How many vegetables do you need per day when losing weight, and how can you add them without forcing yourself?

How Many Vegetables Per Day for Weight Loss

A practical norm for most people who are losing weight:

  • 400-600 g of vegetables per day
    This is usually 3-5 servings, with 1 serving being about 80-120 g.

Why this range is convenient:

  • provides food volume with low calories

  • adds fiber, which reduces hunger

  • helps you build your plate so it’s easier to maintain a deficit

Important: don’t start right away with 600 g if you currently eat almost no vegetables. It’s better to add them gradually, otherwise there will be bloating and aversion.


How to Start Walking More When You Have No Time: A 14-Day Plan Without Overload

Why It Seems Like There’s No Time

The problem is almost never the lack of a continuous 60 minutes. The problem is that walking is perceived as a separate workout, not as the sum of short segments.

Working principle: 3-6 micro-walks of 5-10 minutes a day give more than an occasional long walk once a week. And it's easier to fit into reality.


What to eat in the evening to lose weight without feeling hungry: 20 dinner options

proper dinnerWhy It’s Hard to Lose Weight in the Evening Without Hunger

Evening appetite usually increases not because something is wrong with you, but because you had too little normal food during the day, not enough protein and fiber, long gaps between meals, stress, and lack of sleep. In practice, the best dinner for weight loss is not “the minimum calories” but a clear structure: protein + volume (vegetables) + carbohydrates as needed. This approach is directly used in the dinner examples in the SIT30 menu.


How Not to Slip Up on the Weekend: Food, Cafes, Visiting Friends, and Delivery without Setbacks

company at a festive tableWhy It’s the Weekends That Break Progress

Weekends differ not by food, but by the structure of the day:

  • later wake up and disrupted meal timing

  • more spontaneous decisions: cafes, visiting friends, delivery

  • alcohol, sweets, snacks

  • fewer steps and more sitting

The result is simple: the weekday deficit is easily cancelled out by 1-2 days.

The goal of this article is not perfection but a system that lets you live normally and not slide back every week.


How to Meet Your Daily Protein Requirement Without Eating Chicken Every Day: Foods, Portion Sizes, and Sample Meals

protein foodsWhy “chicken every day” is not a must

Chicken is convenient, but there are dozens of foods with protein. Moreover, variety often helps:

  • it's easier to stick to healthy eating without breakdowns

  • easier to meet micronutrient needs (iron, iodine, omega-3, calcium)

  • lower risk of getting bored with food and starting to compensate calories with sweets

The main thing isn’t “which product”, but to have protein regularly at every meal.


Why Am I Eating Little but Not Losing Weight: 12 Reasons Without Mysticism or a "Broken Metabolism"

не худеет женщинаFirst, the important part: “eating little” does not always mean a deficit

Most often, the situation looks like this: subjectively, you’re eating less than before, but objectively there is no deficit or it is too small and masked by water.

In practice, weight “stalls” because of 2 things:

  1. There’s a deficit on paper, but not in reality due to little things

  2. There is a deficit, but progress is hidden by water, food volume, and fluctuations

Below are 12 of the most common reasons and what to do about them.
