Diet Plan – “High” and “Low” Days to Boost Metabolism! | Hardworkout Magazine
Key takeaways
- Protein stays constant at 2 g per kg of body weight for women and 2.2 g per kg for men, while fat is set at 25% of total intake on high days and 40% on low days, and carbohydrates make up the remainder.
- A quick estimate of daily calorie needs is body weight in kilograms multiplied by 30; a more precise figure comes from the Mifflin-St Jeor equation multiplied by an activity factor (PAL) of between 1.2 and 2.4.
- A deficit or surplus of 500 calories per day is the plan's recommended adjustment for losing or gaining weight.
- The plan's dietary guardrails are a maximum of 500 g of red meat per week, 300-450 g of fish per week including 200 g oily fish, at least 250 mg EPA/DHA daily, 25-35 g of fibre daily and at least two litres of water.
What are "high" and "low" days?
This is a meal plan that varies between "high" and "low" days, meaning that on high days you eat more carbohydrates and less fat, while on low days you eat fewer carbohydrates and more fat.
Why vary your calorie intake through the week?
Varying calorie intake throughout the week can help boost metabolism. Experiment and see how your body responds to different amounts of food.
A weekly plan will be distributed as follows:
4 low days and 3 high days.
Monday: Low
Tuesday: Low
Wednesday: High
Thursday: Low
Friday: Low
Saturday: High
Sunday: High For simplicity, the distribution of macronutrients is calculated as follows:
Proteins: 2 g/kg body weight for women, 2.2 g/kg body weight for men.
Fat: 25% of total intake on high days/40% on low days.
Carbohydrates: Total calorie needs – calories from proteins and fats calculated above. This diet plan is set up with high days at 2500 calories and low days at 2000 calories.
Example woman 65 kg = 130 g proteins (520 kcal)
Low day: 130 g proteins (520 kcal), 89 g fat (800 kcal), 170 g carbohydrates (680 calories)
High day: 130 g proteins (520 kcal), 55 g fat (500 kcal), 370 g carbohydrates (1480 calories) Read more about calculating calorie needs further down in the article.

How many meals a day does the plan contain?
Diet plan with 4 meals per day Each of the suggestions corresponds to approximately the same amount in calories but varies slightly in the distribution of macronutrients (proteins, carbohydrates, and fats).
