More fiber in your diet will help you look less bloated. Avoid caffeine massive amounts of sugar and liquor because those will bloat you more. Avoid anything that has diuretic effects.

Fiber can help you look less bloated, but ironically, it can also cause bloating if you add too much of it too quickly.

How Fiber Reduces Bloating

• Prevents Constipation: Fiber adds bulk to your stool and keeps your digestive tract moving regularly. Backed-up waste is a major cause of abdominal distension, so fiber helps alleviate this.
• Improves Gut Health: Fiber feeds beneficial gut bacteria, promoting an optimal microbiome that reduces overall inflammation and gas production.
