'''A low-calorie diet''' focuses on the one thing that drives weight loss: eating fewer calories than you burn. It does not ban food groups. It manages portions and total intake. This guide explains how it works and how to run it in Loopa.
This page is general information, not medical advice.
== What it is ==
A low-calorie diet sets a daily calorie budget below the amount you burn, creating an energy deficit. Common ranges are about 1,200 to 1,500 calories a day for women and 1,500 to 1,800 for men, adjusted for your size, activity, and goal. The macro mix stays balanced.
== How it works ==
Weight change comes down to energy balance. Eat less energy than you use and your body draws on stored fat to cover the gap. Choosing filling, high-volume foods, lean protein, vegetables, fruit, and whole grains, lets you stay under your budget without constant hunger.{{cite web|title=Healthy Weight|url=https://nutritionsource.hsph.harvard.edu/healthy-weight/|website=Harvard T.H. Chan School of Public Health|access-date=2026-06-30}}
== Typical macro split ==
Balanced and flexible:
- Carbs: 45 to 55% of calories
- Protein: 20 to 30% of calories
- Fat: 25 to 30% of calories
Keeping protein toward the top of that range protects muscle while you lose fat.
== Foods to eat ==
- Vegetables and fruit for volume and fiber
- Lean protein: chicken, fish, eggs, beans, tofu
- Whole grains in measured portions
- Broth-based soups and salads
- Water and unsweetened drinks
== Foods to limit or avoid ==
- Sugary drinks and juice
- Fried and fast food
- Sweets, chips, and other calorie-dense snacks
- Large portions of oils, butter, and dressings
- Alcohol, which adds calories fast
== Who it suits and the benefits ==
A low-calorie approach suits you if you want to lose weight without giving up any food group. It is flexible and works with any cuisine.
- Simple and flexible
- Steady, reliable weight loss
- No banned foods
== Cautions and considerations ==
- Going too low on calories can cost you muscle, energy, and nutrients. Very-low-calorie plans (under about 1,200 a day) belong under medical supervision.
- Keep protein and fiber high so you stay full and hold muscle.
- If you take medication for diabetes or blood pressure, eating much less can change how it affects you. Check with your clinician and watch your [[Blood glucose]] if it applies to you.
== In Loopa ==
