 50-65 calories in a half bowl, which is much smaller than rice. By the way, millet porridge is the best food for miscellaneous grains to lose weight. Because I don't know how big your potato pieces are, I can only say that they are 76 kcal100g, which is very low, but if you want to lose weight, I suggest you steam them.
Whole wheat steamed bread 180-200 calories/piece, which is lower than ordinary steamed bread.
Tofu is 40 calories /20 grams, and the calories are also very low.
Also, according to experience, skipping dinner is very effective for losing weight, and I lost weight like this.
I hope these data are helpful to you, and I wish you success in losing weight as soon as possible!
